A 16-year-old boy who is currently in his second year of high school. On his way to school one day, Kenichi meets a girl named Miu, and the two soon become friends. At the start of high school, Kenichi joins the school's karate club, hoping to become less weak, but he is forced to do menial chores and is used as a punching bag. One day, he finally stands up to a hulking student, and the two agree to a match in which the loser will quit the club. With Miu's help, Kenichi manages to win, but he quits the club anyway. He joins the Ryozanpaku dojo, which Miu's grandfather nominally runs, and begins an intense training regime in several different types of martial arts.Kenichi is kind, compassionate, thoughtful, and moral to a fault. He is against violence and studies martial arts to protect others, and he adheres to a strict code of morals, which includes a refusal to hit women. Because of his kindness and empathy, Kenichi has made many friends, most of whom are former enemies.
Alas, Poor Villain: Despite having a serious hate-on for Shou Kano and having been in a bloody, vicious, all-out fight with him only moments before, he still displays sincere regret and sadness when Shou is fatally wounded protecting Miu, then tells Kenichi that it's up to him to protect her from now on.
Badass Normal: His masters blatantly tell him that he has no talent, but make up for it by all-but beating the lessons into him. The results have been staggeringly successful, as attested by out-classing Berserker.
Hurting or threatening to harm his friends, ESPECIALLY Miu...
Go ahead and insult his masters. I dare you.
Beware the Nice Ones: A meek young man who enjoys reading and gardening. He just wants to be friends, even if you're a member of an Ancient Conspiracy dedicated to the practice of martial art centered on kill your opponents. Push one of his Berkserk Buttons and he will fight like a rabid badger.
Boring, but Practical: 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 Bruce Lee stated was the most fearsome.
Eventually averted when he starts relying on Ryūsui Seikūken and Mubyoshi.
Combat Pragmatist: Since he receives training from a variety of masters who specialize in different fighting styles, Kenichi can often mix his fighting moves up a little bit to throw off his opponents, most of whom are trained more traditionally and mostly specialize only in one or two forms of fights. For example, in his fight against Takeda the boxer, since Takeda is trained to fight with his fists and upper body, Kenichi utilizes low kicks to attack his legs since Takeda wouldn't be expecting that (since that would be illegal in a boxing match), and therefore wouldn't be concentrating on protecting his legs.
Cowardly Lion: Scared stiff more often than not, though it won't stop him fighting. It's his master's training that really scares him. Through the wonders of character development, this is less and less the case.
Determinator: Unconsciousness won't stop him, by the end of the D of D tournament. In fact, that just worsens your chance of keeping him down, since he then surpasses the speed of thought and perfectly demonstrates the techniques that (nigh literally) have been beaten into him by Ryouzanpaku.
The Fettered: He doesn't fight because we wants to be the strongest, or because he enjoys fighting; he fights to protect others. And if you're the person others need protection from, you will find that he is much, much stronger than he initially seemed.
Fight Magnet: Justified by Niijima in chapter 5: After Kenichi defeats Karate Club bully Daimonji, he attracts the attention of the Karate Club captain Chukuba; after he defeats Chukuba he attracts the attention of Ragnarok… and after he defeats Ragnarok, he attracts the attention of Yami. God only knows what will happen when he defeats their disciples.
Forgotten First Meeting: When Kenichi was a kid, he and Ryuto met Miu. After seeing Miu defeat the thug trying to assault a kind old lady, both Ryuto and Kenichi vowed to become strong, but Kenichi forgot the fact and that it was Miu who traded him the Yin Yang badge he carries on the neck of his shirt all the time for a cat badge, as a remainder of said promise.
Hero with Bad Publicity: No thanks to Niijima, who often acts like J Jonah Jameson and either gives misinformation or else exaggerates Kenichi's wins, making Kenichi seem more like a common thug than a guy who wants to protect people.
Human Pack Mule: To Miu whenever she goes shopping for groceries. This, of course, doubles as a part of his Training from Hell, and his mentors often force him to carry some extra weights on those occasions, just for the sake of training his strength and endurance.
Iron Butt Monkey: He's one during training with the various masters. Averted during actual fights with bad guys.
Love at First Punch: Unintentional but still. His meeting with Miu is related to this trope but not quite it, since neither have Jerkass tendencies, and it was her attempt to befriend him that got him to notice her attractiveness. Plus, the real reason she did so is because she recognized him from their childhood.
Made of Iron: Basically his only specialty. He can take a beatdown like no other.
Gradually moves away from this later on by showing his development, when Kenichi begins to show a physique just as ripped, if not more so, than most of his generation of fighters.
Kenichi indeed gets extremely muscular: he's just still rather short. Compare to Edward Elric of Full Metal Alchemist.
It is stated in the anime that Akisame's training alters the slow twitch/fast twitch muscle ratio in Kenichi's body, creating a lean look, with very strong muscles.
Nice Guy: Would MUCH prefer reading and tending flowers than what he's called upon almost daily to do.
Not So Weak: One of the earlier thugs that beat him down got grabbed on the ankle before kicking him off. The thug then pulled up his pant-leg, revealing a bruise in the shape of Kenichi's hand. Kenichi has since grown much, much stronger.
Terror Hero: Type 5, thanks largely to Niijima. Falls into this trope in episode 24 of Season 1 when some thugs try to bully the drama club into giving up their large room so they can use it for their club. After Kenichi saves the drama club president and announces who he is, the thug's minions begin worry about his presence and exaggerate his reputation a bit, such as being able to take on a bear. However, it's enough to make them run away.
Happens again when he, Takeda, and Ukita save the Shinpaku Alliance members from the rank and file Ragnarok thugs. Niijima once again greatly exaggerates what Kenichi actually did, and causes the remaining thugs to run away due to his power.
Took a Level in Badass: Took hundreds. A few volumes, and he can drop his former tormentors. A few arcs, and he's accidentally hospitalizing them by the dozen. All thanks to the sheer fortitude to survive Ryozanpaku.
To put things into perspective. At the start of the series he was terrified stiff of guys with small knives. Or just guys who wanted to beat him up. Now he can even take on guys armed with huge swords and firearms.
