The main character is reborn as a character from a game he played in his previous life. This character falls into ruin along with the villainess, spending the last of their years together. A man named Kururi Helan.

In the beautiful comic world, superheroes are infinitely beautiful.

Mutants who also have super powers are extremely sad.

Lynn came across time and became a student of the Academy of Mutants with the ability to create magic.

Apparatus, Avada Kedavra…

Glacier Spikes, Ember Storms…

God Slayer Magic of Fire, Dragon Slayer Magic of Thunder…

After ten years of accumulation, Lynn has mastered countless splendid and terrifying magics, but he knows very well that it is meaningless for Professor X to let the students act as thugs to save the world in order to allow humans and mutants to coexist peacefully.

The only way to change the living environment of mutants is to increase the right to speak!

Where does the right to speak come from?

Strength is the foundation!

Money is on the left, power is on the right!

So, he approached Professor X and proposed a package plan to establish a mutant consortium and gain power through money:

The first step is to create “Oasis” and create a second world!
