A youkai known for his unwavering loyalty and willingness to put himself on the line for his friends. He's the type who'll sacrifice everything for the people he cares about, and that devotion only deepened after he became a Shikigami—he's genuinely devoted to his master.
That said, he wasn't always like this. He used to be a vicious creature that attacked humans without hesitation. His best friend is basically the reason he's a different person now, having helped him turn his life around. Fans often note that his character arc really drives home the series' message: that friendship and compassion matter more than raw power or violence.
