Hiyori and Koharu fishing

Slow Loop is a Slice of Life manga about recreational fishing, written and illustrated by Maiko Uchino. It began serialization in Manga Time Kirara Forward magazine in September 2018, with an anime adaptation that aired as part of the Winter 2022 season. The series is licensed by Funimation, and follows Hiyori Yamakawa, a first year high school student whose father had passed away three years earlier from an illness. With her mother remarrying, Hiyori grows nervous and pays a visit to the ocean, where she meets the energetic and curious Koharu Minagi. After showing her the basics of fly fishing, Koharu becomes hooked, and to both girls' surprise, it turns out that Koharu's father will be marrying Hiyori's mother.

Hiyori and Koharu thus become step-sisters, and with Koharu's interest in fishing piqued, Hiyori promises to introduce her to some new techniques. When their term starts, Koharu and Hiyori are joined by Futaba and Ichika Fukamoto, Aiko Ninomiya and Koi Yoshinagi.

Slow Loop provides examples of:

  • Always Identical Twins: Koi's younger brothers, Niji and Tora.
  • Bears Are Bad News: During their camping trip, Koi tells Koharu a frightening story involving bears, although the specific story is different depending on the medium; in the manga, Koi tells Koharu about the real life Sankebetsu brown bear incident, wherein seven people were murdered by a bear in 1915, whereas the anime replaces this with a story about Hiyori and Koi's fathers coming across a bear in their tent during a camping trip, but able to escape with their lives.
  • Birthday Episode: The final episode of the season partially focuses on Koharu's birthday and Hiyori struggling to find a good present.
