MADOUSHI WA HEIBON WO NOZOMU

"No one will capture me!" Mizuki, a grown-up who loves gaming, is suddenly swept away to another world. She resolutely survives by using her inherent grit and magical talent. Then, two useless knights and one particularly kinky knight arrive on the scene. The appearance of so many disappointing hot guys marks the beginning of Mizuki's unprecedented, alternate-dimension life! Her chosen lifestyle involves nothing but "being herself!" This is a meritocratic, alternate-dimension fantasy that features hot guys with sublimely deplorable flaws and a sadistic mage!
