- Accidental Pervert:
- His sparring partner and one of his masters are tremendously well-endowed. You do the math.
- And then there's some of Ma Kensei's more... unorthodox training.
- 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.
- Babies Ever After: At the end of the manga, we see Kenichi writing the end of his story with a lot of photos in his desk, including one of a little girl who looks just like Miu with Kenichi's hair color.
- 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.
- Battle Couple: He and Miu live together, spar together, fight Ragnarok goons together but are only kinda-sorta together together. They marry in the end.
- Berserk Button: Call him a coward.
- 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.
- Big Brother Instinct: Messing with his little sister is a VERY bad idea. He once jumped off a cliff and wrestled a shark to save her.
- Big Damn Heroes: Has several moments of it throughout the series.
- 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. Though Mubyoshi is just a combination of basic punching techniques.
- Charles Atlas Super Power: As a result of training at Ryōzanpaku, he can drop school bullies with one punch and run through stone walls.
- Childhood Friend Romance: With Miu.
- Clueless Chick Magnet: While his sights are firmly set on Miu, that hasn't stopped him from unknowingly picking up a small harem of interested girls, including Izumi, Renka, Raichi, and possibly even Shigure.
- 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.
- Covert Pervert: He does buy stuff from Kensei.
- 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.
- Declaration of Protection:
- 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.
- Death Is Cheap: He regularly "dies" during training because Apachai has difficulty holding back. Fortunately, Akisame and Kensei are as skilled with medicine as they are with martial arts.Sakaki: Aw man, how many times is this kid gonna die?
- Expecting Someone Taller: No one he fights can believe he's as good as he is because of his looks and general demeanor.
- Giving Up the Ghost: Every occurrence of this in the series comes from him, mostly from his sparring sessions with Apachai.
- 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.
- The Hero: Kenichi is reconstruction of this trope, particularly the shounen fighting hero. He is almost as terrified of his training as he is of the antagonists arrayed against him. Initially all he wants is a well-tended garden, a well-stocked library, and Miu. This (rapidly) expands to include the ability to protect the ones he loves and fight the evils others ignore. Turns out he'll have to defeat a whole gang of Badasses and an Ancient Conspiracy to achieve most of these things, and defeat his master for the other. Good thing he is a hard working and determined young man, whose aforementioned master (or rather, five of them) have every intention of turning him into, well, the mightiest disciple.
- Heroic Build: Slowly gets one over the course of the story, going from scrawny wimp to bodybuilder's dream before he leaves high school!
- 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.
- Kung-Fu Clairvoyance: Courtesy of Seikuken.
- 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.
- Martial Pacifist
- Memento MacGuffin: The Yin Yang badge he carries on the neck of his shirt all the time. It was Miu who traded it for a cat badge with him years ago.
- Muscles Are Meaningless: In the earlier chapters, Akisame's regimen helped Kenichi build strength over bulk, making him a lot stronger without changing his outward appearance much until about halfway into the story where he shifts into:
- Muscles Are Meaningful: He becomes incredibly ripped by the end of the story with a physique most teen bodybuilders would kill for with the strength to match. By the epilogue we only see his bicep, but by this point it's become as large as Sakaki's Apachai's or the Elder's!
- 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.
- Oblivious to Love: Not as of 423. He finally makes his feelings known to Miu, revealing that it's not so much a case of this as it is Single-Target Sexuality.
- Ordinary High-School Student: When fighting Tanimoto, he thinks something along the lines of "My name is Kenichi Shirahama, a normal high-schooler that loves reading books and gardening... so why is it that I'm now fighting on the roof of a speeding bus!?"
- Pointless Bandaid: Chikage tends to call him "Bandaid", because of it.
- 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.
- Thanks for the Mammary: How Kenichi broke Miu out of her Unstoppable Rage. Subverted in Chapter 459 where he tries to pull it off again to Miu to get her out of her Brainwashed and Crazy state, but he still gets a brutal beat down in the end.
- 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 consider it "training" and gain immense results...though he does die several times. 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, which 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.
- Warrior Therapist: His advances in the Sei style have offered him some very telling insights on some of his opponents.
- Will They or Won't They?: With Miu.
- Wouldn't Hit a Girl: This attitude angers several female opponents and wins the affection of some others. He is acutely aware of how stupid this attitude is, and knows that there are several women in the series that could kick his ass even if he was willing to fight back, but he still refuses to hit them on principal.
Miu Fūrinji / Bulu Indah
Voiced by: Tomoko Kawakami (JP, TV anime), Rie Kugimiya (JP, OVA), Carrie Savage (EN), Alondra Hidalgo (LA)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, where she is both maid and book keeper for a bunch of eccentric adults.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.
- Action Girl: She regularly floors groups of mooks. Ragnarok eventually gave up fighting her and instead begged Kenichi to "call off your crazy girlfriend!"
- Action Girlfriend: Kenichi repeatedly vows to protect her, despite the fact that she's still a more skilled fighter than he is. Eventually he comes close and has actively protected her several times when she was sick or disabled. Still, her grandfather won't let him date her unless he can beat him in a fight.
- Babies Ever After: The end of the final chapter reveals she eventually has a daughter with Kenichi.
- Badass Adorable: More so as a child, but she is still pretty adorable as she kicks ass
- Badass Back: Do not approach her from the back or you find out why.
- Badass in Distress: And a victim of Mind Manipulation.
- 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.
- Beauty Mark: She has one under her left eye.
- Betty and Veronica: Betty to Renka's Veronica because she's the Girl Next Door and Team Mom in the dojo.
- Berserker Rage: A result of her not being able to control her immense Dou Ki. This ends when she finally masters her Ki.
- Beware of the Nice Ones: One of the nicest people, but also one of the strongest disciple fighters so making her angry tends to be a bad idea.
- Bilingual Bonus: Bulu Indah means 'Beautiful Feather' in Malay/Indonesian.
- Born Winner: Miu is the descendant of a tribe of people who specifically breed themselves 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.
- Braids of Action: Zigzagged. Initially, she let her hair down before fighting. After Ragnarok, she dons the braids and lets her hair down in school.
- Brainwashed and Crazy: Even after officially breaking free of Junazard's control, she has a hidden amount of blood lust unlocked as a result.
- Childhood Friend Romance: With Kenichi.
- Clingy Jealous Girl: While not 'officially' with Kenichi, she reacts strongly to Renka flirting with him. She also doesn't like it when Kenichi looks at other girls in the nude, accidental or not.
- Clothing Damage: Often.
- 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!
- Whenever Kenichi imagines them in danger, he automatically pictures her that way.
- Clueless Dude Magnet: Besides Kenichi, other guys in the series are interested in her including Takeda, Ryuuto and Sho.
- Cuteness Proximity: To cats or anything cat-like. Including at times Renka, whom people refer to as cat-like.
- D-Cup Distress: Laments her size due to its interference with her martial arts. Probably doesn't help people call her "dairy cow."
- Don't Sneak Up On Me Like That: Don't ever touch her (and certainly don't grab her) from behind, or you will quickly end up on your back.
- Dull Eyes of Unhappiness: After being kidnapped by Silkwat.
- Fanservice Pack: Her boobs and hips grow substantially in a very short time after she starts her second year at school. Handwaved as puberty, when she wonders how much bigger they will get. Then her breasts and hips got smaller right after Apachai's "death" event, the measurements seems to be the same as her early design.
- Feather Motif: Often drawn accompanied by ethereal feathers. See also Meaningful Name below.
- Forgotten First Meeting: She met Kenichi when they were kids. Miu apparently recognized him right away, but didn't feel the need to bring it up when they meet again.
- Form-Fitting Wardrobe: Even her school uniform and a blanket.
- 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.
- Good Eyes, Evil Eyes: Look at her after she goes into Unstoppable Rage and they change into something sinister.
- Hair of Gold, Heart of Gold: Only Kenichi rivals her in kindness.
- Heir to the Dojo: Raised by the leader of Ryozanpaku and trained by him.
- He Is Not My Boyfriend: Oh, no, she doesn't have that kind of feelings for Kenichi. He is just like a little brother, or a dog who lives in her house. Yet will become incredibly jealous the instant another girl announces her affections for him.
- Hero's Muse: Inspired Kenichi to take up Martial Arts.
- Instant Expert: Miu can master techniques, training, and even whole styles in a very little amount of time, around a week. She also learned a workable amount of a new language in the same week.
- Lady of War: Grace and coordination; that's how she fights.
- Light Feminine and Dark Feminine: The light to Renka Ma's dark.
- Little Miss Badass: Routinely beating street thugs at the age of six.
- 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: In the words of a Ragnarok thug "She wears a purple leotard....built like a super model..."
- Nice Girl: Very polite, caring and helpful.
- Oblivious to Love: As of chapter 423, not oblivious. Indeed, she's far more aware of Kenichi's feelings for her than he realized.
- Parental Abandonment: Her mother died and her father is the leader of Yami.
- Purely Aesthetic Glasses: She wears glasses as a way to dim her looks.
- Raised by Grandparents: Her grandfather, specifically due to the aforementioned Parental Abandonment.
- Sensual Spandex: Her fighting uniform. It's ridiculously skintight.
- 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 Chef: She does all the cooking in the dojo.
- 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.
- Vapor Wear:
- It's pretty obvious that she wears nothing under her spandex battle outfit. It's a leotard after all. It would be redundant.