Training from Hell: Driving Kenichi into the ground and scaring his reflexes into gold are standard for the masters of Ryouzanpaku, but the most hellish comes from Koetsuji, who builds simple and complex machines to wring the skill from his disciple's bones. Some intrinsic consequences from failing these machines include (but are not limited to only): burning alive, electrocution, being trapped for hours in one position, and impalement. If they didn't know what they were doing (or if Apachai hadn't learned to hold back), he would be long gone by now. Since they do, Kenichi can actually consider it "training" and gain immense results...though he did actually die once or twice. Good thing two of his masters are also medical geniuses.
Kenichi grows to like it, going so far as to increase his regimen while his masters are absent in Chapter 423. Try to imagine the Kenichi from 200 chapters ago doing that.
Unskilled, but Strong: Kenichi's earlier battles were based more on getting a single hit on his foes, that his inhuman strength gained from training at Ryōzanpaku would turn into a devastating, one-hit KO, than actual combat ability. Akisame even addresses this shortly after Kenichi starts learning actual techniques.
A 16-year-old girl who attends the same school as Kenichi and is currently in her second year. She is the granddaughter of Hayato Fūrinji, the leader of Ryōzanpaku Dojo. Despite being attractive, smart, athletic, and kind, Miu is very socially inept, to the point of having no friends before meeting Kenichi and practically no social life. Miu's social ineptness stems from her upbringing, during which she never had any time to make friends, and also from her home life, in which she is practically a live-in maid.Miu has proven herself to be an immensely skilled fighter. While her exact martial arts disciplines have not been stated, she has shown knowledge of several styles. Her fighting style is graceful and fluid, taking advantage of her agility, coordination, and flexibility, and makes heavy use of kicks. Her skills have been honed to the point where she will reflexively throw anyone who sneaks up behind her.
Battle Couple: With Kenichi, sort of. She started out protecting or looking out for him since she was much stronger in the beginning. Played straighter when he improved enough to be equal to her level, or close to it.
Clothing Damage: Often, sometimes turned Up to Eleven; when she attacks Silkwat and he counters her attacks before knocking her out, that skin-tight fighting costume of hers is so shredded that she might as well be naked. She must paint her underwear zones with spirit gum before putting it on—there's no other logical way enough bits of it could stay on sometimes!
So often in fact that whenever Kenichi imagines them in danger, he automatically pictures her that way.
Glass Cannon: While she's an exceptional martial artist and exceptionally hard to hit or even touch, she rarely can take more than a few hits before collapsing/ being unable to continue. This is played up in the anime so she won't join in a fight she could very easily win, but Kenichi would struggle with.
Instant Expert: Miu can master techniques, training, and even whole styles in a very little amount of time, around a week. Which was made more clear when explained that Miu is the descendant of a tribe of people who specifically breed to create powerful offspring with exceptional martial arts talent. Not to mention her father is the son of the World's Strongest Man, as well as one of the most powerful martial artists in the series
She also learned a workable amount of a new language in the same week.
Male Gaze: Close ups of her chest and butt are a must.
Martial Pacifist: Only fights for others and then will try to end it with the least damage to both her and her opponent.
Meaningful Name: Her name means "beautiful wings" or "beautiful feathers". And as mentioned under Bilingual Bonus, Bulu Indah means "beautiful feather" in Malay/Indonesian.
Ms. Fanservice: Bordering on outright hentai sometimes, particularly in ch. 445-447, on the tail end of Sakaki & Hongou's fight. And that's after several chapters of egregious Male Gaze on her spandex-clad body.
So Beautiful, It's a Curse: She is so beautiful that she had some social problems at her last school because of it (implied to be other girls bullying her). To that end, in her current school she puts on glasses and wears her hair in braids to make herself look plainer.
Team Mom: Runs the dojo with a kind smile... most of the time.
Took a Level in Badass: Just when Kenichi had finally caught up in fighting and even surpassed her in Ki abilities. Silkwat Junazard kidnaps her and trains her in Silat which then causes her to have to begin training her Dou ki something her grandfather was hesitant to start do to the risk. She is now back to effortlessly curb stomping Kenichi.
After the introduction of Rimi, Miu finally gets an enemy that pushes her to her limits, and it's during their final fight that Miu masters her Dou Ki.
Weak, but Skilled: Her fighting style is based on speed, grace and coordination rather than pure strength. All these combined with her vast experience make her one of the, if not the, best desciple level fighter(s)
That said she is still much stronger than she looks.
Wouldn't Hurt a Child: It's how the reader is shown that she's not quite under Silkwat's control. Is also very reluctant to fight with Chikage.
Yamato Nadeshiko: She does clean and cook for the dojo, in fact, the grand master even mention that they wouldn't live so good without Miu care.
Voiced by: Hiroshi Arikawa (JP, TV anime), Yuzuru Fujimoto (JP, OVA), R. Bruce Elliot (EN)
Miu's grandfather and the undefeated elder of the Ryōzanpaku Dojo. He is very tall, very muscular and possesses tremendous vitality despite his advanced age. Hayato is a kind old man but still possesses a reckless streak and can be very arrogant, the former of which is shown by his tendency to spend the dojo's money and to get carried away whenever he has a chance to showcase his strength.Hayato is considered by many to be the most powerful man alive. Even when he uses only 0.0002% of his power, keeps his eyes closed, and splits his concentration and body movements, Akisame comments that he still is the most powerful man in the world.
Charles Atlas Superpower: Even disciples can pull superhuman feats. But Hayato? This old man can run on water, throw bombs huger than he is high into the air, and move so fast a camera slowed down too 1/1000 can barely see a blur of him!
To put that's nearly mach 30! And he wasn't even trying.
One-Man Army: Hell, he is a MONSTER, he fought alone with an entire American military base and WON!
And throwing more people or heavy artillery at him is a bad idea, since he can use people as freakin' shurikens, and has special moves that he uses specifically to take out TANKS!!!
Overprotective Grandad: Comes with a Crowning Moment of Funny in Chapter 423 where Miu has acknowledged Kenichi's feelings and given him a kiss on the cheek...only for the Elder to show up at the front gate, expelling massive quantities of killing intent (so much that Kensei complains that he'll break the doors with his blood lust), and all five of Ryozanpaku's masters desperately trying to hold him back.
