所知不多，但由一些記述了解他弱強者生弱者亡的道理頗重視。
Not much is known about Biba. His ruthlessness and complex personality can be easily misinterpreted. It is yet unknown whether this twist in personality emerged after being betrayed by his father, or because of an inherent streak of callousness.

Biba taught Mumei that the weak die and the strong survive, and that one must choose to fight in order to be strong. He makes Kabaneris out of the "weak" and uses them as personal combat troops, perhaps by manipulating their need to be strong. Mumei's panicked words, "But I'm not weak!" when she was afraid of turning into a Kabane in episode 6 hints that Biba turns the Kabaneris he deems weak into Kabanes. He has a policy of "discarding" or banishing people who are too injured to serve, as Enoku and Mumei notes. In Enoku's case, Biba harboured suspicions about Enoku's loyalty.

Mumei, also known as Claw of the Liberator, addresses him as "Brother" (兄様, *Ani-sama*). She looks up to him to the point of idolatry, frequently quoting him and even talking to him in her sleep. She even goes so far as to hit Ikoma and call him a liar when defending Biba against Ikoma's accusations. However, Biba does not appear to genuinely reciprocate her affection, only praising her to use her. It is still possible that he does hold some admiration or respect, possibly affection for her unwavering loyalty and lack of hesitation.

Biba appears to be very charismatic, judging by his popularity with the common people and the respect he commands from Mumei, despite the fact that he renamed her "Mumei", which means "Nameless". Even Enoku, known as former Ear of the Liberator, desperately wanted to "continue serving the Young Master away from the frontlines" by acting as a double agent. It is implied that Enoku faltered in his mission years ago and is thus dismissed. Biba reads Ikoma easily and knows exactly what to say to win instant kinship.

Biba is politically astute and deceptive. The antithesis of Ikoma, he garners a reputation as a Kabane exterminator and land liberator for the people, but his true goal is to reach Kongoukaku and organise a coup to seize power from his father and obtain revenge for being betrayed. He tries to manipulate Mumei into robbing the master key from Ayame, after gallantly offering to "escort" Koutetsujou to Kongoukaku. A cunning strategist, Biba sees through his enemies' numerous attempts at assassination very quickly.

Biba is obviously very skilled in combat with a gun-sword coated with Kabane heart metal, and commands his battle horse at an almost psychic level. He devises the Hunters' effective battle strategies himself, and is gifted at military leadership. It is suggested that Biba trains his Hunters himself.

Making Biba even more dangerous is his skill with technology or resources he has at his disposal. Biba's Hayajiro, the Kokujou, is extensively modified and carries perhaps the most advanced Kabane technology or research. It is revealed that he was the one who turned Mumei into a Kabaneri. The Kokujou has an experimental centre/makeshift interrogation chamber that keeps an artificial Kabane fused colony called the Tsutsugamidokoro. Biba works on the Kokujyo himself, suggesting he is at least as good as Ikoma at engineering. Whether he wanted to work on the engine himself in order to impress his visitors, or because he trusts his own workmanship more.

Ikoma strongly believes that Biba is no hero, because as a Kabaneri with enhanced eyesight, he witnessed Biba smiling when he disarmed and killed Enoku after Enoku's failed attempt at assassinating Biba.

劇情
--

在早期的集數中他多次提到，在第6話中，也出現在無名的記憶中，他是在無名的母親被殺之時，救了無名的人。

在第7話，他帶領著狩方眾出現，為倭文驛的民眾所歡迎。 雖然是將軍大人之子，但是作為獨立的力量，幕府中也有人要對他不利。榎久在第5話中有對無名提到幕府的動態，顯示對美馬有一定的忠心。

在第8話中美馬與菖蒲見面談話，菖蒲則說一路上受無名的照顧，沒想到是美馬的妹妹，但美馬說並不是真的妹妹，無名說只是她想要這樣叫而已。接著，無名介紹了生駒給他，他一見面就說，就是你跟無名說弱者只有死吧。無名想阻止他說下去，美馬把她支開了，要好好跟他們談。

