Nikusa is the Queen of the Void, as she also has an urge to eat food as she is very flirty with others and often feeds others who she considers too small. She also knows BoyFriend and Girlfriend, as she grew quite fond of them with their relationship.

She often befriends people since she is lonely, often with feeding in mind. She is also capable of morphing her own body into various shapes and sizes. As such, she can either change herself to look scary, or simply puff up and look chubby.