Ever since Chapter 423, he's pretty much commanded Apachai and Shigure to "discreetly" chaperone Kenichi and Miu, for their protection (and to make sure Kenichi keeps it platonic).
A 38-year-old philosophical Jujitsu master who was the first master willing to train Kenichi. He is an old friend of Miu's father, Saiga. Despite his seemingly small physique, he is known for having muscles built to perfection. He also has very good insight, often knowing if people are troubled or hiding something; he sometimes even knows what a person is thinking, which scares Kenichi.
The Ace: Not only is he a Martial Arts Master, but he's also considered a genius in multiple academic fields, can bring people back to life with his medical knowledge, is said to have "the perfect body", is always calm and composed, is the main breadwinner of the group, manages to turn a group of school children into emotionless fighting machines in an afternoon, and can outsmart any of the other masters (Kensei spent YEARS using a false Rock-Paper-Scissors pattern until he really needed to win, and Akisame saw through it immediately). If there is something he isn't good at, he'll learn it almost instantly. If that doesn't happen, he learns instantly by watching somebody else do the same.
The "perfect body" part is actually achieved through intense training. Whether that adds to the trope is up to the reader.
Badass Mustache: He actually argues about whether or not it is with James Shiba.
Beware the Nice Ones: He's one of the more cultured and approachable Ryozanpaku masters, and can usually keep his cool in stressful situations. If you do anything that could potentially harm Kenichi or any innocent bystanders, though, he'll show you no mercy.
Cruel Mercy: As all Ryozanpaku Masters he won't kill his opponent no matter the circumstances. Some of the stuff he does to his opponents however. Really it would be Mercy Kill to kill those poor souls.
Prophet Eyes: Subverted in that Akisame is clearly not blind (or if he is, it would come off as a major asspull at this point).
The Reliable One: There is a reason why he was chosen to be Kenichi's primary trainer. Always cool and collected, rather serious, a good organizer, and possesses the best technological and medical knowledge of all Ryozanpaku masters. Compared to him, Hayato (the eldest and strongest and the owner of the dojo) sometimes looks like a mischievous teenager.
A 29-year-old master of karate who claims to hold 100 dan. Sakaki is a very intimidating person even when he tries not to be, something that he does not seem to realize and is put off by whenever someone points it out. He has a kind and caring nature and is a very bad liar, which is shown when Akisame asks why he suddenly decided to teach Kenichi a fighting technique, and Sakaki replied that it was the anniversary of the creation of judo.He is an incredibly powerful martial artist. He his well-versed in multiple forms of karate and possess superhuman abilities, most evident in the fact that he can survive a fall from one of the top floors of a tall building without any noticeable injury.
Anti-Hero: Sakaki tries to give a hard cynical impression, but he isn't fooling anybody, as people he meets keep being amazed at and telling him what a nice and Wise Beyond His Years fellow that he is. The "worst" that he ever does is drag along Apachai on harebrained Get Rich Quick Schemes, and although he worked as a mercenary for a while he never liked it, or accepted immoral missions, and when his old partners did, he immediately turned on them. He mostly earns a living by catching career killers for Interpol and similar.
Badass Biker: When he uses his motorcycle, he definitely counts.
Bruiser with a Soft Center: Is pretty much the biggest softie of the masters. Most of his character's humor comes from his (increasingly desperate) assurances that this isn't the case.
The Cape: Honorable, kind, refuses to kill and is ready to do what is right to help defend the defenseless no matter what. There is a reason why the Trope beneath happened.
Dark Is Not Evil: He's a Dou-style user and very vicious in combat (in fact, the karate school he uses is an art developed and used by YAMI), but he's probably the nicest member of the Ryozanpaku dojo.
Defector from Decadence: It was revealed in Chapter 439 that he was actually groomed by his master to be a powerful follower (and possibly eventual Fist) of YAMI, but he rejected the philosophy of Satsujiken in response to the death of Suzuki.
Jerk with a Heart of Gold: So much so that some have wondered just how much of his image and habits are genuine or are carefully cultivated so as to appear from looking too kind and soft.
Hypocritical Humor: In chapter 422 he shared with Kenichi some tips for fighting when you're wounded: don't let your opponent know you're hurt, avoid unnecessarily large movements, and don't let rage overtake you. Guesswhathedoes.
Gets another moment in chapter 434 when Kenichi and Miu follow him against his wishes, he exasperatedly wonders who taught Kenichi to so flagrantly disregard his masters wishes. Cue placard of him acting in the exact same manner towards his master.
No-Holds-Barred Beatdown: Seriously, had any of his fight hasn't ended like this? He's so brutal Kenichi and Miu took pity on his opponent after he beat him straight through several rooms, walls and all. He also managed to give all of Kenichi's True Companions the shivers (literally) on another occasion...where he claimed to be holding back. And he may actually be telling the truth.
Obviously Evil: He looks like the archetypal bad guy and half of his dialog comes out sounding like a bad guy or The Dragon. Lampshaded by Kenichi when Sakaki promised the Elder to "bring their heads as trophy"; he was joking but still...
Scars Are Forever: Has one across his nose. Chapter 429 hints, and Chapter 431 confirms, that he got it from a fight with Akira Hongo, YAMI's God Fist. In Chapter 443 they gave each other their scars at the same time. Also looks like he's gained a few more during his latest battle with Hongo...which also serve as a Shout-Out.
A 28-year-old master of Muay Thai and is known as the "Death God" of the Muay Thai underworld fighting circuit. Despite this fearsome reputation and his incredible size and strength, Apachai is very kind and gentle. He enjoys playing with children and animals and is very childlike himself. He has a habit of saying the phrase "apa" when he speaks and sometimes yells it while training or fighting.Apachai has been trained in martial arts since he was very young. He is extraordinarily strong, able to shatter stone statues and kick down trees without any apparent difficulty. Despite his incredible size, he is blindingly fast, able to dodge bullets while fighting.
Beware the Nice Ones: One of the genuinely kindest characters in the series. Also one of only two masters known for a fact as capable of giving the Elder a challenge in combat.
Big Eater: If Apachai isn't playing board games with Honoka or berserking at training dummies, he's most likely eating. Given a slightly uncomfortable twist when it's revealed that he was often denied food as punishment or to keep him "on edge" by the man who owned him, before Agaard took charge of him.