- As Bulu, it doesn't seem as though Miu is wearing anything from the waist down except for those leg bands.
- Verbal Tic: "Desu wa"
- Violently Protective Girlfriend: When Kenchi was still a novice martial artist this was more prominent. In that period, Ma Kensei actually pointed out to her that this was not good, because this deprived Kenichi of gaining combat experience. After Kenichi took enough levels in badass, this became less prominent, but she actually never stopped being protective of him. Note also that her style of fighting is much more aggressive than Kenichi's.
- Weak, but Skilled: Her fighting style is based on speed, grace and coordination rather than pure strength note All these combined with her vast experience make her one of the, if not the, best desciple level fighter(s).
- Will They or Won't They?: With Kenichi. They do. See Childhood Friend Romance above.
- 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 cleans and cooks for the dojo and makes sure it doesn't run out of money. In fact, the grand master mentions that they wouldn't live so well without Miu's care.
Voiced by: Hiroshi Arikawa (JP, TV anime), Yuzuru Fujimoto (JP, OVA), R Bruce Elliott (EN), Jesse Conde (LA)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.
- Awesome by Analysis: He invented a martial technique specialized in this.
- Badass Grandpa: He's Miu's grandfather, the oldest of the masters, and this means he has the most training and experience of all of them.
- Big Good: He has titles like "The Invincible Superman", "He who has no Enemies", and "The Strongest Man in the World", and has earned every one. It's a good thing he's on Kenichi's side.
- Blatant Lies: I AM THE MYSTERIOUS 20 YEAR OLD, GARYUU X!
- 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! That's nearly mach 30 and he wasn't even trying!
- Engagement Challenge: The only way Kenichi can get his consent on dating Miu, is to defeat HIM.
- Form-Fitting Wardrobe: Kimonos don't work like that!
- Heroic Build: Well over 6 feet tall, made of solid muscle, and doesn't look his actually age.
- Impossible Task: When he says that no one can date Miu unless they can defeat him in combat, what he means to say is that he doesn't want anyone dating Miu.
- Large and in Charge: Biggest master in the dojo.
- Loin Cloth: His swimwear.
- My Greatest Failure: Chapter 430 reveals that his inability to prevent Saiga's Face–Heel Turn is this for him.
- Old Master: He's actually taught Kenichi only a few lessons, but each has resulted in monumental improvements. Basically, He's the one who brings together all the stuff the other masters have been pounding into Kenichi on a daily basis.
- 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 Dad: More like selectively protective grandfather. Keeping Miu by his side as he travelled the world battling evil, fine. Sending her out to protect Kenichi, encouraged. But any prospective suitors (i.e. Kenichi) must defeat the Elder first.
- Paper-Thin Disguise: His identity as Ganryu-X is a simple plastic Metal Heroes mask and doing Kamen Rider poses.
- Red Baron: "The Man Without Enemies"
- Walking the Earth: Appears to have done this both in his youth and during Miu's early years. Arguably still doing it given his semi-frequent "walks" that keep him away from Ryozanpaku for days on end.
- World's Strongest Man: Is called as such on several occasions, when he isn't being called the Invincible Superman. Apparently, using 0.0002% of his power and closing his eyes STILL leaves him the "most powerful being on this planet".
- 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.
- Badass Mustache: He 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.
- When he learns that Shigure was captured by YAMI, he very briefly flies into a rage after he tries to calm himself but fails.
- Broken Ace: He's still haunted by his inadvertent part in killing Shigure's father in their mutual past.
- Catch Phrase: "Naive!"
- The Comically Serious: Especially when green peppers are involved.
- 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 is worse. Really it would be Mercy Kill to kill those poor souls.
- Cultured Badass: There's a reason he's called the "Jujitsu Philosopher."
- Does Not Like Spam: Hates green peppers. Doubles as his Weaksauce Weakness. Kenichi and Miu manage to seal him in his room for a few hours by dangling one in the hallway.
- Gadgeteer Genius: Low-level, but he loves to invent new
- Genius Bruiser: So much so that some visitors to the dojo seemed to know of him as a master artist and philosopher instead of a martial arts master.
- It's Personal: Harming any of his True Companions will anger him but when he learned that Shigure (the daughter of an old friend) had been captured by YAMI, he tries to calm himself by writing calligraphy but fails when he crushes the pen in a rage and declares that he'd make YAMI wish that he will kill them by the time it was over.
- Martial Medic: Started out as a notable chiropractor thanks to jujitsu's knowledge of joints & bones, but becomes an Open Heart Dentist by the D of D arc, capable of performing miracles with a borrowed knife, needle & thread, and booze.
- Martial Pacifist: When threatened by a Ragnarok grunt, he politely tried to talk his way out before using him in a Judo demonstration.
- Muscles Are Meaningless: While much slimmer than some of the other masters, he has built his body to perfection via Art Major Biology.
- Prophet Eyes: Downplayedted in that Akisame is clearly not blind but he looks it and the wise conotations are there.
- Take Care of the Kids: Shigure's father asks Akisame this before the latter's untimely death. He of course agrees and leaves her with the Kosaka Clan while he completed his training travels.
- 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.
- Unusual Eyebrows: It's like a lightning symbol drawn sideways.
- Alliterative Name: Shio Sakaki.
- 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.
- Berserk Button: Anybody seriously harming Kenichi. While he can control himself (with difficulty) when its done by another disciple, when its a Master class... all bets are off
- Berserker Tears: He didn't take it well when Hongo killed Suzuki.
- Boisterous Bruiser: Easily the character who does the most shouting in Ryozanpaku.
- Bruiser with a Soft Center: He's 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.
- 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. Guess what he does.
- 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.
- Luminescent Blush: Mostly at being proud of Kenichi and trying hard not to show it.
- 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...
- The Only One Allowed to Defeat You: This seems to be the attitude Sakaki and Akira have towards one another.
- Papa Wolf: To Kenichi.
- The Promise: Earlier in his life, he promised to marry Jennifer Grey. He claimed he was drunk, but she still wants him to make good on that promise.
- 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.
- Sensei for Scoundrels: A lot of his advice is delivered while at least a little drunk. Strangely his best advice, on life in general if not fighting, is when he is drunk, and he won't remember saying it all.
- Shout-Out: See Shirtless Scene above, plus his latest battle with Akira Hongo has left him with a rather familiar-looking set of finger-poke wounds on his chest. His move, Morsasouken-Zuki, oozes Fist of the North Star.
"It's not like I'm helping you. I just felt like standing here for a little while."
- Yes, Sakaki, you want to teach Kenichi, not because you want to, but because it's your birthday. Riiight. In the dub, because it was supposedly the day Judo was created.
- Despite being ENEMIES he is also one for Hongo.
- He's also pretty protective and caring of Miu and his fellow dojo Masters but he refuses to admit to this. Case in point, this line when Appachai is trying to learn to pull his punches; "It's not like I asked for your help because I was worried about him or nothin'...my sake just doesn't taste right unless I can hear his laughter. That's the only reason!"
- Up to Eleven: The 100-dan karate master. Dan rankings don't go above 10 in karate or other Japanese martial arts. He's probably well aware of this, but nobody's brave enough to call him on it.
- The Berserker: When he fights, he basically loses all limits.
- 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.
- Blank White Eyes: Used for both comedy and badassery, which is just about all his appearances. Apachai's face is rarely drawn in full detail.
- Boring but Practical: His finishing moves are APANCH, CHAIKICK, and The Punch You Don't Let Children See.
- Cloudcuckoolander: A somewhat tragic example, as his past has led to him being woefully unprepared for normal life.
- Determinator: Chapter 406: the guy came back from the dead in a way that would put the Terminator to shame and delivered a God-Slaying Punch while being half-dead just to protect his beloved disciple.
- Does Not Know His Own Strength: Has genuinely killed Kenichi once or twice. He usually knows his strength, but can't control it.
- Genius Ditz: He has excellent knowledge when it comes to animals, even though he doesn't know a lot of other things.
- Gentle Giant: When he's not fighting, he's huge, imposing, and ridiculously sweet.
- Idiot Savant: Apachai is a muay thai genius, but he's nearly clueless about most social norms.
- Living Legend: Leaves behind at least two legends of a Gentle Giant that saved the day and then was never heard of again.
- Mundane Made Awesome: He went through a hellish training to learn to hold back while doing housework so Miu could go to the amusement park.
- Normally, I Would Be Dead Now: It was looking pretty grim for a while there, but he did eventually survive his fight with Agaard, thanks to Akisame and Kensei.
- Names to Run Away from Really Fast: Are you really going to pick a fight with a guy called the Death God of the Muay Thai Underworld?
- No Social Skills: Barely functional in a social setting, since his life has been little but fighting.
- Pokémon Speak: Apachai does this when he gets worked up.
- Red Baron: "Grim Reaper of Muay Thai".
- Speaks Fluent Animal: When Nijima goes missing, kidnapped by Ragnarok, Apachai talks to pigeons for information. It works.
- Third-Person Person: Bordering on Pokémon Speak at time.
- Why Did It Have to Be Snakes?: Does not like planes. Guess what he has to ride at one point?
- Absolute Cleavage: She assumes this for the heroic side sometimes.
- Absurd Cutting Power: Doesn't matter if it's a sword she's using or a wooden rice spoon—anything that Shigure can hold will cut.
