Ibuki Karen has outstanding looks and a genius nature that lets her produce above-average results no matter what she does. While spending her days in a rut, she encounters the VRMMO 'Grimoire Fantasy'. She immerses herself in the full-dive RPG where angels and demons fight over territory, diving into the game as the angel Eve - but. 'This is the limit... from the beginning there was no way I could win, something about me...' Caught in a cunning trap, she becomes a captive of pleasure sex that feels like it will burn out her brain...!? For an honor student like me to be dominated by beast-like carnal instincts... My body and mind eroded, I start fawning over my master.
