Manga Hunter here. I planned to wait until I got home to say this, but I found another light novel that I got into.
Sword Saint’s Disciple by: Nikaido the wind
When he was reincarnated into a different world, he had turned into a woman. Furthermore, when her parents died in a disaster caused by a demon attack, an elderly man saved and brought her up. That man was a former knight of the Kingdom who was once renowned as Sword Saint. Time passed, and a letter of summons from the Kingdom arrived for her Sword Saint Grandfather – who have retired deep in the countryside’s mountains for some reason. She then went to the Royal Capital as a representative for her Grandfather who hurt his lower back, in order to pay back his kindness even a little.
This is an story of the strongest female swordsman, trained by the Sword Saint himself, as she goes on an adventure in an alternate world.
(summary from Lost in Translation)
It is another gender bender story, but it doesn’t focus too much on it based on the chapters I have already read and I am starting to like one of the characters introduced. He doesn’t seem important so far, but his reactions to the main character after first meeting her is too adorable. Some of you might enjoy it as well. As always, please support the creator of this work and the translators when you can.
