Jofuku/History

Synopsis
The mysterious bartender

First season
A One-of-a-Kind SAGA : Kotaro told him about the Zombieland Saga Project, knows who Yugiri is and that she is part of the project, when, as seen in previous episodes, zombies are not allowed to give their real names or interacting with others outside of being idols, and he protects her, warning Kotaro to keep his hands off her because he owes her a lot. "And how long have you been talking?" He suggests that he may well have known her in his lifetime, making him at least 150 years old. He is also familiar with Kotaro about the good old days, a trait he doesn't show with girls, considering that he met Yugiri when she was alive, he could be an immortal or a zombie himself.

Good Morning Again SAGA : Small on-screen appearance when Yugiri sings her part in the song "FLAG wo Hatemekasero"
