Hugh Pnosis is a young boy burdened with the memories of his past life as an overworked corporate drone. All he wants in this new world is to live a carefree, easygoing life. However, the power he’s granted is the "Brainwashing" skill... an ability that allows him to absolutely dominate anyone he chooses!

Without the guts to even entertain thoughts like, "I'll brainwash beautiful women and build a harem!", Hugh resolves to never abuse his terrifying power and vows to keep it an absolute secret.

But he soon discovers a completely broken, cheat-level loophole: by casting on himself, he can freely rewrite and swap out his own skills at will?!
