[[caption-width-right:346:[-These six masters will pound everything they know into Kenichi. Literally.-] ]]

A retool of ''Tatakae! Ryouzanpaku Shijou Saikyou no Deshi or Ryozanpaku History's Strongest Disciple'' released as a monthly series back in 2000.

Kenichi Shirahama is a wimp. [[EvenNerdsHaveStandards Even the]] ''[[EvenNerdsHaveStandards geeks]]'' [[EvenNerdsHaveStandards pick on him]]. That all changes when he meets Miu Fūrinji after entering high school. Miu, eager to make friends, gladly helps Kenichi with his desire to become stronger. She introduces him to Ryōzanpaku, a dojo which houses some of the most powerful martial artists known to man. Though Kenichi only sought guidance to stop being bullied, his rapidly growing prowess attracts the attention of bigger and badder foes that he has to fight... if he doesn't get pummeled through the floor tiles during training first.

Written by Syun Matsuena, ''Shijō Saikyō no Deshi Ken'ichi'' (a.k.a ''History's Strongest Disciple Kenichi'') follows Kenichi's adventures as the SortingAlgorithmOfEvil puts him up against more and more dangerous opponents. It has all the elements of Shonen action stories with a healthy dose of satire on the whole thing. The manga spans at 46 volumes and counting. The anime consists of 50 episodes and is dubbed by FUNimation under the title ''Kenichi: The Mightiest Disciple'', premiering on their channel on October 2009. Kenichi, Miu and friends appear in the MassiveMultiplayerCrossover game, ''VideoGame/SundayVSMagazineShuuketsuChoujouDaikessen''.

In 2012 a series of [[OriginalVideoAnimation OVAs]] began, starting from where the anime ended with Ragnarok Arc closure, introducing Yami and Yomi.

It is '''[[Awesome/KenichiTheMightiestDisciple very]]''' awesome.

The CharacterSheet can be found [[Characters/KenichiTheMightiestDisciple here]].

The manga has two spin offs a 4-koma gag manga ''Tekuni to Shijou Saikyou no Nakamatachi/ Tekuni and Her Strongest Friends in History'', and a manga focusing on other characters in the universe ''Shijou Saikyou no Gaiden/History's Strongest Another Stories''.

----
!!This series features examples of:
[[foldercontrol]]

[[folder: Tropes A-C]]
* AbsoluteCleavage: Renka (Year 2) & Mikumo. Occasionally Shigure. Clothing damage does this to many others.
* ActionGirl: Every female fighter.
* ActionGirlfriend: Miu. And to her credit, she's still a much [[WeakButSkilled better fighter]] than he is.
* ACupAngst: If you value your life, you will ''not'' bring up Kisara's lack of boobage. Keep in mind, this is only relative, as while Kisara is probably on the smaller end of average, just about every major female fighter in the series has a huge chest.
* AdultsAreUseless: used and subverted; in most of Kenichi's fights his masters stand on the sidelines, even joking and gambling on the outcomes, even if his life is in danger. This is because they believe that a good master stays out of their disciple's fights. It's subverted to hell and back whenever Kenichi is attacked by a master class or something: they'll step in and beat the life out of whoever attacked their disciple.
** Played straight with the staff of Kenichi's high school, who seem completely unaware of the massive gang activity right under their noses, and his parents, who are oblivious that their son has a habit of getting into life-or-death battles with skilled martial artists from arround the world.
* {{Alcatraz}}: The Big Lock, where they intend to hold all of Yami.
** CardboardPrison: The only thing keeping Masters like [[spoiler: Diego and Alexander]] from breaking out is their honour as Martial Artists. It doesn't, however, stop them from stepping outside for a stroll.
* AlienAmongUs: Everyone is sure Nijima is this. In the anime, it becomes explicit near the end, where he uses his "alien powers" to check PowerLevels, and at one point tells Kenichi "In all the years I've been studying your species..."
* AlmightyJanitor: [[CatchPhrase He is the strongest... but he is just a disciple.]]
* AlwaysSecondBest: Chisato takes an instant dislike to Miu when she's kicked from her position as the rhythmic gymnastics club's ace upon a single demonstration (at her own request) of Miu's talent.
** PowerCopying: Copying Miu's movements has actually caused her to vastly improve her gymnastics abilities.
* AnimalMotifs: Quite a few of the characters are compared to animals due to fighting style or general nature:
** Miu and Kanō are associated with birds, and are sometimes drawn accompanied with surrealistic ethereal feathers (particularly Miu; see also "Meaningful Name" below)
** Kisara and Renka are associated with cats
** Tirawit Kōkin's power is compared to an elephant's
*** He's also known as the Lion God.
** Kenichi is identified by Boris as a... [[EverythingsBetterWithPenguins penguin]] and later a Hawk!...penguin
* AmazonianBeauty: Again, every female fighter.
** Or, arguably, averted. [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v25/c225/7.html This lady]] is the ''only'' female drawn with visible biceps in the ''entire series''. Every other female, regardless of how BadAss, is pretty and busty.
*** [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/c127/11.html Freya]] is probably the best example in the series. While she doesn't show much visible bicep, she has been seen doing bicep curls with pretty huge dumbells, and she's probably got the most ripped abdomen of any woman in the series so far.
* AnnoyingYoungerSibling: Honoka
* AntiClimaxCut: Akira says he wouldn't fight the injured Apachai, or [[WouldNotHitAGirl Shigure]], and Kenichi thinks he pressed a BerserkButton. [[CrowningMomentOfFunny Instead they are flattered]].
* AntiVillain: Most of the named adolescent antagonists have redeeming qualities or sympathetic motives, to the point where it's almost surprising when one of the teen villains gets written out of the story without a minor redemption at minimum.
** Among members of Yomi, Ethan Stanley is particularly notable. He's quite polite and deferential, he tries to talk Kenichi into retiring from martial arts so he doesn't have to kill him (whereas most of the rest of Yomi would be happy to), he cares deeply about his sister... If not for Yomi's insistence on defeating Ryozanpaku, he likely wouldn't have chosen to fight.
* ArmorIsUseless: Averted. Shigure certainly would never go in a weapon fight without her trusty chain mail. And Kenichi's chain mail has also been proven very useful. Even when fighting [[spoiler:Ethan Stanley]], who is not a weapons user (because it protected Kenichi's chest from being scraped [[spoiler:by Ethan's foot]]). And, of course, Kenichi's arm guards have proved themselves as a good protection from bladed weapons as well.
** Averted in the latest chapter, when a Master Class opponent would have cleaved Kenichi in two if it weren't for his armor.
** Played straight with 98% of the rest of the cast and nearly all the Master level warriors. While its being pointed out their usefulness, it has also been stated that they don't make you invincible or ''all that'' protected and [[ShownTheirWork can be quite the detriment and/or get you killed if your style don't go with them]].
** Completely averted in recent chapters, with multiple members of the master-class weapons group Executioner's Blade wearing armor that is completely invulnerable, to the point that [[spoiler:a knight's otherwise unremarkable-looking shield absorbs fire from a 20mm Vulcan at point blank range while suffering absolutely no damage whatsoever.]]
* ArmorPiercingSlap: pretty rare, but [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/c334/18.html there is one (even lampshaded) case.]]
--> '''Elder''': Why didn't you dodge it, Ken-chan?
** If referring to the GroinAttack, it's because he was poked in the eyes. If referring to getting poked in the eyes, something [[DistractedByTheSexy caught his attention.]]
* ArtisticLicenseBiology: Kouetsuji's "pink muscle." Has basis in reality, but definitely not to the extent Sakaki explains it. In fairness, Sakaki might just not know what he's talking about.
** The Elder's "bi-vocal" ability. {{Lampshaded}} by Kisara immediately after it's explained.
** Kisara again {{Lampshades}} it with Siegfried's inhuman flexibility a few chapters later.
* AttentionWhore: Rachel "Castor" Stanley will actually stop what she's doing and contemplate a new way to steal the spotlight if she sees anyone who's the subject of more attention than she is.
* AuthorityEqualsAsskicking: This is played straight for the most part, with the leadership of Ryozanpaku, Ragnarok and pretty much every other organization in the series being based on who has the strongest fighting ability. However, it's surprisingly averted with the Shinpaku Alliance, whose commander Niijima has absolutely no fighting ability whatsoever, and yet he commands a entire gang of fighters, all of whom could beat him to a pulp with little to no effort if they tried. Granted, he doesn't get a lot of respect from most of his high-ranking subordinates, but he still maintains his position of leader regardless.
* AwesomeByAnalysis: Tirawit "Narasimha" Kōkin
** Kenichi himself, though it's more subtle in most cases. He is, after all, the second person ever to be able to utilize the complete form of Ryuusui Seikuken, which relies on reading your enemy's heart. He's even been able to predict a few killer techniques and stop them when backed into a corner.
** [[spoiler: Ogata Isshinsai as well. When Kenichi attacks him in the latest arc, not only does Ogata dodge, he then attacks Kenichi with the same move, where Kenichi was aiming, with the same power Kenichi used. He manages to copy a Mubyoshi, despite never seeing it before.]]
** In an Anime filler, the Elder gives Izumi a semi-graceful out from joining Ryouzanpaku by requiring her to do ten push-ups in order to join. Turns out she can not complete a single push-up.
* BackToBackBadasses: Kenichi and Miu do this in the D of D Arc against the Chinese team.
** And they ''attempt'' to do this in their next fight against the Elder... I mean [[PaperThinDisguise Garyu X]].
** The Pankration team also pulls this off against the Brazilian Jiu-jitsu team.
** Kenichi does this with Shigure when she takes him sword-hunting: she needed him to cover her blind spot.
* {{Badass}}: Pretty much the entire main cast, even some of the ''non''-martial artists have their [[CrowningMomentOfAwesome Awesome Moments]]. Even the ''mouse'' is badass.
** ''Niijima'' gets awesome moments. Top that!
** Even Kenichi's father has a badass moment, managing to impress Shigure with his use of a firearm.
* BadassAdorable: Chikage Kushinada
** Miu takes this up to 11 in episode 40. Turns out she's been kicking ass since she was six years old!
* BadassBoast: [[MightyGlacier Thor]] gives a good one when being attacked by [[FragileSpeedster Rimi]]:
--> "You Fool! The Soft cannot cut the Hard! No matter how fast you are, you cannot even think to match me in strength and willpower! [[PunctuatedForEmphasis I WILL NOT DIE]]."
** "God Fist" Akira Hongo gives a very daring boast right before he confronts [[spoiler:"Demon Fist" Silcardo Junazard]], later in the manga. (For context, the target of the boast was said to have fought [[BadassGrandpa Hayato Furinji]] to a standstill in the past, with no clear winner at that time.)
---> "I'll be the one to kill you."
* BadassFamily: The entire Fūrinji family. Grandpa is the Invincible Superman, Miu kicks ass with style and grace, Miu's mother was [[spoiler:the scion of an entire breeding program devoted to producing incredible martial artists]], and Miu's father [[spoiler:is ''One Shadow, the leader of YAMI'']].
* BadassGrandpa: Hayato Fūrinji
** And now [[spoiler: Freya's grandfather. In chapter 378, the kindly-looking withered old man who seemed to be senile finally made a move, and my God is his game face ''terrifying'' to behold.]]
*** [[spoiler: To further elaborate, Freya's grandfather is shorter than Kenichi due to his old age and uses his bo staff as a walking stick. He single-handedly takes out an entire group of YAMI's armed members, including at least one master class fighter. Kenichi passes out due to injuries and when the rest of the Shinpaku Alliance arrive, they find a letter from the old man explaining that he wanted to stop conflicting with YAMI, but seeing Kenichi's determination has inspired him to wield his staff once again. He leaves for a very short amount of time, returning to his dojo to his granddaughter's surprise and resumes acting like a senile old-man (with the Valkyrie squad tending to him like a friggin' harem). Cut to the final panel where the Ryozanpaku masters discuss a YAMI base being brought down recently. Three guesses as to who took it down?]]
* BadassLongcoat + SinisterShades + BeardOfEvil + flowing Badass Longhair: "God Hand" Akira Hongo of Yami
** Although, oddly enough he seems like [[PetTheDog a decent guy]], or at least not as bad as the other members of YOMI.
* BadassLongRobe: Hermit. [[RuleOfCool In a series taking place in modern Japan.]]
* BadassMustache: James Shiba
* BadassNormal: Arguably Kenichi. Despite the insane amount of training he goes through and the nearly superhuman levels of martial art skills that he acquires, his masters all agree that he has zero natural talent, and that his only saving grace is that he's willing to keep coming back for more.
** Kenichi even describes himself at one point as [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v07/c062/3.html "an extremely ordinary first year high-school student who loves reading books and growing flowers"]]... With that said, his interests do not hinder him in [[TookALevelInBadass taking many a level in badassery]].
*** Even though the masters agree that Kenichi has no natural talent for martial arts, they silently agree with Miu's observation that Kenichi is a genius at getting beaten up. [[spoiler: Given the beatings that Kenichi has taken and survived, that says something.]]
*** It's hard to tell whether it's typical ridiculous-improvement-in-short-time shonen improvement that is ignored in-universe, but Kenichi effectively gains levels of martial arts skills that enable him to defeat super-disciples trained from birth by other Masters.. in the matter of months?
*** Well, you have to note that after a hundred or so chapters Kenichi moves in with them, inorder to train more often and thoroughly. Assuming that besides going to school or to fights all his time is spent sleeping or training he likely gets a good ten hours of training in a day on school days, and likely 15-16 on non-school days. Training that kills him, requiring his Master's Chinese medicine to revive him. And then they somehow triple it once Yomi/Yami come into the picture. If you take into account that Yami doesn't want to kill their disciples as far as we have seen. Assuming that 12 months have passed that means he has something around 4800 hours of risking his life practice. Which puts him at 200 days of practice.
** As Hermit demonstrated in his fight with Berserker, even a genius cannot overcome a mountain of hard work.
---> '''Hermit''': Of course, one hundred parts of hard work may not overcome one part of gifted talent...\\
''Hermit continues to pound relentlessly on Berserker''\\
'''Hermit''': Then how about a ''thousand'' parts of hard work? What if it was ''ten thousand'' parts?\\
''Berserker swings wildly, being countered at every turn''\\
'''Hermit''': Do you know why martial arts can be passed down from thousands of years ago to now? It's because in the world of martial arts...\\
''Hermit strikes down Berserker with a final vicious blow''\\
'''Hermit''': Hard work will overcome talent!
* BarbieDollAnatomy: Applied weirdly inconsistently. When Renka and Rachel Stanley have their fight, both lose their tops at some point, but only Rachel has nipples. Miu's nips are almost always visible through her very tight leotard, but vanish when she suffers ClothingDamage that should expose them. Likewise for Kushinada Mikumo.
** Actually, there is consistency, but only in a meta-sense: No "hero" girls ever have a nip-slip, but plenty of "villain" characters do. This might be a case of "Good is pure so no touchy, but Evil is acceptable target for egregious FanService." Might be like how in America no heroes can ever be shown smoking, but badguys can have five cigars going at once and no-one bats an eye (unless the bad guys [[MisaimedFandom are more popular than the heroes]].
*** [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v40/c376/9.html So much for hero girls never having a nip-slip.]] Shigure is the heroic exception, she's both the EmotionlessGirl and regularly the InnocentFanserviceGirl, though she draws the line at Ma Kensei and his cameras.
** Averted in chapter 387.
** "Bulu"[[spoiler:Miu]] wears a teeny tiny little skirt that would normally be just perfect for giving lots of [[PantyShot panty shots]]. But instead, it quickly becomes quite obvious that she's [[VaporWear not wearing any panties]]. BarbieDollAnatomy is the only ''possible'' way this could [[GettingCrapPastTheRadar slip past the radar]].
*** She ''could'' be wearing tights. Very ''tight'' tights. That are the same color as her skin. And are seamless. SureLetsGoWithThat, shall we?
* BattleAura: of the literal variety. In particular, when one of the masters gets really pumped about something, their eyes will shine like headlights. Metaphorically. It looks really weird in the manga.
