Bojji is the main protagonist in Ousama Ranking. Though dismissed as deaf and dumb by most of the Bosse Kingdom, Bojji is actually intelligent, empathetic, and hyper-aware of the people around him. He is kind to a fault, and extremely giving of himself, even in situations where he may be hurt or humiliated.

Bojji is extremely hard-working and sincere, traits that tend to draw people to him even if they can't always understand him.
