Shiraishi Asa transmigrated into the anime world as a male succubus (incubus) and awakened a Sign-In System. But why are all the powers he signs in for Hentai Powers?! Hypnosis Series; Time Stop Series; Tentacle Series; X-Ray Vision Series, Panty Note (based on Death Note), Lewd-gan (based on Sharingan)... “What even are all these things?!” As an incubus shota, Shiraishi Asa has to constantly watch out for the covetous eyes of Monsters, Ghouls, and Demons. And he still has to navigate relationships with both young ladies and married women. “Mrs. Yuigahama, I really must go home, or else Mrs. Yukinoshita is going to get angry…” “Mai-oneechan, I’m still too young; I don’t think I can handle a couples scene…” “Tohsaka-oneesan, already time for more reinforcement? Saber needs some too…” ———————————— PATREON LINK: https://www.patreon.com/primaldemon 50+ advance chapters!

Transported into the Marvel Universe, I find myself reborn as a powerful financial tycoon — determined to become a wholesome capitalist radiating positivity and good vibes… That was the plan, anyway. Until Hawk met Aunt May — the MCU version — no longer the shy young woman of her early years, but a graceful, alluring beauty in her thirties, with the warmth of experience and the elegance of maturity… and a widow, no less. In that moment, Hawk made up his mind: he had to take Peter Parker in — as his nephew, of course. —————————— NOTE: This fanfic includes crossover elements, featuring characters from outside the Marvel universe — such as the Ninja Turtles, John Wick, Cipher from Fast & Furious, the witches from The Witch (Korean film), various Chinese & Korean TV series characters, and even real-world figures like Christina Aguilera, Miranda Kerr, and the Kardashians. Most are female for the harem, though some, like Shredder and Krang from the Ninja Turtles, are exceptions. —————————— PATREON LINK: https://www.patreon.com/primaldemon

After a cataclysmic final battle against the Dragon King Acnologia, Victor Dreyar, a powerful wizard of the Fairy Tail Guild, is torn from his world and thrust into another: the United Kingdom of the Harry Potter universe. Here, magic is no longer a complex craft of runes and circles, but a system bound by wands, incantations, and spoken spells. Victor, a master of intricate magic circles and ancient runic spells, soon finds that his art clashes with the subjective, intent-driven magic of this new world. As he navigates this unfamiliar reality, Victor’s unique abilities, such as weaving crimson runes to summon Fiendfyre and inscribing deathly green sigils for the Killing Curse, draw the eyes of the world’s most powerful figures, from the enigmatic Dumbledore to the dark and calculating Voldemort. With the weight of two worlds upon his shoulders, Victor must face a defining question: will he become a force of transformation, heralding a new era of magic, or will his power tip this world into a darkness deeper than it has ever known? Follow Victor Dreyar as he forges a new legend in a realm of wizards, bending the very rules of magic to his will, and carving his name into the annals of magical history. ------------------------------- PATREON LINK: https://www.patreon.com/primaldemon 50+ advance chapters!

The skylark, a bird known for its ability to sing while flying, has long been regarded as a symbol of "freedom and peace." I was born into the prestigious Senju clan in the shinobi world, and my ojiisan, Senju Tobirama, the "Shinobi World's Fastest," named me Senju Hibari. I was the fledgling of the Senju family. Actually, all of this was an accident. My ride was originally supposed to take me to the neighboring world of One Piece, but the driver took a wrong turn, and that's how I ended up in this world. Fortunately, this world is quite interesting. When I have nothing to do, I can research Kinjutsu with my Ojiisan. I can also drag my good friend, Orochimaru, along to tinker with all sorts of bizarre scientific experiments. And whenever I have a moment, I can even discuss the creation of "Paradise Series" novels with the future Toad Sage. Life is pretty good. As for whether I have a cheat ability? Isn't that obvious? How could I, as a protagonist, not have the standard equipment? I could... ------------------------------- PATREON LINK: https://www.patreon.com/primaldemon 100+ advance chapters!

After unexpectedly crossing over into the world of Pokémon, Maki found himself in a position where he could have lived a carefree life as a wealthy second-generation heir. Instead, he was forced to become an undercover agent for the Pokémon League. Maki looked at the Elite Four member in front of him with sincere eyes and said, “There’s a secret I’ve never told you.
