Sewayaki Kitsune no Senko-san

Synopsis

Kuroto arrives back home to find Shiro, a second fox demi-god, in his apartment. He stares at Shiro's tail, and she notices. Trying to upstage Senko a little, she lets him touch her head. It worked, as Senko got jealous and wanted to be petted too. Shiro thinks Senko is doing a poor job with Kuroto, so she uses her fox-fire to look at Kuroto's deepest desires; he wants to touch Shiro's tail. Shiro got scared by him and leaves, passing through the wall to Koenji's apartment. Shiro apologizes to Koenji, and departs. Though it surprised her, Koenji thinks that she has gotten less sleep and is hallucinating. The next day, Senko prepares a bath for Kuroto. She wants to take a bath with him too, in hopes of making him feel better. He washes her back and saw that her tail looks damp, making him feel depressed. They got out of the bath and Senko's tail is back to normal, which he wanted to touch again. That night, Shiro keeps a watchful eye on the two from outside.