A 22-year-old weapons master. Shigure is a very mysterious person. She speaks very little and has a habit of falling asleep on the rafters of the ceiling and also traverses atop them more than she uses the floor. She has little knowledge of most things outside of weapons and has trouble interacting with normal people due to her blunt personality and the fact that she always carries a weapon. She has a pet mouse named Tochūmaru.While the youngest master of Ryozanpaku, Shigure has repeatedly proven herself a formidable person to face. As the successor to the Kōsaka-Style, Shigure has remarkable mastery of all forms of weapon combat, earning her the title of "The Prodigy of Sword and Mistress of all Weaponry". Despite her lithe frame, she is very strong and can cut weapons made of metal to pieces using something with a dull edge, such as a spoon. She once cut a cannon off of a tank and then jammed it through its side.
Cool Big Sis: Not by blood, but tends to act like this to Miu and Kenichi, and by extension, the Shinpaku Alliance.
Case in point, after a bummed out Kenichi is 'banned' from training for a while for daring to take a Weapons Master-class opponent head-on, she has her mouse guide him into the rafters to a listening cup so he can hear what the other masters ''really'' think of his latest display. Cue another When She Smiles moment.
Damsel out of Distress: Gets captured by the Master weapon users of Yami.... and quickly breaks out, several times.
Ninja: Not actually a ninja but she might as well be. Her short kimono & fishnet outfit scream kunoichi, as does her choice of typically ninja weapons (swords, manriki-gusari, shuriken, and kunai) and her habit of setting weapon traps. She also walks on ceilings, but she does this by gripping the beams with her toes rather than magic tricks. Oh, and sneaking in is one of her specialties.
No Name Given: Her father never gave her a name. It was Akisame who gave her the name and he put her in the care of the Kosaka family.
Sacrificed Basic Skill for Awesome Training: She spent her formative years training 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. In the present, Shigure is a formidable weapons master, but has little knowledge of most things outside of weapons, lacks social graces and speaks very slowly.
Shameful Strip: She's captured and stripped by Yami, although they did it because they knew she can even turn clothing into weapons.
Shameless Fanservice Girl: She doesn't seem to mind changing clothes in front of Kenichi and doesn't even bother to lock the door to her room when she changes. However, she is keenly aware of Kensei Ma's lechery and generally foils his attempts to peep at every turn. When she's captured and stripped by Yami, she gets angry and calls them perverts.
The Stoic: Partial subversion. Despite her general lack of expression, her emotions are almost comically obvious.
Sugar and Ice Personality: Icy to nearly everyone, even the other Masters. However, she's a very caring person and shows a warmer side of herself to those who are very close to her like her pet mouse Tochūmaru and eventually Kenichi.
A 41-year-old lecherous master of Chinese Kenpō. Kensei is a sly and perverted man, who tries to take pictures of attractive women, particularly Shigure and Miu. He often sells these pictures to Kenichi in the form of "data books", which usually turn out to be pictures of anything but the two of them. Ma seems to have a plethora of spying equipment at his disposal to aid him in such endeavors. In spite of his perverted and deceptive tendencies, he and Kenichi become quite close, forming a father-son-like bond.Ma is a very experienced martial artist, having been trained since he was very young, and purportedly knows all martial arts indigenous to China. In spite of his size, he is very strong, able to destroy a small bridge with a single kick and to rend the flesh of Diego Carlo, a man said to possess a body hard as steel, with his bare hands. He is very agile, capable of jumping from atop one moving cars to another. Ma is also skilled in the field of medicine; he runs an acupuncture clinic and usually, along with Akisame, mends the wounds of Kenichi and the others.
Badass Normal: He doesn't have any training in martial arts. Even so, he was the only one of his gang to escape Berserker and he did it through sheer agility, speed, and the ability to slip out of his clothes without losing either of the former two.
He also has high-class concealment and evasion techniques that match those of the martial artists. Not to mention he can keep up with most of the Disciple class martial artists in speed, while cackling.
Crazy-Prepared: He has traps around the entire city and Shinpaku's base, and he seems to have a plan any time he has enough time or resources. He even made a back up from the time he helped Akisame download Yami's database, and he is also pen-pals with Inspector Honmaki's daughter, who he made a member of Shinpaku!
Expy: Pointy ears, fangs, beady eyes, big nose and Cheshire cat smile? Check. Jerkass, Magnificent Bastard, and bully? Check. Specialties are information gathering, trickery, and being crazy prepared? Check. May or may not be the devil in human form? Check. Did Hiruma get a haircut or something?
The Friend Nobody Likes: Siegfried's about the only one who genuinely likes him. Everyone else is usually blackmailed into the Shinpaku Alliance, dragged in, or just following another member.
Gonk/Human Aliens: The other characters seem to think he's an alien. The author may clearly agrees with them.
Holy Burns Evil: Can't enter a church or shrine without being carried. Later freaks out when attacked with Vajra.
Hypocritical Humor: Niijima hates people who spread false information. Except when it's him.
Jerk Ass: More or less his defining characteristic.
The So-Called Coward: Niijima is quite cowardly, but when you consider that he's going up against an array of Charles Atlas Superpowered individuals while he himself is physically just a normal person, it makes a bit more sense. That said, Niijima has also never failed to aid Ryouzanpaku when it's something that falls within his area of expertise, even if it's dangerous. As of chapter 556, he's been part of teams that are directly invading enemy military bases.Twice. Simply because his computer skills are necessary. Niijima knows to pick only the battles he can win.
With Friends Like These...: Kenichi pretty much applies this trope to Niijima, who often berated Kenichi early on. But as Kenichi gains power, Niijima starts sucking up to him, and also greatly exaggerates Kenichi's accomplishments, mostly for the former's own selfish gains. He will once in a rare while, however, do some good without any real ulterior motives, such as when he tells Miu that Kenichi missed her play because he was fighting Kisara to prevent her from disrupting the play. He will sometimes also give Kenichi some warnings about threats against him or someone Kenichi may care about.
Boxing Battler: His fighting style, which contrasts with the rest of the cast that primarily uses eastern martial arts.
Can't Catch Up: He sees Kenichi's progress, seeks out a master and is soon almost on the same level.
