The Dark Lord Leonis awakens after a thousand years, only to find himself in an unfamiliar world. But that isn't the only change he faces.

Leonis’ platoon attends a commendation ceremony on the SS Hyperion, unaware of the sinister plot to kidnap the Fourth Imperial Princess.

The Void Lord awakens and Leonis discovers an awful truth.

Leonis must defeat the Void Lord by any means necessary, even if it means using the souls of the deceased.

The kidnappers accounted for many things, but they did not account for the interference of the legendary Demon Lord.

What quest could be so important that a hero travels to the future in order to fulfill it? Regardless of her reasons, the group must find the Void Lord before it’s too late.

Humanity has grown in leaps and bounds. If Leonis plans to rebuild his forces, he must first take stock of human military might.

A competition gives Riselia the opportunity to show how much she’s improved. The timing couldn’t be better: the next mission will put everyone’s skills to the test.

Leonis may be a demon lord, but he still has his honor. He will put an end to the invasion, but he must first draw a sword that will test his resolve before he can wield it.

Riselia learns what really happened to her the day she first met Leonis and that makes her worry she can never manifest a Holy Power. That worry is about to be tested.

The students go about their daily lives while Riselia hones her skills as a vampire. However, they are all unaware they are experiencing the calm before the storm.

The city is under attack, forcing everyone on the defensive.
