The story follows the High-schooler Futsu Jintarou, whose confession was rejected by his crush. His misfortune continues, as news of a gender-change disease turns Jintarou into a beautiful silver-haired girl. The shock of it causes him (her) to try to escape from reality by playing the VRMMO, Clan/Clan. His game character Taro uses the same girl's appearance as in the Real and the Alchemy skill, which most players call a trash skill.
He meets lots of fellow adventurers, and becomes stronger within the game world of Clan/Clan’s slogan, ‘When one becomes an adventurer, they can fight, steal, control, explore, invent, create, and do anything as they like’.
He meets a wide variety of adventurers that help him (her) grow, Taro hides what happened to his (her) appearance as a bug to his friends who also play the game, and hides the fact that he (she) had become a girl in real life. When summer break is over, he (she) will have to show their face at school.
This is about one of the best National-class adventurers, the story of the Alchemist who won a war without even taking a single step. When a normal high school student suddenly turns into a beautiful girl, what would they do?
The answer is to that is to become a net-game addict.
