Hajime Saito is very tall and thin, and is a man who fights for peace, kills the evil, and lives for justice. He often speaks his mind, hence people often find him annoying and irritating. Because he was part of the Shinsengumi, he lived by the words "Aku Soku Zan". Saitou is the cold Shinsengumi member. He took a job as a police officer after the Revolution, during which he fought against Battisai. He hates evil, hence his constant saying of Aku soku zan.
