...[Inside an underground basement]“You are going to die for nothing, hahahaha,” the old man's voice thundered through the room, sending chills down my spine.Step.With a swift and ruthless motion, he lunged forward, his sword slicing through the air and slashing my throat, crimson droplets staining the darkness.“We'll see,” I whispered defiantly, my final words escaping as a mere breath against the impending darkness.Slowly, inexorably, my consciousness slipped away, and I descended into a deep, unfathomable slumber.“Huh!?” My eyes fluttered open, and I found myself seated in a bustling tavern, the air thick with laughter and the clinking of glasses.In front of me stood a captivating lady, her beauty juxtaposed with an angry furrow upon her brow, threatening to shatter the harmony of the jovial scene.“Don't follow me around!” Her words pierced the air like shards of ice, the intensity of her emotions palpable as she cast a resentful glare in my direction, before swiftly departing from the tavern....Am I trapped within the confines of a game?

-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.

He Bai won the lottery, became rich, and reached the pinnacle of life. Then, he inadvertently took a picture of the Film Emperor Di Qiuhe being killed. And after reporting this case to the police, he was reborn in a midst of confusion.

He Bai: I don’t have any horrible relatives to abuse. Why was I reborn?

Di Qiuhe: But I do.

He Bai: I also haven’t been betrayed or harmed by anyone. Why was I reborn?

Di Qiuhe: But I have.

He Bai: I just want to have some money to live freely and eat well. I already achieved that goal, so why was I reborn?

Di Qiuhe: I have money, but don’t live freely or well.

He Bai angrily flips the table: So what’s the use of my rebirth! Just to make me suffer again?!

Di Qiuhe (Holding and Touching He Bai): Be my lover, you’re only responsible for eating “lollipops,” you won’t eat any bitterness.

He Bai: Leave!

So basically, this is a sweet story of a naive and cute person who goes back to the past, flaps his little butterfly wings, and helps the man who used to be last life’s big Film Emperor, but in this life, is still a miserable Great Devil King, to walk towards the pinnacle of life (while also dragging someone home)!
