Sakamoto Days characters

Sakamoto Days follows Taro Sakamoto, once the most feared hitman in Japan, who quit the job when he fell in love and now runs a small neighbourhood convenience store with his wife Aoi and daughter Hana. He has gained a lot of weight and promised Aoi he will never kill again, but old enemies and a bounty on his head keep showing up at the counter. The cast falls into clear groups: the store crew of former criminals, Sakamoto's family, the Order (the elite enforcers of the Japan Assassins Association), the group of killers led by the figure called Slur, and the students of JCC, the school for assassins. This page covers 16 characters as they are first introduced, without spoilers.
