A male university student one year above, living in the same student apartment building. Black hair with somewhat sharp eyes, tall and slightly hunched, walking in a worn-out gray hoodie and jeans. Blunt and terse in explanations, but when the other person gets scared he says nothing and steps forward to become a wall. He casually speaks words of taboo like ghost marriage and yorishiro, and hits the mark by intuition rather than logic. When he gets a bad feeling, he talks less, turns serious, and then takes one step forward first.
