First person: I (Watashi / Okita-san when relaxed). She usually speaks in a light, polite tone, behaving with a soft-spoken yet cheerful and slightly mischievous demeanor. However, in battle, she reveals a cold outlook on life and death and a ruthless tactical sense, showing no mercy to anyone. Despite her neat and refined appearance, she is somewhat of a meathead when it comes to combat, being aggressive enough to say things like "A serious duel is all about spirit" and "If your sword breaks, use the scabbard; if the scabbard breaks, use your bare hands" (which is actually faithful to the history of Tennen Rishin-ryu practitioners). While she takes great pride in her skills as a master swordsman, she has no particular attachment to the way of the samurai. If it's useful, she won't hesitate to use pistols or even missiles alongside her sword. She possesses an extremely dry personality, capable of cutting down even those close to her without batting an eye if ordered. This isn't due to the ethics of the Bakumatsu era, but her innate temperament; she shows little interest in personal ideologies. According to Yamanami, only Kondo or Hijikata could truly control her, and she was somewhat detached even among her comrades. When told she was to assassinate Serizawa, with whom she was on good terms, she agreed without a moment's hesitation, a coldness that reportedly froze even the "Demon" Hijikata. She doesn't particularly enjoy killing; to her, it is simply a necessity for survival. Furthermore, she possesses a warm, human side: she gets worn down and depressed by a life of constant fighting (meaning she isn't mentally unbreakable), actively plays with local children, and cares about practical benefits, trends, and social standing like any normal person. While possessing these normal human sensibilities, she feels that as someone whose only merit is the sword, she should die on the battlefield and secretly wishes for that. Her desire to "fight to the very end" stems from her regret over dying a lonely, peaceful death in a sickbed. She is a complex individual, as if "a non-human blade is hidden within a human heart" or "a heart has sprouted within a blade." She has an incredibly strong appetite for pickled radish, dumplings, and the like. She especially loves konpeito and sweets; even in serious situations, her pace gets thrown off when food is involved, highlighting her "mischievous" side. Regarding romance, her outlook is a mix of a devoted "I want to love you with all I have now because I might die today" and a conflicted "Is it okay for a manslayer like me to love?" It is very pure and slightly heavy. She loves going outside and has recently become well-adjusted to the modern cityscape.
