Slow Loop

Hiyori Yamakawa has known her father's varied oddities since she was a young girl, but one thing she has always enjoyed doing with him is fly fishing—a challenging but satisfying manner of catching fish. Hiyori continues to enjoy her father's keepsake even after his untimely passing, going to the beach whenever she has free time. Three years later, Hiyori's mother chooses to get married again, and to celebrate, she hosts a dinner for Hiyori, her fiancé, and his daughter. Hiyori, who is anxious and trying to kill time, is at her customary fishing site when Koharu Minagi, who is quite vivacious, arrives out of nowhere. The two quickly grew close, and Koharu developed an interest in fly fishing as well. Koharu turns out to be Hiyori's future stepsibling, so their chance encounter is more than just a coincidence. This is just the beginning of the priceless moments the two of them will relive as they strengthen their sisterhood.