* BattleCouple: Kenichi and Miu during the D of D tournament.
* BeachEpisode: Episode 18 of Season 1.
* BearsAreBadNews:
** Kenichi experiences a bear attack while training in the mountains. Which he handles in the worst possible way, as explained via chibi people, telling you the PROPER procedure to escape bears.
** Isshinsai Ogata [[spoiler: aka Kensei of Yami]] establishes his BadAss credentials by giving said bear a NoHoldsBarredBeatdown, saving Kenichi in the process.
* BeatThemAtTheirOwnGame: Kenichi actually tries to outcrazy ''[[CrazyAwesome Siegfried]]'' of all people. [[spoiler: It... helps, sort of, but it ultimately isn't what leads to Kenichi's victory.]]
* BerserkButton: All over the place. Their enemies can have fun with this!
** Kenichi: Miu being hurt... or any one of his other friends being hurt. [[http://www.mangareader.net/historys-strongest-disciple-kenichi/186/14 For your own sake]], ''do not do that''.
*** Sure, don't mess with his friends. Yes, never mess with Miu. But if you hurt ''Honoka...'' Well... Let's just say Kenichi beat up Hermit, Loki, and a ''Goddamned shark'' to protect her.
----> '''Kenichi:''' Where is she, Hermit!? I swear, if you touch ''one hair'' on her head, you're a dead man!
*** Outright stating you want to kill Miu is the quickest way to get him to want to break you hands down.
*** Saying you'll confess your love to Miu (sincere or not) also will press it hard.
*** One guy accused him of pressing his button because Kenichi made him bleed. Kenichi had to go through training with Shigure that day to learn how to prevent himself from getting hit with a knife. Aside from mocking his terrible form and showing him what was wrong with it, Kenichi beat him senseless for insinuating he didn't know what it was like to go through hell.
*** Daimonji during their second fight in episode 7 of Season 1 stupidly destroys a lot of the plants in the gardening club, largely claiming ForTheEvulz. He then smashes the little plant that Kenichi was trying to get to grow earlier. Kenichi then gives him such a swift and deserved CurbStompBattle that the other karate club members run away in fear, and due to his TrainingFromHell, Kenichi is much faster and notices how slow Daimonji seems now compared to their first fight. [[spoiler: And the plant turns out to be okay, thanks to having a thick stem which prevented it from getting harmed when Daimonji attempted to destroy it.]]
** Miu: Hurting a kitten. "Let's kill her!" *slasher smile*
*** That's more of an "Angry Button". The real berserk button is [[spoiler:almost killing all of her friends.]]
*** *ahem!* "DAIRY COW!" *runs the opposite way*
** Hermit: {{Kill Steal}}ing
*** Being Kenichi where nobody can see you.
** Siegfried: Harming his "Precious Demon Emperor" (Niijima).
*** [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v27/c239/11.html DO NOT make him lose his inspiration.]]
** Kisara: Bringing up her [[ACupAngst lack of physical assets]].
*** Or hurting a cat. She and Miu share this button.
*** Or being stupid enough to [[WouldntHitAGirl refuse to fight her]] because she's a girl.
** [[BadassTeacher Kenichi's masters]]: Kenichi being hurt/put in danger underhandedly (also theoretically for Miu).
** Shigure: Hurting her mouse.
*** Being Ma and having a camera aimed up her skirt or trying to do anything remotely perverse earns you shuriken, kunai, or sword aimed at you. This comes across as less "berserk" than "reflex".
** Apachai: Hurting animals or mentioning that you have done so in the past earns you "The Punch You Don't Let Children See" right in the...everything.
*** Same thing happens if he finds out you're doing anything bad to children. Dealing in ''child slavery'' is a real quick way for him to "forget" he was your bodyguard a few minutes ago
** Sakaki: Using dirty methods to fight in general will piss him off.
*** An adult picking fights with kids, or attacking children in general.
** Akisame: Do not insult his mustache. He can have Shigure find you if he really wants to.
** Ma: Do NOT attempt to [[DistractedByTheSexy distract him]] by [[ClothingDamage STRIPPING]] [[PapaWolf his daughter]] Renka. IT WILL NOT WORK.
** It's implied that the Ma family live by the code "be true to yourself" and this applies in any extreme way they feel like it should. So, in theory, doing ANYTHING that angers Renka or Ma will press their berserk button.
** Honoka: "Bullying" Kenichi. She can't really do much on her own (even with her squeaky hammer) but she CAN control Apachai, who can do a LOT on his own.
** Niijima: Insulting his information-gathering abilities.
** Everyone else: Being Niijima.
** Renka: Touch Kenichi. Go on. Hurt him and she'll jump your ass faster than Miu.
*** Taking advantage of her habit of chasing anything that moves also sets her off.
** Chikage: Physical contact from anyone but Kenichi or her Mistress usually makes her snap straight to "Yomi Mode" and flip your ass all over the place.
** Boris: ORDERS. ARE. FINAL!!! (He has, however, learned to use loopholes if he really feels like it.)
** Rachel Stanley: Steal her spotlight. There are no depths she won't sink to to get it back. Stripping is a valid method for her. Along with stripping YOU and making up blatant lies about you.
** Ethan Stanley: One rich man joked about buying Rachel for kicks. Ethan punched his head through a closed car window for it.
** Kagerou: Calling him by any nickname which refers to his excessive tallness, his flat nose, or his urchin hair.
*** If you'd just follow his handy guide pamphlet, you'd be just fine.
** "God Hand" Akira Hongou of Yami: He wasn't pleased at all when he found out someone killed his disciple. He was LESS pleased when he found out it was some random-ass soldier with a gun.
*** Insulting said deceased disciple will result in him [[ImpaledWithExtremePrejudice stabbing his hand through your skull]].
** "Fist of Destruction" Alexander Gaidar of Yami: Pointing a gun at him will make him shout "Don't point that filthy metal at me!" and give you a death glare which he is all too happy to follow up on.
** "Demon Fist" Junazard Silkwat of Yami: Failing to meet his expectations can cause him to do things like bury you in an avalanche. It's been implied he doesn't mind killing his disciples if they screw up once.
* TheBerserker: Not the character ''named'' Berserker, but Apachai and Kisara when she uses Nya Kwon Do.
** In chapter 399 we learn that [[spoiler: Apachai is actually ''not'' a berserker. He seems like a berserker, but he has complete control over his strength and movements, which is how he's been able to follow Katsujinken. Although, it's been implied he only managed to gain full control after almost killing Kenichi waaay back in chapter 32 or so.]]
** Additionally, any fighter who can't control theor Dou power can become a berserker.
* BigBallOfViolence: [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v19/c166/9.html Ground spinning fist ball attack!]]
** Honestly, a [[{{Woolseyism}} better translation]] would be "Rolling Boulder Barrage" or "Rolling Ball of Fists!".
* BigBrotherMentor: Gender flipped: Freya is a Big Sister Mentor to Kisara.
** Played straight, in backstory, with Apachai and [[spoiler:Agaard]].
* BigDamnHeroes: Kenichi saves the day a few times. However the real trope examples are his masters who occasionally jump in.
** Hilariously averted in episode 7, when Sakaki wanders by while Miu and Kenichi are surrounded by 9 guys. He gives one thug such a vicious DeathGlare that the thug's glasses breaks and he collapses from the sheer awesomeness. Sakaki then criticizes and corrects Kenichi's stance, then walks away without actually doing anything. Later he thinks that his training helped, [[spoiler: when in actuality, it was a combination of Kensai's training and Miu's explanation of it for him, Miu taking out the other 8 guys by herself, and according to Kenichi himself, sheer luck, that saved the day.]]
* BigDamnVillains: In chapter 466, [[spoiler:Miu's father, the leader of YAMI who was disguised as the "clumsy" mercenary John the entire time, saves Kenichi and Miu from Jenazad's fighters.]]
* BigFancyHouse: Siegfried has one.
* BigGood: Ryozanpaku as a whole counts as they are the cornerstone of the opposition against evil and Yami, but Elder is the Biggest of them all, one of his nicknames is [[RedBaron "The Invincible Superman"]] and at one point he is described as [[WorldsStrongestMan 'The Most Powerful Being On The Planet']].
** Note that this was said when he was fighting at 0.0002% of his power... with his eyes closed.
** At one point, Sakaki declares he'll "capture [Kushinada] and present her to the Elder as a trophy". Ironic that Sakaki and the Elder are good guys while Kushinada is the evil one. Kenichi even points out how it was something a villain would say.
* BigOlEyebrows: Ryōzanpaku in particular.
* {{Bishounen}}: Ma Kensei in his youth is a prime example. It's even [[LampshadeHanging lampshaded]] by [[http://www.mangareader.net/historys-strongest-disciple-kenichi/32/13 Kenichi.]]
** [[http://www.mangareader.net/historys-strongest-disciple-kenichi/56/8 Kenichi can see roses.]]
* BitchInSheepsClothing: Natsu Tanimoto is one of the few male examples.
** Subverted, he's actually a {{Jerk With A Heart Of Gold}}/Type A {{Tsundere}}.
*** But only after you get past the initial BitchInSheepsClothing front, so it's sort of zig-zagged.
* BladeReflection: Turned to practical use for Shigure.
* BloodKnight: Too many to name. Most of them villains. But a few heroes like Sakaki tilt strongly this way.
* BoisterousBruiser: Sakaki. What freetime he doesn't spend training is spent getting drunk, or riding his motorcycle, and he loves fighting to borderline BloodKnight levels.
* BoringButPractical: Kenichi doesn't have the kind of advanced moves or styles that many of his opponents have, and while he has his awesome moments, strictly speaking he's just using the basics of martial arts. However, this is precisely the kind of martial artist BruceLee stated was the most fearsome...
* BrainwashedAndCrazy: [[spoiler:Miu, thanks to Jenezad,]]
* BrattyHalfPint: She can be extremely amusing as well, but sometimes Honoka can be so annoying that you start to hope Kenichi will throw her over the Ryōzanpaku walls out into the street.
** Or, if you're feeling ''really'' cruel, you could throw her ''in'' to Ryozanpaku with a sign around her neck that says "Train Me."
* BreakingTheFourthWall: Get's broken by the Laughing Fist in chapter 323.
* BreatherEpisode: Episode 10 of Season 2 is fairly light hearted compared to the previous episode arc where Kenichi was fighting to protect his sister.
* BunnyEarsLawyer: The series is overflowing with them, but Siegfried really takes the cake. He composes music while fighting (once even [[HumanNotepad using a fallen opponent as a music sheet paper]]), and he even goes into withdrawal when he goes without composing for too long. He even took a prayer wheel as a master.
** Kii Kagerou seems like a monster who cuts everything around him for fun, but turns out to be completely useless without his sword, and even throws away his pride to beg for it back.
** [[LittleMissBadass Kushinada Chikage]] really has a SweetTooth. It's enough to [[DefusingtheTykebomb distract her from her scheduled fight with Kenichi.]]
* ButtMonkey: Koga. You'd feel bad for him if he weren't such a little prick.
* BrickJoke: In the mini arc where Miu befriends Kisara, Apachai mentions that he once owned a cat. Nearly 300 chapters later, in a flashback to Apachai's past, we see the cat. [[spoiler: It's a ''tiger''.]]
** Early in the manga [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v11/c093/12.html Apachai demonstrates his]] FinishingMove. Over 300 chapters later [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v43/c404/13.html Kenichi uses it to end his fight with Tirawit Koukin]].
* CallBack: Used hilariously by Kenichi. When showing Miu his knowledge of plants, he even states he's reading a book about different kinds of edible grasses. That way, the next time the Elder decides to leave him starving on a mountain, he'll be okay.
* CantCatchUp: Many of Kenichi's friends and allies in the Shinpaku Alliance begin training much harder to catch up to Kenichi. Ukita Kouzou, however, has it the worst because he failed to consider the merits of TrainingFromHell and just trained normally.
** Although it is often subverted, in that many people like Siegfried, Kisara, Natsu (who may have already caught up), and Takeda do catch up, and in a relatively short period of time.
*** It's also because, as Kenichi's own teachers point out, they all have more talent for martial arts than he does. Unlike him they're all talented individuals who also put in a fair bit of hard work. Except [[DemotedToExtra Ukita]].
*** Also at times used on Kenichi, as he can't catch up to Miu or Renka.
* CainAndAbel: Ma Kensei and his brother Ma Sougetsu [[spoiler: (Hermit's master, and apparently one of the members of Yami)]].
* CallingYourAttacks: Most of the fighters do it, yelling out loud (or thinking) the names of their martial arts moves. This takes reasonably predictable forms in combat, although in certain situations it's [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v28/c251/13.html played]] [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v28/c252/10.html for]] [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v28/c252/11.html laughs]] or otherwise [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v28/c252/5.html taken]] [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v28/c252/6.html a little bit]] [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v28/c252/7.html further]] [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v18/c156/14.html than usual]].
* CallToAgriculture: Kenichi swears off martial arts in favour of gardening early in the series. This goes [[TheCallKnowsWhereYouLive as well as you might expect]].
** Later, a defeated enemy is shown to have taken up agriculture as well.
* TheCavalry: Done in episode 21 by [[spoiler: Niijima, of all people, and]] the newly formed Shinpaku Alliance. While they didn't actually do anything aside from showing up, they do force the Ragnarok gangsters to withdraw.
* {{Calvinball}}: Whatever Apachai and Shigure are playing [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v04/c032/12.html here]] with Touchumaru. Check the middle panel.
** That's basically mouse rodeo, she's timing how long he stays on what for him is a bucking bronco.
** [[http://www.mangareader.net/historys-strongest-disciple-kenichi/265/16 How about a game involving 3-4 players, each using chess, shougi, and go pieces, respectively?]]
*** That one looks more like one guy playing three separate games (each against a different person) at once, just on a really big board that happens to work for all 3 games.
* CannotSpitItOut: [[http://www.mangareader.net/historys-strongest-disciple-kenichi/293/5 Poor Izumi]].
* CastOfSnowflakes
* CatchPhrase: "APA!" and "It's a strategic withdrawal!"
* CatGirl: Renka acts as one to throw Miu off in episode 10 of Season 2. It works briefly.
* CatSmile: A few characters display one from time to time, such as Honoka and Renka. Miu does them around the presence of cats.
* CharacterDevelopment: More than one is lead to believe at first glance. This is one of the few popular shounen manga where the character development of the main character is still the most important thing, whereas in others it's treated as secondary to the the action or plot. It's most notable with Kenichi, being the titular character, but several other characters get to shine and grow as well, even the side characters.
* CharlesAtlasSuperpower: Taken to extremes by just about every single character.
** To put it in perspective, even disciples are low level superhuman. Masters on the other hand, [[UpToEleven oh boy...]]
* ChainmailBikini: {{Justified|Trope}} against the Kyouken no Izayo in chapter 388. While not completely striperrific, it let bare her stomach and part of her thighs in contrast with her male counterpart in full body armor. But then it [[FridgeBrilliance shows that she relied in extremely fast movements, acrobatics and SuperReflexes which a full body armor would have seriously slowed her down to the point of being suicidal against a Master level]]. She still lost, but it was because Ma was far faster and an expert in armor destruction.
** Shigure will see your "Chainmail Bikini" and raise you one "allegedly-armored nigh-nudity." Her standard attire is an extremely tiny kimono worn over "chainmail" that basically resembles a fishnet shirt. She doesn't wear anything under the armor.
* ChekhovsGunman: Radin Tidat Jihan[[spoiler:'s maid, Sham. Introduced in chapters 181 + 182 with an {{Omake}} in 188, she reappears in chapter 452 following Kenichi and Sakaki, and in 453 supports them.]]
** [[spoiler:By Chapter 477, Radin HIMSELF is Back.]]
* ChickMagnet: Ukita is a not Bishounen version of this. Not only is Kisara Tsundere for him but Freya is quite obviously crushing on him. Chikage also likes to cling on him, [[spoiler: and now Shiratori is starting to show some interest in him!]]
** Kenichi himself has Renka Ma vying for his attention with Miu, who has only now started to realise her feelings for him.
