"I'm a cute, mysterious girl who was drawn into this place by a possibly grand fate! As for my name... I'm 'Nobody!'"
White with black tips
Riddles, having fun
Nobody (ノーバディ) is a mysterious girl who lives inside the Phantom Field. She claims to have no memories. In truth, she is Es, or rather the manifestation of the Embryo inside Es's body after Es purged her memories due to falling into despair from watching Freaks kill Touya Kagari and her other friends.
Nobody is a slender, pale young woman with long white hair and bright blue eyes which she nearly always keeps shut. Her hair has black tips and small lavender accents; she also has a singular ahoge shaped like a heart.
She is barely dressed, wearing a small black shawl that is tied with a small ribbon, and black sleeves. She wears white underwear and white tights with small black diamonds on the feet. Nobody also wears black high heels with golden rims.
Nobody is incredibly hyperactive, always cheerful and ever-curious. She is also fairly ditzy, not listening to others and being unaware of social norms (like when she would get way too close to someone) or the ways of the world (such as believing people can die from boredom). However, beneath her façade of happiness she is actually incredibly lonely, which was why she tried so hard to become friends with Me. After reliving Es's memories, Nobody tries to put on a front of accepting being alone forever but is truly in despair from the loneliness.
Powers & Techniques
As the creator of the Phantom Field, Nobody has unique powers over it. She can traverse it freely without collecting Memory Fragments to pass through the barriers between floors and can sense whenever someone entered it. Being the Embryo, she has the power of Phenomenon Intervention but is too weak to use it beyond turning back time after Es created the World of the Tsukuyomi until Me used her Origin of the Grimoire to power the Embryo.
