A guide spirit of the underworld and younger brother to Kuro Mujou. He's basically the responsible one of the pair—way calmer and more dependable than his older brother. You'd describe him as hardworking, diligent, modest, and genuinely respectful.
That said, he has this habit of brushing off or outright rejecting Kuro Mujou's attempts at kindness and concern, which probably frustrates his brother more than anything else.
