Kouzaburou Arase

A member of Shinjuku Precinct's 'Sansan' unit and a subordinate under Tsubaki Iwanome. Despite his rough appearance and tattoos that make him resemble a street thug, he consistently communicates with polite, formal speech—a striking contrast to his looks. A firm believer in resolving matters through force, he once single-handedly dismantled the group known as 'The Hungry Ghosts of Sanzu River,' earning him a fearsome reputation as a combat-ready officer throughout Shinjuku. When dealing with supernatural incidents, he serves as both a powerful support and a steadying check for Iwanome.