- Action Girl: She's obviously damn capable with anything even vaguely resembling a weapon.
- Adorkable: Since she's a bit awkward socially, she tends to quietly puff up and congratulate herself when she says something that sounds kind of cool.
- Aloof Dark-Haired Girl: She is tall, beautiful, dark-haired and acts very calm and serious.
- Badass Adorable: Her adorkable moments do nothing to temper her badassness.
- Badass Longcoat: Usually when she's travelling.
- Blade Reflection: Shigure turns the blade reflection to practical use, using it to see what is behind her. Her only blind spot is the part of the blade reflecting her face.
- Bokukko: She uses the masculine pronoun boku to refer to herself.
- Clothing Damage: The cause, and sometimes, the recipient.
- Collector of the Strange: She collects Cool Swords to prevent her father's work from being used for murder.
- 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.
- She makes the Shinpaku Alliance members special chain armor and gauntlets tempered by her family's secret process, rending them impossibly strong and resistant to blades. She stayed up an entire week straight to do this.
- When she finds herself along with Kenichi and Miu surrounded by several Yami Weapon Masters, she holds the line so that the two can escape and is captured as a result.
- Damsel out of Distress: Gets captured by the Master weapon users of Yami.... and quickly breaks out, several times.
- Defrosting Ice Queen: She's the slowest to warm up to Kenichi but eventually she becomes his Cool Big Sis and it's been hinted that she's probably starting to develop a kind of crush on Kenichi.
- Dramatic Ellipsis: When she... talks it's very... SLOW.
- Full-Frontal Assault: Seems perfectly relaxed fighting nude when attacked at an onsen.
- Fundoshi: In her swimwear.
- Implausible Fencing Powers: Almost anytime she pulls out her sword...or wooden spoon. In chapter 412 she was seen carving shapes into a waterfall.
- Improbable Aiming Skills: Possibly her most remarkable skill, Shigure has perfect aim with any tool she handles. Even with frail or dull-edged items, such as a spoon or faulty blade, she can strike without hitting any vital points. With projectiles, she can precisely hit any speeding and squirming target from a considerable distant. At close-range, Shigure strikes can skillfully cut through targets with such precision, the sliced target can momentarily appear unaffected.
- Improvised Weapon: She is already invincible with only a newspaper. Or a wooden spoon. Or a hair ribbon. Or a mouthful of needles. The Yami put her in special restraints—basically embedding her hands and feet in solid masses of a specially fortified resin—because they didn't dare let her get hold of handcuffs.
- Male Gaze: Most chapter cover art that features her, as well as some shots of her in the story, are done with this in mind.
- Martial Pacifist: Most opponents she faces end up losing without significant injury or by simply having their clothes torn (which she often does to Miu and Freya's Valkyries). Even during fights with dangerous opponents like Kagerō Kii and Mildred Lawrence, she will not resort to lethally slicing or slashing the opponent's body, instead opting to using the back of her sword, and in extreme situations, shallowly cutting or attacking an opponent with a weapon to the point that they have small, non-lethal flesh wounds and cuts.
- Mini Dress Of Power: Her kimono is cut as a miniskirt. Somewhat practical, as it gives her more range of movement than a full kimono.
- Ms. Fanservice: She is a beautiful young woman with a slender frame yet remarkably curvaceous-figure and well-endowed breasts. The Fanservice factor is Up to Eleven in the later chapters where she spend most of the time completly naked!.
- Multi-Melee Master: Her nickname is The Prodigy of Sword and Mistress of all Weaponry.
- 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.
- No Social Skills: Initially is introduced as a loner, often avoiding interaction with the other members of Ryōzanpaku (besides occasionally Apachai). With Kenichi's arrival she begins opening up to the others, and even joins them for meals.
- Not Good with People: She seems to get along better with her pet rat than with anyone else.
- The Quiet One: Doesn't talk much.
- Rapunzel Hair: When she lets it down it comes down to her hips.
- 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.
- Sarashi: In her swimwear.
- Sexy Mentor: To Kenichi. Miu has wondered if Shigure sees him as more than her disciple. She has no qualms about being in a state of undress around him since he's not being perverted (on purpose). Out of all the masters, Shigure trains Kenichi the least, yet it is implied she yearns to train him, and is disappointed with Kenichi's reluctance (and fear) to use weaponry but often tries to convince him to train more.
- 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 because the rest of the men know better. 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. She can and will fight in the nude if she has to.
- Sleep Walking: According to Sakaki.
- Slipknot Ponytail: She didn't have a weapon on her.
- The Smurfette Principle: She's the only female Master-class for the Katsujin-ken and the youngest among them.
- 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.
- Talking in Your Sleep: According to Sakaki, her sleep talking is quite scary.
- The Tease: In Kenichi's case. These poses are proof of it.
- Tomboyish Ponytail: She has long waist-length raven hair usually tied back in a high ponytail
- Ultimate Blacksmith: She inherited her father's supreme skill at forging weapons.
- Unusual Eyebrows: They're like...caterpillars...or something.
- Vapor Wear: She never wears a bra. Howewer, when fighting seriously, she dons chain mail and wears a black strap under her breast to kept the chain mail in place.
- Verbal Tic: Has a habit of pausing whenever she...speaks.
- When She Smiles: Maybe a subversion. It's significant when she does, but unless it's meant for Kenichi, it isn't a very pretty smile.
- Zettai Ryouiki: She wears thigh-high socks.
- Bald of Awesome: He's lost his hair on the top of his head. Hence the Nice Hat. Doesn't make him any less capable in combat.
- Crouching Moron, Hidden Badass: He acts the most goofy and affable of all the Ryōzanpaku teachers, but when the chips are down, yoi'll see just why he's called the Master of all Chinese Kenpo.
- Dirty Old Man: He's almost always taking pictures of attractive younger girls. Though he has never actually done anything to say he is unfaithful to his wife.
- Henpecked Husband: Is terrified of his wife.
- Martial Medic: Runs an acupuncture clinic & knows a lot about Chinese herbalism.
- Martial Pacifist: "Why can't the world be more ero and peaceful?" He's also probably the most gentle when training Kenichi.
- Nice Hat: To cover up his bald spot.
- Pintsized Powerhouse: Shortest man in Ryōzanpaku, but still a master martial artist.
- Sensei for Scoundrels: Is often encouraging perverted behavior in Kenichi as a form of training. Rachel Stanley considers him a genius for suggesting ways to grab attention more shamelessly.
- Tiny Guy, Huge Girl: Whenever he's sharing a scene with Shigure. They are often drawn from odd perspectives that emphasize the height difference. (Involving him pointing a camera at her butt.)
- Transliteration Trouble: Many scanlations translate his family name as "Ba," because that's how it's pronounced in Japanese, but it's supposed to be pronounced the Chinese way.
TochūmaruShigure's pet mouse. Tochūmaru is highly intelligent and a skilled fighter in his own right, able to take down (or at least intimidate) normal people.
- Badass Adorable: Tochūmaru seems to have a lot of the same skills Shigure does, just scaled down in power. At the very least, he's able to take down beings much larger than him. Shigure even says that he can handle any cat that tries to eat him.
- Big Eater: Tochūmaru apparently steals food and blames it on Apachai.
- Non-Human Sidekick: To Shigure, although he also sometimes helps Kenichi.
- Stealth Expert: He's basically a mouse with ninja skills. Being small, Tochūmaru can easily sneak into places unnoticed, which comes in handy.
- Action Survivor: His abilities to run, escape, gather info, use traps, use tactics ,and the ability to sense others make him just as dangerous as the other fighters.
- Awesomeness by Analysis: Every time he use one of his Alien powers (don't ask).
- 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. It's a special breathing technique.
- Bizarre Alien Biology: In an omake it was suggested that his heart is hairy.
- 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: The other characters seem to think he's an alien. The author
mayclearly 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.
- Jerkass: More or less his defining characteristic.
- Non-Action Guy: Subverted. He's a coward through and through, but it's virtually a superpower when it comes time to run.
- Red Baron: "The Lord Demon"; only Siegfried calls him that.
- 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.
- Toxic Friend Influence: He's constantly pushing Kenichi into doing selfish things.
- 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.
- Amazon Chaser: After Miu beats him up due to a (sort of) misunderstanding, he says he's fallen in love.
- Battle Aura: Gets really pissed off when he realizes that Kenichi and Miu are the only ones in the dojo. Lampshaded by Tanimoto
- Takeda also gets points for being the first Shinpaku to unlock his ki all on his own, without being overwhelmed by it.
- 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.
- Defeat Means Friendship: After his fight with Kenichi, you can see them supporting each other on their way to Koetsuji's clinic. Saving him from a lethal fall, and arranging for his paralysis cure no doubt endeared him to Kenichi.
- Defector from Decadence: He worked under Kisara, like Ukita, but he quit after Kenichi helped him heal his arm and get back into boxing.
- Extremity Extremist: He's a boxer after all, but he's half-again an extremist in his first appearance, see I Am Not Left-Handed.
- Green-Eyed Monster: Played for Laughs. He gets real jealous at Kenichi and Ukita's growing popularity with girls.
- Handicapped Badass: Before he fights Kenichi.
- 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.
- Oral Fixation: Often, if not always, chews on a stalk of bamboo.
- Perpetual Smiler: Developed into this after his Heel–Face Turn, but remains fourth in frequency after Kajima, Agaard, and Diego, in that order.
