Meisa Ichikawa
Meisa Ichikawa is a second-year Coppelion, all of whom are considered defective since they constantly emit neutrons, making Meisa and her peers into walking biohazards that waste living beings through their mere presence, except for other Coppelion. Her special ability allows her to disassemble and reassemble her body at the atomic level. Meisa is working under Dr. Coppelius against Ibara and the others because he promised that he'll find a way to fix her defect. Alongside her best friend Mana, she is a former member of Exploration Unit that went renegade just like the Ozu sisters.
