While we say reincarnate, it is more accurate to say he got a new body. In other words, he is as strong as he was in his previous life, with all the memories.
More importantly, when he comes back he decides to go to school and learn about this new world. Also, he wishes to reclaim his place as the demon king. Actually that's the real goal, the school is kinda needed for that.
(Btw because this is an anime, he basically builds a harem along the way. )
I think that's the best i can do without getting too spoliery.
In my opinion, this show is average across the board. That doesn't make it not fun though. The thing has it's far share of memes after all. It also has it's part in this season's waifu wars.
Not for having a good waifu, but a bad one. (I think that's the best way to put it.) For some reason this season people are picking out waifus with bad personalities or something. (None of this is important.)
So far the waifus are his driving factor for actually doing stuff because he's the actual demon king. Getting good grades and performing is something he can do in his sleep.
If you are looking for a simple show to burn time, give this one a shot.
Actually i don't know how much this will be worth watching once the season is over because the community is making it alot more enjoyable.
Watch it anyway.
