Albino shiba inu and member of S.E.E.S. in Persona 3. Despite being a dog, Koromaru can summon a Persona, using a special collar as an evoker. He also wears a vest with angel wings (Yukari and Fuuka's idea) and a S.E.E.S. armband just like the rest of the party.
Modeled on the story of Hachiko, a Shiba-Inu who continued to wait for his master everyday at the station long after his death, he displays exceptional intelligence and loyalty.
