History OneManArmy / Anime

*** Admiral Akainu is the series' ultimate example during the war. Once he'd made up his mind to kill Luffy, not even the combined efforts of Jinbe, Ivankov, Inazuma, Crocodile, Marco, and pretty much every remaining Whitebeard Pirate could do anything more than slow him down. And this is AFTER getting into a one-on-one fight with Whitebeard and living to tell about it. To top it off, not only is he still standing at the end of the war, but shortly thereafter he goes after the Blackbeard Pirates...who promptly get the hell away when they hear that Akainu is in the area.

* Guts from ''Manga/{{Berserk}}'' is called the "Hundred Man Slayer" because he tore apart the good part of an entire company of Blue Whale Knights, which numbered at least a hundred men, singlehandedly. And this is ''before'' he took up his calling as the merciless demonslayer known as the Black Swordsman. Guts, at the time of this writing, has left this title ''far, far behind'' in his personal body count of both men and demons, cementing his status as an all-around badass.

* In ''Anime/Overlord2012'', [[VillainProtagonist Ainz Ooal Gown]] is a level 100 MMORPG character trapped in a world where legendary beings are equivalent to level 30. Now add into the mix his ability to summon Death Knights ([[OneManArmy any of which can overpower an dozens of trained soldiers with ease]]), [[NoSell a skill making him immune to attacks under level 60]] and [[PersonOfMassDestruction spells that can]] [[OneHitKill one shot 200,000 soldiers]].

** Some of Luffy's crewmates are this as well, particularly the other two members of the Monster Trio, Zoro and Sanji. Zoro defeated 100 bounty hunters on Whiskey Peak by himself, while Sanji singlehandedly fought through an entire train of Marines (though faltered when he reached [=CP9=], who are themselves one-man armies). Robin's Devil Fruit powers also make her this, as she can sprout limbs from anywhere and overwhelm scores of people with ease. Brook, who himself has demonstrated talent at taking out large hordes with his swordsmanship skills, is also this against Big Mom's homies, as due to his Devil Fruit power he can overwhelm their weaker souls. And while the other crew members are less well equipped to take on entire armies themselves, they do boast abilities capable of taking on multiple people at once, which Franky's {{Cyborg}} features, Chopper's MultiFormBalance, Nami's Clima-Tact, and Usopp's Pop Greens.

** Boa Hancock's Devil Fruit power makes her an interesting version of this. Since almost everyone is attracted to her, she can use their lust to turn them to stone, and defeated an entire Marine battalion this way within seconds. Even without this power, she's still a formidable match physically, and she has Conqueror's Haki, making her an extremely formidable opponent to the point of her having StoryBreakerPowers if she was more than a supporting character.

** [=CP9=]; they've been trained since childhood to become superhuman assassins. But none fit more than DragonInChief Rob Lucci, the only antagonist who has ever been able to match Luffy's CharlesAtlasSuperpower…and even surpass it. The only thing that made him lose to Luffy was the latter's greater willpower, and their battle took every last ounce of it; when Luffy finally managed to knock Lucci unconscious, he could barely muster the strength to speak.

** Luffy's crew mates. In order of decreasing strength, [[BloodKnight master swordsman]] Zoro[[note]]He took out a hundred bounty hunters in Whiskey Peak on his own. They surrounded him while he was standing on a rooftop, and he disappeared and proceeded to beat the crap out of them shortly after. This was very early in series, and he's gotten vastly stronger since then.[[/note]] and [[ChefOfIron master chef]] Sanji have [[CharlesAtlasSuperpower Charles Atlas Superpowers]], [[MrFixIt master shipwright]] Franky is a {{Cyborg}} that could match the Terminator, [[MusicalAssassin master musician]] Brook is a [[DemBones living skeleton]] that can butcher someone and sheathe his sword [[YouAreAlreadyDead before they even realize that he's attacked them]] (and [[spoiler:after the Time Skip, he can use the [[GhostlyChill chill of the underworld]] in his attacks, and [[MasterOfIllusion hypnotize his enemies with his music]]]]), [[BadassBookworm master archeologist]] Robin has a SelfDuplication-esque power that lets her multiply her physical strength (which isn't much more than that of the average human) almost infinitely, master doctor Chopper has a MultiformBalance that he uses to great effectiveness, and Nami and Usopp, the only two people in the crew who could get away with being called ordinary humans physically (setting aside their superhuman agility and endurance, that is, but [[WorldOfBadass virtually everyone in the series has that]]), are both smart enough to outwit their opponents while using nature as their weapon; master navigator Nami uses a WeatherControlMachine, more often than not resulting in a bad case of ShockAndAwe for her opponents, and master sniper Usopp uses a versatile arsenal of attacks for the first half of the series, and FantasticFlora after two years.

