|Japanese name:||瀬田 宗次郎|
Sōjirō is often seen smiling and has polite manners, always referring to others with Japanese suffixes. He is sarcastic, hiding his true emotions behind his smiling face. However, he does have a special relationship with Komagata Yumi, who functions as an older-sister figure towards him. Sōjirō usually dresses up in a blue kimono with white handguards.
