Renge, who is about to start first grade, goes with the others to check out the school before the entrance ceremony, before seeing Hikage off as she goes to Tokyo. The next day, as Renge and the others enjoy the entrance ceremony and begin their first lessons, Hotaru starts moving in.

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.
