Souji Okita is the captain of the first unit of the Shinsengumi, a special police force in Kyoto during the late shogunate period. He is one of the best swordsmen of the Shinsengumi.
Souji Okita is depicted as incredibly young, possibly a teenager. His long, black hair is tied back in a ponytail. He wears a checker patterned scarf, and traditional Japanese robes. Most notably of all are his eyes. They seem to posses a feline quality to them, as his pupils are slits.
Little is known about Souji's personality.
