Baiken is a hodgepodge of samurai tropes. While her initial design does come from Kenshin of Rurouni Kenshin (whom Ishiwatari thought to be a woman at first,) Baiken is quite a lot more than just that. She gets her scar and lost arm from the literary character of Tange Sazen, though which eye has been scarred has been switched around. While Sazen is a man, the very second movie the character starred turned things around and starred Michiyo Okusu as Lady Sazen in Lady Sazen and the Drenched Swallow Sword.
Certainly we can trace some elements of Baiken’s designs to characters like Tezuka’s Hyakkimaru as well, but all this really is to show that Baiken encompasses characteristics from an archetypical ronin samurai stories, including her traumatic past and thirst for revenge. Hell, she even kicks tatami up with a special move, and let’s not forget she gets her name from Baiken Shishido, who probably influenced her use of Demon Tools through his proficiency with the kusarigama, the sickle-chain. However, I do argue that Lady Sazen and Kenshin were the main influences here, and everything else was more or less a supplement to fit popular samirai tropes. Hell, she even has a pose where she holds her chin like Sanjuro from Yojinbo. Let’s get it on after the jump.
