To further elaborate on what others said in Japanese culture, the highest levels of the study of the sword are also a philosophical and spiritual pursuit rather than a purely martial one, and given the Japanese word for saint, seijin(聖人) can mean both a saint or sage depending on the context, the title for the highest achievement in swordsmanship being called a sword saint(sage), kensei (剣聖), makes more sense when within that specific cultural and linguistic context.Hmm i do hate the word Swordsaint because saints are peaceful people who tends to be selfless and very helpful to everyone. often do try to heal people, feed the poor and help them on their feet again 100% selfless.
so anyone who uses a sword is kinda different.
so our cool MC is more like a swordmaster. he is SO great with a sword that he is close to be a demigod. Sword medium?
