A web novel writer with a depressing life, one day Enzo mysteriously acquired the Evil Lust World Travel System that allowed him to travel through space-time and into the different worlds of fiction.

Enzo's only task was to fuck all the important and beautiful women in those fictional works with his evil schemes to obtain rewards and travel to more worlds.

Say no to the life in warhammer 40k
After getting a second chance in the wrong universe—one where hope was a fool’s dream—Luthar, a low-ranked Tech-Priest with no grand destiny, refused to accept his fate. The moment he found a way to escape, he took it without hesitation.

Now in a world where gods walk among mortals, Luthar is armed with forbidden knowledge and technology beyond comprehension. He has no desire to be a hero—only to carve out a place where he truly belongs.

Now onto the synopsis:

I died in a fire tragically, not reaching the full potential of my life.

Thankfully a kind goddess reconstructed my body and transported me into a new world to start my new life.

But wait... What's with this new world?

"Gurararara"

Isn't that the old man Whitebeard fighting the monsters coming out of the gates?

"I am Jiraya, the great Toad Sage of mount Myoboku!!"

*Bam*

"Just stop it already, and let's get this over with"

Isn't that Ero Senin Jiraya on top of his frog summon? And isn't that Tsunade who hit him on the head?

"I am here!"

What's with that heavily muscled macho-looking man and his white teeth? isn't that All Might?

Goddess, just where the hell have you sent me?
And what's with this hentai ability you gave me? Can that even help me here?

Heroines, watch out, here I come!

A/N: Hentai ability; It means this will have an erotic theme going for it. The story revolves around superheroes(Various anime characters: Whitebeard, Tsunade, and so on), the mc getting stronger, the world and its various plots, but also about his sexual journey which will be quite detailed. Those chapters will be tagged +18, so you can skip them, but as you read in the synopsis, his ability is related to that, so the smut will always be brought back into the picture. His ability is similar to the dual cultivation techniques in Chinese novels just to paint a picture of what's in store. But there will be no cultivation BS like realms and stuff. Well, read and see for your own.

If this isn't your cup of tea, consider this an advanced heads-up to not get disappointed.