Conservation of Detail: When he first appears, Takeda stands with a slightly hunched posture. This is actually foreshadowing that the injury that forced him to retire from boxing isn't with his arm, but his spine. Once Akisame fixes him, Takeda is able to stand up straighter.
Heel-Face Turn: He becomes one of Kenichi's closest allies after the latter saves him from a fall during their fight, and especially after Koetsuji fixes his crippled left arm.
I Am Not Left-Handed: Subverted. In his first fight with Kenichi, he starts off by saying that he'll only be using his right arm to fight, instead of using his "legendary left." Turns out that this is actually because his left arm is paralyzed—or it was, until Koetsuji fixed it.
Later is played straight after training with James, who has him wear a harness of some sort; it appears to be made of high-tension springs. When he removes it during the D of D tournament, he lands a One-Hit KO on a guy from a special forces military unit.
Lightning Bruiser: Thanks largely to his training in boxing, Takeda can hit pretty hard and move fast, so long as his legs don't get attacked, or he gets Zerg Rushed.
Determinator: Proves to be one in the D of D tournament, when the Shinpaku Alliance faces the Capoeira Team.
Face of a Thug: When we first saw him, he was positively thugly. Then Art Evolution happened as he became less of a delinquent. The anime took cues from his later appearances and made him that way from the start.
Unskilled, but Strong: And he isn't really that unskilled; he just trains normally, unlike the others, who are either prodigies or have genius masters. Recent events have shown that he could be an absolute BEAST with the right master.
The Worf Effect: Usually the first one down to show the strength of the newest enemy.
Ma Kensei's 16-year-old daughter. She came to Japan in search of her father, who she planned to take back to China. She falls in love with Kenichi.She is able to perceive martial techniques at a level unusual for non-Master-class martial artists.
Absolute Cleavage: Either her outfits will sport this to begin with or a result of clothing damage.
Ascended Extra: While important she doesn't become a regular character until about chapter 310.
Demoted to Extra: Is an important character in the manga and very popular with readers. In the anime, she only appears in two episodes and is never mentioned again. Though this is because the anime ends before Renka really starts to show up.
Then again, with the new OVA series, she may get her animated limelight after all...
Hero of Another Story: Due to being a high ranking member of a large Chinese Kenpo organization, The Phoenix Alliance, she is frequently attacked by members of other opposing organizations, like the White Tiger Black Dragon Clan and even the Chinese Mafia as well as keeping the peace in the Chinese district where she lives. This is hinted at as being Ma Kensei's way of training her.
Attack! Attack! Attack!: Often they will attack anyone they recognize as an enemy of Ragnarok without even bothering to look into the circumstances. This bites all of them in their asses when they decide to attack Shigure.
Jerkasses: In their first appearance, definitely. They brutally beat Kisara for fraternizing with Miu, even though she hadn't just yet planned to betray Ragnarok. Also, their beating of Kenichi was certainly not played for laughs. They seem to have dropped it for the most part after joining Shinpaku, thankfully.
Kick Them While Theyre Down/Kick the Dog: Kisara and Kenichi both received horrible beat downs from them, and they all laughed while they did so. Also, the fan user tried to assault a kitten while it was sick, which thankfully doesn't cross the Moral Event Horizon since no one was crippled or killed.
The Leader: The long haired Tonfa wielder is called this, other then Freya or Niijima, she is the one who gives orders while in the field.
Took a Level in Badass: Shigure notes that they have grown stronger the second time she fights them because while their clothes are destroyed their weapons are not.
Too Dumb to Live: Sure, attacking her the first time was slightly justified since they had no idea who she was (even though Kenichi warned them to run), but the second time they try to fight Shigure around all bets are off.
The Unnamed: To date only one (Hibiki, the chain ball-flail user) has been named.
Dangerous Forbidden Technique: The first to demonstrate the Roar-as-One technique, using explosive ki and contained ki together. It left him confined to a wheel chair, turned his hair white, and gave him one black-sclera'd eye.
The Second Fist of Ragnarok. He rarely speaks and has a calm disposition. Berserker never studied martial arts; he simply has a natural talent for fighting. He is said to be the most fearsome fighter in Ragnarok. However, he is afraid to fight Odin, believing that the latter is much stronger than he is.
Unskilled, but Strong: Subverted, not only is he super strong, but his natural talent for fighting far exceeds everyone elses so much that he does not need to be trained in techniques.
Unstoppable Rage: Practically his fighting style, and thus the codename. The moment before he is defeated in the Ragnarok Arc, he is using his broken, snapped-in-the-wrong-way arm to try and land a blow on Hermit.
The Fourth Fist of Ragnarok. He uses a Karate style that involves using all the joints in the arms. Besides being a powerful fighter, he is also quite intelligent, using information about his opponents to his advantage.
Evil Genius: Seems to consider himself one and his position as the strategist suggests this, but he's not nearly as good as he thinks.
The Starscream: He even builds a team that will comprise the new Eight Fists, himself included. In the end, though, he had about as much success as this trope's namesake. Notably, he didn't see himself as leader, but rather Berserker.
The Fifth Fist of Ragnarok. Niijima described him as a zombie when reporting information to Kenichi, as he had a special ability he called the 'Round Technique', or 'Canon', and it allowed him to take a hit and keep on fighting.
Anti-Villain: Was on the side of the villains, but he never did any harm to anyone.
Bunny-Ears Lawyer: He travelled to Tibet to find a master, and he did—in the form of a prayer wheel.
Let's Get Dangerous: At first you could think that he's plain crazy. After a second thought... he's still crazy. But in combat, he's one of the most powerful members of Shinpaku Alliance. Even the Ryōzanpaku Masters compliment his abilities and skill in his signature technique.
Musical Assassin: Though not necessarily one, he will kick your ass while singing and composing.
Make Me Wanna Shout: Not concussive, but definitely powerful enough to knock you out at point-blank, with his head facing backwards.
Nice Hat: Admit it, you wouldn't mind wearing that.
No One Could Survive That: Siegfried's style of fighting is to literally roll with the punches; in his fights he seems to always absorb one's finishing moves with ease and he even uses these skills to survive detaching his parachute at least 5 stories off the ground by falling through tree branches and landing face-first. Even when he can't avoid the impact, he gets up when he really should not.
