Hitotsuya

Affiliation: The Round Table
Bug: Caterpillar
Ability: Adaptation - Metamorphosis. Creates a cocoon that automatically adapts the users' body in response to the needs posed by the outer environment, allowing her body to "learn" from threats and come up with a counter. However, this adaptation process takes a relatively long time.

Due to both her very young age and the nature of her bug, she's the most childlike of the participants and isn't really capable of controlling her own powers, nor does she necessarily understand their repercussions.