- Slipknot Ponytail: Happens during his fight with Lugh at the amusement park.
- Token Good Teammate: When he was part of Ragnarok, he reassured his opponents who lost to him that they did their best and chewed out Ukita whenever he used unfair methods to win.
- Took a Level in Badass: Once he gets training from James Shiba he manages to almost catch up to Kenichi.
- Verbal Tic: Tends to end his sentences with "~ja nai?" or "isn't it?".
- And Zoidberg: Poor Ukita gets ignored for laughs.
- Can't Catch Up: Because unlike everybody else, he trained normally. It is used for his Character Development, though he still can't catch up.
- Chick Magnet: Not only is Kisara Tsundere for him but Freya is quite obviously crushing on him. And now Shiratori is starting to show some interest in him!
- Defector from Decadence: Same case as Takeda, Ukita leaves Ragnarok in his buddy's wake, but he doesn't show it until saving him from taking a beatdown by the rest of Kisara's thugs.
- 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.
- Heel–Face Turn: One of the first examples of the series.
- Let's Get Dangerous: He may be the weakest of the Shinpaku Alliance fighters, but that does not mean he's someone to be trifled with. A Yami weapon-user finds this out the hard way when Ukita saves Chikage by blocking a dagger with his bare hands and throws him to the ground. Chikage was impressed.
- The Load: Was afraid of ending up as this, and currently is. Well, until he saves Chikage from a Yami weapon-user.
- Took A Levelin Dumbass: While never a genius, he had a lot of common sense and knew when he was outmatched early on. After the tournament storyline, Ukita tends to run straightforward at opponents far stronger than himself, and he usually needs to be saved before something bad happens.
- 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. 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.
Voiced by: Mika Kanai (JP), Kate Oxley (EN), Mildred Barrera (LA)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.
- Attention Deficit... Ooh, Shiny!: As we are frequently reminded, Renka has the habit of chasing moving objects.
- Be a Whore to Get Your Man: Definitely "flirtier" and more shameless than Miu.
- Betty and Veronica: Veronica to Miu's Betty.
- Cat Smile: Which results in Miu suffering from Cuteness Proximity. Flat out lapses into fully cat-like behavior when Miu starts treating her like one, with her Expressive Hair acting just like a Cat Girl's ears.
- Even Kisara, who normally reacts with animosity towards well-endowed girls, sees her as a cat and starts waving cat toys around to play with her.
- Cleavage Window: Almost all of her outfits.
- 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...
- Expressive Hair: Causing many people to refer to her as a cat.
- Expy: Of another chinese girl, Shampoo from Ranma ˝. Oddly enough Renka was called "kitty" and even has a tendency to act like a cat, possibly a reference to Shampoo's cat form. The two also compete against the lead females for the attention of the main protagonists.
- Fanservice Pack: The next time people see her in Chapter 309, her breasts are noticeably bigger, and unlike Miu, this was permanent.
- Fight Magnet: More so than even Kenichi, though she does live in a bad part of Chinatown where the Chinese mafia operates.
- Gainaxing: Starts doing this after her Fanservice Pack in ch. 309.
- Green Eyes
- Genki Girl: She is very hyper and strongwilled.
- 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.
- Light Feminine and Dark Feminine: The dark to Miu's light.
- Ms. Fanservice: Just as much if not more than Miu.
- Odango Hair: Sometimes. It does lean towards Horned Hairdo.
- Outright Lie: Often if it'll get Kenichi to spend time with her.
- The Rival: In Love to Miu. In fighting to Rachel.
- Stripperific: She wears...very revealing Chinese dresses.
- Tsundere: At first towards Kenichi, also towards Miu.
- The Ugly Guy's Hot Daughter: While she may not look anything like Kensei now, she does look a lot like his younger self.
ShiratoriIs MUCH later revealed to be a woman.
- Ascended Extra: Initially nothing more than an extra whom Kisara talks to, but much later on suddenly gets an increased role through the Kisara-Ukita-Freya Love Triangle.
- Badass Bystander: Despite not fighting much it's revealed Shiratori is just as good as Kisara.
- Everybody Knew Already: All the girls are surprised to learn the guys didn't know about Shiratori.
The ValkyriesAn all female weapon using group of fighters who follow Freya and whom Kisara was once a part of.
- Amazon Brigade: All female weapon using team.
- Ambiguously Brown: The Metal Fan User, later revealed, thanks to Fanservice, to just be really tan.
- 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.
- Defeat by Modesty: Often subject to this.
- Elite Mooks: A rare Good Guy version, due to them being stronger than average fighters but weaker than the main fighters. Its later revealed they actually get training from a Master.
- Informed Ability: They (including Kisara) claimed to have gotten better after their Humiliation Conga from Shigure, but were all curb stomped effortlessly by Miu. Most likely because they pressed her Berserk Button.
- 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 They're 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.
- Odd Friendship: The team and Thor are on very friendly terms. Justified since they all have the same master, Freya's grandfather, and are frequent sparing partners.
- 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.
The Eight Fists of Ragnarok
Odin AKA Ryūto Asamiya , Flow
- Big Bad: In the anime he's the last guy Kenichi fights. He's also the toughest, and it takes several episodes for Kenichi to finally defeat him.
- Big Bad Friend: Was one of Kenichi's childhood friends.
- Black Eyes of Evil: After being revealed to be a part of Yami.
- Evil Counterpart: Not evil, but Kenichi could have easily turned into Ryuto if he met the wrong master.
- Forgotten Friend, New Foe: He was one of Kenichi's Childhood Friends.
- The Glasses Come Off: He is nearsighted, but once he has seen an opponent's style and rhythm, he can predict their moves and attack with a punch that never misses.
- Handicapped Badass: He's no less dangerous a fighter while in a wheelchair, managing to trap Freya's arms in its wheels.
- Heroic B.S.O.D.: Rimi's apparent death caused him to fall into a Berserker Rage, but afterwards he refuses to leave Rimi's body even when a brick wall is about to fall on him
- Heroic R.R.O.D.: The Roar-as-One technique left him confined to a wheel chair, turned his hair white, and gave him one black-sclera'd eye.
- Kung-Fu Clairvoyance: Courtesy of the Inner Eye.
- Locked into Strangeness: His hair turned white after he used Roar-As-One.
- Prematurely Grey-Haired: As a side effect of using Roar-As-One, Ryūto's hair turned white.
- No Doubt The Years Have Changed Me
- Shout-Out: Ryuto has become like his mythological namesake. He has become crippled and has aged quite a bit after using his Dangerous Forbidden Technique, which mirrors Odin hanging himself upside down on the World Tree.
- The Stoic: Only after his last fight with Kenichi.
- Turns out he is quietly spying on YOMI and Yami.
- Throwing Off the Disability: He can fight at full force using Sei and Dou for 30 seconds.
- Used to Be a Sweet Kid: Used to be even nicer than Kenichi. Then martial arts turned him cold, ruthless, and power hungry.
- White Hair, Black Heart: Has white hair now.
- Yin-Yang Bomb: The first to demonstrate the Roar-as-One technique, using explosive ki and contained ki together.
- You Gotta Have Blue Hair: He has purple hair. Until he used Roar-As-One.
Berserker AKA Shougo Kitsukawa
- Blood Knight: Becomes more so the longer he fights because he isn't used to people lasting very long against him. Only a real challenge gets him going.
- Born Lucky: Able to keep up and surpass other fighters just on instinct alone, with no formal training.
- He's also just plain lucky, winning a card game after the deck was stacked against him.
- Bubblegum Popping: Loves his bubblegum so much that he is often introduced bubblegum first.
- The Gift: So naturally talented at fighting that he rose to the second in command of Ragnarok without ever having had training, relying solely on street fighting tactics.
- Good Old Fisticuffs: No formal training. No need for formal training.
- The Stoic: Most of the time, Berserker is ironically stone-faced, but whenever he gets actually excited about a battle, he shows why he has the code-name.
- Took a Level in Badass: He was already pretty badass, but now he has been confirmed as one of Ogata's disciples. Training from Hell combined with The Gift...
- Unskilled, but Strong: Not only is he super strong, but his natural talent for fighting far exceeds everyone else's so much that he does not need to be trained in techniques. This is emphasized when he joins YOMI, as his master works to have him turn his 'unskilled' methods into his own self-created fighting style.
- 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.
- Villainous Rescue: During the amusement park arc, saves Ryuuto and Rimi from a falling brick wall that was on fire… by punching it.
Freya AKA Kaname Kugatachi
- Alliterative Name: Kaname Kugatachi.
- Amazonian Beauty: The tallest, oldest, and most mature girl of the Shinpaku Alliance. And she's plenty comparable to Miu and Renka in other areas too, in addition to being the most exotic looking.
- Cool Big Sis: The Valkryie sees her as this.
- Eek, a Mouse!!: She freaks out whenever she sees a mouse.
- Heroic Build: Rare female example in the series.
- I Am Not Left-Handed: Turns out she's not entirely defenseless if she doesn't have a weapon—she can simply apply weapon techniques to bare-hand fighting as needed.
- Raised by Grandparents: She lives with her granddad, who is senile. Or so she thinks, as he's a 90+ year old, ass-kicking staff master.
- Scars Are Forever: Has one on her cheek, but it seems to have healed over time. For the most part.
