Amanchu!

Meeting Hikari has completely changed Futaba's life, but she starts to worry about how she'll cope if a day ever comes when they have to part.

While Futaba is away for a memorial at her country home, Hikari befriends a girl by the sea and puts into motion a plan to make a summer staple more exciting for everyone in the Diving Club.

Futaba takes the underwater navigation tutorial but is brought crashing back to reality by the realization that she may be holding Hikari back. And so, she makes a decision...

Futaba and Hikari spend an autumn day apart, and they both find autumn wonders of their own.

Futaba goes diving in a drysuit, as the gang looks to encounter the legendary Jet-Black Mermaid.

Hikari and Futaba finally meet their seniors in the Diving Club, but the meeting doesn't exactly go as planned...

It's Halloween, and the Diving Club members find themselves in the midst of a special event in an amusement park. Hikari's in danger, and it's up to Futaba to be her knight in shining armor?

The changing of the seasons affects the mood of everyone in the Diving Club, especially Katori Mato. However, she ends up finding ways to enjoy the moment with a little help from her friends.

The Yumegaoka High Dream Festival arrives, and the night before, the entire student body is busy preparing for opening day. This night would end up becoming a very special one for Ai in particular, as she has a very special encounter.

After meeting Peter in an encounter straight out of fantasy, Ai now gets transported to a fantasy world, where she meets someone she never expected to meet.

Ai can't accept how Peter parted with Mato-chan and her, and so she decides to head back to Neverland, only this time she has company.

Teko is invited to bring in the new year at Amanchu-ya, and she finds herself in the company of the whole gang plus a few extras. As they watch the first sunrise, a new kind of emotion takes over her and Pikari.

Pikari ends up with a cold on her birthday, so Teko decides to visit her at home. She finds someone on the way, which leads to plans for another fun event once Pikari recovers.

Futaba and Hikari take a walk down a path neither of them know, and end up finding a tiny kitten all on its own.

It's finally time for Teko's advanced certification test, with a promise of a night-diving celebration if she passes!
