Sword Magician

Ren was always been an average student, only having a single talent, sword talent. His family runs a Kendo Academy, but that did nothing good for him. Ren's method of sword fighting is more of practical than traditional, using sword with only one hand, using agility, speed and reflexes. though its practical its not within rules, resulting him in being cast aside remaining average as ever, he always tried staying by rules but no matter how he tried abandoning practicality always felt wrong affecting his performance. but one day while siting in a park at night a golden sword appeared out of nowhere and pierced his heart and when he woke up he find himself in new world full of magic.
