Yaiba

Everything About Fiction You Never Wanted to Know.

Yaiba (Ken'yu Densetsu Yaiba/Legend of the Swordsman Yaiba) is a Shonen manga written by Gosho Aoyama, known for Detective Conan and Magic Kaito. It starts out as a light, funny manga very similar to Dragon Ball but slowly becomes more serious towards the end.

The main character, Yaiba Kurogane is a Kid Samurai, trained by his father Kenjuuro in a unspecified jungle. They both return to Japan where they're "hosted" by Raizo Mine, an old rival of Kenjuuro. Here Yaiba meets Sayaka, Raizo's daughter and Onimaru, a highly skilled kendo master. To sum up, they become bitter rivals and Onimaru gets really obsessed with beating Yaiba. In order to do so, he tries to use the legendary Fujin Katana(Wind Devil Sword in some translations), which grants power over Wind Gusts and Typhoons, but the sword turns him into a evil Oni (demon) bent on conquering the World. In order to stop him, Yaiba, with the help of Sayaka and his pets Kagetora (A cowardly Tiger) and Shonosuke (a nice Vulture), goes on a quest to find and master the Raijin Katana(or Thunder God Sword), guarded by a 400 years old Miyamoto Musashi. After this, several arcs follow.

  • The Hakki Arc: Yaiba must learn how to master the Raijin Sword and fight the Eight Great Oni sent by Onimaru.
  • Kojiro's Revival Arc: Onimaru resurrects Musashi's rival Kojiro and Yaiba must face him. During this arc he finally masters the power of Raijin and learns a new attack.
  • Onimaru's Fortress Arc: Our heroes storm Onimaru's fortress in order to stop him, but that won't be easy. Onimaru is eventually forced to withdraw, but he steals Raijin's Orb and hires Professor Kanabo, a Mad Scientist capable of repairing the Fujin Sword (which was broken by Yaiba).
  • The Quest for the Legendary Orbs (Yes, in case you're wondering there are seven of them and they're required to summon the Dragon-God Ryujin, but he doesn't grant any wish, and none of said orbs is orange. In order to reach Onimaru's Flying Castle, Yaiba & Co go on a quest for the Ryujin Orb, but they need to find the Seven Legendary Orbs first... and fight back Onimaru's warriors resurrected from the past. From this arc onward, the series started growing more serious.
  • Kaguya's Arc: The return of Ryujin's power awakens the legendary Moon Princess Kaguya from her slumber, and Yaiba must protect the Earth (and Sayaka) from this alien menace, fighting back various enemies gifted with weird powers. Eventually Kaguya is sealed inside the Planet and Ryujin's powers disappear.
  • (a whole volume of Filler arc): including the funny "Chiki Chiki Grand Prix" Omake.
  • The Pyramid Arc: A mysterious Pyramid appears in Tokyo and starts causing earthquakes. Yaiba must venture inside it, defeats its powerful guardians and stop it before it's too late.
  • The Underworld Arc: Right after the Pyramid Arc: Yaiba must face the menace coming from the depths of the earth and find out why these mysterious enemies hate humans so much...
  • the Yamata-No-Orochi arc: Onimaru is trying to gain an "Otherwordly Power" by unleashing a legendary monster who was sealed away long ago, and our Heroes must stop him once and for all. probably the darkest saga, it also features the return of Kaguya and Ryujin. After a terrible struggle, Yaiba manages to defeat Onimaru once and for all, but in order to seal the Orochi away he must give up the Supreme King Sword forever.
  • The Oda Nobunaga Tournament: the last arc: Yaiba and friends meet a young girl, who reveals herself as Yaiba's little sister. Soon he finds out that his mother is still alive and very rich, and his father Kenjuuro might be an impostor. In order to find out the truth, he faces the legendary and dangerous Oda Nobunaga Tournament, armed with his father's wooden sword. Yet, a mysterious organization, the Platina, is after him.... After reaching the end, Yaiba must fight Onimaru, who was trained by Kenjuro himself and now is extremely powerful, and eventually manages to beat him, becoming the Greatest Samurai in Japan.... and yet he starts a new journey with Musashi, Kagetora and Shonosuke in order to become even more powerful.

An Anime was made, but it lasted only 52 episodes, covering the story from the beginning to Kaguya's Arc. Yaiba and friends appear in the Massive Multiplayer Crossover game, Sunday VS Magazine Shuuketsu Choujou Daikessen.

Now it has a Characters Page.


