What would you do if you got summoned to another world without your consent?

How about... Getting summoned by a dark cult and at the same time, losing something within you that will make you question if you are still yourself?

Casimir Kismet is just your regular weeb who has a hobby of cosplaying, has a loving adorable little sister, supportive parents, and friends with a common hobby as him.

An ordinary but content life if he must say.

But, not anymore.

Everything changed when he got involved in a disastrous dilemma of getting summoned to another world by a federation of dark cultists and turning him into something he never had imagined he would become. At the same time, he obtained a skill that gave him the ability to copy skills by just seeing them cast. 

Changing his life forever. 

Every coin has two sides, there is no such thing as pure evil or absolute righteousness. And If one is evil or righteous, it cannot be easily recognized. 

But, the real question is, which side would you let come out the most?

His CONQUEST is about to begin.

But before that, let me tell you these fair warnings.

This is not a story of a hero. You have been warned.

Not everything is actually what they seem. Do not be fooled.

And most of all...

Don't show him your skills.
