Nikku Morioka is a lost space girl hiding from a secret agency that used her for experiments for years after crash-landing on Earth until running away and seeking a home inside of an abandoned mall. She is the main opponent of the mod, where Boyfriend happens upon her hiding spot and they rap battle to solve their dispute. Nikku is a humanoid alien with grayish-white skin, reddish-pink bowl cut hair and large black eyes with three eyelashes along the bottom. She appears to have no neck; her sphere-shaped head floats above her body. She wears sleek navy-blue clothing (which appears as black in some of her sprites), pointed shoes of the same colour with reddish-pink accents and white soles, a red belt and a backwards ball cap which is the same colour as her clothes and has an orange brim and circular insignia. Nikku can float above the ground, seeminly unaffected by gravity. When she sings, the brim and insignia on her ball cap change colour to match that of the note she's singing.
