Oyassan

Owner of the Houhoulan shop. His real name is Yoshirou Azuma. Human. Height is 197 centimeters.

He is in his 50s and is called "Yoshi-bo" by Yuhi and Jinroku. He has a rugged, bear-like face, but his inner self is kind and delicate. He thinks of Rin, of course, and later Zakuro, who targeted Rin during the half-demon commotion, as his own daughters. He was deeply depressed when he learned that Rin's injury was caused by humans.

In the past, he was a refreshing young man, so much so that Ao and Momoka, who saw him in photos, were surprised by the gap with his current appearance.
