Asahi tells his friends that he decided to be just friends with Yōko for now. Meanwhile, Nagisa reflects on how she brutally rejected Asahi the previous summer to prevent him from getting too close to her, but now acts jealous after seeing him with Yōko. Later, Yōko eats her lunch with Asahi in an otherwise-empty classroom, and finds some cream puffs that Nagisa left on his desk, but the puff is too spicy for her to eat. She inadvertently reveals her wings as Nagisa steps into the room, but Nagisa in turn accidentally reveals herself to be a tiny alien, stepping out of her human-sized "External Unit" while holding a tiny raygun at Yōko. While worrying about her own secret getting out, Nagisa chases after Asahi with a hammer she refers to as a "Memory Erasure Apparatus," but Yōko saves Asahi from getting hit by it. In the end, the three decide to keep each other's secrets safe, while Mikan is shown digging a listening device out of an uneaten cream puff.
