I love the MC being a teacher that let's his disciples go through trials. The story is a tad hard to follow but stories that deal with time travel usually are like that. Logically the story doesn't make much sense but its still a solid read. The art is phenomenal too. The only complaint I have is the lack of male characters. Literally every character is female except the MC and cannon fodder. Luckily the romance is one sided for the MC otherwise his harem would be huge.
