What lured me in is the middle aged MC and I find it amazing how almost all his students are high ranking adventurers or officials meanwhile he's a country bumpkin, it makes you think about their dojos history (It would be nice if they were detailed as to why their dojos technique are better than the others) The MC's fighting scenes indeed are a bit lacking but him showing manners that he's aged after every fight is hilarious like example complaining about muscle pains and the way he thinks is more mature and being nonchalant with the girls flirting at him. Overall I enjoyed this, if youwant a mature MC that isn't a big pervert then give this a try. I'll read the manga to know what happens after I'm curious how he will become a well known swordsman and mentor.
