Kin Gaku
Kin serves as one of Kouen Ren's household members. He's a massive, heavily built guy—the kind of person who takes up space in a room. He's got a pig-like nose, a round face, and dark hair, mustache, and teeth that all match. His typical outfit is Kou style but sleeveless, which lets you see his seriously muscular arms. He rounds it out with chest armor, a neck scarf, a head wrap, and carries what looks like a spear around.
