Okami l'homme loup is a werewolf and the romantic partner of Hana. Orphaned young, he lived with relatives before fleeing strained relationships in his teens, leading to a solitary life sustained by work as a furniture mover and delivery person. Though not formally enrolled, he frequently attended university lectures. There, during Hana's second year, they met. Their relationship deepened after he revealed his ability to transform into a wolf, a trait he believed made him the last of his kind. Despite inherent challenges, they committed to building a family.

Hana bore their two children: Yuki, born during snowfall, and Ame, born during rainfall. Both inherited his lycanthropy. He exhibited strong paternal instincts, often hunting to provide food. In human form, he had short black hair with a distinctive bang, blue eyes, and slight stubble, typically wearing practical attire including a white shirt, dark blue sweatpants, sandals, and a black winter coat with a white fur collar. His wolf form featured dark blue-grey and white fur, with head fur mirroring his human hairstyle. He could partially transform specific body parts, such as shifting his hands to paws without a full change.

His life ended abruptly in an accident shortly after Ame's birth while hunting for food; circumstances suggest a fatal fall into a canal. After his death, he appeared to Hana in a vision during a crisis, reassuring her their children would find their own paths and affirming her efforts in raising them. This posthumous appearance marked his enduring symbolic presence embodying the reconciliation of dual identities and the challenges of living between human and animal worlds.
