• Ability She points her sword toward the sky, charges it for a long time, and then drops dozens of white-light supernovas to attack.

It looks 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.
