• Ability Points her sword toward the sky, charges it for a long time, and then drops dozens of white supernovas to attack. If the charge is fully successful, she drops a massive white supernova at the end (the destructive power is immense, and everyone hates it because the flash and sound upon impact are extremely loud...).

It seems like a decommissioned dangerous weapon or experimental subject created through experiments... But aside from saying strange things, it acts a bit ditzy, causes no harm, and even has a cute side, so the housemates picked it up and are raising it like a pet.

It responds to being called "Fraud."

It possesses a green sword called "Fake Chartreuse Periastron" with a rainbow-colored orb embedded in the center. It has the same model as the "Chartreuse Periastron" sword, but it's just a toy and has nothing special about it...
