The Story of the Cat and the Kitten
Futaba and Hikari follow the club's mascot, Cha, leading them to take a path that neither of them has been down before. Along the way, they come across a small kitten that appears to have been separated from her mother. With neither girl able to take the kitten in, they decide to ask around at school for a potential owner, eventually getting found by Mato, who reminds them of responsibility involved in taking care of a life. Hearing Futaba wants to help the kitten like she helped her, Hikari convinces her mother to let the kitten stay at her house until they can find an owner. Just then, the school's principal, who is Cha's owner, decides to take in the kitten, who is given the name Ohime.

Amanchu!
Hikari Kohinata is an overwhelmingly cheerful and outgoing 15-year-old girl who has spent all her life in a small and beautiful seaside town on the Izu peninsula. On the first day of high school, she meets Futaba Oki, a slightly introverted girl who has just moved from Tokyo. Before she knows it, Futaba gets dragged along into Hikari's passion for scuba diving. And from there, Futaba gradually starts to come out of her shell, and learns how to take challenges and dive into the ocean of life.