The Sixth Fist of Ragnarok. He learned martial arts from Sougetsu Ma, Kensei's older brother. He is the president of the drama club at Kenichi's school.
Afraid of Doctors: In his past, his father married a female doctor who promised to tend to his sister's sickness. After the doctor murdered his father, Natsu discovered that the woman had never bothered to tend to the little girl, sprouting a seed for distrust in the boy.
Always Someone Better: While under Sougetsu Ma's brand of training, Hermit always fights someone at least slightly better than him in all aspects. He realizes that this is how Kenichi has grown so much as martial artist, since virtually all of Kenichi's fights have been with superior opponents. It doesn't stop either of them from winning.
Arrogant Kung-Fu Guy: Notably averted. Even though Kenichi was weaker when they first fought, every attack Hermit threw was fully intended to destroy his opponent and he never lets up until it's over.
Pet the Dog: His attitude towards Kenichi's little sister, who reminds him of his own sister.
Slave to PR: He often must restrain himself from smacking Kenichi because he has to maintain his "perfectly nice guy" public image.
Took a Level in Kindness: Becomes nicer after his battle with Kenichi, though Honoka probably has more to do with this then anything else.
Training from Hell: He and Kenichi have this in common. He even notes that his master seemed to enjoy bullying him during his training. A flashback shows Natsu being forced to climb across monkey bars, by his wrists, with weights holding him down over bamboo spears!
The most recent member of Ragnarok to be made a Fist, transforming what had been the "Seven Fists" to the "Eight Fists". She is also noted to rely on growing during tough battles to win, and her style revolves around extremely acrobatic Taekwondo techniques, which she later combines with cat-like movements to make them even more effective.
She grows to tolerate it from Kenichi, however, when he makes it clear that he doesn't consider her weak, but just refuses to hit girls regardless of their level of strength.
A-Cup Angst: Her small breasts are a Berserk Button for her and the reason why she flies into a frenzy to fight Miu having never even seen her before.
Animal Motifs: After her Heel-Face Turn she has a tendency to lapse into cat-like mannerisms and often has a Cat Smile and cat pupils. She even has a catlike variation of Tae Kwon Do called Nya Kwan Do.
Pet The Cat: Feeding a homeless kitten in an alley. This is what changes Kenichi and Miu's opinions of her.
Power Copying: Despite not having a master, she is able to achieve new levels of Badass by copying first Miu's movements, then a cat's. Somehow fitting, as copying the movements of animals is how many martial arts came to be—Tae Kwon Do is said to have been based on the movements of a tiger.
She's Got Legs: Duh. Her fighting style is based on kicks. Not to mention all of the fanservicey shots of Kisara focus primarily on her legs and prominent rear.
Please Put Some Clothes On: He's flustered by walking in on a naked Shigure, and reacts in the classic style: yelping, blushing, turning his back—all while apologizing profusely—and ultimately presenting his own fur-collared vest for the sake of modesty.
Combat Pragmatist: He goes for eye gouges, neck snaps, and attacks to the groin and vitals, as befits an art focused on killing instead of self-defense, but he goes beyond this into...
Dance Battler: Mostly his minions, actually. Pencak Silat was often passed down and hidden through dance.
Dying Moment of Awesome: For all his arrogance, dirty tactics, and just all around being a bastard of the prime sort, his facing an avalanche without fear while yelling "Because I'm a King!" was pretty awesome.
Jerkass: Even his Evil Mentor had to point out to him that he should not behave like a jerk.
Kick the Dog: Tricking Kenichi into hospitalizing the school's karate club, before beating him to the brink of death.
Manipulative Bastard: He prefers getting into his opponent's head rather than just fighting them. As mentioned above, Kokin tricked Kenichi into harming people far weaker than him to make him unsettled. He even casually stated it would be easy to kill everyone in the school.
Also doubly subverted in the tag team match with her mentor. This not only helps her master when it happens to her by distracting Master Ma, but it also fails hard when she tries use this trope against Renka only to get her master hurt when Ma doesn't leer at his own daughter.
Played straight in the latest arc against Renka. She wasn't taken aback by the fact the she was stark naked, but that Nijima, Thor, and the Valkyries saw her use "boring" moves in a fight, and she runs away, feeling ashamed that she failed her Master.
Foreign Fanservice: She does it on purpose. Being attractively exotic and giving the in-universe audience a nice eyeful are top priority. She doesn't have to try very hard, by most standards.
Friendly Enemy: Gets along pretty well with Kenichi and the others ever since Kenichi attempted to help her brother rescue her. She seemed to be flabberghasted at Kenichi telling her he considers her a friend.
Omniglot: In addition to Japanese she also demonstrates her knowledge of French and German
Willfully Weak: As Renka learn during the amusement park battles, Rachel puts all her energy into making her moves flashy. The result of this is that whens she stops showboating her power increases significantly.
Wrestler in All of Us: You know all those 'moves' the adults stopped you from doing before someone got hurt or fatally embarrassed? She makes them work and makes them work well.
Enemy Mine: When he tries to abort the operation intended to kill all of the students on the beach camping trip, the senior lieutenant refuses to obey the order. Boris immediately stops fighting Kenichi and teams up with him instead to combat the "treacherous" soldiers, incidentally saving the students in the process.
Exact Words: Gets better at creatively interpreting his orders to justify what he wants to do.
Pressure Point/People Puppets: If she is in combat with Ukita, she rapidly and repeatedly taps his body and so spurs it to move into a block, throw, or parry, depending on how he is attacked. She does it deliberately without his knowledge and while having a book on her head the hole time.
Sugar and Ice Personality: Towards Kenichi, as a result of Kenichi's efforts to defuse her as a Tyke Bomb, and towards the Katsujinken (Fist of Life/Saving) side in general; she helps them, but only because she "wants to be on the Young Detective Squad".
Seems to be this for Ukita as well, between covertly guiding/teaching him techniques, and doing things like sitting in his lap while reading.
Sweet Tooth: Exposure to sweets also temporarily dissolves her creepiness, since the Dark Side won't give her any. Even in a panel dedicated to her thoughts verging on epiphany, there are "tastes delicious" and "cake".
