She Professed Herself Pupil of the Wise Man (Manga) 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 original light novels, also from Seven Seas!)

Sakamori Kagami has awakened in the world of Ark Earth Online, a game he plays religiously. The catch? Instead of his normal avatar–an old, bearded sorcerer–he finds himself in the body of a girl! Now he must convince the people of this world that he–she–is a pupil of the legendary wise man who vanished without a trace thirty years ago.
