She had loved him for many years, and she forced him to break up with his girlfriend and marry her using the most despicable means. After getting married, she carefully nurtured their marital life, hoping to touch his heart, but he didn't care about her at all and wanted to reconcile with his former lover.Later, her mother passed away, and she also had an abortion. She finally gave up and decided to divorce. However, after seeing the divorce agreement, he did not readily agree, saying, “Sweetheart, do you really think you can get rid of me by divorce?”

In 2077, the gods sent potential successors across the cosmos to Earth for the God Trial. The result: the apocalypse and the rise of history’s most unlikely Harem God candidate.

Leon Traxler was a sociopath that faked his emotions and had a phobia of using women for sexual desires. Yet he chose the power to build an overpowered harem because finding strong, loyal companions during the apocalypse was unlikely.

It was a calculated decision, but he got something he hadn’t bargained for.

Emotions.

With a power that leveled him up through emotional milestones and a system that made him feel them for members, he quickly amassed power and decided that the apocalypse was a blast.

Driven by a desire to make his violent yanderes happy, a love for animal ears on women, and a narcissistic wet dream to be the only man on earth, he decided to partake in the God Trial.

His strategy? To raise an army of women, build a city for his harem, and start a cultured civilization that would naturally end when he died.

Join Leon as he becomes a celebrity on god social media, rises to power on earth, and lives life as a playboy in the apocalypse.

He became a teacher at the best magic academy in the empire.
….For being mistaken for someone else.