* ChivalrousPervert: Ma Kensei uses his peaceful Ero will (and [[PantyThief panty thievery]]) to [[spoiler: cause a hardened assassin to regret the choices that led her down the path of a killer.]]
* ChunkySalsaRule
* ClingyJealousGirl: Miu tends to react badly whenever she thinks another girl is showing Kenichi affection, or [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v25/c225/9.html vice versa]]. This even includes his [[CoolBigSis sisterly]] SexyMentor Shigure. Of course she and Kenichi are JustFriends. Ma Renka is a more straightforward example.
** [[spoiler: Shigure may have recently somewhat justified Miu's reactions. Miu's recent serious suspicions about Shigure's feelings for Kenichi after Shigure and Kenichi's training outing together do have some weight: TheStoic seems to smile only around Kenichi, and seems to like flirting with him. Doesn't really seem like the two are just friends.]]
** Honoka acts this way towards Miu in their first encounter, and believes Miu is tricking him into staying at the dojo.
** Izumi and Miu more or less get into a CatFight (albeit verbally, complete with cat noises) in episode 23 when Izumi visits the dojo where Kenichi is training. Both girls end up trying to insult each other while [[PassiveAggressiveKombat trying not to appear like they are]]. Miu later comments that Kenichi seemed a little too eager to have Izumi join the dojo.
** Miu is not happy seeing Renka in episode 10 of Season 2, especially after the latter delays bringing her father home to spend a few days with Kenichi. Cue the masters giggling at his situation between the two girls.
* CloseCallHaircut: Happens in a fight between [[spoiler: Shigure and Kii Kagerou.]]
* ClothingDamage: Happens to Miu on more than one occasion.
** Also a large part of the battle between Renka and Castor.
*** More like a large part of ''any'' battle involving [[AttentionWhore Castor]].
*** And if it doesn't happen by accident, she'll make it happen.
*** And it doesn't have to happen in a battle.
*** And around Chapter 360, the fighter with the machete faces clothing ''devastation'' by Shigure.
** Shigure loses her chain vest in Chapter 387.
** That weapons user that Kensei fought in chapter 390.
** Pretty much everyone from Chapter 509.
* TheCollector: Fortuna.
** Also I swear Ogata's this as well, his latest target you ask? Why our hero of course!
* ColorFailure: Happens to Kenichi a lot.
* CombatCommentator: On many occasions, but the two best examples are Kenichi's final battle with Odin and the fights on the ''[[TournamentArc D of D Tournament]]''. Also worth mentioning are the two occasions where a challenger fought Kenichi inside the Ryōzanpaku dojo, in front of all Kenichi's masters who heartily commentated the fight.
* ContinuityNod: In chapter 325, Miu mentions that she hasn't infiltrated an enemy ship since she was a kid -- an event depicted in a flashback over a hundred chapters previously.
* ContinuityReboot: Kenichi the Mightiest Disciple is actually a reboot of a previous work by the same author, ''Tatakae! Ryouzanpaku Shijou Saikyou no Deshi''. It tells the same story, more or less, but isn't as deep. A number of character designs are different as well, notably Takeda and Tanimoto.
* CosmopolitanCouncil: Yami's "One Shadow Nine Fists". Although a little Japan-centric (four of them being Japanese, which includes the only female member), it includes: a Chinese, an Indian, an Indonesian, a Mexican, a Russian and a Thai. Unlike the typical Cosmopolitan Council, here it's not so much about different national costumes or accents as much about individual dressing styles of the members, which partially reflect their nationalities, partially their martial arts preferences and partially their personalities.
** This Cosmopolitan Council structure is also reflected through their disciples in YOMI, although two (and later three) of them are not the same nationalities as their respective mentors.
* CoversAlwaysLie: Happens occasionally. For example, [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v32/c290/ chapter 290's cover]] shows Siegfried and Tanimoto holding swords. Neither of them is so much as mentioned during the chapter.
* CrazyPrepared: Niijima. He has traps hidden all around town in the event he has to make an escape. Brought nearly a MagnificentBastard Level in the Data Transport Arc: [[spoiler: That CD they are protecting? It's an hour of Niijima laughing. The data is really on a USB drive. That gets chopped up by the weapons users? No problem, the data was already leaked to the internet.]]
** [[spoiler: Not to mention that the disk they're protecting is actually a back-up of the original disk Niijima made in case the original was destroyed. Basically, the internet was the fourth layer of protection.]]
** Nijima even points it out to Berserker that the reason that he's number one in Shinpaku is because he's so prepared. The crazy thing? He's actually ''right.''
* CreatorCameo: In a BrandX restaurant named [[http://www.mangareader.net/historys-strongest-disciple-kenichi/323/14 Matsuenald's]].
** Another BrandX reference: [[http://www.mangareader.net/historys-strongest-disciple-kenichi/342/16 Matsueroad]].
* CrouchingMoronHiddenBadass: There's a young pencil-pusher taking part in the [[TournamentArc D of D Tournament]]. He asks to wait a bit before the fight, he has a call from his wife on his cellphone. [[spoiler:Then he takes out the body builder in front of him with one hit. He re-appears later, too.]] Also, [[spoiler:Freya's BadassGrandpa]].
** Kenichi himself is an excellent example of this trope. He has undergone over a year of TrainingFromHell on steroids, has taken on numerous badass martial artists and yet still cowers when bullied by freshmen. Nijima even calls him out on this at one point, pointing out that Kenichi's gentle personality only seems to cause more people to pick fights with him. Oh and let's not forget that he is a devoted member of the gardening club.
*** With a large helping of BewareTheNiceOnes.
* CreepyChild: Chikage Kushinada. Subverted when exposed to flowers and sweets.
* CrossPoppingVeins: A few characters display these from time to time.
* CurbStompBattle: Kenichi is sometimes on the receiving end of one, but sometimes dishes them out.
* CutenessProximity: Kisara and Miu, wherever cats are involved. Kisara even evolves a "Cat Fu" version of her Tae Kwan Do through it.
** Miu does this with ''Renka'' because she resembles a cat so much.
** Shigure as well, except with a tank...
** Averted with [[AmazonBrigade Freya's gang]], who just use it to their advantage to catch their opponents off guard.
** Miu does it with Honoka during their first meeting as well. She's awestruck by how both siblings have the same eyes. Honoka, on the other hand, thinks Miu is using her [[BuxomIsBetter sex appeal]] to keep her brother stuck at the dojo.
* CynicismCatalyst: The memory of his sister is one of the primary motivators for Natsu Tanimoto (a.k.a. Hermit) to become stronger however he can. Then Kenichi's sister Honoka becomes his MoralityPet.
[[/folder]]

[[folder: Tropes D-G]]
* DangerousForbiddenTechnique: Seidou Gouitsu, that utilizes two Ki types and can be fatal if used for over thirty seconds.
** Kensei also utilizes one.... to win at Rock-Paper-Scissors
* DangerousPhlebotinumInteraction: Roar-As-one. It's a technique that combines Sei and Dou Ki. While it does give the character immense power for a while, the end result will normally cripple or outright kill the user.
* DangerouslyGenreSavvy: Nijima. Dear Lord... to sum up, his basic strategy is thus: 1) Make your minions [[AFatherToHisMen think you actually care for them]] and 2) don't let them know you're actually a DirtyCoward.
** There are signs that he is BecomingTheMask though. Even Nijima notes that he's been acting uncharacteristically brave and chivalrous of late.
* DarkIsNotEvil: Dou-Type martial artists, who fuel their abilities with rage and aggression, are more prone to be evil, but people who are gentle by nature, such as Apachai, Miu or Kisara, can avoid this.
** Sakaki is pretty much the most menacing and scary of the Masters but is also the most caring and protective when it comes to Kenichi: Shigure even calls him "Mother Hen" because of that.
* DeadlyUpgrade: Odin and Shō Kanō's Dou/Sei Combination: "Seidou Goui" or also called "Roar as One": [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v16/c141/11.html I think Kensei described it best.]]
* DeathByGenreSavviness: A hilarious variation. While eating his first meal at the dojo, Kenichi is leaning heavily over his food in an attempt to avoid having it stolen as part of an "eating is training exercise." One master derides this as cliche, so Kenichi stops. Unfortunately, all the other masters have decided that they like the idea...
* DeathIsCheap: played with. Kenichi never kills his opponents, but has been briefly dead many times over due to his Master's training (including right before his father visits the dojo). Fortunately, Ma Kensei is always ready with powerful mystical medicine.
** Actually, once a brief death happened to him not while training, but in a real fight. [[spoiler:Tirawit Koukin gave him a devastating blow to the chest, and not even his masters would arrive in time to save him if it weren't for Niijima giving him his special reanimation technique.]]
** Death also almost claimed [[spoiler: Apachai recently, but he came back from the dead just to protect Kenichi from a Master-Class opponent.]] By which time Kensei and Akisame got to them with their techniques.
* DefeatByModesty: Almost never works. Too many women [[InnocentFanServiceGirl just don't care]]. Rachel openly subverts the trope.
** Does work on occasion though. Miu nearly loses a poolside fight when she almost loses her top (Kenichi ends up stepping in for her), and Renka unintentionally ends up turning it against Rachel (of all people) in their fight, getting away from her at a few points by accidentally removing her top and shorts.
* DefeatMeansFriendship: Pick a non-adult villain who was defeated by Kenichi or his adolescent allies. There is a greater than 75% chance that this will come into play.
** Played with a bit in that Kenichi and Miu often befriend their enemies before any sort of final fight or in some cases long after the final fight, as well as playing the trope straight.
* DefusingTheTykeBomb: The characters attempt this with Chikage Kushinada.
* DeniedFoodAsPunishment: Miu does a variation of this to Kenichi in episode 10 of Season 2, when Renka shows up at the dojo. While she does technically feed him, she gives him a very tiny fish compared to the large fish the other characters receive, and when he asks her for a second helping of rice, she gives him exactly one grain. Renka offering to feed him her share only increases Miu's [[ClingyJealousGirl frustrations]] with Kenichi.
* DesignatedGirlFight: Since Kenichi [[WouldntHitAGirl doesn't like hitting girls]], Miu often ends up fighting female opponents.
* {{Determinator}}: the only talent the Masters credit Kenichi with is his stubbornness and never giving up.
** : Siegfried. The man went without sleep for three days straight after being summoned by Niijima, refused to stop looking for him and his comrades, [[spoiler:flew a plane SOLO through a practical MacrossMissileMassacre, survived it getting blown up, POWERDOVE through the missiles, coming to an epic, if less-than-graceful landing, and proceeding to destroy two members of the Capoeria team.]] Earlier than that, he kept reviving himself from Ma Kensei's sleep acupuncture out of sheer force of will. NOTHING will stop him from coming to the aid of his friends and his master.
** And then there's Tanimoto, Mizunuma, and Takeda.
*** Tanimoto has a damn good reason why he never gives up. He promised he wouldn't. Whenever it looks like he will lose a fight, the memory of his sister keeps him fighting. The only fight he lost was against Kenichi, and that was because of blood loss. He fainted while standing up, preparing to attack Kenichi again.
* DeusExitMachina: Both averted and played straight at the same time. While Kenichi's masters are almost never actually indisposed whenever he happens to get into a big fight (in fact, there's usually at least two or more watching his fight, and usually wagering on it), they almost never intervene in the battle, even if Kenichi's life is in danger. Justified by their stance that a good master should not get involved in the affairs of his/her disciple. However, they have stepped in before, when actual master class combatants show up.
** Chapter 409 sees [[spoiler: the Masters of Ryozanpaku taking an indefinite leave-of-abscence from the Dojo, leaving Kenichi and Miu to their own devices, leaving nothing but an explanatory note. And plans for Kenichi's continued training, of course.]]
* DirtyCoward: Nijima, but he's just so ''good'' at it that it loops back around to LovableCoward.
* DirtyOldMan: Ma Kensei
* DoesNotLikeMen: Kisara tries to pull this in chapter 383, [[BlatantLies not that anyone's going to believe her.]] She repeats it in chapter 423, then promptly averts it by trying to pry details of her relationship with Kenichi out of Miu.
* DontSneakUpOnMeLikeThat: This is a reflex conditioned into Miu through years of martial arts training: she always throws anyone who touches her (or, God forbid, grabs her) from behind.
* DoubleStandard: Kensei and Renka do not let each other get any "fanservice". Kensei's case is being able to look at naked or nearly naked women. For Renka, it's being able to spend time with Kenichi alone. Renka's presence can make her dad cling to the nearest large object to stop her from dragging him back to China. Kensei hides listening devices in Renka's bells so he can spy on her.
* DullEyesOfUnhappiness _ Kenichi displays these in episode 6 of Season 1 as he tells his family he's going to spend the weekends at the dojo. His father immediately suspects the dojo is actually a cult, and immediately tries to head out there with his gun "Sebastian". But his mother conks him on the head and knocks him out before he can leave the house.
** Hermit displays them too after his fight with Kenichi in episode 9 of Season 2, but in his case its because he passes out from a combination of blood loss from a stab wound, and Kenichi's attacks.
* DumbMuscle: Apachai is the Death God of Underground Muay Thai and can crush rocks into dust with his bare hands. He also appears to be mildly retarded. But he's more of a Savant, he just can only fight, learn facts about animals, and break things.
** Partially subverted. Due to Honoka's extreme skills with Othello (more better known as Reversi), Apachai has become so skilled that he nearly beat Akisame, a highly-skilled Othello played.
* DysfunctionJunction: Many members of YOMI and Yami.
* EatingTheEyeCandy: [[HeroicBuild Seriously]], doesn't matter what [[HotMenAtWork you're]] [[BeachEpisode doing]] or [[FormFittingWardrobe where you are]], the cast will either lose their shirt or show their attributes one way or another. Taken to eleven with Hayato who can make ''Kimonos'' [[PaintedOnPants form fitting]] and use a [[LoinCloth Fuindoshi]] in any of the BeachEpisode
* EstrogenBrigadeBait: All the fighters in Kenichi Verse and in all the Flavors: Normal (Kenichi), Bishonen (Tanimoto, Shō Kanō), [[ButNotTooBlack ex]][[MotherRussiaMakesYouStrong otic]] (Kokin, Takeda). Then you get to the Masters and one chapter characters... there is ''at least'' one example for every taste.
* EekAMouse: Freya
* EliteMooks: For the Good guys you have [[AmazonBrigade The Valkyries]], who are a team of highly skilled [[ActionGirl action girls]] that are far stronger than the average fighter but not as strong as the main fighters.
* EnemyCivilWar: [[spoiler:Yami and Yomi eventually degenerate into this, with the "rebel" faction aiding Ryōzanpaku and Shinpaku.]]
* EnemyMine: Kenichi teams up with [[spoiler: Boris— against some of ''his own men!''—]] to save Ono-sensei.
* EvenEvilHasLovedOnes: This appears to hold true throughout the various arcs. Some Ragnarok members were TrueCompanions such as Thor and Siegfried. YOMI has Rachael and Ethan who are loyal siblings. This is however ironically most apparent in YAMI. There are various masters sharing an almost paternal bond with their disciples such as Alexandar and Boris or Agaard and Koukin. Some of them are even an out and out ParentalSubstitute like Akira and Shou or Mikumo and Chikage. The last part cuts both ways, some YOMI disciples faithfully search for their missing mentors when their defeated masters are thrown in a secret jail.
* EvenEvilHasStandards: Most of the Master-class opponents follow a particular code of conduct. They generally do not attack someone of the Disciple class, they do not interfere in a bout between Disciples, they do not team up with each other to fight another Master and above all they protect their Disciples. Even most of the [[BigBad One Shadow Nine Fists]] follow these rules and those Masters who break them tend to be of the CardCarryingVillain variety.
** After Kisara breaks Freya's staff into short, pointy sticks, she worries that the weapons are now even deadlier. However, Freya decides not to fight any longer, since she feels fighting with those things would be a bad code of conduct for her as a martial artist. She didn't want to kill Kisara, just beat her up a lot. Of course, the fact that Kisara landed a pretty powerful blow to her head probably helped Freya to cut the fight short as well.
