Bojji is the crown prince of the Bosse Kingdom, son of King Bosse and Queen Sheena, step-son of Queen Hilling, and older brother of Prince Daida. He is the protagonist of 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.
