Shopkeeper

"Calm down, my boy, and try counting to a hundred."

Owner of Umebachidou Antiquarian Books. A generous landlord who lets Tamamori stay on his second floor for practically nothing after the latter was chased out of his prior lodgings. Appears to be chronically ill and entrusts Tamamori with the storefront.

Has the strange policy of only opening for business on rainy days. It's unclear whether this is profitable, but he doesn't seem to be in any trouble financially.

Always shuts himself deep inside his room. Even Tamamori has only talked to him through the sliding paper door. Judging from his voice, he's in his 50s. Always gently warns Tamamori when he's about to lose his way.

He doesn't know that his store has a basement.