* EverythingsBetterWithPenguins: According to YOMI member Boris Ivanov's perception, Kenichi's animal motif is a penguin. That later [[{{Pokemon}} evolves]] into a hawk... penguin. Yeah.
* EverythingsBetterWithSpinning (and several of its subtropes): Siegfried.
* EvilMentor: Yami is an entire organization of these.
** Each member of Yami has [[spoiler: had]] a single disciple who is [[spoiler: was]] a YOMI member. Kensei-sama in particular seems to relish Evil Mentoring. He inspired Hermit to be a ruthless martial artist, molded Odin into a killing machine, and [[spoiler: has ''twice'' attempted to make Kenichi his disciple, and has shown no signs of giving up]].
* EvolvingCredits: Changes around episode 16 in Season 1.
* {{Expy}}: Kenichi's father looks remarkably like {{Golgo 13}}. And he ''loves'' guns.
** [[AnimeChineseGirl Renka]] seems to be one for [[RanmaOneHalf the anime version of Shampoo,]], what having purple hair, a job as a waitress at a restaurant owned by a relative, and a romantic interest in the main character. Her [[AnimalMotifs Cat-like mannerisms]] may be a nod to Shampoo's [[BalefulPolymorph curse]] as well.
** Many fighters in this series seem drawn as if they were {{Capcom}} rejects and wound up here.
* ExtremityExtremist: Ikki Takeda (Boxing); Kisara Nanjo (Tae Kwon Do); Koga the Kicker.
** Takeda took this even further than the common type of example when he first fought Kenichi; because his left arm was paralyzed, he could only use his right.
** Kisara needs a little more explanation. "Tae kwon do" ("kicking & punching arts") does emphasize kicks more than most hard martial arts, but it doesn't completely neglect punches and neither does Kisara entirely.
* ExpectingSomeoneTaller: Most challengers' response to meeting Kenichi.
* EyeCatch: Becomes more blatant with Miu FanService in Season 2.
* EyepatchOfPower:
** Kajima Satomi. The eyepatch (as well as the [[ScarsAreForever scars]] all over his body) is a symbol of his high level of combat experience, particularly learning to cope with defeat. Yet to be revealed whether he's really missing the eye.
** James Shiba. Confirmed: he did in fact lose his eye in a fight with none other than the Kajima's master himself (who is the leader of Yami).
** Shigure's foster father, master Kosaka, who polished her weapon fighting skills and whose surname she inherited.
** One of the members of the Chinese kung-fu team on the ''D of D Tournament''
* FaceFramedInShadow: some members of Yami are initially shown like this. The most notable example of this is, of course, their leader, whose face was not shown until Chapter 466. See also InTheHood below.
* FamilyFriendlyFirearms: No. 20, the girl with the goggles that follows Loki around, uses a gun sometimes. However, she points out that it's just an airsoft gun, so while it won't kill whoever she shoots at, she says it'll hurt like heck.
* FanService: Relentless and in many forms, for both male and female fans.
* FanServicePack: Miu's breasts grow from 'just about plausible' to 'how can you move without black eyes?' between chapters 267 and 305. [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v36/c334.5/5.html It's handwaved/justified in an omake]].
** Renka gets an equal boost in [[http://www.mangareader.net/historys-strongest-disciple-kenichi/309/5 her next appearance]], [[{{Stripperific}} and a new dress]] [[AbsoluteCleavage that can't contain them properly]].
* FashionableAsymmetry: Kisara's one-legged jeans and Jenny's weird one-legged dress.
* FightMagnet
* ForeignExchangeStudent: The Stanley siblings, Rachel and Ethan( Americans), Boris (a Russian). Tirawit (a Thai) also technically counts, but in his case there is little or no racial gap, and the cultural gap is not so prominent.
* ForeignFanservice: Rachel
* {{Foreshadowing}}: [[spoiler: [[http://www.mangareader.net/historys-strongest-disciple-kenichi/188/17 Remember when Apachai said that he was going to throw away his life to protect Kenichi? He did.]] Well, almost.]]
** [[spoiler: In the D of D tournament]] Akisame says there is a Jujitsu technique that lets you throw your enemy without using your hands but he hasn't taught it to Kenichi. Cue around 100 chapters later Akisame throwing [[spoiler: Alexander Gaidar]] without ''touching'' him.
** Remember when Shigure took out seven weapons users at once with ClothingDamage? Awesome, right? [[spoiler: Recent chapters put her in a similar situation... against seven weapons ''masters.'' She doesn't end up so lucky this time.]]
* ForgottenFirstMeeting: [[spoiler:Miu was a little girl that Kenichi met who first sparked a desire to get stronger... Something Kenichi completely forgot by the time he first takes Miu's offer to train at the dojo. Of course, Miu apparently knew right away and didn't feel the need to bring it up when they meet again.]]
* ForgottenFriendNewFoe: [[spoiler:Odin]] to Kenichi.
* FormFittingWardrobe: Many characters, women and men alike; women like Miu and Renka have their attires skintight (no matter if it's pratical or not) to point out their beauty and crank up the {{Fanservice}}, not surprising since the series is targeted at males, but the big muscular men are also like this; Hayato, Sakaki, Apachai and many others wear impossibily tight clothes to show off their statuesque bodies.
* FragileSpeedster: Rimi, so much so that when she fought Thor (a perfect example of a MightyGlacier) She couldn't hurt him because of his toughened body and huge muscles. Conversely, he couldn't land a shot on her because she was so fast his attacks couldn't hit her.
** This may have been fixed with Rimi's newest training session in the mountains with Kensei from YAMI.
* FriendlyEnemy: Kenichi to all his opponents at first at least. He tries to avoid fighting like the plague and just makes friends with YOMI's members. This strategy is starting to work on Chikage, the first person he got a genuine shot at trying it on. Niijima even acknowledges it as a valid strategy to be friendly on the outside.
** Chikage has gone from thinking, "God I wish I could kill these idiots," to, "They're amusing, and I don't want Band-aid dead." She literally ''hates'' everyone else in the world minus her mistress. She tags along on anything they do and even fought against Yami's armed division alongside the Shinpaku Alliance.
** Ethan Stanley: Is extremely polite to everyone, earning him a lot of friends. He even takes Kenichi out for tea.
** Rachel Stanley: Is flamboyant as all can get and flirts with anyone for attention. She doesn't even mind being groped by Kenichi once, replying "ohh, be gentle~"
** Boris: He was also fairly passive when at school. Especially when Ohno Sensei is involved.
** Koukin: At the end of his battle with Kenichi, admits he can't bring himself to hate Kenichi, who admits the same about Koukin.
** Hermit: Is still technically an AntiHero, but he will work with Kenichi and the Shinpaku alliance when given next to no other choice. Especially when Honoka is involved. He has the entire "I am the only one allowed to defeat you" Complex with Kenichi and doesn't appreciate when people make claim to his targets.
** Takeda: When he was a villain, was pretty laid back and was the least likely to start a fight, usually that was Ukita, who had a fuse shorter than a microbe, he got better though.
** Kisara: When she was a villain, she would talk to Miu about cats once they figured out she had an affinity for them, without need for restraint, because they mutually loved them to bits.
** The Pancration Team Leader: He's very friendly to Kenichi despite being his possible opponent.
** Agaard: Is extremely friendly for an enemy, outright helping Kenichi against the barbarian sword user after his fight with Apachai.
** Renka Ma considers Miu her enemy for Kenichi's heart, but doesn't mind working with Miu if the occasion calls for it.
*** Kensei Ma, despite being a self proclaimed hentai, pervert, ero lover, dirty old man etc. Prevents Renka from having any alone time with Kenichi. HE can't stop their "training accidents" where Kenichi gropes Renka (It's her fault). But he uses his skills so he can peek on Shigure and give her and Miu a good slap on the ass whenever possible. Renka in turn does the same thing and tries to stop him.
* FriendToAllChildren: Apachai
* FriendToAllLivingThings: Apachai, who can apparently talk to them as well, such as asking a seagull where Niijima may have landed after the boat he was on was stranded, or which horse to bet on at a horse race.
* GagBoobs: most of the girls are very *ahem* 'blessed', but Miu's the one who gets most of the fun poked at her for it.
** [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v37/c346/5.html Kushinada Mikumo's breasts]] are each bigger than her head. Which is probably why she can never close her top...
** This has definitely gotten worse as the series progressed. In the beginning Miu was called a "Dairy Cow" by Kisara and "Big Boob Girl" by Honoka; yet at this point, Miu isn't even in the top 3 named characters in chest size, lagging behind Shigure, Mikumo, and Rachel.
** Around ch. 292 Miu got a FanServicePack (hinted as puberty) and grew almost to the size of Shigure. Then Shigure started accumulating clothing damage...
* {{Gainaxing}}: Miu in the Anime.
* GambitPileup: The entire Yami Data Transport Arc is one of these.
** To elaborate: The CD Ryozanpaku obtained in Okinawa got stolen mid-transport, allowing Yami to frame them and causing them to disperse. However, Nijima had a back up of the CD and, after the Shinpaku Alliance saved Honmaki, they headed for the mountain villa of a government official on their side to turn the situation around. Unknown to them, a bug had been planted in Honmaki's cellphone which allowed Yami to send a group of weapon users and Rimi to chase after them. The Shinpaku split up so that one group stalled while the other went to the congressman. Rimi was able to run past the stalling group, forcing Miu to chase after her. Despite that, Rimi managed to steal the CD and began to run away, but is caught by Miu. Thor appeared in the middle of their fight and accidentally broke the CD. The good news there is that the CD was actually a dummy, and Nijima had the real backup in a USB. Only it turned out the congressman was actually a master weapon user from Yami and destroyed the USB. At that point, it turns out Sakaki had been guarding Kenichi and Miu since the very beginning and took out the master. The master taunted them by saying Yami still won because the data was not exposed. In the end, no matter what Yami did, they had lost since before the arc started because [[spoiler:[[CrazyPrepared Koetsuji had Nijima had uploaded the information to the internet.]]]]
* GeniusDitz: Apachai can remember and [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v34/c313/4.html recite in full]] information about animals, and can also beat everyone except Honoka at Othello.
* GilliganCut: Ukita invites Chikage to a Shinpaku meeting, she refuses. He then says they're going to a pastry buffet and this happens:
-->'''Chikage''': I won't be soiled. ''(GilliganCut to her stuffing a piece of cake in her mouth)'' I won't be soiled!! Starting tomorrow.
* GetAHoldOfYourselfMan: In 448, [[spoiler: Nijima gives one of these to Kenichi when the latter actually starts ''punching himself'' over not protecting Miu. Nijima reminds him that that's why he started training in the first place, and that [[YouAreNotalone he's got friends who care about Miu too]]... [[JerkWithAHeartOfGold all whilst beating Kenichi with a folding chair]].]]
* GirlOnGirlIsHot: Whenever Renka and Rachel fight one may end up with a nosebleed due to their habit of stripping each other as they fight.
* GiverOfLameNames: Siegfried and his "Canon" (round in the english dub) attack. Kenichi [[LampshadeHanging points this out immediately]] to him.
* GivingUpTheGhost: When Kensei pursuades Kenichi to join him to peek in on the hotsprings expecting to see Miu and Shigure, they eventually find out it was Hayato Furinji in the hotspring, who saw through the whole plan. He scared Kenichi so hard that his ghost's ''ghost'' [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v05/c038/22.html gave up the ghost.]]
** It happens to Kenichi on a regular basis.
* TheGlassesComeOff: Odin.
* TheGlassesGottaGo: Miu is a subversion of {{Meganekko}} because she inverts this trope.
* {{Gonk}}[=/=]HumanAliens: Most characters agree that there's no possible way that Niijima can be human. One [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v03/c023/2.html omake]] suggests that his [[BizarreAlienBiology insides are just as bizarre as his external appearance]] (his heart is ''hairy'').
** Also noteworthy that Niijima does nothing to disabuse this. In the English dub of the anime he frequently refers to his "alien powers" (his ability to hide, escape from fights, and read people's moods and expressions), and in one of the closing episodes when he reveals his over-arching plan to Kenichi he uses the phrase "your species" when talking about people in general. Well, what does that make you?
* GoodOldFisticuffs: Takeda "The Puncher"
* GradeSchoolCEO: Hermit was one when he was younger, due to his adopted father dying and leaving him with control of the company. In a rather cruel but realistic twist, the company's managers and lawyers immediately conspired together to trick the young Tanimoto into signing over control of the company and its assets to them. It's implied that this stopped soon after Tanimoto was taken in by "The Great Sage Fist", as he's still fairly wealthy at the time of the series.
* GunFu: Jenny
** Kenichi's father Genji might be considered a case as well, as he's shown to be able to shoot and even reload a [[{{BFG}} bigass shotgun]] with ONE HAND.
*** While running and carrying Kenichi mind you!
**** He earns praise from Shigure, now That's Really Something.
[[/folder]]

[[folder: Tropes H-O]]
* HammyHerald: Kenichi's father for his guns.
-->ARISE, '''SEBASTIAN!'''
* HandicappedBadass: [[spoiler:Odin, wheelchair-bound]] after fighting Kenichi. Also, Takeda ''before'' fighting Kenichi.
* HandwrapsOfAwesome: All Muay Thai fighters wear these. Since Kenichi's custom-made training uniform (introduced in Chapter 145) is patched up from pieces of outfits for various martial arts (which reflects various fighting styles of his mentors), it also includes a pair of such bandages.
* HardWorkHardlyWorks: Set up straight, then subverted. During the fight between Hermit and Berserker, Hermit even acknowledges that one part talent may overcome 100 parts hard work. He then goes on to show his hard work by beating the everloving crap out of the talented Berserker, defying him to over come a hundred thousand parts hard work.
** And of course, the entire ''series'' is basically one gigantic subversion, as everyone is in agreement that Kenichi has zero natural affinity for martial arts, but still turns out to be an incredibly good fighter because he's trained so hard.
* HeelFaceReturn: Loki was once a leader of Ragnarok, and an all-around unrepentant jerkass. In a later arc, he was shown spying on Yomi for Nijima.
* HeelFaceRevolvingDoor: [[spoiler:Natsu Tanimoto]], apparently.
* HeelFaceTurn: At least seven or eight members of Ragnarok (including [[spoiler:six]] out of Eight Fists) and several of the D of D competitors. Some of the members of YOMI turn as well, but the Yami arc [[RedemptionEqualsDeath isn't so forgiving]] to its {{AntiVillain}}s in some cases. All the [[spoiler:barehanded]] members of Yomi make a HeelFaceTurn and defend [[spoiler:the Shinpaku alliance]] from the weapon-wielding members of Yomi in the Eternal Sunset Arc. This makes sense with [[spoiler:Tanimoto and Chikage]] But not the rest of them, even their masters are confused by the switch.
** Revealed to be due to a long-brewing EnemyCivilWar, with [[spoiler:Tanimoto and Chikage's]] HeelFaceTurn being the trigger.
* HeIsNotMyBoyfriend: Miu tends to deflect any questions about her and Kenichi in this manner. Nobody buys it.
* HelpingWouldBeKillstealing: This is one of the basic principles of teaching martial arts in ''KenichiTheMightiestDisciple'': it's repeatedly said that a martial arts mentor must not interfere in his (or her) disciple's fight with a non-master fighter, even when the disciple's life is in danger. However, mentors sometimes ''break'' a sparring (i.e. friendly) match when a disciple is in a serious danger. (It happened once to Takeda and once to Kenichi.)
** The one exception to this rule appears to be fighting against master level combatants. Kenichi's masters find it incredibly distasteful when one of his rival's masters attack Kenichi and take it very personally.
** The masters will also avert this trope occasionally if the situation truly warrants their intervention, such as helping Takeda to escape with a wounded Kenichi from some pursuing thugs bent on killing or at least seriously injuring him, saving Kenichi after he falls off the top of a moving bus (where he also likely could've been killed by oncoming traffic or sustained significant injuries), or attacking some sharks that are threatening both Kenichi and Honoka and are too much for him to handle alone.
* HeroesFightBarehanded: There is an example with two groups of evil martial artists: it has been implied several times that the members of the weapon division of Yami are inferior both in fighting skills and fighting ethics to the weaponless Yami fighters. Many weaponless Yami masters tend to be more anti-villains, while the weaponed Yami masters are usually presented as ruthless hoodlums.
