Neptune, IF, and Compa visit Chuko's store one day, and see her depressed. They ask what's wrong, and Chuko explains that her store is closed for the day because all of her merchandise was stolen. The trio agree to help find the thief.
Chuko later runs into the trio while they are searching for their stolen Swirl Console. Chuko thanks them for helping catch the theif with coupons for her store. IF asks her to give them to B-Sha instead, since she caught the theif, so Chuko decides to prepare a seperate gift for her. The trio ask Chuko if she has seen the Swirl Console, and she tells them that a ninja-looking robot had it.
She later finds B-Sha, but B-Sha thinks Chuko is a monster and get scared. Chuko explains that Neptune told her how B-Sha caught the theif, and now Chuko wants to give her thanks. Chuko suggests that she could help B-Sha with her fear of monsters. Warechu suddenly appears, being chased by Kurome Ankokuboshi. Disappointed that Warechu doesn't want to see any of her dreams, Kurome turns her attention to Chuko and B-Sha.
When Neptune, IF, Compa, and Steamax return to the city being destroyed, Chuko flashes back to show what Kurome did. Kurome tried to turn Chuko into a monster, but Warechu shoved Chuko aside and got transformed instead. She then used her powers to make B-Sha view everything as a monster, which now sends her into a destructive rage.
After the commotion that Kurome caused settled down, Chuko hired B-Sha at her store. Chuko also started visiting Warechu every day and bringing him official games in hopes that hesstops pirating.
