Episode Summary: When she’s stressed out Hiyori spends her days near the ocean, fly fishing like she learned from her late father. Her meditative silence is broken one day, however, by a girl attempting to leap into the frigid March ocean. Hiyori uses her wits to help avert disaster, and she spends some time fishing with this girl, named Koharu. Koharu is impressed by Hiyori’s way with a fishing rod, and is even more impressed when Hiyori prepares fresh rock fish sashimi right there on the wharf. Hiyori feels drawn to this outgoing girl, and their meeting turns out to be more than just a chance encounter; Hiyori’s mother and Koharu’s father are planning to marry, which will make the two girls sisters.
After their families are joined and Koharu and her father move into Hiyori’s and her mother’s home, some of these big changes begin to make Hiyori feel withdrawn. Yet Koharu’s bright personality seems to be just the thing to help draw Hiyori back out of her shell. Koharu’s enthusiasm toward learning to fish certainly doesn’t hurt, either. As the two new sisters start the new school year, their future looks bright.