** The notion of the Yami weapons-users being weaker is pretty strongly undermined by the Hachou Executioners Blade.
* HeroicSecondWind: Kenichi gets this fairly regularly, after he remembers some training he received earlier in the episode, or from a previous one. It doesn't always help him however, such as in his first fight against Shinnosuke Tsuji in episode 13 of Season 1. Only the timely intervention of [[spoiler: Takeda]] and later Master Kensai, prevents Kenichi from getting seriously hurt by a real opponent (as opposed to his training with the masters, where his injuries are always PlayedForLaughs}.
* HeroismIncentive: Kenichi had lost all self confidence and just wanted to run away after watching a bit of the D of D tournament. The Elder offered him the thing he always wanted: he can ask Miu out if he wins the tournament; courage ensues. Then it all but completely vanishes when, in the next match, it's revealed that the Elder has entered the tournament under the disguise of the 20-year old Garyu-X.
* HoldingHands: [[spoiler: Miu and Kenichi, for a full minute. Kenichi was excited.]]
* HopelessSuitor: Kenichi feels this way a lot of times towards Miu, played straight with Izumi towards Kenichi.
* HotBlooded: Every one of Kenichi's masters. Even Shigure is easy to fire up in her own strange, subdued way.
* HotForStudent: Though nothing explicit comes of it, there's definitely inklings of this between Ono-sensei and Boris Ivanov. Just read [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v33/c300/4.html Chapter 300]].
** Some readers see hints of it with Shigure and Kenichi. It's been said several times that Kenichi has caused Shigure to be more social, is the only one to make her smile or joke, and the only one Shigure has given her life's story to outside of her housemates. She's also rather uncaring if Kenichi sees her naked, even teasing him a bit. Since she was essentially raised by the most absent-minded dad ever, then moved into a house of martial artists and has presumably not had romantic contact with anyone before, that's saying a lot.
*** [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v32/c292/14.html See here]] two pages later he sees her [[WhenSheSmiles smile]] for the ''second'' time so far. (First time was [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v06/c046/15.html when she taught him to swim]] ''248 chapters'' before.) Dawwww.
* HotMom: Miu's mother shown in later flashbacks is nothing short of gorgeous. And insanely strong. One could posit that Miu is basically her mother with blonde hair and be spot on. Hell even their mission outfits are nearly [[Film/MyCousinVinnie iiiiIIIDENTical]].
* HotterAndSexier: After the Ragnarok arc, the series began to ramp up the Fanservice little by little, reaching the point in which only BarbieDollAnatomy keeps one from immediately realizing that Miu was [[spoiler:GoingCommando when she was [[BrainwashedAndCrazy controlled]] by Junazard]].
* HugeGuyTinyGirl: A non-romantic example would be [[http://www.mangareader.net/historys-strongest-disciple-kenichi/106/10 Miu traveling with her grandfather as a child]].
** Ukita and Chikage seem to be developing into this.
*** Ukita and [[{{Tsundere}} Kisara]], in a romantic example. Of all the (teenage) members of Shinpaku, he's the second largest, and she's the most petite.
** Also Tanimoto and Haruka.
** What, we're already forgetting Honoka and Apachai?
* HumanOutsideAlienInside: Parodied with Nijima.
* IAmSpartacus: A variation in chapter 161, to protect Sigfried from the YOMI assassin demanding Kenichi (who wasn't yet there), many members of the Shinpaku Alliance claim to be Kenichi.
* ICallItVera: Kenichi's father Genji calls his shotgun "Sebastian". His double barreled over-and-under shotgun, that is. He has a pump shotgun he calls "Maximillian". And a hunting rifle he calls "Rotowski".
** Also Kagerou, the AxCrazy swordsman from the Yami's weapon division, calls his sword "Setsunmaru" and talks about it as if it were a person.
** Shigure calls a tank she wanted to adopt Catleya.
* IfYoureSoEvilEatThisKitten: Kanō Shō [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/c259/10.html gets tested/educated]] [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/c259/11.html this way]] by his {{Evil Mentor}}s from Yami when he is still a child.
* IHaveYouNowMyPretty: [[spoiler: Jenezad manages to kidnap Miu during Hongo and Sakaki's Duel, and is taking her to an undisclosed location to teach her his martial art.]]
* IKnowYoureInThereSomewhereFight: Kenichi attempts this with Ryuto at one point. [[spoiler:He fails.]]
** Kenichi is currently locked in another one with [[spoiler:Miu, brainwashed by Jenezad to teach her Silat. So far, he's attempted using the first moves Miu taught him on her, and the... [[ThanksForTheMammary unorthodox method]] by which he broke her out of her UnstoppableRage before. Both have failed. He finally managed to.]]
* ImpossibleShadowPuppets: An early chapter-opening image in the manga shows Shigure doing a shadow puppet of Apachai (who will be starting his tutoring of Kenichi in said chapter) against a spotlight to scare Kenichi... And her hands look like she's just doing a dog or something.
* ImpossibleTask: Takeda is so determined to become James Shiba's disciple that Shiba gives him two [[ImpossibleTask Impossible Tasks]] just to get rid of him. But Takeda, surprisingly, fullfills them all. To Shiba, this is the first sign that it's actually his [[YouCantFightFate destiny]] to take Takeda as a disciple.
* ImprobableWeaponUser: Shigure, who successfully managed to defeat several armed (female) mooks by breaking their weapons and causing clothing damage ''with a wooden spoon.''
** Later topped by Hayato Fūrinji when he used [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v28/c251/13.html armed soldiers]] [[GrievousHarmWithABody as giant shuriken.]]
** Koetsuji fought a sculpting master by resculpting an angel sculpture into a jizo ''in mid-air'' and throwing it back at him.
* IncrediblyLamePun: When Nijima dubs Kisara's cat-styled Tae Kwon Do "Nya Kwon Do" in the middle of the D & D tournament, the entire coliseum is stunned into silence.
* IndyPloy: '''Every''' "plan" Kenichi's masters concoct.
* InformedFlaw: A lot of mention is made of Kenichi's utter lack of talent. Yet he surpasses people who also train and are supposedly more talented in incredibly short periods of time. Also invents and mixes his own styles and can copy his Masters' styles.
** As noted above in HardWorkHardlyWorks, it may also be that Kenichi ''is'' talentless but puts so much work and effort into his training (whether he likes it or not) that it is the primary reason he can excel as he does.
** You have 6 absolute masters of their arts, all of whom co-operate so that their training feeds off each others, schooling a {{Determinator}} in TrainingFromHell cranked UpToEleven. They also state the fact it takes Kenichi as long as he does to get as good as he does under such circumstances is proof of his lack of Talent.
*** This is backed up by other martial artists as well. Takeda started out at roughly Kenichi's strength without his good fist, started his own personal TrainingFromHell much, much later than Kenichi, and only had one Master. Nonetheless, he's still sitting on even ground with Kenichi, and even managed to learn Ryuusui Seikuken on his own, which is one of a hundred and eight abilities created by the Elder, who has only ever trained Kenichi. That's right, Takeda was able to learn something created by the Invincible Superman, completely on his own, even if it's unreliable for him.
*** The masters themselves have said that Kenichi isn't entirely talentless, he's just completely untalented in physical matters; instead his talent IS that he's the ultimate {{Determinator}}, pushing himself farther and harder against the odds than anyone else would (though it helps that they keep forcing him to go through it). As stated before, too, his {{Determinator}} qualities may also extend to his {{Constitution}}, since he can seemingly take more damage than anyone in the series, going so far as to actually survive a few attacks from a Master level weapons-user.
* InsultOfEndearment: Takeda "The Puncher" and Kozo "The Thrower" manage to use their monikers very touchingly in the dub after both complete their HeelFaceTurn (s) (managing to save Kenichi (for both), save Takeda and Kenichi (for Kozo)), and both upright quitting Ragnarok, reaffirming their friendship and promising to help each other out. Prior to this, their monikers were being used rather beratingly by their superiors.
* InTheHood: Hermit in his first appearances as a member of Ragnarok. Also some members of YOMI are initially shown like this.
** [[spoiler: including Moon who is a character that is later replaced by Hermit after a position challenge.]]
* IrritationIsTheSincerestFormOfFlattery: In the second-last episode of the anime, Kenichi starts imitating the fighting styles and personas of his masters to break through the "Gungnir" of Ragnarok's First Deadly Fist, Odin. Sakaki is furious at Kenichi's portrayal of him, and while Kensei Ma isn't angry, he still gets upset at Kenichi's portrayal of him.
** Subverted with the other three masters, though. Kōetsuji takes his portrayal philosophically (and with a hint of pride), Appachai finds it funny, and Shigure is excited when she sees Kenichi imitating her.
* IUhYouToo: Sort of. In Chapter 423, [[spoiler:Kenichi clearly indicates how he feels about Miu, but says he wont say it aloud until [[DeclarationOfProtection he's strong enough to protect her.]] Miu, for her part, says that she's aware, and reciprocates his feelings with a light kiss on the cheek.]]
* JerkAss: Haruo Niijima, AKA Mr Plot Device for making sure Everyone Who Knows How To Fight is pissed off with Kenichi.
* JerkWithAHeartOfGold: Shio Sakaki, who plays this trope as straight as can be.
** Tanimoto might count, too, though the jerkiness is extreme and the gold is a tiny nugget he'd really like to get rid of.
*** He's something of a JerkassWoobie.
* KickTheDog: Tirawit Kōkin's "tactics" during his fight with Kenichi. See MadeOfIron below for more details.
* KilledOffForReal: [[spoiler: Shō Kanō and Tanaka.]]
* KillingIntent: All over the place, up to the point where sheer killing intent will knock a {{Muggle|s}} out.
* TheKidWithTheRemoteControl: Niijima has an almost Final Fantasy style summoning of Siegfried whenever he is in a pinch. Probably the best example is [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v32/c297/17.html this]]
* KnowledgeBroker: Niijima has elements of this, appearing to be omniscient with all the information he possesses, though he gathers all this info for his own selfish ends rather than turning a profit.
* KungShui: An epic example of this happens during the fights in the Yami base on Okinawa: a destruction of not only walls, but also ''floors'' of a luxury hotel.
* TheLancer: Hermit
* {{Leitmotif}}: In the anime, Siegfried is associated with A Night on Bald Mountain, and his [[VerbalTic constant "la-la-las"]] are actually sung to go along with the background music as it plays.
* LeParkour: Kenichi's second week of training with the Elder uses this to teach him something else.
* LetsGetDangerous: The most triumphant example would be Freya's grandpa handing everyone their asses.
* LightIsNotGood: Sei-type martial artists, who fuel their abilities with calm and clarity, can still be pretty sadistic. Koukin is a Sei-type, for example.
* LightningGlare: Sparks fly briefly between Miu and Izumi in episode 23.
* LikeBrotherAndSister: Particularly hilarious is Miu's legendary [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/c124/7.html response]] after Kisara insinuates that Miu is lonely because Kenichi is absent. Yeah, right, ''"like a little brother"''.
*** More like a dog actually...
**** Made even funnier because one of the Mooks points out "That's kind of mean..."
* LimaSyndrome: The YAMI researchers who are trying to learn the secrets of blacksmithing from their captive [[spoiler:Shigure]] end up becoming her apprentices. The scientist in charge realizes what's going on and is even more afraid of his "prisoner" as a result.
* LimitedAnimation: It's mediocre when compared to other studios' (especially Creator/{{TMS|Entertainment}}', as they animated the series) work. [[MotionlessChin Characters' chins do not move when they talk]], it is very inconsistent, and their facial features do not align where they should on their faces at some points. Hayato, who is probably 8 feet tall, is suddenly drawn as a literal giant, whose head is twice as large as another characters, simply when the gag calls for it. Sometimes, this is subverted, as there are also scenes that feature almost Disney-like squash and stretch!
** The second season clearly has a much higher budget, [[AnimationBump especially during the fight scenes]].
* LoveBubbles: When Kenichi first meets Natsu Tanimoto, Hermit, [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v07/c056/9.html he sees roses.]]
* LoveLetter: Kenichi receives one in episode 2 of Season 2. Miu isn't too happy about it, and Kenichi's initial excitement towards getting one doesn't help either. [[spoiler: Turns out that the letter was actually written by [[MagnificentBastard Niijima]] while disguised as a girl, and the letter was to all 3 of his "generals" in order to ensure they arrived at the restaurant where the meeting between Ragnarok and the Shinpaku Alliance met. The three guys are understandably pissed off, but Niijima is much too fast for them to catch.]]
* LoveTriangle: Kenichi, Miu, and various characters. Most obviously, when Renka tricks Kenichi into taking her out to a pool, the chapter is called [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v11/c095/ Triangle Relationship]].
** A little with Rachel as well: consider her obssesion with him when they first meet.
** Seems to be going on with Ukita, Freya and Kisara: Ukita has a crush on Kisara (which she knows about), Freya likes Ukita (which he doesn't know about yet), and Kisara's actions around Ukita are somewhat suspect.
*** Miu [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v41/c380/11.html notes this]] [[LampshadeHanging by name]] when Freya goes around giving gifts to Kenichi and Ukita. [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/c380/10.html Ukita's has a ribbon on it.]]
**** Not to mention that Shiratori may be part of it now too. [[http://www.mangareader.net/historys-strongest-disciple-kenichi/489/15 but not as you might think]]
** Kano and Takeda also end up in love triangles with Miu and Kenichi.
* LukeIAmYourFather: [[spoiler: Miu]] may be set up for this trope, seeing as how [[spoiler: her father is the leader of Yami]].
** There is another similarity with the TropeNamer (''Star Wars'') in the fact that Hayato gives Kenichi [[spoiler: the arm guards that belonged to Miu's father without telling him the bitter truth about the former owner, which resembles Obi-Wan's giving Anakin's lightsaber to Luke]].
*** [[spoiler:Chapter 459 reveals that Kenichi's aware of the arm guards' history]].
* LuminescentBlush: An odd twist in that it's [[{{Badass}} Sakaki]] who does this when Kenichi calls him "Sensei" the first time after he moves in.
* MacGuffinMelee: Miu engages ElegantGothicLolita Rimi in a running battle over a disk with vital information about Yami. [[spoiler: It turns out to be a [[RedHerring fake.]]]]
* [[MadScientist Mad Martial Artist]]: Oogata Ishinsei has no qualms using his students to test [[DeadlyUpgrade deadly upgrade mentioned above]], and to keep that student around as an [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v37/c344/6.html "unusual test case".]] There is also [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v40/c371/5.html a hint that he experimented on colleagues]] just to gain greater understanding of Martial Arts. He even has an [[EvilLaugh evil laugh]].
** [[http://www.mangareader.net/historys-strongest-disciple-kenichi/407/11 Then there's Akisame...]]
---> "Then let's cheat God! Let's cut up the cycle of rebirth; let's distort nature!! The human technique that challenges the Second Law of Thermodynamics head on!!! '''That is known as medicine!!!!!'''"
** As Kensei put it:
---> '''Kensei:''' This man's spouting some crazy logic.
* MadeOfIron: [[JustifiedTrope Justified]] in that almost all characters have a lot of training in how to take hits. [[SubvertedTrope Subverted]] when [[spoiler: Tirawit tricks Kenichi into fighting the school Karate club. Since none of them had any real defense training, his usual efforts left them all hospitalized.]]
** Kenichi gets a special mention: his method of fighting seems to be based on wearing the opponent out by letting them beat him bloody. Most other fighters use this strange concept of dodging, but Kenichi just takes the abuse. Hey, it worked for Muhammad Ali.
** May also be somewhat literal, in Kenichi's case: several of his opponents have commented that hitting him is like hitting a lead block.
** Kensei of [=YAMI=] once offered to train Kenichi because of this trait. Kenichi might not have as much talent as other disciples, but he's ideal raw material.
* TheManBehindTheMan: The role of BigBad seems to have gone from [[ActionGirl Kisara]] to [[ForgottenChildhoodFriend Ryuuto]] to [[EvilMentor Ogata]] to [[spoiler: Saiga]].
