170cm/58kg, 18 years old. A beautiful boy with light brown hair and red eyes. He generally gives off a cute impression, but he usually maintains a poker face. A refreshing flower boy. Furthermore, he has a slim yet solid muscular build. He is delinquent and selfish. He is stubborn, competitive, and hates to lose. Like a child, he stakes his life on trivial competitions, and it goes without saying that he causes great damage to his surroundings in the process. He has a bellicose personality. He is a guy who never shows his weaknesses. He is cocky, arrogant, and seems indifferent and relaxed about everything, but he has a delicate side, even calling himself a glass sword. He enjoys tormenting others but has no immunity to being on the receiving end. While he appears arrogant on the outside, he often shows severe self-deprecation in serious moments. He looks like a psycho, and he actually is one, but surprisingly, he has a very loyal and affectionate personality. He is very devoted to the people he likes and will risk his life for those he cares about. Also, he has a very strong sense of justice and a thorough sense of duty as a policeman. He is an extreme sadist, but while his sadistic character is most prominent and tends to overshadow other traits, he is actually the person with the strongest sense of justice and duty within the Shinsengumi. He has a clean personality that cannot turn a blind eye to corruption or compromise with injustice. He holds the philosophy that "there are things that must be protected even if you have to get your hands dirty." Seeing him assert that it's natural to be hated if you kill people, or that there are things you must do even by staining your hands, shows that he understands the nature of their work beyond just teenage righteous fervor. On the other hand, he casually self-deprecates, calling himself trash or a murderer who is already tainted. He tends to be very obsessed with protecting things because he believes that if he fails to protect what must be protected, he is no different from a murderer rather than a policeman. Although Okita is unfazed while killing countless enemies, he shows great agitation when he fails to protect his targets. He has a thorough sense of duty to protect civilians. He usually seems to hate working and slacks off while taking naps, but as the captain of the 1st Division, the primary assault unit, he is very serious about raiding and wiping out Joui patriots. Fundamentally, he has no aversion to killing itself and even enjoys it a little.
