Okita Souji

403
Okita was the captain of the first unit of the Shinsemgumi. They were a small group of elite swordsmen made up of commoners and low ranking samurai's. They were a police force meant to protect the Shogunate in Kyoto in the mid 1800s. Okita was seen as a genius swordsman and admired as one of their strongest members. Unfortunately, she passed away at a young age due to tuberculosis. When summoned, Okita is a Saber and is kind and loyal to her master. Rather than acting like a cold-blooded person during her time with the Shinsemgumi, she's more innocent and playful.
