When Renge receives a bike from her grandma, she’s eager to practice so she can ride everywhere with her friends. But the rainy season is in full swing, so she sets about making a teru-teru bouzu in hopes that the rain will stop. Meanwhile, Renge is on duty to take care of the tadpole shrimp she caught while playing in a field, and she grows very fond of them.

Renge goes to visit Natsumi, but she and her family aren’t home. She’s about to give up and leave when a hand starts talking to her from the other side of the fence! She thinks it’s a monster, and is relieved to learn that it’s the next door neighbor Konomi. But Konomi then tells her that she is, in fact, a monster… Later, the Koshigaya sisters tell Renge they were in first grade when they took off their training wheels, so Renge starts to practice riding her bike without the training wheels.
