She Professed Herself Pupil Of Wise Man GN Vol 03 (MR)

Sakimori Kagami has awoken in the world of Arch Earth Online, a VRMMORPG he's been playing intensely for a long time. The catch? He made some adjustments to his character when he last logged on, which he thought he hadn't saved. Instead of his normal avatar of an old, bearded sorcerer, he's in the body of a young woman! Now he must convince the people of this world that he - she - is a pupil of the wiseman who vanished without a trace thirty years ago.