- Simple Staff: Which she can use to casually poke holes in stone. And depending on how she wields it, it can imitate other weapons.
Loki AKA Kyoichi Takame
- 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.
- Goggles Do Nothing: Except hide his eyes.
- Informed Ability: He spends more time scheming and manipulating than living up to his title as the fourth fist.
- Kick the Dog: Kidnapping Kenichi's little sister.
- Heel–Face Turn: Shown to be gathering information for Niijima much later.
- 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.
Siegfried AKA Hibiki Kugenin
- 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.
- Cloudcuckoolander: His logic is not like our Earth logic.
- Counter Attack: His entire self created style is based around counters. Because he can read the rhythm of his opponent's attacks, Siegfried pulls back at the last second, minimizing the damage to negligible levels, and either falls down to get back up, giving the illusion he is immortal, or rolls with the attack to use the force of the opponent to hit them even harder.
- Determinator: Rivals main characters with this! Sieg, with broken ribs tried to swim across a river to help the Shinpaku in a battle.
- He also searched for three days straight with no sleep to find Despair Island and join the fight.
- Hot-Blooded: He gets incredibly fired up about serving his "Demon Lord".
- Implacable Man: His fighting style makes him seem like a zombie who cannot be harmed.
- Leitmotif: The anime gives him Night on Bald Mountain and Dies Irae for leitmotifs, with his "La-La-La" in sync with the music. A lot of other classical music plays in his scenes, as well.
- 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 and destroy eardrums, 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.
- Took a Level in Badass: By spinning around in circles for 40 days non-stop.
- The Lancer: To Niijima. He sees himself as The Dragon, instead.
- Whole Costume Reference: His outfit resembles those of Red Mages in Final Fantasy.
Hermit AKA Natsu Tanimoto, Moon
Voiced by: Ryo Horikawa (JP), Jason Liebrecht (EN, season 1), Eric Vale (EN, season 2), Gabriel Gama (LA)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.
- Badass Long Robe: His fighting uniform.
- Boke and Tsukkomi Routine: The Tsukkomi to Kenichi's Boke.
- Cynicism Catalyst: The death of his sister inspired him to get stronger however he could, becoming quite violent in the process.
- Even the Guys Want Him: Kenichi at times seems this way towards him.
- Evil Cannot Comprehend Good: Back when he was still a member of Ragnarok, he refused to believe that Kenichi's sense of justice was anything other than a facade.
- Heel–Face Revolving Door: Right now he's in both the Shinpaku Alliance and YOMI. Justified, because his master is in Yami.
- Noble Demon: Much like his Master, he does whatever he wants.
- 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!
- Sougetsu even makes Natsu fight against opponents that he knows are slightly superior to his disciple, so that when he wins his improvement shows more quickly.
- Tsundere: A male version. He even does the Luminescent Blush thing.
- Wild Card: He considers himself on anyone's side. He is merely doing what it takes to gain more skill as a martial artist.
Thor AKA Yūma Chiaki
Voiced by: Naomi Kusumi (JP), Bob Carter (EN), César Garduza (LA)The Seventh Fist of Ragnarok. He joined Ragnarok in order to pursue his dream of making his combat-sumo style mainstream.
- Acrofatic: Not necessarily fat, but he fits the bill, being unexpectedly nimble.
- Anti-Villain: He was never a bad guy and only worked with Ragnarok to further promote his dream.
- Berserk Button: Call him fat, I dare you.
- Boisterous Bruiser: "FOR ALL THE BIG-MEN OF THE WORLD!!!"
- Defeat Means Friendship: Pulled a Heel–Face Turn after Kenichi defeated him.
- I Gave My Word: He considers his promises just as important as his pride as a sumo fighter.
- Lightning Bruiser: Much faster than he appears, hits incredibly hard and can take some damage. And then there's his nick/codename...
- Trademark Favorite Food: Chanko, a kind of stew eaten by sumo wrestlers.
- Verbal Tic: In the manga he seems to be fond of saying "Dosukoi" a phrase used primarily by Sumo Wrestlers of all people. Quite fitting really given his style of fighting
Valkyrie AKA: Kisara Nanjō
- 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.
- Awesomeness by Analysis: Part of how she is able to keep up with the other fighters despite not having a Master.
- Berserk Button: Make fun of her chest, or mess with cats, or refuse to fight her because she's a girl.
- Clingy Jealous Girl: To Ukita, funnily enough.
- Extremity Extremist/Kick Chick: Justified, as she practices Tae Kwon Do, a martial art focused on kicking, using arms for defense and preventing opponents from getting too close.
- Fashionable Asymmetry: Her one-legged jeans.
- Pet the Dog: 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.
- Tomboy with a Girly Streak: She's a tomboyish and violent girl who adores cats.
YOMI - Unarmed
Kajima Satomi, Shadow
- Affably Evil: He seems quite chummy and hail-fellow-well-met for someone who is essentially the head student of a school for assassins.
- Armor-Piercing Attack: His Shinogidashi technique is of the One-Hit Kill variety; turning a single punch lethal.
- ArtisticLicenseMartialArts: Satomi has unmistakably performed a Psycho Crusher and an Izuna Drop during his fight with Kenichi. Somewhere out there, a Ninja-based Fighting Game is missing it's main character.
- Dangerous Forbidden Technique: His Shinogidashi technique and variants. Judging from the effect prolonged usage of it has on his body, it might come with a slice of Cast from Hit Points.
- Evil Counterpart: To Kenichi. Like Kenichi, he's a relatively nice guy, was trained by multiple masters (One being a Furinji) and was said to have no talent.
- Ill Boy: When he was a child, he had a disease that would not have allowed him to live beyond age 20. His entering the world of martial arts and subsequent Training from Hell changed that.
- Ninja: Not concerned with stealth, but his master is genuine ninja and his martial arts is Ninjutsu. He does make handseals though.
- 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.
- Telepathy: He's adept at reading his opponents' heart; this lets him trace their lines of thought to the second and constantly beat them at strategy games. Though opponents with strong hearts like Kokin and Hermit can block it.
- A-Cup Angst: As seen when Kisara pointed in out.
- Abusive Parent: She is often beaten up by her father to train her. Except that he is a Papa Wolf all along.
- Innocent Flower Girl: Kenichi says she can't kill him because no one who loves flowers could kill.
- Shadow Archetype: To Renka. Both Chinese. Both kung fu users. Both disciples of their fathers. However the Ma family, except Sougetsu are very high profile in the Chinese martial arts world, while Raichi's family is dirt poor from rural China.
Shō Kanō, Sky
- Arrogant Kung-Fu Guy: He knows multiple disciplines, but its clear he highly prefers the karate techniques of his main master. Even though he was justified in his strength, Sho is immensely arrogant and tends to call anyone other than Miu and himself bugs.
- Authority Equals Asskicking: He's the head of YOMI before his death and he is ridiculously tough.
- Deadly Upgrade: He's learned how to use Roar-as-One very effectively. This is the same technique that put Ryuuto in a wheelchair.
- Evil Counterpart: He's the evil counterpart to Kenichi.
- Fatal Flaw: Even though he was hailed as having the greatest potential among YOMI, three masters disapproved of him. Two of which disliking of how his fighting style had too much emotion.
- Feather Motif: He has a serious obsession with wings and birds.
- It matches his nickname, Suparna, which was a mythological bird said to have gorgeous wings.
- If You're So Evil Squash That Bird: Most of his childhood was like this. At that time it seems successful, but his mentor knew that it is a failure.
- Impaled with Extreme Prejudice: He really favors spear hand techniques and attempts to stab opponents barehanded a lot.
- Posthumous Character
- Why are you just lying down there...Kenichi Shirahama?
- Redemption Equals Death: Redeems himself by saving Miu, but dies thanks to his own actions.
- Stalker with a Crush: To Miu. He watched her for nearly the entire tournament arc from a distance, and even strangled her unconscious to attempt to take her to Yomi with him.
- Superpowerful Genetics: Like Miu, he is a descendant of the Kuremisago clan, a group who specifically breed to create immensely talented children for fighting and martial arts.
- Super Speed: Not like masters, but Sho is ridiculously fast for a disciple level fighter. He routinely takes people out before they can even see him move, and bullet times without much trouble.
Radin Tidat Jihan, King
Voice by: Ryotaro Okiayu (JP)
- Aristocrats Are Evil: He hates commoners and revolutionists.
- Authority Equals Asskicking: The King of Tidat must know martial arts.
- 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.
- Fictional Country: Tidat. It has plenty of Malay influences.
- Fighting Dirty: By having his men knife Kenichi while distracted and ordering them to kill Miu while he's down.
- Freudian Excuse: "If [he wasn't special], the king would just be alone."
- Lonely at the Top: As a child, even during a game where he wanted to play like everyone else, they always bowed down to him. That was when he first realised the difference between commoners and royalty.
- My Master, Right or Wrong: Even after being cast aside by Silkwat, Radin still held respect for him as his mentor.
- Smug Snake: Thanks to his Royal Blood. However...
- Ironic considering his nickname is Nagaraja, the Snake King.
- Sudden Humility: A few weeks or months after trying to hide from his mentor Silkwat.
- You Have Failed Me: He disposes of anyone who has failed him.
Tirawit Kōkin, Flame
- All Girls Want Bad Boys: Popular with girls in high school without even pretending to be nice. (Constrast this with Tanimoto's "Slave to PR" trope!)
