Punch Line

An incident causes Yutaro's soul to leave his body. As he searches Koraikan for a way home, he catches a glimpse of the female tenants' panties, leading to unspeakable disaster on earth! Why?!

Having failed in her requested exorcism, Rabura is feeling down. Meika has an idea to cheer her up. Meanwhile, a strange scream comes from hermit Ito's room.

Ito is beginning to suspect who Mikatan really is. Mikatan tries desperately to hide the truth. Meanwhile, a mysterious man, Miyazawa Kenji, invades, and Meika's true identity is also revealed.

Having seen an ominous video, Yuta learns that Ito is in danger. He tries to let everyone know by possessing Rabura, when Gliese, the man she has feelings for, shows up.

Yuta witnesses the worst-case scenario as was warned in the video.

Yuta brings an end to the video crimes, but the countdown to the end of humanity had already begun.

The panty panic is back! Now, everyone together! "Panty Panic! Panty Panic!" Many things are revealed, including the relationship between Yuta seeing panties and the end of the world.

Yuta interrogates the intruder, only to be left with even more questions. He also speaks with Rabura's brother, Randou, but the party at Koraikan goes on without anything being any clearer.

Concerned about Mikatan's health, Yuta tells her to stop her hero activities, but she refuses to listen. He talks to Meika to have her run physical exams.

The Human Salvation Project ends in failure, leaving Yuta in despair. Ito is abducted, and Yuta and Mikatan search for her at the shrine, where they learn the truth about everything that's happened.

Yuta pleads for Meika's help in saving humanity from destruction. The two begin "Operation Peacemaker," but to make it work, Yuta must defend Koraikan by himself.

What is the fate of humanity? Will humanity come to a supremely happy and peaceful future? What's the punch line?
