The last scene
Adela reached out and touched the demon's head. Suddenly, everything returned to normal when she said something. However, the demon retreated while yelling, appearing to be in anguish.
Wilson and Francis averted their eyes; they sensed something had occurred to them but could not pinpoint the cause. Then, suddenly, they noticed the monster screaming. Alfred stopped there, his eyes widening. He was terrified of that awful thing, and they would not keep their daughter's secret any longer.
Adela was there as the imperial knights surrounded the demon. The barrier shattered when the monster struck it while wailing in anguish. People on that side fled. The demon flailed as it landed on the ground, and then it abruptly began to disperse. The body of the monster began to let out a dark vapor. Then it began gradually fading away from that point.
