Sewayaki Kitsune no Senko-san

Synopsis

As Senko is cleaning the apartment, she notices a flower design on a bento box that reminds her of Kuroto's childhood in a flashback. Later that night Senko senses that Kuroto is having problems at work, so she does something different for dinner to cheer him up. Meanwhile in the spirit world, Shiro complains that it's been a year since Senko came to help Kuroto. Yozora acknowledges this by telling her that she does not have to wait long to have Kuroto all to herself. After dinner Kuroto gets a phone call from his mother who tells him that his father has been hospitalized. Senko encourages Kuroto to go be with his family, and he gives her his phone to keep in touch. After traveling to his parent's house he finds that his father is okay. While there he visits his grandmother's grave and recalls his past with Senko. He tries giving her a call to tell her about it but gets no response in return.