* MaleGaze: Frequently. [[spoiler: In chapter 559, Takeda complains about not being able to see anything happening in front of him. [[{{BabyGotBack}} Because Freya and Kisara are laying in the boat in front of him.]]]]
* ManChild: Apachai Hopachai.
** Kenichi's father too.
* MarshmallowHell: Miu's a big girl, so [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v41/c379/10.html when she hugs him in relief...]] Though Kenichi clearly enjoys it.
** Miu does it to Honoka when she first visits the dojo.
* MartialArtsDoNotWorkThatWay: Averted. Syun Matsuena had done a very extensive and thorough research (at one point traveling to Thailand for this very reason) and it [[ShownTheirWork shows]]. The only possible gripe is the fact that the levels of ability (moving faster than a bullet, breaking cement with a Fist, cutting steel with a ''[[MundaneMadeAwesome game controller in the form of a sword]]'' and so on) can't be done in real life.
** The abilities of master-class martial artists become increasingly unrealistic in the 300+ chapters, with characters in full plate [[spoiler:sprinting on water and deflecting sustained fire from an Aegis ship defense cannon with a shield]] or throwing axes [[spoiler:so that they ricochet off surfaces and return to his hand]] - and that's just the weapons users, not counting, well, the Super Man.
* MartialMedic: Koetsuji and Kensei. They even make a profession out of it, running osteopathy and acupuncture clinics, respectively.
* MartialPacifist: Kenichi. Ryōzanpaku supports this stance overall but stresses he needs to learn to be ''really'' good in order to keep it.
* MegaManning: [[spoiler: Kenichi utilizes the techiniques of his masters to break Odin's guard.]]
** [[spoiler: It's also what the master's of the dojo are teaching to Kenichi. He is being taught Kempo, Aikido, Muay Thai, weapons usage... just remember that [[AlmightyJanitor he's just the apprentice.]]]]
* {{Meganekko}}: Subversion: Miu wears glasses to tone ''down'' her appearance. [[spoiler:When she's called out on this 'dishonesty', she stops wearing them.]]
** The straight up example would be Yūka Izumi, Kenichi's fellow member of the gardening club.
** Another straight example: Ono Kyōko, the cheerful ShrinkingViolet English language teacher.
* MeaningfulName: Miu's name actually means "beautiful wings" or "beautiful feathers", which is in accord with her bird-like fighting movements.
* MegaTonPunch: Kenichi is on the receiving end of these when he's training, usually with Apachai. Averted when he's in an actual fight with someone who's really looking to seriously hurt or even kill him. Some attacks do send him flying, but unlike the training sequences where its PlayedForLaughs, he often ends up getting bloodied and bruised pretty badly from those hits.
* MementoMacGuffin: Kenichi's Yin-yang pin, which he got in a trade with [[spoiler:a six-year-old Miu]].
* MissingMom: Miu's, [[spoiler:through death, implied to be at the hands of her father.]]
* MotorcycleJousting: Shigure once does a motorcycle joust against an armored horseman.
* MsFanservice: Most of the females have their moments, but... '''''Shigure'''''. Oddly enough, while she violently rebukes DirtyOldMan Ma Kensei whenever he tries to get candid shots of her, she doesn't seem to mind if Kenichi gets an eyeful...
** Kensei's daughter Ma Renka, too.
** Meta-example in Rachel Stanley, as she [[AttentionWhore does this]] to get the attention of male characters within the story.
** See also: Miu's [[FormFittingWardrobe outfits]]. She gets more screentime than Shigure, too.
*** In recent chapters, Freya seems to have challenged Shigure for the title of Ms Fanservice with gusto. A battle that Shigure is more than willing to fight.
**** Nearly every female character above the age of 14 in this series becomes this, with most female characters sporting massive breasts and either skin-tight or extremely brief outfits. (The only exceptions are background or side characters like Izumi, and Kisara who has normal female proportions.) Even [[spoiler:Shiratori, who dresses like a man and has an apparently masculine voice... right up until she's seen in a bikini]]. Try not to imagine how hard it is to fire a bow with breasts the size of your head and a skin-tight bikini top.
* MuggingTheMonster: Most masters of Ryouzanpaku have gotten mugged at one point or another.
** Boris's dojo destroyer team gets confused by Ryouzanpaku's sign [[labelnote:*]]since it's written in the traditional right-to-left direction[[/labelnote]], and mistook it for a run-of-the-mill dojo.
** Some delinquents attempt this on [[TheDragon Tirawit]] [[VillainWithGoodPublicity Kokin]], amazingly enough [[NotWorthKilling he didn't kill them]].
*** No, instead he just took over all the school gangs: save for Shinpaku: and taught them Muay Thai... which doesn't sound so bad until you read MadeOfIron...
* {{Muggles}}: While all superpowers are nominally of the [[CharlesAtlasSuperpower Charles Atlas]] variety, there is a vast chasm between martial artists and ordinary people, including street thugs.
* MundaneMadeAwesome: [[http://www.1000manga.com/Historys_Strongest_Disciple_Kenichi/388/10/ EPIC ROCK,PAPER,SCISSORS complete with glowing eyes and slow motion ]]
** The unveiling of Sebastian and the other guns owned by Kenichi's father have all the pomp of the launching of the ''[[SpaceBattleshipYamato Yamato]]''.
** Sakaki drinks beer by KARATE CHOPPING THE BOTTLE NECK OFF. Possibly a reference to real-life karate master Masutatsu "God Hand" Oyama.
*** The above may be more of a MundaneUtility example, since he's pretty casual about it.
* MyKungFuIsStrongerThanYours: Used a lot against mooks and elite mooks but disciple and master fights tend to be decided by a mistake rather than strength.
** The biggest reason Miu doesn't fight much in the beginning is that she is a lot stronger than everyone else.
* MysteriousParent: Miu's father.
* NebulousEvilOrganization: Yami. As explained over various chapters (including [[http://www.mangareader.net/337-23660-6/historys-strongest-disciple-kenichi/chapter-154.html here]]), they have their hands in everything from weapon sales to the military to governmental influence, and enough funds to potentially be a self-sustaining nation. Their intention is to preserve and promote the "Satsu-jinken" (killing fist) style of martial arts, a goal they've pursued since their initial formation after World War II because several martial arts masters died during that war. Additionally, [[WeAreEverywhere the group is known by several names worldwide]], including "L'Obscurite" in France, with "Yami" name being its Japanese name (both words mean "darkness" in their respective languages).
* NiceJobBreakingItHero: If Miu hadn't taught Kenichi his first dodge and fighting moves so early then Kenichi wouldn't have won his fight with Daimonji and Ragnarok would probably have just left him alone.
* NoDoubtTheYearsHaveChangedMe: It took quite a while for Kenichi to recognize [[spoiler:Odin]] as his ForgottenChildhoodFriend.
* NoodleIncident: When Honoka asks what happened to the first boat they built in episode 18, none of the masters try to answer it. Apachai tries to but his mouth is kept shut by Kensei. Considering the extensive damage they do to the dojo when training Kenichi, viewers can probably figure that one out pretty easily however.
** Comes up when discussing Siegfried's "Immortality."
--->'''Sakaki:''' This could be just the thing I need to test my skills! I've never fought a zombie before.\\
'''Elder:''' ''I'' have.
*** And nobody even ''tries'' to ask him for an explanation. At all. None of the masters say anything which suggests they know what he's talking about, either. [[SeenItAll They all just go back to the conversation.]]
* NoseBleed: Strangely enough Kenichi suffers from this at first from Shigure, rather than Miu.
* NoSocialSkills
** Shigure is a borderline example. She spent her formative years in the wilderness with her swordsmith father; though he did love her he was so absent-minded that he ''never even bothered to give her a name''. This (lack of) upbringing probably contributed to her present-day lack of social graces.
** Chikage falls under this as well; having endured a strict upbringing for most of her life under her master, she is revealed to have difficulty adapting to normal life. Hence her transformation into child mode whenever she encounters sweets or toys. This comes to a head when she is forfeits the challenge to Kenichi because she was distracted as a result of being invited to a birthday party.
** Apachai too, to a degree. In fact, in the earlier chapters, he's the only one that's regularly seen hanging around Shigure ([[DirtyOldMan the only one without a camera]], anyhow).
* NotDistractedByTheSexy: Shigure's enemies are only concerned that she apparently didn't have a weapon while taking a bath.
* NotJustATournament: The "D of D Tournament", where both the bad guys (who organized the event) and the good guys are engaged in various activities behind the scenes which are as important as the tournament itself. The climax of these background activities takes place simultaneously with the final tournament battle between Kenichi and Kanou.
* NotSoWeak: Kenichi, who is still afraid of delinquents despite ''officially'' being the strongest disciple around.
* TheObiWan: Akisame Koetsuji
* ObliviousToLove: Kenichi has a bad case of this. It mostly stems from his devotion to Miu and the fact that he still cannot wrap his mind around that girls might like him now that he has taken several steps of Badass. The list below are only people that have admitted liking him in one form or another.
## Renka: this is in part because she ends up hurting him every time they meet. And because he's a generally nice guy to her.
## Izumi Yūka, the girl in the gardening club. She's has a crush on Kenichi since he joined the club, but between Miu showing up and other factors every time she gets the courage to ask him out he does not hear her.
## [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/c330/7.html Li Raichi]], the skating girl: this one is at least slightly understandable in that they only met, like, twice.
## Chikage Kushinada. Though its more that he's the only person she has ANY emotional attachment to because he treated her like a normal girl, as opposed to a genius he should be admiring. She has a MAJOR internal conflict when the possibility of Kenichi getting killed shows up during his battle with Ethan Stanley.
## Rachel Stanley: this one may just be Rachel being her usual spotlight-hogging self, but she doesn't mind when Kenichi gropes her, and she kissed him once. Which is a helluva lot further than Kenichi's gone with anyone else, including Miu, even if it wasn't by his own free will. Ethan does tell Kenichi to take care of Rachel when he leaves, so it's likely that Ethan thinks Rachel has feelings as well.
## Shigure. She never said it directly, but the other masters have noted that she really acts more comfortable around Kenichi than she ever did with any of them. This says a lot given that she's lived with them for many years, and has only known Kenichi about 1-2 years in canon. She'll try and castrate Ma for looking up her skirt, but will take a bath ALONE with Kenichi if given the chance.
** Miu is also pretty oblivious to her own feelings towards Kenichi. Which in turn he is oblivious to her true feelings. [[TwiceShy Don't they make quite the pair?]] [[spoiler: As of chapter 423, she's acknowledged his feelings and returns them.]]
* OhCrap: Kenichi when Honoka [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v22/c189/5.html asks the forbidden question.]]
** [[http://www.mangaeden.com/En/History%27s%3D_%3DStrongest%3D_%3DDisciple%3D_%3DKenichi/191/10/ Kenichi's face just screams this.]]
** Chapter 400: [[spoiler: Apachai just got a hole punched THROUGH HIS CHEST... and pulls off a punch in 406 though he is already dead?]]
** Chapter 463: Junazard gets [[http://www.mangareader.net/historys-strongest-disciple-kenichi/463/16 this expression]] [[spoiler:when Hongo breaks a piece off his mask with an attack Junazard assumed had missed]].
* OlderThanTheyLook: CreepyChild Chikage Kushinada's Yami master, Mikumo Kushinada, is apparently a senior citizen. Given that she looks like [[http://www.1000manga.com/Historys_Strongest_Disciple_Kenichi/316/04/ this]], this is somewhat jarring. Justified by her 'Kushinada style' anti-aging methods, making Chikage's actual chronological age somewhat vague...
* OneManArmy: Ryozampaku's and Yami's masters. [[WorldOfBadass Every single one of them]].
** Furinji Hayato, aka "The Invincible Superhuman" deserves a mention of its own, especially after [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/c384/1.html this chapter]].
--->'''[[TheHero Kenichi]]:''' T-This is insane, shishou! Even though it's [[BadassGrandpa the elder]], taking on the American military alone...\\
'''[[CynicalMentor Akisame]]:''' [[BadassGrandpa The elder]]? Ah, [[PaperThinDisguise Garyuu X]]. Don't worry, he won't hurt them.\\
'''[[TheHero Kenichi]]:''' [[LampshadeHanging That's what you're worried about?!?]]
* OneSteveLimit: Averted by Kensei Ma and Kensei of Yami. The latter is a title, while the former is a given name. The ''Japanese pronunciations'' of the Ryouzanpaku master's name and the Yami master's nickname are the same, but they're written with different kanjis. (And then, there is the controversy over which way Chinese names should be written in translations: whether to approximate their Chinese pronunciations or to write them the way they're pronounced in Japanese. Ma's surname is actually pronounced "Ba" in Japanese, and some translations rendered it as "Ba".)
* OnlyKnownByTheirNickname: Most of Ragnarok members didn't have their full names revealed until after the D of D tournament.
** Lampshaded with Thor. Apparently, the characters were as shocked that he had an actual name as you are.
** Loki and his underlings, the most notable being [[YouAreNumberSix Number 20]].
** Also, know who Hayato Furinji is? He's the Elder, or Garyu X! No, really, I think we only hear his name once.
* TheOnlyOneAllowedToDefeatYou: Pretty much the extent of Kenichi's and Tanimoto's "friendship".
** Also pretty blatantly spelled out with Masters Sakaki Shio and Akira Hongo.
** Agaard and Apachai apparently have had a mutual understanding of this for a while.
* OnlySixFaces: Sort of averted, but lampshaded in the anime.
-->'''Thug:''' We're looking for a girl who looks just like you. Except she's taller, and her [[HairColors hair]] and [[CommonEyeColors eyes]] are different, and she's not so scrawny.
* OpposedMentors: Kenichi once finds himself in a situation where he can choose between Hayato's and EvilMentor Ogata's mentorship. It's very tempting for Kenichi because previously Hayato seemingly abandoned him and Ogata seems like a very friendly person. The catch is that the TricksterMentor Hayato himself put Kenichi in this situation to [[SecretTest test his moral priorities]].
* OpposingCombatPhilosophies: Katsujin-ken, Life Giving fist and Satujin-ken, The Killing Fist.
** Katujin-ken users believe one should only use Martial Arts to defend themselves and/or others and to never take a life.
** Satujin-ken users believe one should use Martial Arts to prove their strength and that battles to the death are the only way to know a fighters true strength.
** There is also a third option, The Path of the Demon, in which the Martial Artist just wants to fight and destroy without cause or reason until they are eventually killed.
* OppositesAttract: Miu and Kenichi, while their personalities are pretty close, their fighting styles, technique, Ki, and even their abilities to learn are completely opposite.
** Miu: Uses high flying acrobatics, speed, grace, and advance level techniques to fight. She is also a user of Dou Ki making her an aggresive type of fighter. Miu is an InstantExpert and is able to learn new fighting styles and techniques in a very short amount of time.
** Kenichi: Uses strength, power, and ground augmented low level basic techniques to fight. He is also a user of Sei Ki making him a Passive type of fighter. Kenichi is something of a slow learner and often doesn't grasp the styles and techniques he's taught until the last possible second.
* OrdinaryHighSchoolStudent: The manga is always quick to remind the reader how ordinary Kenichi really is. Usually while he's in the middle of something really, really crazy. It's practically a RunningGag
-->"I am Shirahama Kenichi, an extremely ordinary first-year high school student who loves reading books and growing flowers. But, for some reason now, '''I'm locked in a desperate battle on top of a speeding bus!'''"
* OverprotectiveDad: Shirahama Genji's a little worried about what exactly Ryōzanpaku Dojo is doing to his son. [[TrainingFromHell The concern is entirely justified]]. His solution?... [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v13/c111/21.html Not so much.]]
* OutGambitted: This keeps happening the Yami Data Transport Arc, to the point of reaching GambitPileup levels. [[spoiler: In the end, no matter what Yami did, they had lost since before the arc because [[CrazyPrepared Koetsuji had Nijima upload the information to the internet.]]]]
[[/folder]]

[[folder: Tropes P-Z]]
* PalmFistTap: Seen every now and then; see the trope page for more details (and an image).
