Your swordwork is very admirable, Peko-san! I do not want to distract you from that practice, but I will be glad to teach you if you wish to expand your abilities! [He offers a thumbs up.]

I have only been teaching beginners as long as I've been in this world, aside from a few times in the past when I helped students at the academy. I believe that I am getting fairly good at it! [The fact that he doesn't mention any students having to be sent to intensive care or anything might be enough of an answer.]
