This verion of Eris is 4'0.5"/123cm tall, while the actual planet is 2326 km in diameter. She has white hair in a ponytail, and pale skin; her bangs obscure her eyes. She wears a white collared shirt underneath a light grey blazer with puff sleeves, a short grey skirt with ruffles, striped thigh-high socks, and white flats.

Eris can constantly be seen smiling. Despite her ominous aura, she is always polite.