Counter Attack: His specialty is reactive martial arts and brutal joint locks.
Disability Superpower: He is blind but has perfected his remaining senses to the point that he can read people's movements from sound, vibrations in the ground, the disturbance of the air, and even from somehow sensing the firing of his opponent's nerves.
"I am not strong despite being blind. I am strong because I am blind."
We Have Reserves: He is totally fine with his master's harsh training regime and its tendency to break the students that can't hold up under it, because there's always more replacements where he and they came from.
Anti-Villain: He seems to truly care about Miu's welfare. He also broke a man's arm, then gave him medicine at the same time—to prevent the already-wounded man from trying to attack him. There might more to him being the leader of Yami than meets the eye.
Secondly, to Akisame, as he has demonstrated superb healing skills. He even looks like a blonde version of Akisame, without the moustache.
Not to mention Akisame calls him his best friend, or former best friend anyway.
Thirdly, and a bit more arguably, to Kenichi as well. Not only does he have gauntlets similar to the ones Kenichi has inherited (and Kenichi's gauntlets used to belong to Saiga), he was also more of a lover of nature before his Start of Darkness; which parallels Kenichi's love of flowers.
It could be said that Kenichi embodies what Saiga used to be before his Face-Heel Turn, while Saiga represents what Kenichi could potentially become if he ever pulled a Face-Heel Turn himself.
Lightning Bruiser: How fast is Saiga, you ask? He is about to cover Miu with his coat. Hostile master-class fighters appear. He lets go of the coat. Everyone in the room is instantly curbstomped. Saiga grabs the coat again. The coat hasn't fallen one millimeter from when Saiga let go of it.
Master of Disguise: Was actually John-san throughout the Captured Miu arc. To provide better context, John-san's appearance is as a short, obese man with a bumbling and jolly personality; Saiga is much taller, leaner, more muscular, much more serious, and he was wearinga three-piece suitwith gauntlets and leg guards underneath the John disguise.
Affably Evil: He's pretty polite one moment, then savagely killing someone the next.
Badass: To be expected from a high level Master-class martial artist. His introductory episode has him killing an aggressive bear with his hands. He can crush heads with elbow strikes. Just ask Tanaka.
White Hair, Black Heart: Actually subverted; he is more than willing to kill, but only those who are willing to kill him. He is more than willing to use people in experiments that would result in harm or death, but only if they are willing and even warns of the dangers.
Why Can't I Hate You?: A feeling many of his opponents have voiced. His love for martial arts is 100% genuine.
Would Hit a Girl / Would Harm A Child: Another of those things that should make him a monster, but doesn't, because it shows that he considers everyone and anyone who steps up to fight him as a Worthy Opponent, regardless of age or gender. He even handicaps himself to fight at his opponent's level.
However, when he discovered he'd killed a pregnant woman, he was not happy; the woman may have made the choice to risk her life fighting him, but the baby hadn't.
Abusive Dad: Severed his parental ties with his daughter when she joined Yomi. Beats her if she loses or gets out of line. Secretly a Papa Wolf who held back because her life was spared.
He trained Miu in silat and is the direct cause of her now being able to use Dou ki.
Fair Weather Mentor: Actually averted. While harsh and brutal and with low attention deficit, it shows that he was in fact a very "competent" mentor, very thorough in his teaching and no different that the Ryozanpaku kind, if a little more evil. But don't you dare to disappoint him or soil the Pencak Silat for your petty reasons or he will end you.
Fallen Hero: Helped out his country to break through the UN soldiers, but soon finds that Victory Is Boring... and it gets worse from there.
His epithet, "Demon Fist God," is not the nickname of a man you want to get too close to, either. Literally so as of Chapter 463—Akira Hongo reveals that Junazard took a third option in martial arts and went down the path of "Gedou" (which literally means "path of the demon").
Older Than He Looks: Underneath his mask, his face looks way too young for a guy who fought in a war 23 years ago. Perhaps he exchanges tips with Kushinada. His hands look strangely older and rougher, though.
Red Right Hand: His habit of swallowing bulky pieces of fruit. In one scene he is even shown biting a pineapple together with the skin.
Talking Is a Free Action: But Averting Inaction Sequence. It's pointed out that it's suicidal to do this in a real fight... unless you are a Master, which then becomes basic etiquette in a Death Match. Hongō is just being rude.
Wager Slave: As mentioned in his picture quote he believes that the loser should always obey the winner, thus voluntary going to Big Lock.
Akira Hongo, Sky
Badass: In his fight with Sakaki, he fixed his dislocated finger by using his thigh as anvil... while in the air. And without stopping their Pummel Duel.
Opponent perched several meters above him on a stone tower, looking down at him? He casually sticks his hands in his pockets and slams his feet into the stone, creating footholds, walking up the vertical tower just to tell him face to face: "I'm the one who's going to kill you."
Cycle of Revenge: Tells Radin Tidat Jihan that if he wants to avenge the death of Junazard, he can come challenge Hongo when he's ready.
Determinator: As a flashback in Chapter 474 reveals, he was this even as a young man. On one occasion, he got shot with a semi-automatic weapon while protecting a hostage, was hurt badly enough to warrant being put into surgery, and yet he left the hospital and went to win a karate tournament he'd previously been signed up for—all while still being badly injured, bandaged and bleeding from his wounds.
Even Evil Has Standards: He won't lay a hand on non-combatants. Also, in Chapter 429, he refuses to fight Apachai and Shigure, the former because he's injured from his earlier fight with Agaard, and the latter because she's a woman (despite them attacking him first) which was only an excuse since they were already severely damaged and he was in front of his disciple's resting place.
He was absolutely pissed when Silkwat tricked him into attacking Kenichi while he was unconscious. If he hadn't pulled himself out of the attack at the last second, it would have killed the boy. To follow that up, Silkwat kidnapped Miu when she tried to avenge Kenichi by attacking Hongo. Sakaki, Hongo, and ELDER, are going after the man with a vengeance.
While he follows the path of Satsujinken, he would never follow the path of Gedou.
Forgotten Fallen Friend: Averted. Right up to the present day, the memory of Suzuki Hayime haunts him and Sakaki, motivating them to fight to the bitter end.
