C'mon people, the MC alone makes this better than most reincarnation stories. for starters, he has the common sense of an educated adult person who has reincarnated, instead of his mental age degrading to the level of a mentally disabled dolphin. Also he uses his past experiences and knowledge to make sound, practical decisions, unlike other MCs who pull out contrived modern day ex machinas. The best contrast I can think of is comparing to this ongoing manga.

Thank christ most of people on this site can back up their disgruntlement about how stupid it is to have a reincarnated adult and then immediately have the MC act like an actual child.
I get that he is now OP bc Japan has a weird fixation on swords, but like so is the super majority of all characters in this genera, I can easily give this a pass because his attitude isn't one of being a dense mofo or being an absolute beta cuck.