於是菖蒲來棲和生駒等跟他一起走，他講到跟將軍大人已斷絕關係的事，接著看到整修駿城的人說蒸氣外漏，他親自拿扳手去修理。請他的手下滅火先帶路，生駒則說讓他也一起來幫忙吧。

美馬和生駒討論強者弱者的問題，生駒不認為要捨棄弱者，美馬則說這不是為了捨棄，而是拯救，無名就是努力才活下來的，生駒問說是如何，美馬則說要活下去不是躲起來，而是勇敢地去對抗卡巴內吧，生駒聽了深有所感，這時突然出現大量的卡巴內要來攻擊驛，美馬問生駒是否要作戰，生駒說是。於是約好戰場見。

美馬和他的部眾問清狀況數量以及沒有融合群生態之後 ，說15分鐘就能解決。倭文驛和甲鐵城的人們在想如何對付時，驚見橋放下，美馬和其駿城出城而去，先發射燒夷彈，接著騎馬和機車出去，很迅速地殺死大量卡巴內，城內的人十分驚訝，生駒此時也出城去近身殺敵，有一人拿著望遠鏡注意到他。有一個高大技取十分難纏，無名說我來負責，美馬讓滅火前去幫她，最後將之解決。

這時榎久出現在戰場上美馬前面，告訴他有很多人想殺他，他也是被命令而來，但如果美馬願意再命令他，他願意說出那些人的所在，並且繼續幫他作戰。美馬拒絕了，榎久於是向他揮刀，美馬打倒他，說他說謊，一開始就是想加害他，然後說他很弱，把他殺了。一旁看到的生駒很生氣，向美馬質問，美馬說你認識這個人嗎為什麼這麼生氣，這時逞生和菖蒲趕快出來打圓場和抱歉。

這時美馬的部下殺死了買兇之人（應是小源太），並把倭文譯的首領帶走。美馬則原諒生駒，並說要護送甲鐵城去金剛郭。這讓車裡面的人都覺得放心，菖蒲雖覺得不確定是否這樣對，但也接受。生駒和逞生在講話，講到他對於美馬把無名變成卡巴內里不滿。無名回想到以前，被美馬訓練戰鬥，改稱無名，以及變成卡巴內里的經過。

這時美馬要求無名去把甲鐵城的主鑰匙取來。無名遲疑，他說菖蒲比妳弱沒錯吧，她只好答應。後來她取了假的鑰匙很快被美馬發現。

美馬在逼問倭文驛的首腦廣塚，說十年前的戰鬥中（他們負責糧草）是誰把他們捨棄在卡巴內里之中，他嚇得說出是主公的命令。

生駒跑去要求克城開門，美馬讓無名出來應付她。

## 人際關係

Biba harbours a deep insecurity of being betrayed. To compensate for his father's betrayal on the battlefield years ago, he adopts an extreme worldview, which he passes on to Mumei: "Live on your own. Don't rely on others." He also ruthlessly kills those whose loyalty he doubts eg) Enoku. Even more scarily, he seems to subject servants he suspects to the interrogation chamber/Kabane experimental centre Tsutsugamidokoro. When Ikoma confronted Biba over his worldview, Biba sends Mumei off to the Tsutsugamidokoro for revealing such personal and controversial information. It is unknown what occurred, but Mumei is next seen waking up on the medical examination table. Next, Biba sends her on a mission that will test her true allegiance - to steal the master key from Ayame. He is quietly pleased when she discovers that Yukina and Ayame had lied to her.

Biba does not appear to have any close relationships or fighting partners. He keeps his relationships professional, although he shows regret or sadness when his servants die eg) Shimon. This avoidant behaviour could also be due to the betrayal he experienced, or the hard life of the battlefield. He is mostly seen around Mumei.

**無名**

Mumei is one of his closest soldiers, and was the only Kabaneri left on the Kokujou when she was dispatched on a secret mission. She is not irreplaceable though; Biba had already created another when she returned, called Horobi. Mumei is the only Hunter that calls Biba (or is allowed to call Biba) "Brother". She is also the only one who treats him like family, understanding his true goal of reaching his home, Kongoukaku. However, Biba readily refutes assumptions that she is his sister, perhaps to thwart political enemies who would use Mumei against him.
