MC transmigrate in a world where there are only people with true M personality. Now as the only S in the world, he live as he want.

This Earth was in a different dimension from the Earth we live in roughly 500 years ago…

During the Middle Ages, there was a time when many people were killed and injured in wars everywhere in the world.

Among those people was one scientist.

Nowell Piece

This scientist, who hated fighting and loved peace, was constantly thinking about how to eliminate war and fighting in the world.

After 10 years of thinking, he came to one conclusion.

“If everyone becomes an M (masochist), they will hate fighting!”

This scientist, who truly believed in this crazy conclusion drawn over a period of 10 years, set out to stop the world’s wars.

Then he began to develop a drug that would turn people into true M, and after three years of research, it was finally created.

Then, this medicine was made into a gas and secretly spread all over the world, eventually spreading to everyone in the world within a year.

He succeeded in administering this drug.

Of course, Nowell Peace, who did this illegally, was eventually put to death, but...

According to his will, all people in the world, regardless of gender, have become M, and the newly born generation has also become M.

The war has stopped.

And the world continued to develop, and after about 500 years, it developed into the modern society we know.

With a few side effects…