Tropes used in Yaiba include:
  • Absurdly Sharp Blade: Many swords in series are really sharp. Justified, because they're magical swords.
  • Achilles' Heel: Many villains have these. Including Bat-Man (weak to sunlight), the Moon Bunnies (their ears) and Silver's eye.
  • Accidental Pervert: Jubei at least once. All others are plain perverts and proud of it!.
  • Acrofatic: Goemon Ishikawa is quite large and plump, but he's a Lightning Bruiser when he fights.
  • Adaptation Distillation: The anime. The most lampant example is the first episode which managed to resume the whole first volume in thirty minutes.
  • Affably Evil: Goemon, who after all enjoys drinking sake and wouldn't hurt animals no matter what. Also Kaguya, who flirted with Onimaru... before parrying his wind slash with her fan an tossing a huge ki blast at him.
  • Air Jousting: Whenever Yaiba have to face a flying opponent. Usually with a little help from Shonosuke and later with the Ryujin Katana.
  • All Your Powers Combined: The Ryujin (Dragon-God) Orb can use the powers of the other seven Legendary Orbs and some other tricks. during the last battle against Kaguya, he must use this very trope in order to awaken the true power of the Dragon God.
  • Alluring Anglerfish: Yakitori, one of Onimaru's Shitenno in the Onimaru's Fortress arc. It actually has a Japanese paper lantern attached to it, and he's very proud of it. Oh, and don't call him "Toadstool"....
  • An Axe to Grind: Gerozaemon's weapon of choice. Also the Rock Soldier and Ruby in the Pyramid Arc.
  • Ancestral Weapon: Both Raijin and Fujin Swords are really old weapons from the past. Also many other swords.
  • Anguished Declaration of Love: Yaiba says a "I Like You, seriously." to an aged Sayaka before confronting Kaguya. After the battle however he jokes about it, so we don't know if it was serious or not.
  • Anime Hair: Yaiba. Also Kotaro and Goemon, whose hair resemble a Funny Afro
  • Anticlimax Boss: A non Videogame example: the second time Kotaro shows up in order to face Yaiba he's bisected by Rokuemon Ishida's attack. Justified, because Kotaro was totally unaware of his plans.
  • Artificial Human: The last guardians of the Pyramid, namely Ruby, Sapphire, Diamond and Emerald.
    • Gozuma from the Platina Corporation is a partial exception: He's fully human, but underwent a special operation in order to have some chips planted in his muscles, making him the perfect warrior.
  • Arrogant Kung Fu Guy: Takeshi Onimaru, before and after his transformation. Also Gekkou the Black Moon Bunny and Budou the Grapefruit Soldier.
  • Attack! Attack! Attack!: Yaiba's trademark strategy. Of course, if this doesn't work he's more than capable of finding out a solution against his foes.
  • Attack Its Weak Point: Done during the battle against Gold and Silver in the Underworld arc. it doesn't really work as well as hoped.
    • Yaiba defeat both Orochi and Onimaru by cutting their horns
  • Attack of the 50-Foot Whatever: This is the power of the Giant Orb of the Great Buddha of Nara. Also is Cast from Hit Points
  • Author Avatar: Gosho's name (or Gosho himself) tends to pop up frequently here and there.
    • He also appears along with the other characters (who refuse to acknowledge him and mercilessly mock him) in the Omake. He takes part in the race with the others but get zapped by God for cheating.
  • Badass: Jubei Yagyu and Devil King Onimaru . Also Young Musashi.
    • Badass Beard: Young Musashi sports one. He shaved himself before facing Kojiro at Ganryujima.
    • Badass Creed: The magical writings on the Fujin sword, that explain how to master it. Sadly, it' quickly forgotten.
    • Badass Grandpa: Musashi when he's not suffering from backache or peeping at some pretty lady or pillaging the nearest fridge he's a really skilled swordmaster, capable to fight toe-to-toe with powerful foes.
      • Never Mess with Granny: despite being frequently offscreen, Sayaka's Granma may count. Surely she's a really competent Kendoka, and had a Mama Bear moment in the first volume when Onimaru threatened Sayaka in order to know Yaiba's whereabouts.
    • Badass Moustache: Ryujin.
  • Bad Powers, Bad People: The Devil King Sword. In this case, the more wicked the wielder is, the more powerful it becomes.
  • Bald of Evil: Onimaru Takeshi sports one. Also the fallen monk Seikai Miyoshi.
  • Barrier Warrior: One of the powers of Ryujin's sword allows Yaiba to create an energy shield. Emerald is capable of summoning Barriers and healing people. Actually, she Is the Barrier Soldier.

