Tsuritama

Yuki Sanada moves to the seaside town of Enoshima with his grandmother, carrying severe social anxiety that makes even ordinary conversation feel overwhelming. Then Haru appears, loudly claims to be an alien, and decides that Yuki is his friend. Haru drags him into learning how to fish alongside talented but guarded classmate Natsuki Usami. What begins as a strange hobby soon connects to a mysterious danger in the ocean and an even stranger mission to save the world. Between fishing lines and awkward friendships, Yuki discovers that reaching other people may be harder than any supernatural threat, and far more important to him.
