Kagetora
Kagetora's claim to fame is his unusual partnership with the Sacred Beast Wu—he's the "Chosen One" to this deity, and together they run a brothel. Before that, he was deeply involved in yakuza life, though he's since left that world behind.
He's the type who takes things seriously. Protective and genuinely responsible, Kagetora has naturally fallen into a mentor role with Kotone, looking out for her as she navigates whatever comes her way. It's a side of him that contrasts sharply with his rough past, suggesting there's more depth to him than his yakuza background might initially suggest.
