Izumo/Nagamine Kazuto

Kazuto's parents died when he was little, during the Bakumatsu era. Since then he had lived with his grandmather in the country side, while his younger sister Youko went to live with their uncle.

Growing up with his grandmother, he follows his grandmother's teachings, and has a very gentle personality. Too gentle, some might feel, to the point of not being dependable. However, when his friends need help, he would be able to lose hesitation and summon up the courage to protect his friends.

He is a practitioner of the Nagamine style of swordsmanship.

When his grandmother passed away, he followed her instructions to seek out a certain Kiriya Gorou, who lives in Yokohama.
