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.

Witness the rise of one young man who, with the help of his childhood friend, will face adversity, forge new bonds of love and friendship, and gain the strength needed to protect his loved ones and find meaning in his life.

Rise of the Guild Master

★ 4.5

PunishedKom

The Guild Master of Dewhurst has had a rough life. After many years of failure he rises to face his destiny and transform his decrepit Adventurer's Guild into the greatest Guild in all the realms. How? By filling it up with cute female adventurers who get powered up from making love to him, of course.

Using nothing but his massive intellect, a sharp sense for business, a pair of magic eyes and a dick blessed by the Goddess herself, he'll transform a growing harem of misfits warriors into a team strong enough to defeat the Demon Lord... If the over the top town of Dewhurst doesn't kill them first, that is.

Is it wrong to make bonds in a dungeon?

Ascenderpalgarist

This is a story about a young man who was left to die on the roadside. but this was not the end of his existence, but a beginning of what is yet to come.
he will be reborn in a world where gods walk among mortals. where monsters are not the only threat.
will he be able to live a life and find a purpose that is worth living or dying for?

Note: This isn't a story where the MC chases every woman, nor does every girl he talks to fall for him. Relationships will have depth and meaning(at least I will try to give depth)—he’ll have to earn their love. He will be stronger than an adventurer at his level, but He won’t start as someone who is too OP, but his growth will outpace even Bell’s. If you're here for real development—both in strength and emotion—then welcome aboard.

As of now, I plan to include only Ryuu, Riveria, Ais, and Asfi and focus on them. In the future, I might add some other girls in the harem.

every chapter will be between 1000 words to 3000 words.
