Amanchu!

After leaving the bustle of the city for a quiet coastal town, Futaba Ooki continues to record her days through photos on her phone. Standing before the open sea, she’s drawn in by its calm scale and the sense that something new might be waiting beyond the shoreline. Her thoughtful presence doesn’t go unnoticed—local diving lover Hikari Kohinata takes an interest, and when they end up in the same class, Hikari’s bright friendliness and the nickname “Teko” become the start of an easy, growing bond.

Still adjusting to a slower rhythm of life, Futaba is swept along by Hikari’s enthusiasm for diving. The two join their school’s diving club under homeroom teacher Mato Katori, and with Hikari’s support, Futaba works toward earning her diving certification while opening herself up to new friendships and experiences.
