Hyper Dimension Neptunia G: The Golden Leaders, Reconstructors of Gamindustri
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 thief with coupons for her store. IF asks her to give them to B-Sha instead, since she caught the thief, so Chuko decides to prepare a separate 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 thief, 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 in the Basilicom every day and bringing him official games in hopes that he stops pirating. However, it is quite clear to everyone that Chuko is there to see Warechu as she has fallen in love with him for saving her.
Heart Dimension Neptunia H: Trilogy Finale: Into Legend
When Nepgear, IF, and Compa come to Chuko's store to recruit B-Sha, Chuko encourages B-Sha to save the captive CPUs. Once B-Sha resolves to help the trio, she asks Chuko if the store would be okay in her absence, given the recent increase in customers. Compa immediately runs off to grab Warechu for the position. Despite Warechu being unqualified (and not wanting to work), Chuko hires him.
Chuko is mentioned by Compa as assisting all of Gamindustri's forces against the monster horde.
A few months have passed since Uzume was resurrected and Chuko yells at Warechu for continually slacking off, telling him to help the customers. Warechu begins to complain about his job, before daydreaming about going on a date with Compa.
Upon seeing this situation, B-Sha suggests Chuko acts nicer to Warechu. Chuko gets flustered upon hearing this, stating she just wants to rehabilitate him as an honest mouse. B-Sha then mentions that Warechu might like Chuko if she acted nicely. This then inspires B-Sha to give her more advice at the cost of 1000 Credits. Chuko is surprised that B-Sha would try to get money from her employer, but is curious to know what will happen, so she deliberately accepts her offer.
