Ep. 6: Bernard passa por alteração de memória enquanto Suzanna se demite devido à rejeição do sistema e ao medo do Ghoul.

6

Bernard undergoes memory altering, but the cadets are only sworn to secrecy, since only Misaki had a face-to-face encounter with the Ghoul. Despite this, they now know the true threat of their enemy. Kotoko is put back together and the training pace is increased, with Suzanna selected as the primary candidate. Her mind rejects the Integral System, the neural sensor interface used to overcome the effects of the Quantum Core, and this setback plus her fear of the Ghoul prompt her to quit and follow her true calling as an engineer. With two years of memory wiped, including her memories of the other cadets, Suzanna is released from service. (Source: Wikipedia)
