Sankarea: Undying Love

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 help Chihiro try to reanimate Babu, revealing her home life and unhealthy relationship with her father before the two attempt to bring Baby back to life with 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.

Aria learns that Rea has run away, and Dan'ichiro vows to get her back. In Chihiro's room, Rea sews up her wound, and the two of them each come to terms with her rebirth as a zombie. Free of her father, Rea reveals to Chihiro what she now wants from him.

Chihiro tries to determine the best way to preserve Rea's body, and makes a surprising discovery about his own grandfather. Plus, Ranko learns more about Rea.

Rea's strange behaviour leads her to kiss Chihiro in front of Ranko. After Rea slips away, Chihiro learns some valuable information about the undead from his grandpa. Chihiro decides to start keeping a diary of his observations of Rea.
