Kaguya is someone who is narcissistic and haughty, prioritizing being gorgeous over everything else, such as giving the Kitchen Ichinose Alliance extravagant outfits and being charismatic enough to attract fan clubs. Supana’s the only one who isn’t fond of Kaguya.

The conflict arises when Houtaro forgets about Kaguya and calling him out for using Chemies as tools. The reason is that Kaguya wants to reconnect with Houtaro and believes that being gorgeous means attracting attention from enemies, but that means Kaguya can feel lonely, and Houtaro is one of his few meaningful connections.

Houtaro is seen as not considering Kaguya's feelings, but forgetting Kaguya is something outside of his control as it's memory-wipe shenanigans. In addition to using Chemies as finisher weapons, Kaguya also took Hopper1 and Steamliner from Houtaro's Driver without asking for permission to borrow the cards.
