When the family cat is accidentally killed, zombie buff Chihiro Furuya secretly tries to bring it back to life. After he overhears Rea Sanka shouting her frustrations down a well, Rea offers to help Chihiro, as they both keep each others’ secrets.

Rea continues to assist Chihiro’s attempt to reanimate Babu. She reveals her home life, including an unhealthy relationship with her father. The two of them decide to make one last attempt to bring Babu back to life, using a hydrangea blossom.

Rea is grounded indefinitely for sneaking out at night, and her father decides to keep her home from school, for good measure. She sneaks out again anyway, and goes looking for Chihiro. Elsewhere, when Babu runs away, Chihiro and Ranko chase after him.