- An omake shows he gets a lot of love letters.
- Awesomeness by Analysis: Almost scarily good at analysing people and discerning details just from looks, to the point of resembling Telepathy.
- There is also a scene where Kenichi mockingly calls him "profiler."
- Compensating for Something: Implies this (in a non-subtle way) about the disciples of Yami's weapon masters, simply stating: "People who swing large objects are often compensating for.... other short-comings..."
- Dark-Skinned Blonde: Was revealed as such in a recent color spread.
- Evil Cannot Comprehend Good: Can't understand why Apachai seems excited to fight Agaard, but Kenichi says that its because Apachai wants to show his former Big Brother Mentor how much he has grown.
- Hidden Depths: Near the climax of their rematch, Kenichi asked Kokin why he fights. Kokin doesn't answer, but his eyes momentarily shift to where Agaard had fallen.
- Identical Stranger: He looks like a sith version of Tanimoto.
- 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.
- Not So Stoic: He doesn't take his master falling to Apachai's non-lethal attack very well at all and seemed genuinely upset he seemed hurt.
- Pet the Dog: Coupled with Not So Stoic, he also laughs for the first time in his second fight with Kenichi.
- Villain Respect: He complimented Kenichi after being defeated by him.
Ethan Stanley, Void
- Anti-Villain: He had nothing against Kenichi and wasn't even interested in fighting him. He only did it to save his sister.
- Big Brother Instinct: Fights Kenichi because he hears that Silkwat might teach his disgraced sister (who had recently lost her master), thus preventing her from being treated as expendable by Yami. They're twins, but it still applies.
- Expy: Let's see great build, a Nice Guy unless provoked, and uses Pressure Points in combat? What we need now is a certain scar, using ATATATATATATA and a different hair style, and you have the best Kenshiro clone.
- Face of a Thug: Very intimidating, despite being a Nice Guy and a...
- Lightning Bruiser: Of the big and fast variety.
- Pet the Dog: Protecting Chikage from blackmail by Niijima and repaying the costs of what he broke.
- And despite being Satsujinken, all of the jobs seen taken by Ethan during his Yomi jobs, are protecting other people.
- Pressure Point: Uses them in his fighting style.
- The Quiet One: Ethan usually keeps his silence. It takes him well over fifty chapters after entering Kenichi's school to even speak with him for the first time.
- Real Men Wear Pink: A macho cheerleader!
- Spot of Tea: Drinks Earl Grey, even.
Rachel Stanley, Steel
- Abusive Parents: According to Rachel, fighting back is how she got her start in martial arts.
- Attention Whore: Has gone as far as to claim Kenichi killed someone/did something naughty to her/both at the same time to get everyone's attention.
- Big Sister Instinct: The brief flashback which highlights the Abusive Parents also shows Rachel protecting Ethan.
- Boring Yet Practical: Her fighting style once she gets very serious.
- Clothing Damage: Happens in nearly every battle. If it doesn't occur naturally, she'll make it happen.
- Defeat by Modesty: Subverted. Not only does she have no modesty, but she welcomes Clothing Damage.
- 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. She also uses Spanish phrases here and there. Which makes sense, considering her master is Mexican. And she probably speaks English, considering she's an American.
- Shameless Fanservice Girl: Definitely. She has no problem exposing herself more in order to gain more attention.
- 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.
Boris Ivanov, Ice
- Child Soldier: He also applies this attitude to teachers at school and calls them "instructors".
- 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.
- Lawful Stupid: Orders and rules are absolute to him. More important than honoring a challenge, even.
- Perpetual Frowner: One wonders if his mom ever warned him that his face would freeze that way. His scowl remains in place even when he's diligently performing classroom chores.
- Becomes hilarious during the school sports festival, when Ono-sensei says that she's never seen Boris so happy. He's still scowling.
- Punch Clock Villain: Starts out as this.
- Teacher/Student Romance: His relationship with Kenichi's teacher may be this.
- Undying Loyalty: Even after effectively being fired as a disciple.
Ryūto Asamiya, Flow
Chikage Kushinada, Water
- Badass Adorable: This girl can toss people three times her size with ease. She also loves sweets and even hides a catalog of different cakes and cookies in her room away from her master.
- Child Prodigy: Of both martial arts and standard education.
- Brainwashed and Crazy: Her Master has one of the fellow Fists 'recondition' Chikage to the point that she mercilessly attacks the Shinpaku Alliance members. They all like her so they don't attack but they plead with her to come to her senses. It works and she promptly switches sides.
- Cuteness Proximity: Reverts to little-girl-mode around things that normal little girls enjoy doing.
- A Day in the Limelight: She is prominently featured in Chapter 424.
- Emotionless Girl: At least in front of Mikumo. Or just the side facing Mikumo, which is a feat, considering said Master must have stunning peripheral vision.
- Expy: Might be a coincidence, but... Tamaki? Is that you?
- A Creepy Child with black hair, traditional Japanese clothing, and has lived their whole life thinking they have no purpose other than to do their job and have had to work on suppressing any emotions? Despite this, it's still obvious to see she still has them? Throw in red eyes and... the other thing, and you have a decent clone of Enma Ai.
- Heel Realization: Causes her to break down during the amusement park battles.
- Improbably High I.Q.: Implied to have one.
- Mundane Made Awesome: Eating a cake with all the seriousness, eye-glints, power auras and split panels of combat.
- No Social Skills: Since her master puts so much emphasis on emotionlessness in martial arts and seems to have Chikage slightly brainwashed as well, she doesn't know much about normal everyday things.
- Pint-Sized Powerhouse: Even though her personal style of jujutsu uses absolutely no strength and all technique, she's still can flip grown men on their backs.
- 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.
- Sacrificed Basic Skill for Awesome Training: She's a genius martial artist and student but she didn't even know about 'cake' or even being polite.
- 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, protecting him in fights, 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".
- Token Mini-Moe: The youngest member of YOMI.
- Trickster Mentor: She seems to be teaching Ukita the moves she makes him do while hiding her role.
- Tyke Bomb: Like all of Yomi, but not yet to the extent of the other members.
- Weak, but Skilled: Kushina Style of Jujitsu — zero strength, 100% technique.
Rimi Kokorone, Atalanta
- Did I Just Say That Out Loud? / Saying Too Much: Blurts out her membership in YOMI and several other key things about herself.
- Disney Death: Seemingly dies after overusing Roar-As-One. However she survives thanks to Ogata stopping her Ki.
- Even Evil Has Loved Ones: She's an Evil Counterpart to Kenichi this way - Her main motivation to get stronger is so she can be a worthy girlfriend for Ryuuto.
- Replacement Mooks: First of Ogata's new students to debut.
- Shameless Fanservice Girl: Wears various outfits thinking it will excite people. She seems to think in particular that any male old enough to be he father will appreciate her outfits.
- Stealth Expert: No killing intent or ki to detect her with.
- Super Speed: Fast enough to frisk and bypass Kenichi and his friends without being detected, and initially a bit faster than Miu herself, which surprised her.
- Suspiciously Specific Denial: Part of her Ms. Exposition moments.
- Third-Person Person: She refers to herself in third person.
- Took a Level in Badass: After training with Ogata in the mountains, she developes Dou Ki. Now she can fight on par with Miu!
- Too Dumb to Live: Uses Roar as One to try and defeat Miu, even though she has proof in the form of the guy she wants to impress that using that technique will more than likely cripple, or kill you.
- Awesomeness by Analysis: He's very perceptive and was able to deduce Takeda's former shoulder injury after fighting him for a few quick exchanges.
- Bastard Understudy: He believes Ogata hopes his disciples will one day grow strong enough to kill and replace him. He's fine with this.
- Black Eyes of Evil: His sclera are black, while his Hellish Pupils are white.
- 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."
- Eyes Always Shut: But he looks very creepy when they are open.
- Handicapped Badass: He's 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.
YOMI - Armed
Hyougo, Siegmarigen, Etc.
Yami - Unarmed
Fake Saiga Furinji, Senzui
- Big Bad: The main antagonist of the Yami arc.
- Curb-Stomp Battle: He makes very short work of Hongo and James Shiba.
- Master of Disguise: He manages to make everyone believe to be Saiga Furinji with a clever disguise..
Isshinsai "Kensei" Ogata, Flow
Voiced by : Akio Ohtsuka (JP)
- Affably Evil: He's pretty polite one moment, then savagely killing someone the next.
- Born in the Wrong Century: Let's be honest, his philosophy would be far more in place maybe two or three centuries back, where killing enemies was more accepted.
- Deceptive Disciple: To the Ryouzanpaku masters. The Elder recognized his sinister intentions right away, but Kensei and Akisame trained him for a while before his true nature because apparent.
- Evil Mentor: Seems to be almost a hobby to him as he does it more than the other Yami members. He even has his eye on Kenichi.
- Probably not anymore as of the most recent chapter, as he acknowledges that, for all his admiration of Kenichi's growth, the Satsujinken and Katsujinken users have to walk different paths.
- Karma Houdini: Despite having conducted dangerous "experiments" on his disciples, despite having killed Tanaka's wife, master, and Tanaka himself, despite having played a major role in nearly kicking off a world war... at the end of the manga, he has not received a single defeat and is still alive and well.
