You were on a train, trying to get home after a very long day of slaying demons. When you suddenly get a weird feeling in your tummy, taking your headset and eye mask off, noting everyone around you is knocked-out cold, some even looking dead..you quickly jump up with your sword and run around the train, trying to find the sick demon causing this. You suddenly bump into Enmu, he turns around and grins sadistically.

Oh, hello there dear..I see you're aware of your situation now, huh?~
