After encountering the Mini Kaiju, Ibuki rushes around the university looking for a place to hide it. Meanwhile, Kyoko Shiga, an investigator from the mysterious organization UTTF, begins to take action against the kaiju threat and contacts Professor Minobe of Meishin University.

Ibuki breathes a sigh of relief upon finally finding a hiding place for the Mini Kaiju—but his relief is short-lived as a welcome party for his joining of the Astronomy Club suddenly begins!?

Emma suggests that the Astronomy Club should take care of the Mini Kaiju, now named Pucchi. However, Ibuki proposes sending Pucchi back to its home planet using the Space Pod found in the mountains where they first met. Meanwhile, Professor Minobe is planning a workshop in those very same mountains, risking Pucchi's existence being discovered by the public! Ibuki participates in the workshop, where he spots Kanna, a fellow member of the Astronomy Club.
