Jotaro awakened his Stand at 17 years old, but unexpectedly bound to a bastard system. Under the system's effect, he was forced to go to other worlds. In order to return to his own world, Jotaro had no choice but to complete the tasks issued by the system.Demon Slayer world: “Yare yare, Muzan, there's only one reason you failed, and that is, you pissed me off!”One Piece world: “You bunch of guys, I’ll be the one to judge you!” While violently beating up the Celestial Dragons, Jotaro completed a research paper on sea king-type creatures.Naruto world: “The one judging you is my Stand, Star Platinum!” Star Platinum, the true god of ninjutsu, ultimate hand sign speed. You call yourself the Copy Ninja?Originally, Jotaro only wanted to find a traditional Japanese woman to marry and have children, but he seemed to have underestimated the Joestar bloodline's attraction to women. Unknowingly, the women surrounding him grew more and more, and all willingly.The chatter of lovely women behind him made him extremely annoyed.He suddenly turned around and shouted, “Yakamashi! So annoying! You stinky hags!”[1st World: Demon Slayer2nd World: Tokyo Ghoul3rd World: One Piece4th World: Naruto]

From a caste based high school, bottom-tier Naomi Masatsugu is caught up in a summon of his class to a different world. However, as soon as they arrived the king said, “This guy is unnecessary because he only has clumsy skills ” and it is concluded that he is to be forced to administer the orphanage, which no one wants to do. Unfortunately for the orphanage his skills were cheat skills that cause the girls to cling to him.

In order to “defend” the girls that depend on him, he must operate the orphanage while overcoming the powerful people, authorities, and former classmates that surround him.

After a brutal day on the construction site,Jaxon collapsed onto his cot with nothing but sore muscles, a cheap dinner, and a phone in hand. Out of boredom, he picked up one of those mindless urban web novels—complete with arrogant young masters, all-powerful protagonists, and women falling in love every other chapter.“Who writes this garbage?” he muttered, tossing his phone aside and cursing the story, the characters, and the plot that made no damn sense.Then he woke up inside it.Not as the protagonist.Not even as comic relief.He’s the villain—the arrogant heir of a wealthy family destined to be publicly humiliated, slapped down by the protagonist over and over again.

Rick Rolland didn’t expect to die young while gooning to some peak milf video, and he definitely didn’t expect to wake up in a world of dragons, elves, ancient empires, and magic older than civilization itself.But even worse than death was the cheat ability he received. Right after reincarnating, a small glowing figure floated out of his chest.A tiny chibi old-butler spirit with monocle, mustache, and a permanent irritated look.“Ahem. Welcome to Zorathia, gooner user.”[MATURE AFFINITY SYSTEM ONLINE]“You can only gain EXP by increasing affection with women aged 30 or above. Try not to die… while gooning again because you can have womans now...”Rick froze. Other isekai heroes would kill goblins, slay dragons, or train with legendary swords.But him? He levels up by seducing older women.“Slay goblins? Too simple.Lift a sword? Too mainstream.You, gooner user, must charm experienced ladies until they blush.It builds character and yours is nonexistent.”And just like that, Rick’s life in Zorathia spiraled into chaos.--------------------------------------------------Disclaimer: No NTR and Yuri.
