I Want to Rebuild the House

Mastering Turbo Granny's speed, Okarun overwhelms the Evil Eye and headbutts it into the house, but he burns through both his All-Outs and loses his form. Rather than fight a losing battle, he tricks the childish spirit into a deal: the yokai may only challenge him, must grow stronger first, and may fight solely on Tuesdays. The Evil Eye hands over its underwear as a token and returns control to Jiji, who is comforted by Okarun and reassured he hurt no one. Manjiro takes the cursed briefs back to his shrine for safekeeping.

With money spent on a bathhouse trip, Seiko insists on rebuilding the wrecked home herself and refuses to lean on others, but Okarun arrives with Mantisian, Chiquitita, and a construction-savvy alien named Ludris. Using Ludris's nanoskin technology, which shapes materials from thought, the group reconstructs the Ayase house. Elsewhere, the fugitive Naki Kito is revealed to be searching for revenge. At school, Jiji's flirting with admirers nearly triggers the Evil Eye when a girl offers him a cold drink, forcing Momo to manage the spirit all day, which scribbles, shouts, and eats with its hands. Miko and Muko later tell Momo about the Apartment-Complex Ghost, a floating golden ball, while Okarun is confronted by a classmate who brands him an enemy.

The episode straddles the end of the Evil Eye Arc and the start of the Kaiju Arc, adapting Chapters 61 through 64. The classmate, Kinta Sakata, sings lyrics from Mobile Suit Gundam's "Char ga Kuru" and quotes Char Aznable. Jiji admits the Evil Eye has surfaced several times since the promise but has behaved, leaving him feeling closer to Okarun. Manjiro declares a new ambition to become a 'Sleeping Bag Bootuber.'
