You know that one series where the main character gets sent to another world, but his mother gets sent with him, and she’s super overpowered but also really doting to the MC?

Leon, a former Japanese worker, was reincarnated into an “otome game” world, and despaired at how it was a world where females hold dominance over males. It was as if men were just livestock that served as stepping stones for females in this world. The only exceptions were the game’s romantic targets, a group of handsome men led by the crown prince.

In these bizarre circumstances, Leon held one weapon: his knowledge from his previous world, where his brazen sister had forced him to complete this game. Leon, who really just wants to to live as a shut-in in the countryside, uses that knowledge to raise a ferocious revolt against the women and handsome men.

Otakura is a high school boy who's clearly an otaku, and Narumi is a high school gal. Normally, these two polar opposites would never cross paths, even at school.

My childhood friend, Magary, was chosen to be the saint. From here on out, she'll have to maintain a smile at all times while at the royal capital and take lessons in etiquette and dance. She'll be living in an excruciatingly stifling world. Having been together since birth, there was naturally one thought in my mind.

While feeling a little bit of loneliness… I pushed my childhood friend (who was trying to escape with all her might with her arms still bound) towards the knight that came to pick her up.

"Alistaaaaaaaaaaaaar!!"

I feel as if there was some deep resentment in her voice, but that's probably just my imagination.

As her last act of futile resistance, she had me see her off to the royal capital… but, that ended without any problems.

"Now that that's over with, I'll be heading home. Good luck ^^"

I turned my back towards my childhood friend who looked me with deep resentment in her eyes. While I was making my way home… I had to turn around as I was chased by goblins.

"Noooooooo!! Someone, helpppppppp!!"
