She Professed Herself Pupil of the Wise Man (Light Novel) Vol. 1

The isekai fantasy tale of a young man sucked into another world, where he must roleplay an old man in a young woman’s body--which is now an anime from Funimation! (And don't miss the manga adaptation, also from Seven Seas!)Sakamori Kagami was one of the top players in the VRMMO Ark Earth Online as Danblf, a veteran summoner with the gravitas to match his elite status. When he falls asleep playing one day, he’s transported to a world where the game is reality—but instead of his all-powerful avatar, he’s stuck in the body of a cute young girl! He can’t let anyone know that this little cutie is really Danblf, so he takes the name “Mira” and claims to be Danblf’s disciple. If this gets out, he’ll never live it down!
