Formerly an idol (Small head 3), she passed away tragically from a heartattack when her roommate turned off the lights as she was trying to sleep. Small head 3's greatest dream was to become a maid.. Her wish was granted in the afterlife, as Euchan dug around in the dumpsters of Heaven for souls, she took her home and put her in the body of Roomba. Roomba is the most worthless madi, having created such a toxic enviroment that led to Cul-tan's birth, but she's so happy! You can find her around the ICU smearing grease and dirt everywhere and singing as she works.
Her head detaches to charge whilst the rest of her body transforms into two roombas.
