- Description from uukanshu (translated)

In a world filled with abilities and superpowers, Moby Kane, a 16-year-old boy, is an orphan who is living his life with a little too much optimism, trying his best to get by.

Due to him having no ability, he had been bullied and tortured every day. However, for some odd reason, he never complained and always stayed happy no matter what. It was almost unnatural.

On one cruel day of immense pain, he realized that the world is a brutal, unforgiving place, making him regain his lost senses.

In his moment of desperation, a miracle happened.

[ You have unlocked the Demon System ]

Now that Moby has the power to change his cruel destiny, how will he use it to get back at the world that wronged him on the road to becoming the demon lord...

IMPORTANT MESSAGE TO NEW READERS! PLEASE READ!

My first few chapters' writing quality is very bad and lackluster but gets much better as the novel progresses!

Also, the first 5 chaps are kinda similar to vamp system but the story and settings differentiate after that into their own thing past that point! Hope you stick around! :)

Quick note! many people in the world are cruel and almost psychotic but there is a good narrative reason for that, it will be explained later on in the novel I promise! :D

-The well-known characters of your favourite series get into orgy-In a world where anime universes collide, an omnipotent, perverted god known as The Great Weeb Overlord grows bored of endless power fantasies and shonen battles. Instead of another tournament arc, he decides to host the ultimate crossover event—one fueled by raw passion, unfiltered ecchi energy, and the deepest desires of fandom itself.When Kazuya, an average, luckless otaku, is inexplicably summoned as the “Chosen One” to oversee this legendary gathering of flesh, he finds himself surrounded by the most iconic waifus and husbandos of all time—Asuka, Rem, Bulma, Zero Two, Hinata, Erza, Akeno, Saber, Makima, and many more. Even some of the most unexpected faces (yes, even from wholesome anime) are caught in the gravitational pull of this sinful singularity.As the Ultimate Fan Service begins, Kazuya must navigate the chaotic pleasure-fest while avoiding jealous yanderes, tsundere slap-fests, and the terrifying wrath of overpowered shonen protagonists who refuse to share the spotlight. But with reality itself warping under the influence of peak degeneracy, Kazuya soon realizes there may be no escape… and worse—he might actually enjoy it.Will he survive this NSFW isekai experience? Or will he be consumed by the horny abyss?One thing’s for sure—this is not your average anime crossover.
