Hanao Chiaki is a child esper that was imprisoned and forced to fight in the "Esper Underground Arena". She is a fan of Rinka Urushiba and after meeting her in the arena she befriends her.
Chiaki is a child a little chubby with long messy hair and freckles. She is seen wearing a long frilly dress along with a matching hat.
Drowsiness: Chiaki, by the Glowing Fish, has been given the ability to make any person that look into her eyes in the radius of three meter feel an unbearable lethargy, making them completely unable to move and vulnerable to attacks. However if the target doesn't make eye contact she cannot use her powers.
- Her appearance is definitely based on the horror icon Chucky from the movie Child's Play, and even her surname suggest it.
