Hikawa Kijuurou

"Ah! I'm sorry, I'm sorry! That was creepy, wasn't it? To suddenly do that... I'm sorry, I'm such a creep, I'm sorry..."

A man with an eyepatch who wanders into the Umebachidou at dusk. Real name Hikawa Kijuurou. While he always speaks politely and softly, his mannerisms are nervous and suspicious, and he constantly seems to be ill at ease. Tries very hard to smile often, but it always ends up looking very, very stiff and forced.

Appears to have become a regular customer at the Umebachidou only after Tamamori started working there, and very little is known about his background. While nobody knows what he's researching, he always says, "Please call me Doctor."

A collector of tin toys. Seems to have heard about Tamamori from somewhere and is a crazy, diehard fan of his works. Does things like giving Tamamori a tin goldfish watering can as a sign of friendship, creeping Tamamori out.
