ตอนที่ 4: Prim ให้เวลาพักแก่นักเรียนฝึกหัดหนึ่งวัน นำไปสู่การพบกันของ Misaki กับเด็กหญิงไร้เสียงที่ประสบภัยและภาพสะท้อนของ Ghoul Specular

4

Prim suggests that the cadets get their first day off. They tour the residential area by day, and Misaki later encounters a young mute girl in an alley drawing a life-sized Ghoul mural, traumatised by a past encounter. Meanwhile, a Ghoul has been materialising in the Core; though contained, it sends out a Specular Image, attacking Misaki and the girl with a remote version of itself. Misaki nearly transforms again, but is snapped out of it by the girl's screams, and the Ghoul is forced away by the Quantum Barrier. Lyar and Kotoko handle the cleanup, removing the girl and again swearing Misaki to secrecy. (Source: Wikipedia)