- Knight of Cerebus: His appearance during the Titan Arc reveals that he Killed Tanaka's wife shortly after killing his master, and that she was pregnant with Tanaka's child. At the end of the Arc Tanaka is killed, in front of Kenichi and marking the first onscreen murder of an unambiguous good guy by a member of Yami.
- Mad Scientist: Sort of. He is quite open to "experimenting" on his disciples and even his peers, especially with the Dou-Sei combination technique, which destroys the mind and body of the user.
- Names to Run Away from Really Fast: Strangely averted. Despite being a killer, he's called the Sage Fist.
- Nice Guy: Originally portrayed as one. And still, while he's certainly evil, Takeda still notes that there's an aura around him he can't bring himself to hate.
- Pet the Dog: He genuinely acknowledges Kenichi's thanks to him.You've grown well, boy!
- While he shows no remorse killing martial artists, he carves statues, like Akisame, to cope with the fact he unknowingly killed Tanaka's unborn child.
- He ultimately stops Rimi's body from self-destructing at the last moment and lets her and Ryuuto leave YOMI in peace.
- Razor-Sharp Hand: He is capable of piercing hands with his fingers.
- Strike Me Down with All of Your Hatred: Attempts to pull this on Tanaka. It didn't work, as Ogata overpowered and killed him.
- The Unfettered: Believes the truest purpose of martial arts is to destroy one's opponent, and that using martial arts to protect others is weak and dirtying its original intent.
- Villain Has a Point: While his speech after Rimi passes out is more to show how much he only cares about his experiments in martial arts, he is completely right in that many martial artists often died in trying to perfect their art. He saves Rimi anyway.
- 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 Parent: Severed his parental ties with his daughter when she joined Yomi. Beats her if she loses or gets out of line. Except that he is actually a Papa Wolf who held back because her life was spared.
- Huge Guy, Tiny Girl: Him and his daughter.
- There Was a Door: Headbutts his way through a wall to get past a locked door.
Alexander Gaidar, Ice
- Black Eyes of Evil: He has black eyes and is a villain.
- Does Not Like Guns: Which is ironic considering he is a colonel in the Russian military.
- Dude Looks Like a Lady: Somewhat feminine-looking, but he is still noticeably male.
- Evil Counterpart: To Akisame, right down to artistic talent.
- Eviler Than Thou: He's willing to kill civilians, and not just other martial artists. And he proved it by killing a whole room of Russian politicians.
- Hair-Trigger Temper: He flies into rages pretty easily, so he tries to keep his anger in check by making statues.
- Kick the Dog: Ordering Kenichi's class killed, which borders on Moral Event Horizon, but thankfully the soldiers sent to do so are defeated.
- Know When to Fold 'Em: He is perfectly willingly to withdraw from a fight if he needs to.
- Mother Russia Makes You Strong
- Muscles Are Meaningless: Slim as Akisame, but we don't see whether or not he has the same kind of developed muscles as him, and he is still incredibly strong.
- Personof Mass Destruction: Destroyed an entire battalion on his own because he was in a rage. They don't call him the Fist of Destruction for nothing.
- Pet the Dog: Seems to truly care for Boris. Literally the only time he has ever been shown without a focused lack of expression or face of fury, is when talking to Boris.
Silkwat Junazard, Yudis, King
- Badass Boast:Silkwat: So what? If you are a King, then I am a GOD.
- Blood Knight: So much so that he'll do whatever it takes to keep Tidat Kingdom a war-torn hellhole just so he can make good use of his martial arts ability.
- Combat Pragmatist: His fighting style is incredibly versatile and goes for vital hits.
- It's the only way a death match against one of the Nine should be done.
- The Ditz: Seriously, you find birds with a greater attention span than Silkwat. Also, he seems to have an embittered feud with kitchen utensils and plates.
- Didn't Think This Through: To the point of becoming his defining characterization. In kidnapping Miu for his attempt to obtain a disciple, he gets Sakaki, Hongo, AND Hayato PISSED. And Saiga.
- Evil Cannot Comprehend Good: Was bewildered that Miu tried to heal his mortal wound even in a state of mind-controlled bloodlust.
- Evil Mentor: To Radin Tidat Jihan.
- 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.
- Knight of Cerebus: His arc is the most serious so far.
- Make Me Wanna Shout: His debut has him setting off an avalanche by screaming at a mountainside.
- Malevolent Masked Man: Never shown without his stylized monster mask. That is, outside his village.
- Mind Manipulation: Managed to do this to Miu.
- Names to Run Away from Really Fast: His last name means "corpse" in Malay or Indonesian.
- 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").
- Oh Crap!:
- 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.
- According to the databook, he only eats fruit.
- Spirit Advisor: He was called the Guru and apparently he served as an spiritual guide as much as a mentor to Radin... until he crossed the line. In chapter 454 it revealed that he would have probably killed him regardless.
- Surpassed the Teacher: Jenezad actually killed his master in battle. And he praised him, calling him a perfect warrior.
- 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.
- Victory Is Boring: The reason he perpetuated civil war in his own nation.
Diego Carlo, Steel
- Affably Evil: Not like Agaard, but he is one of the most friendly members of Yami.
- Catch Phrase: This is Diego quality!
- Dramatic Unmask: Subverted in the most common way, with a mask under the mask.
- Graceful Loser: He believes the loser of a fight should always obey the winner.
- Masked Luchador: He even likes to Lampshade some aspects of this trope.
- 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
- Berserk Button: Sakaki is the only one who had managed to piss him off by wanting to impose his desires on others. As far as Hongo is concerned, "selfishness" is the greatest crime in the world.
- He really doesn't like anyone speaking badly about Kanou, as Chapter 471 shows.
- Boring but Practical: Since his opponent is so strong and his martial art so complex, he decided to use the most basic Karate katas against him.
- Cross Counter: How he and Sakaki got their respective scars. It's also done in their last fight, Sakaki using Morote Empi Tobi Hizageri with Hongo counter elbow, knocking both of them out cold. Not that this has slowed their fight .
- 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.
- Duel to the Death: His fight with Sakaki, regardless of what Sakaki might believe.
- Enemy Mine: Due to the trope immediately below.
- 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.
- If You're So Evil, Eat This Kitten: The entry to YAMI was to kill the other participants, since there could be only one. Played straight with Sakaki, who refused to kill no matter what and was sickened by the challenge but subverted with Suzuki, who wanted to die in exactly that way. Sakaki was not amused.
- Jerk with a Heart of Gold: As revealed in a flashback about Shou Kanou at the end of the D of D tournament arc.
- Pet the Dog: Kenichi earns a small degree of his respect in Chapter 429 for defending Shou Kanou's earlier sacrifice to save Miu in the D of D tournament.
- He will murder anybody who stands in his way without hesitation, but after the death of his disciple, whom he truly loved, he refuses to let any disciple die on his watch.
- In Chapter 463, he advises Sakaki to go support Kenichi because, to quote him: "I don't want any more disciples to lose their lives.".
- Pointy Ears: He is the only other character to sport this particular inhuman feature along with Niijima and the archer of the armed division, who has parallel twin pupils.
- Power of the God Hand: Akira Hongo of YAMI's One Shadow Nine Fists is known as God Fist.
- Rapid-Fire Fisticuffs: Technically is not this. It only looks like this because they attack so unbelievably fast as to exchange dozens of techniques in a matter of second.
- Razor-Sharp Hand: He is capable of piercing chests with his hands.
- Rival Turned Evil: To Sakaki, judging from Chapter 429.
- Scars Are Forever: Courtesy of Sakaki in Chapter 443 and vice-versa.
- The Only One Allowed to Defeat You: This seems to be the attitude Sakaki and Akira have towards one another.
- 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. He does it again in Chapter 570, this time saving Nijima from Saiga.
- 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.
- Dating Catwoman: It's implied that she and the Elder were once involved. However, the Elder claims her recollection of their last meeting is misleading, since they only fought together once before parting for decades.
- In one of small panels during the last volumes, she meets up with the Elder at a cafe because of a bet they made years ago and she dresses up in a suit for their 'date'. Despite their very opposite ideologies, they are capable of being cordial to each other.
- Evil Mentor: To Chikage Kushinada. To the point that she had her brainwashed to end her conflicted state of mind with wanting to please her master and being with the Shinpaku Alliance.
- 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.
- Greater Scope Villain: Some dialogue from Senzui implies that Mikumo was the one who ultimately started pushing him towards the Eternal Sunset plan.
- Hellish Pupils: Of the horizontal variety.
- Ki Attack: Probably the most direct and blatant example in the series. In chapter 578, she creates a giant double composed from her ki that is visible from miles away and uses it to attack.
- Lady of War: Uses a very elegant and efficient Aikijutsu-like style of fighting.
- Manipulative Bitch: Chapter 484 hints that she may have been the one who pushed Junazard to kidnap and brainwash Miu. She is also the driving force behind the 'Eternal Sunset'.
- Older Than She Looks: Seems to be about as old as Hayato, but according to Silkwat, Kushinada Style slows the aging process to the point that she's physically 20.
- Psychotic Smirk: She usually has an emotionless or frowned face, but when she (rarily) uses this trope, she looks very scary.
- 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.
- Weak, but Skilled: Apparently Kushinada Style involves 0% strength and 100% skill.
Agaard Jum Sai, Flame
- 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.
- Big Brother Mentor: Used to be this to be this to Apachai. Still is, in a way.