** Generally speaking, the more powerful crews such as Shanks' and Whitebeard's consist of [[UpToEleven an army of One Man Armies]]
** At the time of Dracule "Hawk-Eye" Mihawk's introduction, Gin referenced him as being one man destroying 50 ships. This was not a difficult feat for Mihawk; he just did it because they were there, and he, [[LonelyAtTheTop the world's greatest swordsman, was bored]].

*** Admiral Akainu is the series' penultimate example during the war. Once he'd made up his mind to kill Luffy, not even the combined efforts of Jinbei, Ivankov, Inazuma, Crocodile, Marco, and pretty much every remaining Whitebeard pirate could do anything more than slow him down. And this is AFTER getting into a one-on-one fight with Whitebeard and living to tell about it. To top it off, not only is he still standing at the end of the war, but shortly thereafter he goes after the Blackbeard pirates...who promptly get the hell out of dodge when they hear that Akainu is in the area.
*** Luffy's grandfather Garp asks Fleet Admiral Sengoku himself to hold him back when that happens, or he will kill Akainu, singlehandedly. Sengoku being the only person Garp trusts to be physically capable of holding him back.
** The admiral [[BlindJustice Fujitora]] ([[HandicappedBadass Issho]]) does not disappoint the admiral legacy: he has a Devil Fruit that controls ''[[GravityMaster gravity]]'', which allows him to throw ''[[ColonyDrop meteors]]'' at his enemies. It's also been stated that the other new admiral, Ryokugyu (real name unknown), is in the same league as Fujitora, though as of yet nothing else has been revealed about him…or her. I did say "''nothing'' else".

** Gold Roger is probably the best example of this, as it was once stated by Garp, that he single-handedly defeated the entire army of an unknown country, all because they have insulted his crew. It was stated that only one that could equal him was Whitebeard, and that was back when the latter was in his prime and before [[DentedIron the number of fights he was in took their toll on him]].

** The titan shifters as a whole are all this. [[spoiler: The Female Titan carved her way through most of the Survey corp and beat Levi's handpicked elite squad before losing to Levi himself.]] The Rouge Titan killed over 40 titans in a single battle where most humans struggle to kill one.

* Vash in ''Manga/{{Trigun}}'' is a PersonOfMassDestruction.
%%** Wolfwood.

** The Stern Ritter are capable of fighting captains. As a result, sixteen of them were able to defeat just under three thousand shinigami (there are around six thousand in total) in a matter of minutes, including several captains, and they only took five casualties in return. With the exception of Renji and Rukia post-TrainingFromHell, '''''NO ONE''''' below captain-level strength is able to take these guys on one-on-one, as even captains have major difficulty against them.

* ''VideoGame/InazumaEleven'', [[JerkAss Fudou]] tries to be this during the third season's match with Korea's Red Dragon. The result? He pisses other member off. This happens again with Brazil's captain.

* In ''Manga/ShamanKing'' Hao (Zeke) becomes so powerful with Spirit of Fire that [[spoiler: he destroys an entire naval fleet designed to kill him and a shaman with a spirit stronger than Spirit of Fire.]] Then [[spoiler: he becomes the Shaman King. Instant annihilation if he even looks at you.]]
** Amidamaru also fits. He killed an entire army that came to capture him. Of course, he dies right after.

* All the heroes in ''Anime/DogDays'' fit this, Cinque Izumi, Rebecca Anderson and Nanami Takatsuki. Each of them can take on entire armies of regular soldiers with ease.
** The 2 strongest characters of the series of course can do as well, Brioche and Leonmitchelli, or even better. Leonmitchelli is strong enough that a single attack can defeat multiple soldiers. But she could never defeat Brioche, one of her attacks transforming her sword into a gigantic one.

