Makoto goes on a day out with Ryūko, who explains her stance on mysteries. Makoto relays what Meme had told him to Erio, though she seems reluctant to respond. Later, Meme tells Makoto not to get involved with Erio. Though he still wants to help her, Makoto decides to dispel her belief in aliens as the first step. He attempts this by taking her on her old bike and riding off a hill to disprove her ability to fly. The hill turns out to be a bit too steep, and they both go flying into the sea. Erio starts to come to terms with her being a simple Earthling and manages to introduce herself properly to Makoto.

Makoto and Erio continued to be bothered by the spacegirl, who later introduces herself as Yashiro Hoshimiya. Later that night, Ryuko calls Makoto about her upcoming basketball game, asking him to accompany her to the festival if she is able to play in it. The next day, Meme has Makoto take Yashiro back to her place, stopping by a pool along the way.
