Chacha

She is the eldest daughter of the Queen of the Kiseichuu and holds the position of princess. However, she is a mutant known as the “cursed child born once every thousand years,” possessing cat-like features while having a human-like appearance. Due to her vulnerability to catnip, she is considered even closer to a cat than to a human. Her characteristic phrase is “nanoda.”

Contrary to ordinary Kiseichuu, who absorb human H-energy, she has the ability to amplify human pheromones. She mainly enhances pheromones by making her bodily fluids contact human skin, and even her severed hair can have the same effect. Furthermore, by biting, she can accelerate pheromone amplification, causing those bitten to enter a “Carnivorous State (Beast Mode)” where they lose their reason and go on a rampage.

She also possesses mimicry abilities, allowing her to disguise herself as a human, a cat, clothing, stuffed animals, and even as a XERO Suit. She is capable of taking over the body of organisms she assimilates, and can mimic their appearance in this state as well.

As a “cursed child,” she was resented by her mother and kept in confinement, but gained her freedom thanks to the help of Kirara Hoshino and Retto Enjō. Afterwards, she begins to travel with Retto and his group. In her confrontation with her mother, she declares her dissolution with the Kiseichuu by proclaiming herself to be an HXEROS. In the first character popularity poll, she ranked 12th with 632 votes.
