Age: 19
Affiliation: Tasogaredoki Castle ninja
He's one of the youngest members of the ninja team at Tasogaredoki Castle, and it shows—he's noticeably less experienced than everyone else on the squad. People constantly mess up his name, reading it as "Shosen Sonnamon" instead of the correct version.
Sonnamon's got a chip on his shoulder about Doi, who once beat him in a fight using nothing but chalk and an attendance book. That humiliating loss stuck with him, and he's been fixated on getting revenge ever since. The problem is, the skill gap between them is pretty huge, making the whole rivalry pretty one-sided. Fans often note that his determination to prove himself against Doi is more endearing than anything else—he's clearly outmatched but keeps trying anyway.
