I am uncertain about this one. Firstly, the premise does not make much sense, since if there are so many pupils that this master had and became famous in some way, that would have made him famous. If pupils swore into secrecy - than ok, but it does not look to be the case. I am also unsure what's the point of the show in general. Is it going to be a slice-of-life harem, and sword mastery is just a feature? Or is there a plan for some actual plot? Since this is unclear, I will give it a fair chance. Besides the sword master is a bit more relatable than the guy who can buy anything from virtual store.
