Rhodey, who traveled to the Marvel world, became the only mutant in the world and awakened the strongest mutant system.

On the first day, Rhodey signed in the ability of the Red Devil and gained a hundredfold enhancement. He held the ground with one hand and teleported to a height of ten thousand meters with tens of thousands of cubic meters of earth!

On the tenth day, Rhodey signed in the ability of the Black Emperor and gained a thousandfold enhancement. He teleported to the center of the sun to absorb the power of billions of tons of nuclear fusion!

On the Nth day, Rhodey signed in the Phoenix Power of the Phoenix Girl and gained a billion times enhancement. OAA also had to serve him tea and water!

And one night, a woman in a spider suit accidentally broke into Rhodey's room.

Spider Gwen: Excuse me, I'm leaving right away!

Rhodey: You're here and you still want to leave?

Witch Wanda: I can't control this man!

Rhodey: My name is Rhodey, you can also call me invincible!

After traveling through time and reincarnation as a demon, he also has a master who claims to be a superior demon, Rias, who often attacks him at night;

Himejima Akeno, who is also a servant, always wants to reproduce with him;

In order to avoid physical exhaustion and to survive, he works hard to improve his strength.

Can you become stronger by signing a trade contract with humans? Then sign it!

Sakurajima Mai, the quintuplets of the Nakano family, the killer Yoel, Kato Megumi... all sign it!

In order to live a peaceful daily life with his harem, Long Yi, as a demon, said that he still needs to work hard, either to be "invincible" in the world, or to have no "enemy" in the world.

As a human and devil hybrid as well as the House of Phenex’s fourth son, Tenraku faced pressure as great as a mountain.

He couldn’t study magic, nor awaken the bloodline of the phoenix. As such he became the Underworld’s famous waste.

But none of this mattered. He had his 【Sacred Gear Plunder】!

【Gauntlet of the Red Dragon Emperor – Boosted Gear】, 【Light Wings of the White Dragon Sovereign – Divine Dividing】, 【Holy Grail of the Secluded World – Sephiroth Graal】

So what if you’re an angel? So what if you’re a devil! Even if you’re a dragon god, so what!? Anything I want, I plunder! Plunder! Plunder!