Genre Savvy: Upon being defeated by Hongo, Junazard asks to see the face of the man who bested him up close...but Hongo doesn't comply because he realizes it would give the other man ample opportunity to deliver a killing blow to him even in his crippled state. Subverted when it comes out that Junazard implanted a hidden murderous suggestion in Miu's mind for just such an event...then double-subverted when Miu tries to heal Junazard's wound instead of attacking Hongo.
In an earlier scene, Hongo chooses to walk through the jungle to his destination (Junazard's castle, in a strike attack alongside Ryozanpaku) instead of taking a helicopter because he knows the chopper's engine and rotor-blade noise will betray his movements.
Good Powers, Bad People: He is a consummate Sei fighter who uses palm strikes (typically non-killing techniques) to skewer his enemies as if his hands are lances.
Impaled with Extreme Prejudice: Several of his techniques rely on him using stabbing arm-thrusts to deal damage this way. It's also how he defeats Junazard.
Tranquil Fury: When taunted about his disciple's death, he doesn't go berserk, he just gets FASTER and starts going for the kill strikes more often.
Villainous Rescue: Saves Miu and Kenichi from the leader of Yami's chivalrious order and teams up with Sakaki and Hayato against Silkwat.
We Are Struggling Together: He and the other Nine Fists either loathe or just don't care about each other. When trying to fight the Ryozanpakou masters at the same time with the exception of Shigure, they were more ready to kill each other than the enemy.
Would Not Hit a Girl: Averted. While during the brief skirmish with Shigure (one-sided on her part) in Chapter 429, this was his reason, but he didn't hesitate to crush the leader of the chivalrous team for nearly killing both Miu and Kenichi.
Mikumo Kushinada, Water
Absolute Cleavage: Possibly because her breasts are so big that they prevent her robe from closing.
Flash Step: She is fast, even by Ryouzanpaku's standards. She can create semi-solid speed-clones and use them in combat against both Shigure and Sakaki while picking up Chikage from a different rooftop.
Shipper on Deck: Amusingly seems to ship herself and the Elder. In one fourth-wall straining scene, she makes a suggestive comment only for the Elder to dismiss it in such a way to suggest that she was deliberately misleading the readers.
Mikumo: "...Even though we once felt the hot fires blazing between us."
Hayato: "Stop saying misleading things. The things that were burning were forts and tanks!"
Statuesque Stunner: She's tall enough to make Sakaki look short and Chikage look like a baby and shapely enough to make Shigure look underdeveloped. Sakaki is about two meters tall and Shigure has melons the size of actual melons.
Affably Evil: Literally hasn't stopped smiling since his introduction, enjoys spreading random encouragements and praise around anyone nearby, and seems like a generally nice guy except for the whole 'Yami' thing.
Beware the Nice Ones: His disciple Kokin has implied Agaard is far scarier than he seems. He probably isn't called the Demon Emperor of Underground Muay Thai for nothing.
Friend to All Children: Taught children the martial arts back in Thailand, and was quite popular with them. Apachai might even have picked it up from him.
Friendly Enemy: Despite being Apachai's lifelong rival and Evil Counterpart, he seems to have nothing but respect and admiration for Apachai and his skill, and even expressed genuine remorse at the thought of killing him. Confessing this has been pretty much the only time Agaard has stopped smiling.
Hellish Pupils: Upon close inspection seem to be the kanji for fire. Huh...
Pet the Dog: When he saw Kenichi win against Koukin, he congratulated Kenichi on the win and told Koukin there was no shame in his losing to such a skilled opponent. Gets another next chapter when he assists Kenichi with directions when the Weapons Master he faced tries to kill him.
No One Could Survive That: Believed to have died in a fire, though some people do question it, and sure enough he turns out to be alive.
Sibling Yin-Yang: He and Kensei share being two of China's best fighters, but that's about it. Kensei is short and toned, Sougetsu is huge and muscular. Kensei is charismatic and fun, Sougetsu is a loner and scary. Kensei uses martial arts to protect, Sougetsu uses them to destroy.
I Call It Vera: Kenichi's father 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".
Improbable Aiming Skills: Mototsugu gets a pretty damned good shot off by pointing his rifle backwards, underhanded while running in the opposite direction and not looking.
Papa Wolf: Mototsugu. He'd take on all of Ryozanpaku's masters to protect Kenichi from their training, armed with only a riflenote If you don't know why this last bit's significant, the masters are capable of effortlessly destroying TANKS. And he does a pretty good job at it too.
Big Brother Worship: She's extremely protective of Kenichi and initially suspicious of the Ryozanpaku Masters. Later on she's shown to respond nigh-instantly to his commands.
Clingy Jealous Girl: But in a very cute and adorable way. Despite her constantly getting mad at Miu, Miu always gets hit with Cuteness Proximity whenever Honoka is around, or "attacking" her, such as with a plastic mallet.
Hidden Depths: While at first her ability to always beat Apachai at Go seems to be caused by Apachai's childishness, it is later discovered that even Akisame has trouble beating Apachai. We never get to see Honoka go up against the philosophical judo master, however.
Human Shield / Grievous Harm with a Body: Twirls a little girl like a staff in a fight with Sakaki and then later distracts him by throwing her brother out of the moving train car that they're on.
Locomotive Level: Fights Sakaki on a crowded subway/light rail car and both revels in the fact that Sakaki can't go all out with all the potential victims and uses said Innocent Bystanders against him.
The Mole: Seeds one of his agents into his target's staff.
Death Seeker: Ogata calls him out on it. Tanaka isn't truly prepared to kill Ogata, he merely wants to die by Ogata's hands and join his family in the afterlife. He gets his wish.
Fatal Flaw: Revenge. It was called out by the Ryōzanpaku Masters and conformed by the time of his death.
Henpecked Husband: Outright admits he's whipped and sees Kenichi going down the same path. Then again, he's not really speaking to his wife on the phone. His pretending to be a henpecked husband, speaking on the phone to his dead pregnant wife is a coping technique for his tragedy.
Together in Death: Niijima and Renka see Tanaka and his family leave together after Kensei killed him.
Took a Level in Badass: When he fought Kenichi, he's stated to be equal in power; not quite a master, but much stronger than a disciple. Now, he's able to fight on par with Ogata, meaning Kenichi can't be too far behind.