- Dark Skinned Red Head: Was revealed as such in a color spread.
- Evil Red Head: Not evil, but on the side of the antagonists.
- 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...
- Magnetic Anti Villain: People are drawn to him. Even rival Yami members feel an instinctive force that compels them to obey him because of his huge charismatic aura. And he does it unintentionally.
- Perpetual Smiler: To rival Laughing Fist Diego.
- 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.
- Pyrrhic Victory: Caused one in a Flash Back, he deliberately lost the title to a challenger only for the said challenger to die in the middle of the ring after his victory.
- Razor-Sharp Hand: Punches Apachai through the chest.
- You Are Already Dead: Pulled this in his youth in a rigged underground fight where Agaard needed to lose or else Apachai would be taken away to the opponent's gym. Agaard "lost," and his opponent dropped dead about twenty seconds later.
Sehrul Rahman, Void
- Beard of Evil: Turns out to be a weakness. Sakaki grabs him by the beard during their fight in the helicopter and begins bouncing him off of the roof, floor and walls.
- Berserk Button: Using someone as a human shield or a blackmail tool, even if said person is an enemy prisoner; for him, that dishonors the way of the Satsujinken. Mikumo got on the wrong end of a palm-attack from him for threatening to kill Shigure in an attempt to make the Ryuzanpakou fighters surrender.
- Cool Old Guy: He's a pretty gentle guy when not fighting. He had no desire to pit his disciple against Kenichi, stopped Chikage from harming herself as punishment for failing her mission, and even wanted to take Rachel under his protection to keep her safe from Jenezad.
- Even Evil Has Standards: He has no problem with killing his opponents or even the horrors that Yami's plan would unleash upon the world. But threatening to kill a prisoner in order to stop one's opponents is taking things too far.
- Make Me Wanna Shout: His screams can induce crippling fear.
- Pressure Point: Uses this to highly lethal effect.
Sougetsu Ma, Moon
- The Alcoholic: Always carrying a gourd of someone alcoholic drink, though he is never seen drunk.
- Hermit even said his tuition fee was cases of expensive drinks.
- The Aloner: He left China because he felt there was never any place for him there.
- Cain and Abel: Kensei's older brother. But when one of his allies demands he seal the deal by finishing off Kensei personally, he attacks his "ally" instead and fights alongside his brother.
- Evil Mentor: Hermit claims Sougetsu is a hard master who enjoyed bullying him during training. However, the two have been shown to get along fairly well on panel.
- Namesto Run Away From Really Fast: He's known as the Fierce Fist God.
- 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.
Yami - Armed
Ganosuke Yokiou, Second Hades
Ganosuke Yokiou is the head of the Hachiou Executioner Blade and by extension the leader of Yami's Armed Division.
- Badass Grandpa: Just like the Elder.
- Charles Atlas Superpower: On par with the Elder.
- Dual Wielding: Wields twin katanas.
- Evil Counterpart: A pretty blatant one to the Elder.
- Face Framed in Shadow: His face is never shown and is always covered by shadows.
- World's Strongest Man: Has the exact same reputation as the Elder.
Rin Tachibana is a member of the Hachiou Executioner Blade of Yami, the older half brother of Kiyoi Kidou, and the "disciple brother" of Shigure Kosaka.
The scythe wielding member of the Hachiou Executioner Blade of Yami.
The bow wielding member of the Hachiou Executioner Blade of Yami.
- Amazonian Beauty: The most muscular female in the series.
- Defeat by Modesty: From Kensei Ma.
- Red Right Hand: Her double pupiled eyes.
- Stripperiffic: She goes into combat with not much more than a bra and thong.
The sword wielding member of the Hachiou Executioner Blade of Yami.
- Ice-Cream Koan: His way of speaking. To the absolute befuddlement of everyone he speaks to.
- The Stoic: His facial expression never changes...until Sougetsu struck him across the face.
- You Fight Like a Cow: When he engages Akisame in combat the two exchange cryptic poetic verses to each other. At first it seems like Akisame understands him...but then reveals that he can't and was just talking nonsense.

- Gun Twirling/Unorthodox Reload: Mototsugu reloads a Winchester rifle one-handed like this.
- Hammy Herald: Motosugu for his guns.ARISE, SEBASTIAN!
- 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 . And he does a pretty good job at it too.
- Reasonable Authority Figure: Saori is often more level-headed than his father.
Voiced by: Tomoe Sakuragawa (JP), Cherami Leigh (EN), Adriana Casas (LA)Kenichi's younger sister, who cares for her brother greatly, often competing with Miu for his attention.
- Annoying Younger Sibling: Subverted in that she doesn't annoy Kenichi as much as she does Tanimoto.
- 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.
- Huge Guy, Tiny Girl: Riding Apachi like a giant robot.
- Morality Pet: To Natsu Tanimoto.
- Replacement Goldfish: To Natsu Tanimoto, reminding him of his dead little sister.
- The Thing That Would Not Leave: Tanimoto's self-proclaimed keeper.
Sakaki's Elder Sister
Don't know her name, so sue.
- Action Girl: According to Sakaki she can take care of herself.
- Can't Catch Up: Despite taking a level in badass, he still can't catch up with Kenichi, who ends having taken many more levels in the meantime.
- Took a Level in Badass: Sadly it's not enough, but he still manages to land a good hit on Kenichi, even if the latter was distracted.
- Bad Guys Do the Dirty Work: Saves Kenichi and Miu from a high level master class weapon user, but only because Shigure paid him with a bar of gold.
- Dude Looks Like a Lady: Nearly into Ambiguous Gender territory.
- Extremity Extremist: A savate master who specializes in kicks.
- 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.

- Monster Sob Story: Pretends to have one, but he's lying because he's actually a...

- No-Holds-Barred Beatdown: Sakaki defeated him by punching and kicking him through no less than 3 rooms.
- Badass Mustache: Competes with Akisame about it.
- Big Damn Heroes: Totally unexpected from him, but he saves Nijima from Saiga
- Curb-Stomp Battle: Saiga (actually Senzui) crushes him without even trying.
- Expressive Hair: Or rather, expressive mustache!
- Handicapped Badass: One of his legs is in bracers. He can still easily knock you out with one blow.
- Jerk with a Heart of Gold: He does everything to deny having one, but it's pretty clear that he has a hidden one.
- Meaningful Name: Since there's no "v" in Japanese, his name could also be read as Shiva, God of Destruction.
- Revenge Before Reason: Subverted in that he's obsessed by revenge against the One Shadow and abandons the rest of his allies during the final battle to get it. However, he determines that the best way to get revenge against Senzui is to ensure that his plan fails by helping Nijima reach the control room to stop the missile launch.
- Badass Normal: Maybe, she is able to block a master class attack, but she's not on Sakaki's level, may be a low class Master

- Foreign Fanservice: She is an American.

- Guns Akimbo: loves to duel wield with a big gun on her back
- Improbable Aiming Skills: Able to fight with guns but not kill by destroying her enemies weapons

- Character Death: He dies after having his skull crushed.
- Crusading Widower: Ogata killed his wife and unborn child, driving Tanaka insane.
- 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.
- It's Personal: Ogata killed his master/father-in-law.
- Knight Errant: Tends to commit random acts of heroism in his search for revenge.

- 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.

Kei Retsumin, the Human Calamity
Assassin for the Black Tiger White Dragon Alliance

- Bunny-Ears Lawyer: Fights with Pisuke, a Myna bird, in a cage on his head.
- Head Pet: Pisuke
- Morality Pet: Subverted. Pisuke isn't a pet. It's there to die to serve as a warning that he's going too fast and risking his health.
- Rapid-Fire Fisticuffs: The basis of his martial art, Honshiken.
- Speed Blitz: His fight is hard for non-master level fighters to even see.
Suzuki HajimeSakaki and Hongo's friend and referee.
- Awesome by Analysis: Becomes a high level fighter just by watching Hongo and Sakai fight.
- Dying as Yourself: Asks to be killed in a duel so as to not die a dishonorable death in a hospital.
- Impaled with Extreme Prejudice: How Hongo kills him.
- Big Damn Hero: He rescues Kenichi and Miu and takes down multiple Master-class opponents, all while the building is burning. He really is the son of The Invincible Superman.
- Occurs again, when he saves Miu from being killed by Senzui.
- Hero with Bad Publicity: Is blamed for the death of his wife due to Senzui that pretends to be him and guide Yami using Saiga appearance as a disguise.
- Lightning Bruiser: How fast is he, you ask? He is about to cover Miu (with a bad case of Clothing Damage) with his coat. Hostile master-class fighters appear. He lets go of the coat. Everyone in the room is instantly curbstomped. he grabs the coat again. The coat hasn't fallen one millimeter from when he let go of it.
- Luke, I Am Your Father: Is really Miu's father.
- Martial Pacifist: Used to be this. Still capable of it where necessary.
- 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 wearing a three-piece suit with gauntlets and leg guards underneath the John disguise.
- Does in again, this time as a government agent, who helps train the Shinpaku Alliance.
- Papa Wolf: He didn't want to interfere in saving Miu, but ultimately Silkwat forced his hand.
- That Man Is Dead: John-san never existed...he was just made up.
- What Happened to the Mouse?: After helping to save the day in the final battle, he essentially vanishes and isn't even mentioned during the final chapter.
