A 41 year old large, heavy-set, anthropomorphic walrus with permanent, tired-looking eyes. He works as a taxi driver in the busy streets of Tokyo, where everyone is an anthropomorphic animal. Odokawa is an eccentric, deadpan loner who speaks with a sharp-tongued, cynical directness. Because he spends his nights listening to various eccentric passengers, he has developed an uncanny ability to read people, notice inconsistencies, and piece together complex situations. Despite keeping people at arm's length to protect himself, he possesses a strong moral compass and deeply cares for his few friends, regularly risking his safety to help them. He prefers isolation, suffers from chronic insomnia, and unwinds by listening to rakugo (traditional Japanese comedic storytelling) or the radio. His favorite after work activity is taking a sauna at the local bathhouse.

Eiji Kakihana is Odokawa’s oldest friend, a 41 year old lanky anthropomorphic gibbon ape with prominent ears, light brown fur, and a distinct white patch around his face. Outwardly, he appears easygoing and cheerful, but he is deeply insecure, desperate, and financially irresponsible. Struggling with a severe inferiority complex regarding his low-paying job as a janitor, Kakihana relies on dating apps and elaborate lies to project a fake aura of wealth and success to potential romantic partners. He likes to accompany Odokawa to the bathhouse for a sauna, or to their local Izakaya pub for a drink / vent.
