The Everyday Life of Good and Evil After Transmigrating into Superman

After learning that he is Superman, the protagonist starts living a life of switching back and forth between Superman and Homelander.

When he wants to fight crime, he becomes the embodiment of justice, Superman.

When he wants to do whatever he likes, he becomes the lawless Homelander.

He thought he could keep living like this forever. After all, he was invincible in this universe and could suppress anything in the world if he wanted to.

But he never expected Kingpin to finish developing the collider, causing superheroes and supervillains from other parallel universes to invade this one from time to time.

Even the Batman Who Laughs showed up in this universe.

Though the Batman Who Laughs was powerful, the protagonist had also gotten stronger through reincarnation.

The King of Hell promised that if the protagonist chose to reincarnate in another world, he would gain extraordinary powers of evolution and learning.

Thanks to that, the protagonist, now Superman, kept growing stronger and stronger. He even used kryptonite to forge a suit of armor specifically for fighting other Supermen who invaded this world.