* PaperThinDisguise: Garyu X anybody?
** To be fair, nobody buys it.
** Except for [[TheDitz Apachai]]. Well, [[ObfuscatingStupidity maybe.]]
* PapaWolf: All of the masters at Ryōzanpaku really; they never really get serious even against other master classes until someone hurts Kenichi or Mui or the mouse.
** Sakaki shows an example of this: after seeing the scene on [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v17/c150/12.html this page]], [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v17/c150/14.html this]] [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v17/c150/15.html hap]] [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v17/c150/16.html pens]] [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v17/c150/17.html .]]
* PerfectPlayAI: [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v28/c257/13.html this]] certainly looks like it
* PetTheDog: Nanjo Kisara (aka Valkyrie) when she buys food and milk to feed an abandoned cat in a back alley.
** A double example shows up in a flashback. Shou Kanou [[spoiler:spared the bird the [=YAMI=] master told him to kill and faked its death.]] His master Akira Hongo [[spoiler:saw through Shou's deception but let him keep the bird as a pet anyway.]] This foreshadows a present-day example: [[spoiler:Shou also faked killing Fortuna's team of slave children and helped them escape.]]
* PleaseWakeUp: [[spoiler: [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v43/c401/7.html APACAHIIIIIII!!!!]] ]] And he ''does'' wake up. [[spoiler: EVEN WITH A HOLE IN HIS CHEST.]]
* PointlessBandAid
* PostVictoryCollapse: This happens quite regularly, as one might expect from a cast composed largely of [[{{Determinator}} Determinators]] who insist ICanStillFight even when they're eighty percent dead on their feet.
* PowerCopying: Kisara uses Miu's method of moving like a feather to beat Freya.
* PowerLevels: A very loose form in that there are only three; Disciple, Expert, and Master. Three more levels inside each these is Low, Middle and High these lesser three though are not as easy to gauge.
* ThePowerOfFriendship: When the Shinpaku Alliance members are getting beat up by Ragnarok's thugs, Loki tells them that if they give up Niijima, the rest can go. One of the Shinpaku men says that Kenichi would never abandon his friends like this, while Kenichi coincidentally arrived at the same restaurant and was trying to avoid getting involved in the mess. But despite not liking Niijima much, Kenichi (as well as Takeda and Ukita, who also happened to coincidentally arrive, see the LoveLetter trope above) pull a BigDamnHeroes moment shortly afterwards.
** Takeda does this for Kenichi after [[spoiler: his HeelFaceTurn, where Kenichi helped save his life and helped bring him to Akisame who helps restore the use of his left arm.]] He does it again near the end of Season 2.
** Kenichi is told by Hayato [[spoiler: that his ability to get people to become friends around him is his true power at the end of Season 2 in the anime.]]
** This trope is a major theme of the TournamentArc, even getting a ShoutOut as the name of chapter 213.
* PregnantBadass: Miu's mother Suzuha.
* PummelDuel: Kenichi vs Odin, via seikuken vs seikuken.
* QuirkyMinibossSquad: The Eight Fists
* RatedMForManly: Not at the start, but right now it definitely is. HotBlooded martial arts, ripped males, buxom females, everyone is badass in one way or another ? Check to all of these !
* RazorFloss: Captain K of the Black Force
* RealMenWearPink: Kenichi is a dedicated bookworm and loves growing flowers. Siegfried composes classical music and sings during battle.
* ReallyDeadMontage: [[spoiler: Apachai.]] With the twist that [[spoiler: Apachai temporarily comes back from the dead to save Kenichi from the Yami swordmaster.]] And [[spoiler: then straight up subverted when Akisame declares that he will not surrender his friend to a mere ''god.'']]
* RedBaron: The Masters of Ryōzanpaku and Yami all have one. Some good examples from Yami are "Fist of Destruction" Alexander Gaidar, "God Hand" (no, not that GodHand) Akira Hongo, "Fierce Fist God" Sougetsu Ma, "Demon Fist God" Silkwat Jenazad, and "Saint Fists" [[spoiler: Isshinsai Ogata]]. BadassGrandpa Hayato Fūrinji might have the best ones: "The Man Without Enemies" and "The Invincible Superman".
* RecurringExtra: Makoto Himeno, Izumi, the gardening club president's friend. She is often seen by herself or with Izumi while characters run around time, actually putting her screen time pretty high.
* RedemptionEqualsDeath: [[spoiler: Shō Kanō. Also a HeroicSacrifice]].
** I think this is more subverted in that he was never all that bad to begin with. He just was wearing an evil mask to survive in the organization he was in. His personality didn't change, just what we knew about him and his motives changed.
* RenaissanceMan: Kōetsuji Akisame is a master in many fields. The things he haven't mastered will be mastered almost instantly.
* TheRival: Hermit, Odin, and Shō Kanō to Kenichi; Kisara to Miu (at least from Kisara's point of view)...and those are just the unambiguous and (at least initially) hostile instances.
* RoaringRampageOfRevenge: Kenichi does it to a group of Ragnarok thugs in episode 21, after they beat up [[spoiler: Takeda and Ukita, both of whom left the gang and was going to get beat up badly for it.]] He doesn't hold back either, and really dishes out the hurt to them.
* RockPaperScissors: How Kenichi's masters decide his training order, and other trivial, nonsensical things, too.
* RunningGag: Miu's habit of throwing anyone that comes up behind her. Kenichi, other fighters, even total non-combatants. She even does it on the very first page of the manga!
** Renka instinctively "chasing moving objects"
** Someone trying to move Kenichi in some way shape or form stopping then saying "What are you, [[MadeOfIron made of iron?]] You weigh a lot more than you look!" He's also compared to a block of lead from time to time.
** Apachai answering the phone by saying he kidnapped your child, or some other terrible crime.
** Shinpaku members always asking if its okay for Siegfried to being missing from his school (he doesn't attend the same school as the rest of the gang).
* SacrificedBasicSkillForAwesomeTraining: Subtly played by the Masters of the Ryouzanpaku: Six masters of their own martial arts, all of them (except the oldest) are {{Socially Awkward Hero}}es: Akisame Koetsuji is a BrokenAce, Shio Sakaki is a JerkWithAHeartOfGold, Apachai Hopachai is a ManChild, Shigure Kosaka has NoSocialSkills, Kensei Ma is a HenpeckedHusband that ran from his family; all of them depend of Miu Furinji to run the dojo. All of them were reunited at the Dojo because they have no other place to go. Hayato Furinji claimed that Kenichi (TheHeart) united them in a true family.
** Also played straight with Miu. Up until the first episode, while she does have some good housework skills, and is a fairly excellent fighter herself, she is also a {{Socially Awkward Hero}}ine, and has no friends (due to her intense training and lack of time to spend with them) until Kenichi showed up. When Miu told Kenichi about his old, private school life, Kenichi realized she was being bullied for being TheAce. So when Miu transferred to Kenichi’s school, she invoked being a Megannekko to get a ''less aggressive'' look and changed clubs because SchoolClubsAreSeriousBusiness. When then gymnastic club star, Takashima Chihiro, asks Miu to show her skills, Miu only gets Chihiro to be TheRival and TheBully because Chihiro is AlwaysSecondBest. Miu didn't has any idea how to stop being bullied.
* SamusIsAGirl: [[spoiler: Shiratori]]
** Well, it was kinda easy to figure out, if you watch anime. Here's some [[http://www.youtube.com/watch?v=op82cjHfzV4&feature=related example]](watch parts 0.17 and 1.29).
* SaveTheVillain: Freya's [[StrawFeminist all female]] [[{{Delinquents}} mook squad]] goes looking for [[ActionGirl Kisara]]... and runs into [[LadyOfWar Shigure]]. They then decide [[TooDumbToLive it would be a jolly good idea]] to [[BullyingADragon attack her]]. Shigure calmly tells them that they are out of their league. Cue Kenichi begging Shigure not to kill the mooks. He begs her down to using a ''wooden cooking spoon'' (she'd been helping prepare supper) [[CrowningMomentOfAwesome with which she destroys all their weapons]] [[ClothingDamage (and clothes)]] [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v12/c105/6.html in a single panel]].
* SayItWithHearts: Miu loves to add hearts to the end of her sentences. Occasional Izumi Yūka does when she thinks that she in gaining ground with Kenichi.
** And Shigure when Akira dismissed her as an [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v43/c429/14.html opponent because she was a woman.]] Probably the only female fighter who has so far taken "I won't hit women" as a compliment.
* ScaryShinyGlasses / GlowingEyesofDoom: An interesting play on both tropes that [[NinjaPirateZombieRobot combines their characteristics]]. Many characters, especially the masters, will somehow project bright beams of light from their eyes when they are either REALLY serious about something, or are just being very creepy. Apachai is highly prone to it, for the former reason.
** It's explained as a sort of indicator of killing intent, or at least, intent to do something drastic, painful, and combat-related. Apachai, who never learned to hold back, is very prone to it because he still doesn't quite understand the idea of not attacking with such intent very well. Which leads to Kenichi's chronic fear of sparring with Apachai. [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v03/c023/3.html With]] [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v03/c024/2.html good]] [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v03/c024/15.html reason!]]
*** Lately it appears that the eyebeams are activated when the person is using a (near-)Master-Class technique. Siegfried (who is still at Disciple-Level) is said to use some moves that are [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v27/c238/14.html almost Master-Level]] as well as '''Niijima's''' [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v40/c377/9.html Dodging- and Escape-techniques]]. And then Kenichi decides to join in on the fun...
* SceneryCensor: Often the mouse covering up Shigure.
* SenseiForScoundrels: Kensei Ma and Sasaki Shio certainly qualify, in many ways helping Kenichi overcome his confidence issues in general, be it by dragging him along for some AccidentalPervert antics or by guzzling some beer and giving some advice.
* ShadowArchetype: Kanō to Kenichi. Kenichi embodies the light aspect of martial arts, and Kanō embodies the dark aspects. They are opposites in pretty much every way, personality and appearance-wise, yet they are also very similar in that both are students of multiple Master-class fighters and partly because of this, they are viewed as the best fighters in their individual peer groups.
* ShaggyDogStory: Apachai's backstory is told to Kenichi to explain why Miu's grandfather bought an expensive scroll on their limited budget. [[spoiler:Kenichi doesn't buy it as a reason and [[LaserGuidedAmnesia gets his mind wiped]] at the end by a technique used in the story.]]
* ShownTheirWork: Many of the fighting techniques that Kenichi learns are accurately described as well as the styles he encounters.
* ShoutOut
** To ''DetectiveConan'', in [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v38/c357/12.html chapter 357]]. Akisame lampshades this by saying he's an original character because he has different hair.
** ''{{Doraemon}}'' also has one in the same chapter [[http://www.1000manga.com/Historys_Strongest_Disciple_Kenichi/357/16/]]. There were also a few instances in prior chapters when Kenichi ran to Ryōzanpaku yelling "Doraemon!" when he needed Koetsuji's advice. In one of those instances, Koetsuji's eating dorayaki.
** ''TheFlintstones'': Apachai says Yabba Dabba Doo a couple of times.
** To ''FistOfTheNorthStar'' [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v41/c384/12.html here]].
** Not sure if it counts, but in a fansub of the anime, when Niijima uses his "alien powers" to read power levels, they are stated as being "[[DragonBallZ over 9000]]".
*** In the original manga, he [[http://www.mangareader.net/337-23671-2/historys-strongest-disciple-kenichi/chapter-165.html breaks his scouter]].
** To Hajime No Ippo is Takeda's "Double Cat-Eyed Frog Punch" bears more than a passing similarity with Aoki's upper cut version of his "Frog Punch". The only difference being that Takeda puts a spin in his fists where Aoki just does two jabs at the same time from the same crouching position. Neither of which are considered a normal frog punch, which constitutes punching with your middle finger knuckle extended and aiming for the throat.
** Hakubi translates to Pai Mei in mandarin.
** In the first episode when Kenichi wonders where Miu learned to throw people over her shoulder on instinct "at hitman school?" He has an image of what looks like Golgo13 holding a gun.
*** Look at Kenichi's Dad, then at Golgo13. He's pretty much a good guy version of Golgo with the goofyness cranked up to 11. He also has extreme skills with a gun that even Shigure said were impressive.
*** To specify, he reloaded a double barrel shotgun with one hand by spinning it after managing to chuck the new bullets into the air so they'd land in the gun while holding an unconscious Kenichi under his other arm while running from Shigure. This man is dangerous and would probably be considered a master if the series used guns as a weapon and he wasn't so goofy. He was even ballsy enough to punch Sakaki in the face, true that didn't even PHASE Sakaki, but the fact he did it certainly speaks volumes for his bravery if [[PapaWolf he feels his family is threatened.]]
** Sakaki slams a random foe ontop of a car with [[BlandNameProduct Muku]] of [[{{Vocaloid}} Hocaloid]] on it.
** Niijima is probably related to Himura of Eyesheild21. They Both:
*** Have pointy ears.
*** Blackmail EVERYONE THEY CAN FOR EVERYTHING THEY'RE WORTH.
*** Can bluff their way out of nearly any situation you throw at them.
*** Keep their blackmail info handy at all times. (Niijima has a PDA, Himura has a little black book with a bat on it)
*** Scheme quicker than most people can add 2 and 2
*** Can calculate information about their opponents with a good long stare, sometimes a short one will do as well.
*** Elongated canines
*** Scare the shit out of their "allies". Niijima because he's downright creepy, pops out of nowhere whenever he feels like it, and knows more about you than most people do by staring at you. and Himura because he's scary, trigger happy, and can somehow own a rocket launcher despite being a high school student.
** To ''Anime/CowboyBebop'' in chapter 119 where Ma Sensei threatens to force the entire dojo to only eat green peppers and beef if Akisame does not reveal what he is thinking.
** To ''Franchise/GhostInTheShell'' [[http://mangafox.me/manga/history_s_strongest_disciple_kenichi/v23/c200/12.html here]].
** In chapter 199, upon approaching the elaborately carved entrance to the fortress where the tournament's being held, Kenichi notes that it's ominous. The Elder remarks that it's like a "gate to hell". Although the art doesn't show complete detail, it's definitely a nod to Rodin's massive sculpture, ''The Gates of Hell''.
* SingleStrokeBattle: Just about any Master vs anyone who is not master level, but Kenichi got one recently [[http://www.mangatoshokan.com/read/Historys-Strongest-Disciple-Kenichi/Sugooi/378/12 fighting a disciple]] of a Yomi from the weapon division. This was after he had been hit by a master with a sword so it's also a CMOA.
* SlaveToPR: Tanimoto. Only the Shinpaku Alliance knows that he's really a BitchInSheepsClothing.
* SmugSnake: Ragnarok's Loki, who considers himself a master strategist for such things as throwing lots of mooks at the protagonists and kidnapping Kenichi's little sister. Also Yomi's Radin Jihan, who spends most of his fight shrieking about how he deserves to win because he is the king of a small nation in Indonesia and sending his own minions at Kenichi.
** All that screaming about being king undergoes a sort of FunnyAneurysmMoment, when it is revealed that his belief in his divine kingship is the only thing that keeps him from falling into a yawning chasm of loneliness.
* SneezeCut: [[http://www.mangareader.net/historys-strongest-disciple-kenichi/92/10 Kouetsuji can even tell who is talking about him by the sneeze]].
* SnipeHunt: Shiba sends Takeda on several of these before he'll take him on as a student. Takeda somehow manages to pull it off.
* SortingAlgorithmOfEvil: Delinquents < Ragnarok < YOMI < Yami (With a number of assassins/guards and non-Yami masters in there as well. These have to be taken on an individual basis, though)
* SpoiledSweet: Siegfried. It's implied that he's both a wealthy Heir and a professional composer. Niijima mentions that Siegfried is personally funding the Shinpaku Alliance with profits from the Opera he wrote about them.
* StandInParents: Miu does this once. When she applied to the high school, she gave false data about her parents (including the lie about them being still alive), because she wanted to present herself as a girl with a normal family. This backfires on her when the representatives of her school come to Ryouzanpaku to check up on her. HilarityEnsues when she eventually chooses the jerky (although good-hearted) Sakaki and the {{Lady of War}} Shigure with NoSocialSkills to pose as her parents.
