Gokusai Amazora

Gokusai Amazora (獄彩雨空) is a character introduced in the sidestory Toaru Majutsu no Index SS: Biohacker Arc. She is a teenage girl and the third of the three Gokusai sisters.

Etymology
Amazora's surname Gokusai may be translated from Japanese as "painted prison". The three Gokusai sisters share a pattern where each sister has a first name with a nature-based character; in Amazora's case, it is the character for "sky".

Appearance
More often than not, Amazora is described in the Biohacker SS as a girl 'under 130cm with obviously bleached hair' and who 'wears clothes that makes herself look like she's older than she actually is'.
