Sayuri

An esper girl who belongs to the esper organization "Synapse". She was kidnapped when she was little and subjected to numerous inhumane experiments at a laboratory researching psi in a certain country. A few years back, she was being used as a weapon by a certain country's military. Her ability is simply psychokinesis, but it is highly powerful, being able to destroy even a battalion of tanks. Due to the countless experiments, she's kind of got a few screws loose. She's cheerful, whimsical and uninhibited, yet extremely brutal. She gets along well with Tachibana, who was also formerly a member of the same army, and they used to hang out often. One day, she suddenly destroyed the laboratory and deserted the army. She was enjoying herself roaming the city and committing massacres whenever she felt like it when she was scouted by Tachibana, who had become a member of Synapse. Likewise, she became an Synapse esper as well.
