Maids VS Apocalypse - Chapter 15: Countdown.

-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.

I’ll just go there and become the top student. No big deal.”

“This is the system? This is my trump card? Why did you only give it to me after I died?” Lu Qing crossed over to the cultivation world and spent 200 years to become a Golden Core cultivator. He married, had children, and created a clan.

He only activated the “Clan Development System” after he died from serious injuries. [Spiritual Root Enhancement], [Resource Scouting], [Pure-yang Body]… Which option do you want?

I’ll give it all to you! I truly am your ancestor. Listen to me and I’ll take you to the skies!
