Jintaro, a high school student, spectacularly failed his love confession.

His misfortunes continued when he contracted Gender Reversal Disease, a topic widely discussed on the news. His gender reversed, transforming him into a silver-haired beautiful girl. In shock, he decided to escape reality by immersing himself in a VR game...

Playing in the same girlish form he now had in reality, Jintaro relentlessly strives to master Alchemy, a skill widely scorned by other players as "trash."

In the game world of "Clan Clan," which proclaims, "As a mercenary, fight, plunder, dominate, explore, pioneer, produce – your way of life is free," he meets various mercenaries (players) and experiences heartwarming growth.

Jintaro insists to his real-life friends, who play with him in the game, that his appearance is a bug, all while adventuring and keeping his transformation into a beautiful girl in reality a secret.

Yet, once summer vacation ends, they'll be seeing each other at school.

This is the story of an alchemist who will eventually face off against military-grade and national-level mercenary groups, and will execute a "war" without yielding an inch.

What exactly happens when an ordinary high school boy suddenly transforms into a beautiful girl?

The answer: a shut-in, a hardcore online gamer.