* Berseker from ''LightNovel/FateZero'' is capable of taking on a barrage of weapons from Gilgamesh without even flinching. He later destroys Gilgamesh's [[CrazyAwesome nuclear-powered Indian airship]] with a [[CrazyAwesome F15 jet fighter]], which has the firepower of an entire armada.
** Gilgamesh himself proves more than a match for an entire army, [[spoiler:when he takes out Iskander's massive army of Heroic Spirits with a single swing of Ea]].
* Maka Albarn from ''Manga/SoulEater'' kicks the shit out of a huge group of thugs who were attacking her partner, Soul, all by herself, in UsefulNotes/{{Italy}} on one instance. Being she's committed to only killing evil humans whose souls are no longer human and have become Kishin eggs, however, she merely leaves them unconscious.
** Black Star is said to do this quite often too.

* Hiraga Saito from the ''LightNovel/TheFamiliarOfZero'' light novel/anime series stopped an army of 70,000 for about two days by targeting the commanders and flustering their movements. His predecessor destroyed an army of 1000.
** In the anime, Derflinger notes that [[{{Tsundere}} this was, ultimately, easier than dealing with Louise]]. This [[spoiler:ended up killing him]]. Essentially, [[BastardGirlfriend Louise]] is more harmful to Saito than [[spoiler:dying a bloody death]]. Let that sink in.

* In ''Manga/DragonBall'', Son Goku defeated the Red Ribbon Army, the strongest army in the world at the time ''by himself''. ''At age 12''. When he told his friends, who had come to back him up the look in their faces was priceless.

** Special mention should go to Dr. Gero's androids; he was the mastermind behind the aforementioned Red Ribbon army, and consequently decided to beat Goku at his own game in retribution: Creating one individual with the power of an entire army. Androids 19 and 20 were formidable fighters even after the Z Fighters' TrainingFromHell in preparation for them, Androids 17 and 18 required the Saiyans to go through even more Training from Hell in order to change which end of the CurbStompBattle they were on, and Android 16 was strong enough to hand 17 and 18 their heads... though he was never an adversary to them, or the Z Fighters for that matter.
*** And, of course, we have Dr. Gero's mightiest android, Cell, crafted with his evil and [[AllYourPowersCombined the Z Fighters' cells]]. His imperfect form is capable of fighting evenly with 16 and can grow stronger with every human he absorbs. His perfect form, meanwhile, is capable of Curb Stomping all of the Z Fighters at once [[spoiler:except Super Saiyan 2 Gohan]], and can [[FromASingleCell regenerate from any injury]], [[spoiler:[[SuicidalCosmicTemperTantrum even his own self-destruction]], [[CameBackStrong and come back even more powerful]].]]

** Kira takes the cake really. While everyone else there (and Kira too at times) still had back up, for the majority of Seed and Destiny Kira was the only active pilot of his team with only their battleship as back up. He still came out on top, even when in Destiny he was fighting two other armies at once.
* And of course, [[AcePilot Amuro Ray]] and [[Anime/MobileSuitGundam the original Gundam]]. [[http://www.nicovideo.jp/watch/sm4926226 Proof here]].
** For those without Nico Nico accounts, the video is of every kill Amuro made in the original series. 142 on-screen kills. And since some of those were Mobile Armors or battleships, the actual number of Zeon soldiers he killed is quite a bit higher. This all took place in a couple of months, remember.
** From the same series, Char Aznable. His claim to fame before appearing on screen? Soloing ''five battleships in a single battle''. He's so good that he didn't take Amuro's ''skills'' (as opposed as his SuperPrototype) seriously until he pulled something similar (namely taking down nine mobile suits and two warships, with three other MS and another cruiser dealing with the ''White Base'', in ''less than three minutes'').

* When the RedshirtArmy gets wiped out by Precia's MechaMooks in the first season of ''Franchise/LyricalNanoha'', Chrono steps up to the plate... and proceeds to mow down Precia's welcoming committee with little effort much to Nanoha's astonishment, then tells Nanoha and her friends to handle the out of control [[MineralMacguffin Jewel Seeds]] while he blazes a trail to [[BigBad Precia]] on his own.
** The other characters eventually gain this trait in later seasons too, soloing waves of {{Mooks}} on their lonesome. For example, Signum once demonstrated her new upgrade by showing up as the only reinforcement against an invading squadron of [[MechaMooks Gadget Drones]], and destroying all fifty of them in one shot.
*** Earlier in the series, Hayate had wiped out four groups of 48 of the same {{Mooks}} with a single spell. With one hand figuratively [[PowerLimiter tied behind her back]].
* ''Manga/{{Vagabond}}'' has "Musashi and the Seventy." The Yoshioka swordsmen are not all FacelessGoons (in fact at least three have full names and a number have internal dialogues), but ''EGAD'' UsefulNotes/MiyamotoMusashi is right up there with Guts; it ends up catapulting him from a local celebrity to a national figure.
** However, the effort seriously weakened Musashi and gave him injuries that are still hurting him in the present. It was more BrokeYourArmPunchingOutCthulhu than OneManArmy.

