The demon army wages war to conquer the foolish and ignorant human race.

Due to a demon lord drunk on ambition and an incompetent, brutal king, humanity has been driven to the very brink of annihilation.

The war tilts decisively toward demonic victory.

Now, humanity makes its desperate last stand at Ironhold Fortress, their final bastion.

Guest, a demon general, has single-handedly slaughtered every human on the battlefield and prepares for a final confrontation with Cecilia, the last remaining hero who commands time magic.

On the desolate battlefield covered in cold, lifeless corpses, only Guest and Cecilia remain.

If I can just stop you... If I can just protect my homeland...!

Cecilia, the Hero of Time, casts her ultimate spell: the Möbius Loop.

Even if you tear me apart and slaughter me hundreds of times... You'll be trapped in this endless cycle of time.

But in that instant, time rewinds to before their battle began.

I told you... ugh... hah... hah... Even if I die, I'll keep challenging you. Until you're the one who dies...!
