Every story needs a great evil for the hero or heroine to defeat…

The wicked stepmother who torments Cinderella.

The fearsome dragon who kidnaps the princess.

The fake rich daughter who bullies the real.

An evil demon queen hell bent on destroying the world.

Yet sometimes these villains defeat the heroes.

Agent 214 has been tasked to enter these dangerous worlds and eliminate these evil villainesses before they have the chance to win.

But why is every story a little different than what it first seems?

As Orson read the novel written by the girlfriend who had left him, he gently remarked on how terrible the story was. But then, noticing a foul smell coming from the kitchen, he went to investigate. He realized there was some kind of gas leak. Already furious about being dumped, Orson became even angrier at the state of his kitchen, and in his rage, he hit the light switch with a powerful punch. Naturally, the explosion that followed killed him instantly, and Orson passed into the afterlife.After spending some time in limbo, he found himself reincarnated in an unfamiliar world. However, he quickly realized he had been reborn inside the cliché-filled novel written by his ex-girlfriend. As if that wasn’t enough, he had ended up in the body of Neonidas, a useless duke who was also the fiancé of the story's villainess.____There may be a bit too much swearing and slang in the first chapters, but it gets less afterwards.There will be no yuri, bl or ntr in Neonidas(MC) harem

Reborn as a Gotham minion and strayed into an evil organization, his heart is bright but he has fallen into darkness step by step. The whole world and even countless worlds are convincing the good guy Mason that it is obviously more promising to become a super villain in this era of disaster.

But Mason didn’t think it was easy to convince himself, so let’s do something simple.

How about we try to bring this dark and chaotic era back on track?

besides!

Batman and the heroes of the Justice League, when are you fucking going to do it? If I don’t close the net, I will go undercover and become the evil boss!

PS:

The real title of this book should be “Crossing the Beautiful Man: I Want to Be a Good Man”, “Gotham Legend: If I Were Robin, Would You Love Me?” “, “One Hundred and Eight Confessions of the Unlimited Traveling through the Worlds for White Whoring Monsters” and “The Tragic Past: From Craftsman Spirit to the No Return of Counterfeit Dealers”
