Fatality
Guilty conciousness:
From what I understand, there is some kind of dark project going on that implies using the bodies of missing esper and using them within these machines.
Truly a foreshadowing to the FIVER_Over series of technology. The body Accelerator found was a Level 2 Pyrokinesis esper known as Hasami.
Whilte talking with Yomikawa he says isn't his problem and after returning to his room at the hospital meets with the ninja(?) girl again.
Accelerator was easy going but just hearing Last Order from her was like telling him STFU