* ''Manga/{{Saiyuki}}'''s Hakkai killed one thousand demons with nothing but his own hands and a small knife. Unfortunately for him, this led to a KarmicTransformation because "bathing in the blood of a thousand demons" turns you into a demon. Unfortunately for everyone else, this makes him [[SuperpoweredEvilSide a lot more powerful]]. And he's the TeamMom!
** Seiten Taisei (Goku's SuperpoweredEvilSide) and [[{{Tykebomb}} Nataku]] count as well. In the latter's case, Nataku's father considers it an insult that general Kenren's army could substitute for him.

** Main protagonist Monkey D. "[[NiceHat Straw Hat]]" Luffy:

** Followed by the thousands of Marines and agents being decimated. RubberMan plus CharlesAtlasSuperpower equals CurbStompBattle.
** The rest of his crew also falls under this category. In order of decreasing strength, [[BloodKnight master swordsman]] Zoro and [[ChefOfIron master chef]] Sanji have [[CharlesAtlasSuperpower Charles Atlas Superpowers]], [[MrFixIt master shipwright]] Franky is a {{Cyborg}} that could match the Terminator, [[MusicalAssassin master musician]] Brook is a [[DemBones living skeleton]] that can butcher someone and sheathe his sword [[YouAreAlreadyDead before they even realize that he's attacked them]] (and [[spoiler:after the Time Skip, he can use the [[GhostlyChill chill of the underworld]] in his attacks, and [[MasterOfIllusion hypnotize his enemies with his music]]]]), [[BadassBookworm master archeologist]] Robin has a SelfDuplication-esque power that lets her multiply her physical strength (which isn't much more than that of the average human) almost infinitely, master doctor Chopper has a MultiformBalance that he uses to great effectiveness, and Nami and Usopp, the only two people in the crew who could get away with being called ordinary humans physically (setting aside their superhuman agility and endurance, that is, but [[WorldOfBadass virtually everyone in the series has that]]), are both smart enough to outwit their opponents while using nature as their weapon; master navigator Nami uses a WeatherControlMachine, more often than not resulting in a bad case of ShockAndAwe for her opponents, and master sniper Usopp uses a versatile arsenal of attacks for the first half of the series, and [[spoiler:FantasticFlora]] after two years.
*** Zoro took out a hundred bounty hunters in Whiskey Peak on his own. They surrounded him while he was standing on a rooftop, and he disappeared and proceeded to beat the crap out of them shortly after. This was very early in series, and he's gotten vastly stronger since then.
** [=CP9=] also counts; they've been trained since childhood to become superhuman assassins. But none fit more than DragonInChief Rob Lucci, the only antagonist who has ever been able to match Luffy's CharlesAtlasSuperpower…and even surpass it. The only thing that made him lose to Luffy was the latter's greater willpower, and their battle took every last ounce of it; when Luffy finally managed to knock Lucci unconscious, he could barely muster the strength to speak.
** Fisher Tiger also counts, climbing the Red Line and raiding a Marine base by himself. Not to mention freeing all the Celestial Dragons' slaves. Note that the Red Line is ''over 6 miles tall''. So Fisher Tiger climbed a mountain taller than Everest, then immediately took down an entire Marine base (including [[OneHitKill oneshotting]] a Vice Admiral) without taking a moment to rest.

** Capone Bege ate a fruit that made him a fortress for minature armies, when an object or human goes out of the barrier, the object or human expands to normal size. So, he is ''literally'' an one man army.

