The strongest Hero in history, Nakamoto Keisuke.

He was summoned to another world in the spring at the age of fifteen years old, and when he successfully defeated The Demon King, he was already thirty-two years old. He had finished his role in another world and returned to Japan, but the reality that had been waiting for him was, “Middle school graduate with seventeen years of blank period” label. He couldn’t find a decent job and had no choice but to spend his days working part-time.

Before such a Nakamoto, a beautiful girl who self-proclaimed had come to return the favor, appeared. “I’m the reward for Hero who had defeated Demon King”, said Angelica, a girl who came from another world that persistently tempted Nakamoto to make her his wife. Together with a high school girl who looks like Elsa, his beloved girl that he lost in another world, Nakamoto with his cheats skills got caught in a harem life.

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!

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”
