Amanchu! ~Advance~

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.

An unaired episode bundled with the seventh BD volume of the Amanchu! anime series.

Haruka Nanase, now attending college in Tokyo, has an unexpected encounter with Shiina Asahi, an old friend and teammate from his middle school years. This encounter leads old and painful memories to resurface, while new challenges await on the road to competing on an international level.
