When being asked if you regret past choices what would you respond with? This is the question Tora Morikowa is trying to answer as he ventures through his new job duties as head warden at The international Science anomaly Containment Facility or the T.I.S.A.C.F. for short . What he dosen't know going in is that there is no going out. But what he doesn't know won't kill him........right?
