Sonnet Barge

Sonnet is a 16 year old esper cyborg soldier with silver hair (though it is blue in the OAV) who works as a scout for Talon. Her mother is from Puerto Rico and her father is Caucasian-Russian. She was raised in the slums of New York. When she was about 13 years old, her latent esper abilities began randomly manifesting themselves, causing people to label her a "witch" or a "devil child", and this caused her mother to have to turn to prostitution for money.

She was tricked into believing her mother was going to be killed, which caused her latent esper powers to fully manifest. Because of this, she now works as a scout for Talon, mercilessly hunting down espers such as Lan. Her interaction and blooming friendship with Lan and others at the school, however, has caused her to remember her humanity and she begins to question her loyalties to Talon. She finally learns from Lan's boyfriend Bird what real love is.
