In the part where Shiki and Touko talk for the first time about the spate of suicides, Mikiya is sitting on the couch in front of the television, he appears and disappears between shots.
Shiki fights against the eight ghosts of girls who committed suicide. but by the time of the fight, only six girls had died.
Shiki's left hand is amputated by herself. Much blood gushing enough to cover her clothes and face. In the next shot, her clothes and face are clean.
