Ookami-Otoko, called Wolfman, hails from Monster Land and serves as a core companion to Tarou Kaibutsu during their journeys to the Human Realm. He acts as the group's dedicated housekeeper and cook, managing domestic duties and meal preparation. A unique speech pattern defines him, as he unfailingly appends "gansu" to every sentence he utters. Within the live-action television drama adaptation, he gains a daughter—a familial dynamic absent from the source material, representing a narrative expansion exclusive to this interpretation. Wolfman engages in confrontations against antagonistic forces, chiefly members of the demon group Demonish, fighting alongside Tarou and companions like Dracula and Franken. His portrayal consistently depicts a steadfast and reliable supporter in the group dynamic.