  • Battle Aura: Many fighters. Also shown as a power with the Toujin (Battle Blades), a flurry of "ghost slices" that attacks the enemy from many directions and can only be "felt".
  • Beethoven Was an Alien Spy: The famous poet Matsuo Basho was actually a vicious assassin who wanted to use Ryujin's powers to take over the world, but died of illness while on his quest. And now Onimaru has resurrected him...
  • Beyond the Impossible: Seriously, some of the stuff that happens in this manga can be really over-the-top sometimes...
  • BFG: The Carbon-Freeze cannon and Gekko's Moonclub, which doubles as a Bazooka.
  • BFS: Despite having a lot of swords and weapons, Aoyama rarely uses this trope. Yet, Kojiro's Laundry Pole has the power to grow really really long.
    • Also the Devil King Sword (Mao Ken) is quite large compared to Gekko. Gold in the Underworld arc wields a gargantuan scimitar, but is quite justified because it fit its size.
  • Big Bad: Onimaru Takeshi, your typical Dark Overlord. Also Kaguya and, during the Pyramid and Underworld arcs, Boss.
  • Big Badass Bird of Prey: Kotaro Fuuma's true form is that of a Hawk-Man. Yaiba almost got killed by him.

  • Big Good: Ryujin the Dragon-God. Also Susanoo during the Yamata no Orochi arc.
  • Big Damn Heroes: Happens from time to time. During Orochi arc, Ryujin does this in order to save Yaiba and Sayaka from Dark.
  • Big Ol' Eyebrows: Musashi sports overly long eyebrows, long enough to make any Blood Elf jealous.
  • Bizarro Universe: There's a small world inside the Darkness Orb: it looks like a black swamp with the kanji for "Darkness" in the sky, a watermill and a small mountain with a waterfall. Also, the ground is composed by the remains of the previous victims whodied of old age without finding a way out. The only way out is hidden behind the waterfall, but is guarded by a giant fire-breathing carnivorous Kappa named Kerosuke.
    • On the other hand, all your wishes (except leaving the Orb) can become true.
  • Blade Below the Shoulder: Unlike the other Demons, Plasma uses two triangular blades protunding from his forearms.
  • Blade on a Stick: The Snakeman wields the Snake-God Pike (a four pronged elaborated spear), who is said to be unbreakable. Also Shiro Amakusa can make a golden spear out of his hair.

  • Breakable Weapons: Happens often with Musashi's and Jubei's katana, and with Laundry Pole (in that case the blade can grow back). Also the so-called Invincible Snake-God Pike and even Fujin Sword ( It got better). During the Yamata no Orochi arc, Yaiba's Supreme King Sword started cracking after blocking Onimaru's strongest attack only to grow even stronger later when the blade shattered and reveald its full power. The same goes for the Devil King Sword.
  • Breath Weapon: Kotaro's Fire Ring Justu. Also Demon-Gold.
  • Butt Monkey: Oooh boy, poor little Spiderman is a huge one. Onimaru never misses a chance for punishing him, insulting him and hanging him out of the fortress with a rope. He drop this habit later.

Spiderman: "Onimaru-samaaaaaaa!!! Please Forgive meeeeeeee!!!"

  • Calling Your Attacks: Yaiba Yaiba Yaiba. Also Onimaru and some of his enemies are guilty of this sometimes, often with bits of Gratuitous English.

  • Five-Man Band:
  • Flaming Sword: Yaiba when using the Fire Orb. or the Supreme King Sword for the first time. Also Gold who can heat up his blade. And let's not forget Burner's Fire Demon Longsword, who can set fire to everything it touches. Kojiro learnt that in the worst way possible.

  • God Is Useless: Amakusa tries to summon up to 36 gods to find out the location of the Legendary Orb of Kyushu, but he's hilariously unsuccessful.

    • Averted with Ryujin and Susanoo.
  • Graceful Loser: Jubei, Soshi Okita and, basically, all the millionairs who bet in the Oda Nobunaga Tournament to Yaiba.

    • When Ryujin got caught in Dark's Super Delta Zone attack, he puts a Taking You with Me in order to drag that evil monster with him.
  • Heroic BSOD: Yaiba has had only two short ones: first when Onimaru kicked his ass with the Fujin sword and later when he's utterly bested by Gekko and Sayaka choose to follow him in order to save Yaiba's life.
  • Hey, It's That Voice!: Yaiba Kurogane is Nabiki Tendo, Sayaka is Boa Hancock and Sailor Moon.
  • Hoist by His Own Petard:Kojiro is defeated by Jubei when he proves the lenght of his sword by standing on it and stretching it to the clouds. Jubei' answer? Kicking the blade and making him fall from Niigata to Tokyo. At least he landed in the women Dojo...

    • Also the Supreme King Sword and Devil King Sword's true form unleashed shatters the blade and create a laser one.
    • An interesting variation is the Water Demon Longsword, which can pass throught any solid substance and cut only flesh. But it can't parry blows... Awesome but Impractical.
  • Les Yay: As mentioned above, Kaguya needs to kiss the Life Force out of young and pretty girls in order to prevent aging. One particular scene has her (in her young form) kissing a girl in order to feed. Just Wow. And don't even talk about her obsession with Sayaka.. (because she's the key to Kaguya's One-Winged Angel form, mind you.)
  • Light Is Not Good: Gekko's name means Moonlight, but he's evil as hell. Plasma is a straight example.