* TheStarscream: [[spoiler: Loki of Ragnarok]] tries to pull this off against [[spoiler: Odin]], and has about as much success as the trope's namesake. Which is to say none.
* StatusQuoIsGod: Invoked in universe. The night when Kenichi and Miu had their [[RelationshipUpgrade Kiss]] [[AlmostKiss interrupted]] by [[MomentKiller Grandpa Furinji bursting through the front Gate]] became the "Night That Never Happened".
-->'''Miu''': Oh, you came back last night? I didn't notice at all...\\
'''Apachai''': Apachai never saw anything.
* StayInTheKitchen: Miu, mostly by Kenichi (even though she is FAR better than him in fighting).
* StealthHiBye: Happens several times.
** Kanō enjoys doing pickpocketing tricks with his hands. That's how he exchanges his earring with Miu's hairclip, for instance.
** Both Stanley siblings pull this off at various moments: Ethan to Niijima once, and Rachel once to her [[TournamentArc D of D tournament]] opponent and once to Kenichi.
** The most surprising example is Ono-sensei (the ShrinkingViolet English language teacher) doing this to Boris, which leads Boris to think that she might be a master-class martial artist. (Of course, Boris is attuned to the "killing intent" in those who approach him, and Ono-sensei ''has none''.)
* StepfordSmiler: The Yami Luchadore master "Laughing Fist" Diego, [[spoiler: or rather, the [[http://www.1000manga.com/Historys_Strongest_Disciple_Kenichi/329/06-07/ "Angry Iron Fist"]]]].
* StoryBreakerPower: Any Master Class. Even Fortuna, the weakest level of Master and regarded as trash by all other masters, takes the entire cast of secondary characters to take down, a very specific technique, and help from a [[CrazyAwesome insanely skilled mouse]].
** The last half of chapter 380 is Kenichi's masters celebrating how incredibly far Kenichi has come and how proud of him they are when Kenichi ''survived a hit from a low level Master Class weapon user''. And that's with the help of body armor and TrainingFromHell for his body's core.
* {{Stripperific}}: Miu's spandex. She's drawn nude with BarbieDollAnatomy and screen tone -- the only time you can actually tell she's not wearing BodyPaint is when she experiences ClothingDamage. Fortunately, this happens ''all the time.''
** That's nothing. Compare the first chapter with this [[http://www.mangareader.net/historys-strongest-disciple-kenichi/445/17 one]]. You can't get more blatant than that.
** A case must be made for Castor. A bikini top and a tiny skirt with a thong. That's it. Renka also likes wearing revealing dresses as well.
** Mildred Lawrence of the Hachiou Executioner Blade wears a thong and a bikini top despite the fact that she'd repeatedly snap herself across the breasts with the string pretty much every time she used it.
* StupidSexyFlanders: Natsu Tanimoto is pretty enough to [[EvenTheGuysWantHim distract straight men with the sexy]] ([[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/c056/6.html yes]], [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/c056/8.html even]] [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/c056/9.html Kenichi]])
* SuicideAsComedy: In episode 5 of Season 1, Kenichi wonders if all the masters are training him because they think he can become a good martial artist like them. They all immediately answer no in unison, causing him to immediately try hanging himself with a conveniently hanging noose on a tree, with Miu trying to stop him.
* SuperPowerMeltdown: Happens to [[spoiler: Odin]] at the end of the anime series. He has some super strength and speed for a short while, but then his body begins to break down as a result of not being able to withstand all the power flowing through him. The masters comment that this is why it's such a dangerous technique and rarely used when Miu asks about it.
* SuperSpeed: {{FlashStep}}s are there, but only the Elder has actual run-on-water, outrun-a-car superspeed.
** Well, Kenichi's other masters have been shown to outrun vehicles, and they all managed to come to his rescue by beating up a ''collapsing warehouse'' together, arriving on scene together with no lag time between their arrivals.
* SuspiciouslySpecificDenial: [[http://www.mangareader.net/historys-strongest-disciple-kenichi/188/14 Kenichi certainly did not touch Miu's hair while she was sleeping.]]
** Latest chapters give us a villain whose entire schtick is this.
* TakeAThirdOption: In episode 18, Kenichi quotes this word for word (in the english dub anyway). He's told that he can either jump off a high cliff into the water to skip his training (bad because he can't swim and probably afraid of heights), or he can face some grueling training for a few days at the beach instead. Since he figures he's going to die either way, he decides to simply run away, and ends up making things worse at the end [[spoiler: when Honoka ends up surrounded by sharks because everyone else was looking for him instead of keeping an eye on her.]]
** Kenichi does it again in episode 23 when Niijima stokes the fire between Izumi and Miu by telling the poor guy to pick one of the girls. He decides to go training instead.
* TeamPet: Touchumaru, Shigure's mouse.
* TheThingThatGoesDoink: At Ryōzanpaku
* TheUnfought: Shiratori, Kisara's Lieutenant. He had the same rank as Tsuji, and was therefore likely at a similar level of strength, but never fought onscreen. He continues to appear after the merger with Shinpaku, even attending the D of D. [[spoiler: Later Shiratori is revealed to be a girl, so maybe that's why]]
* ThisIsUnforgivable: It's a fighting series, of course this gets used, by Miu, Kenichi, even some of the masters.
* ThouShaltNotKill: The key point of contention between Ryōzanpaku and Yami; Ryōzanpaku believes in this and Yami doesn't. The main conflict of the series turns out be Ryōzanpaku trying to prevent Yami from spreading their point of view of the purpose of martial arts.
* TimeToUnlockMoreTruePotential: Generally, every moment Kenichi is not in school. More explicitly, the Black Valley arc and every other time the Elder personally trains Kenichi.
* TitleDrop: Nijima refers to Kenichi as "history's strongest disciple" after he beats up a gang.
* TokenEvilTeammate: Niijima and Natsu (Hermit)
* TookALevelInBadass: Kenichi
** Took ''hundreds.''
*** They just keep coming. Kenichi will take on weapon users with [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v40/c374/15.html zero hesitation now.]]
**** Or not: [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v40/c375/9.html Blades are Scary! Blades Are Scary!]]
*** The way they're going, Kenichi's gonna take ''millions'' by the time the series ends...
** Everyone at one point or another.
* TournamentArc: The Desperate Fight of the Disciple Tournament. "D of D" for short.
* TragicKeepsake: Miu's pocket knife hair clip, which belonged to her deceased mother. Also [[spoiler: Kanō's birdcage-shaped earring]], which Kenichi always carries around tied to his school bag as a reminder of the promise given to [[spoiler:Kanō]] that he'll protect Miu.
* TrainingFromHell: For the Masters of Ryozanpaku, there's pretty much no other kind. You wouldn't BELIEVE the training Kenichi goes through; the other characters of the manga don't. And after defeating Ragnarok and getting targeted by YOMI, his masters decide to TRIPLE his training.
** It should be noted that at one point, Kenichi's father believes that Kenichi is using the dojo as a means to slack off, and thus comes to pay the five masters a visit. They all agree to go WAY easy on him for the day... causing his father to come to the conclusion that the training has been altered for his visit. He's under the impression that the masters have been extra hard on him for the visit to prove Kenichi is working hard, when the truth is it's precisely the opposite. The training causes his father to attempt a "rescue" of Kenichi until traps around the dojo allow him to show his father just how strong he's become.
** One could easily call this tale, "Training From Hell: the Series"
* TrainingMontage: About OnceAnEpisode, in keeping with the genre. As expected from the above, some of the training is sadistically creative.
** An example: the masters observe that Kenichi's arms are only a third as strong as his legs. Their solution? Running around the block in a handstand.
* ATruceWhileWeGawk: While [[spoiler:Kenichi and Berserker]] don't actually ''stop'' fighting, the both of them ''do'' look away at the same time to see what's happening with Miu & Rimi's latest battle.
* TrueCompanions: There are several examples including the Shinpaku Alliance, [[BigGood Ryouzanpaku]], the Ancient Pankration Team and [[QuirkyMinibossSquad Freya's Valkyrie Squad]] among others.
* {{Tsundere}}: Renka tries so HARD to be one of these, but always ends up blushing when Kenichi compliments her and ends up coming out looking like a genki girl with a slight attitude. Towards Miu she plays the trope a little straighter.
** Sakaki and Tanimoto are both rare Male versions. Sakaki is even something of a Mother Hen towards the members of Ryouzanpaku.
* TwiceShy: Dear Kenichi and Miu, Just go out with each other already! Signed, The Fans.
** They DO. Kenichi even tells Miu about the Elder allowing them to date (If he won D of D), at which point The Elder lays down some really strict ground rules.
* UnconsciousObjector: Kenichi during his final epic battle against Shou Kanou on the [[TournamentArc "D of D tournament"]]. While he's fighting unconscious, the lack of moral inhibitions actually makes him noticeably stronger, which amuses his EvilCounterpart opponent.
* UnstoppableRage: [[spoiler: Miu]]
* UnusualEyebrows: Nearly everyone's eyebrows are on the atypical side, ranging from fiery to swooped and even ''lightning''-shaped.
* UnwantedHarem:
** Kenichi has a group of 4 girls all in love with him that consists of Miu, Izumi, Renka and Li.
*** The only one he shows affection for is main-heroine, Miu. Miu however, says she wants to stay as ''Best Friends'', but that doesn't stop her from falling for Kenichi as well, even if she refuses to acknowledge it.
*** Renka is part of the Shinpaku Alliance and has basically been Miu's [[LoveTriangle main rival]] for Kenichi.
*** Izumi is a lost cause due to mainly being reduced to a background character.
*** Li has mostly been OutOfFocus after her introduction arc, only reappearing on Yami's ship during the ''Master and Disciple tag-team'' arc.
** Ukita of all people has 4 girls who have shown affection for him, all of them ''much'' stronger than him.
*** Kisara, who outright plays the Tsundere for him, only really showing she cares when he's in danger, she otherwise just blushes like crazy.
*** Chikage, who has taken to sitting on his lap whenever she's around him, and she's helped him in fights.
*** Shiratori, who was recently revealed to be a girl, asks Takeda to tell her what kind of food he likes, and admits she is jealous of Kisara for having Ukita's affection. After she just beat the crap out of him.
*** Freya, who says she "doesn't mind" him when alone with Kisara. she seems to be holding back since Ukita has actively expressed his feelings for Kisara, and not her.
** Thor suprisingly has his own harem developing amongst all of Freya's Valkyrie servants.
* VerbalTic: Apachai's "APA!". Preserved in the dub.
* VillainForgotToLevelGrind: Seems to affect the early bad guys who fights Kenichi and wins the first time. In subsequent battles Kenichi seems to deliver a CurbStompBattle to them. To be fair however, Kenichi often receives [[TrainingFromHell unconventional training]] from his many masters, and most of the people he ends up in fights with are trained for competitions with rules and regulations, rather than street fighting where its often [[CombatPragmatist "anything goes"]], and unsurprisingly to Kenichi, the fights he's in at those times are street fights.
** It gets subverted later when facing Yomi.
* VillainRespect: Kenichi gets this a few times, from both members of YOMI and Yami, and it often happens to show that [[PetTheDog the villain in question isn't that much of a douche after all]]. Noteworthy persons who've shown him respect include Tirawat Koukin of YOMI and Agaard Jum Sai and Akira Hongo of the One Shadow Nine Fists [[spoiler:and more recently Berserker and the One Shadow himself]].
* VitriolicBestBuds: Kenichi has decided that he's going to be Tanimoto's best friend whether he likes it or not. Tanimoto's solution is [[SlaveToPR to play along when anyone's looking]] and [[BitchInSheepsClothing tear him a new one (verbally or physically) when they're not]].
* WakeUpCallBoss: In episode 13 of Season 1, Shinnosuke Tsuji is the first fighter that Kenichi truly has trouble fighting against. Tsuji was in the process of attempting to break Kenichi's leg when Takeda showed up unexpectedly. Its also the first time one of his masters, who normally observe HelpingWouldBeKillStealing, intervenes to save him since Kenichi was on the receiving end of a CurbStompBattle, and Takeda was unable to outrun Tsuji and his minions while also carrying Kenichi.
* WasItAllALie: A non-romantic (... [[HoYay mostly]]) version occurred when Natsu revealed himself to be Hermit. Hermit insists that it was a lie, but Kenichi was unconvinced.
* WeakButSkilled: Chikage Kushinada
** The entire Kushinada-style Jujitsu is built around this concept, being made to employ 0% strength and 100% skill.
** Koetsuji appears to be this at first. Kenichi even comments that his skinny body doesn't look very strong. [[http://www.mangafox.com/manga/history_s_strongest_disciple_kenichi/v03/c022/17.html Then we find out otherwise]].
** Also Miu. Lacks power, but has far more technique than the much stronger (physically) Kenichi.
* WhamEpisode: [[spoiler: Double Wham. Chapter 400. Apachai gets a hole punched through his chest. Will he get better? No. And then he did!]]
** [[spoiler:Kenichi getting stabbed and blasted of the building by Hongo.]]
** Next chapter: [[spoiler: Miu gets taken by Jenazad.]]
** Chapter 466: [[BigDamnHeroes Sakaki should be arriving at any moment.]] [[spoiler: It's actually [[BewareTheNiceOnes John]]. But not really... it's [[BigBad Saiga]].]]
* WhamLine: [[spoiler: Chapter 521. "You have now reached the test call service hotline..."]]
* WhenAllYouHaveIsAHammer
* WhenIWasYourAge: When Kenichi's masters want to tell him how little talent he has. ([[http://www.mangareader.net/historys-strongest-disciple-kenichi/189/4 Example.]])
* WillTheyOrWontThey: Kenichi and Miu. Even the masters at the Ryōzanpaku constantly listen to their conversations when they're alone to see if a relationship will progress.
** [[spoiler: As of chapter 423, it seems they will. [[{{OhCrap}} Too bad Hayato was there and noticed.]]]]
* WingdingEyes: Number 20 constantly has star-shaped pupils. It might be just excitement being with Loki, but it's hard to tell.
* WizardsLiveLonger: Rachel mentions that there are techniques to retain/gain youth and that just about any master of eastern martial arts ends up at that point.
** Mikumo is the most fitting, having both been mistaken for several decades younger and going by the code name Bewitching Fist.
* WouldntHitAGirl: Kenichi has a bad case of this. While it initially enrages Kisara, she eventually realizes he's not actually being sexist... he doesn't refuse to hit girls because he thinks they're weaker or less worthy, he just doesn't want to.
** Slightly averted later on. He won't punch them outright, but will grapple and use submission holds.
** This attitude is put to the test later, when an attack by [[spoiler:a brainwashed Miu]] forces him to fight back.
* WorldOfBadass: The MsFanservice YamatoNadeshiko? She stacks SuperBreedingProgram and UnstoppableRage on top of her WaifFu. The DirtyCoward NonActionGuy? His CharacterDevelopment carries him right through MagnificentBastard to GuileHero. The [[TeamPet mouse]]? Turns out he knows how to operate an assault rifle. The BumblingDad? He can reload a lever-action rifle one handed, ''a la'' [[Film/Terminator2JudgmentDay the T-800]]. So many characters have turned out to be unexpectedly badass that it's probably more sensible to ask ''when'' an given character will [[TookALevelInBadass take a level]], rather than ''if.''
* WorldOfBuxom
* {{Wuxia}}: The series increasingly becomes this as time goes on, with the plots revolving around the schools and styles of martial artists and the personal conflicts of their masters passing onto their students, a common theme in wuxia stories. They even use the phrase "Underworld" once or twice, a loose translation of the word used to describe the private world of martial artists in wuxia stories.
** Sakaki's "organ lift" secret art.
* YourApprovalFillsMeWithShame: Niijima congratulates Kenichi for being so quick to distrust what someone (namely, Niijima) says; Kenichi is [[HarshWordImpact stabbed by an arrow from the word balloon]].
* YourHeadASplode: At least in an imagine spot in an early chapter.
** [[spoiler: How Kensei kills Tanaka]]