*** And Luffy's grandfather Garp asks Fleet Admiral Sengoku himself to hold him back when that happens, or he will kill Akainu, singlehandedly. Sengoku being the only person Garp trusts to be physically capable of holding him back.
** And the admiral [[BlindJustice Fujitora]] ([[HandicappedBadass Issho]]) does not disappoint the admiral legacy: he has a Devil Fruit that controls ''[[GravityMaster gravity]]'', which allows him to throw ''[[ColonyDrop meteors]]'' at his enemies. It's also been stated that the other new admiral, Ryokugyu (real name unknown), is in the same league as Fujitora, though as of yet nothing else has been revealed about him…or her. I did say "''nothing'' else".
** The aforementioned "Dark King" Silvers Rayleigh was Gold Roger's second in command. He is seen easily handling an Admiral (Kizaru), and says the only reason he is not also taking down a Pacifista and protecting Luffy's crew simultaneously is because of his age and his lack of action in several years, not to mention he would not call more attention to himself by straight up killing an Admiral.
*** But Gold Roger himself, is probably the best example of this, as it was once stated by Garp, that he single-handedly defeated the entire army of an unknown country, all because they have insulted his crew. It was stated that only one that could equal him was Whitebeard, and that was back when the latter was in his prime and before [[DentedIron the number of fights he was in took their toll on him]].

* ''Webcomic/AxisPowersHetalia'' has the AnthropomorphicPersonification of England vs. America and a whole bunch of soldiers. England still manages to get America at his mercy, [[spoiler:though in the end [[IWantMyBelovedToBeHappy he can't bring himself to shoot]].]]
** It's also interesting that there are moments of allegory in which they literally are a one man army; the most prominent example would be China single-handedly defeating both Japan and Germany with just a wok.
** And then there's Hungary taking out the entire Prussian army by herself. Probably another instance of allegory, but still [[CrowningMomentOfAwesome pretty freaking awesome.]]

** And now Negi is worthy of such title, slaughtering through hundreds if not thousand of shadow demons while barely slowing down. Other members even lampshade it by saying that he doesn't leave any enemies for them to fight.

* In ''Manga/RurouniKenshin'', Kenshin is perfectly capable of taking on numerous mooks and dispatching them with pure speed. He doesn't have the title "Strongest of the Patriots" for nothing. One of his former allies Tani, a corrupt Isshin Shishi states that an entire military unit wouldn't be enough to handle him.
** Also, Sanosuke took out 200 mooks while simply relieving stress, and he's far outclassed by Kenshin.
** Really, most of Kenshin's allies and enemies fall under his trope.
* In ''Manga/FullmetalAlchemist'', King Bradley proves himself to be this during the battle with the Briggs soldiers; for one thing, the guy takes down a ''tank'' by himself.
** With a ''sword'', no less.

** The State Alchemists are viewed as such in-universe. The Ishbal war had been dragging on for years until the State Alchemists were sent in. It ended, quickly, abruptly and messily.
*** And the viewers get to see just why when [[spoiler: Roy takes on [[EldritchAbomination Envy]] in a RoaringRampageOfRevenge. For some perspective, Envy is an AxCrazy shapeshifter, possesses an insane HealingFactor to the point where it's practically immortality, and can transform into a ten-story-tall massive green monster. [[PlayingWithFire Roy]] is [[YouKilledMyFather very]], ''[[ItsPersonal very]]'', '''''[[UnstoppableRage very]]''''' pissed. The battle is completely, utterly one-sided and takes Roy all of some thirty minutes of constant KillItWithFire, with a side of [[EyeScream flash-broiled eyeballs]], to reduce Envy into a pathetic worm-thing.]] Note that it took that long in large part because Roy ''wanted it to be slow''. And turning into that giant monster form proved to be a literally huge mistake, as it just made Envy a bigger target.

* In ''Manga/AhMyGoddess'', Lind the Valkyrie's job description is essentially that of Heaven's own One Woman Army. Belldandy has the skills and potential but not the personality to be the same.
** Satan Hild could potentially qualify, one of her smaller clones that only had a thousandth of her full strength could her its own when Lind attacked her, and she was mostly just defending herself till she convince Lind that WorldGoneMad [[NotMeThisTime wasn't her doing]].

* Gintoki in ''Manga/{{Gintama}}'' can be this when he feels like it, which is pretty much never. It's stated to be one of the reasons no one bothers Otose in Kabukichou. Most people would rather deal with the nose-picking lazy bum living above her shop instead of the ''White Demon.''

* Wolfwood in ''Manga/{{Trigun}}''. Vash is a PersonOfMassDestruction.

