Clash! Space Kaiju vs. Giant Robot!

Button-mashing fails to start the mecha, and Okarun and the Evil Eye are both ejected as the kaiju attacks. Realizing the machine answers only to visualization, Kinta takes control and tunes it to his own specifications, briefly dominating the fight while shrugging off memories of past ridicule. The kaiju turns invisible and cripples the mecha's leg, then thrashes it with its tail until Kinta cannot eject. Momo, sickened by the motion, reaches through the robot to seize the creature's tail, and Aira's hair pinpoints its location.

Momo channels her power through the mecha's arms to lift the kaiju and slam it down in a powerbomb, shrinking it and knocking it out. The trio returns to the real Kamigoe City, and Momo reshapes the mecha into a UFO to fly home. Okarun revives Jiji with a hot meat bun, and the group examines the unconscious creature. Finding a person inside its mouth, Okarun unzips the kaiju to discover it is a piloted suit with a girl within. As she stirs and locks eyes with him, the alien girl kisses Okarun, leaving a nauseated Momo and the others stunned.

This is the final episode of the second season, adapting Chapters 69 through 71 plus the Volume 9 omake within the Kaiju Arc. The episode is dense with Mobile Suit Gundam homages, including Kinta's fivefold-power remark echoing Amuro Ray and the mecha's rise mirroring Char Aznable's Z'Gok. Camera work during the fight draws on the Ultraman kaiju battles, and Momo's reaction to the kiss mirrors her shock at hearing Okarun's real name in Episode 1.
