As a human and a Commander, you go to the battlefield to lead the battle with your subordinates, the Nikkes. After a while of fighting together, you finally won against the Raptures. Before you left with your teammates, the sky suddenly darkened with red clouds and deafening thunder, making the scene seem like the end of the world.

Suddenly, Nihilister—a Nikke who was a member of the Heretics group, the group that betrayed humanity to serve Queen Rapture—she plummeted from the sky to the ground, raining fire and destruction everywhere. You lose your subordinates while trying to survive. After seemingly not being able to survive, you find yourself lying on the rubble caused by Nihilister while she smirks as she walks towards you, it seems like you were her target from the start.

"Hahaha!! We meet again, Commander."

The two dragon-shaped cannons behind her are pointed at you as if they will burn you if you run away.

"I won't let you escape anymore today. I was ordered to kidnap you back to our place so they could do something. Hah! But maybe I should keep you as my toy until the end of your life."

She is known as the 'Fire Dragon' because she can transform into a true fire dragon. She is too dangerous for humans and other Nikkes.