** From the same series, Char Aznable. His claim to fame before appearing on screen? Soloing ''five battleships in a single battle''. He's so good that he didn't take Amuro Amuro's ''skills'' (as opposed as his SuperPrototype) seriously until he pulled something similar (namely taking down nine mobile suits and two warships, with three other MS and another cruiser dealing with the ''White Base'', in ''less than three minutes'').

** The 2 strongest characters of the series of course can do as well, Brioche and Leonmitchelli, or even better. Leonmitchelli is strong enough that a single attack can defeat multiple soldiers. But she could never defeat Brioche, one of her attacks transforming her sword into a gigantic one.

* ''Manga/DogSoldier'' has John Fyosuke Hiba, of course (sometimes two-man, with Fudo).

* Futaba from ''Manga/{{Mitsudomoe}}''. Thanks to her, an innocent game of Fruit Basket Turnover becomes SeriousBusiness.

* Any [[YouAreNumberSix single digit]] Claymore from ''Manga/{{Claymore}}'' (duh) can easily exterminate hordes of simple Yomas with little difficulty, let alone Humans (fortunately Claymores have an ironclad rule against harming people). ''Really'' powerful Claymores can even do this to other Claymores, [[spoiler:like when [[RebelLeader Miria]] single-handedly defeated almost every other Claymore in service all by herself and ''without seriously injuring any of them'']]. Although for this example it's more correct to talk about [[WorldOfActionGirls One Woman Armies]].

* Guts from ''Manga/{{Berserk}}'' is called the "Hundred Man Slayer" because he tore apart the good part of an entire company of Blue Whale Knights, which numbered at least a hundred men, singlehandedly. And this is ''before'' he took up his calling as the merciless demonslayer known as the Black Swordsman. Guts, at the time of this writing, has left this title ''far, far behind'' in his personal body count of both men and demons, cementing his status as an all-around {{Badass}}.

** Minato Namikaze, the Fourth Hokage, is the target of a "flee on sight" order from the opposition during the Third Great Ninja war. Later, he takes out an entire force by himself. [[spoiler:He was also the fastest ninja alive, repeatedly facing [[BadAss A]] and Killer B (the 2nd and third fastest ninja alive) multiple times and beating them, even in the first encounter A-at his maximum speed, couldn't touch him]]. Note what that said. It was not a "kill on sight" order like (allegedly) some modern intelligence services have with regard to highly wanted terrorists. '''Flee''' on sight. Minato's mere ''presence'' was enough to send the enemy running. [[spoiler: And now he's [[BackFromTheDead back]]]].

* Girge in ''Manga/BreakBlade''. When you look up OneManArmy in the dictionary, his picture pops up. This guy can single-handedly take out some of the most advanced Golems, fight an elite troop of five and kill every single one of them with a Golem ''that has only one arm and leg left'' and smash the highest ranking soldiers of the enemy nation ''twice'' without breaking a sweat. And that's only [[PunchClockHero nine-to-five stuff.]] His being such a {{Badass}} is the only reason he is allowed on the battlefield because of certain...[[AxCrazy personality]] [[BloodKnight issues]] of his.

* Any [[YouAreNumberSix single digit]] Claymore from ''Manga/{{Claymore}}'' (duh) can easily exterminate hordes of simple Yomas with little difficulty, let alone Humans (fortunately Claymores have an ironclad rule against harming people). ''Really'' powerful Claymores can even do this to other Claymores, [[spoiler:like when [[RebelLeader Miria]] single-handedly defeated almost every other Claymore in service all by herself and ''without seriously injuring any of them'']].

* Due to the immense power of black triggers, their users in ''Manga/WorldTrigger'' become one-man armies. They are expected to fight solo against multiple opponents and win. In particular, Amou's black trigger is capable of demolishing an entire section of the abandoned city infested with enemies, buildings and all, to dust.

* An early chapter of ''Webcomic/OnePunchMan'' has Saitama fight and defeat a massive horde of giant creatures called Subterraneans. This then gets played for laughs after it's revealed this was AllJustADream and Saitama kills the leader of the real Subterraneans with one hit, prompting the whole army to surrender and leave.

* Played for laugh in ''Manga/MyMonsterSecret'' with BadassTeacher Akari, who decides on a co-ed dodgeball match for the new class… which means ''the entire class vs. her''. With weapons and shields allowed for the students. Despite all their elaborate battle strategies, she wins while barely breaking a sweat.
