Asa is a 16 year old girl with two black haired twin-tails that she sometimes wears down.

Asa doesn't cope well with failure or when things don't go her way. Because of past experiences she is extremely afraid of making mistakes. Once she does make a mistake she usually gets very angry blaming everyone around her except herself.

She’s a loser. A stubborn loser.

She has a crush on Denji, but that’s only because he gives her the validation she craves.

Possibly autistic.
