Before reading the review I'd like to inform you that I've got a gripe with school kid based anime, especially the shonen small kid takes over the world type. No/minimum spoilers will be involved here; I'll start with the bad and end on a good tone.

The protagonist of this anime is a 13 year old boy who has the blood of the supreme leader of all demons, and such, by default he is to become their next leader. Now this is all fine and dandy, but the part I did not like was how they portray this child as an adult using his alter ego as an excuse.
Imagine a council of the most influential big bad yokai in that region listening to a 13 year old boy and following him as their one and only leader. perhaps because this said boy is stronger than any one of them as portrayed a while later in the show, while these "powerful" leaders are just all at his mercy and totally reliable on his for protection.
At some point of them mentions that he's had more power than the supreme leader, but the events of the plot show otherwise, and in the most insulting of manners.

Aside from my why are all anime about school kids pet-peeve, the main battles in this show just felt lack luster, the build-up takes longer than needed with the only constant being that the climax is underwhelming, sometimes so much that it's just sad. In addition to that, throughout the show, many fights have been put off for barely any reason, the bad guys keep running away, but the protagonist and his allies just sit there and look, at more than one point in the anime there's also that Power Ranger "I'll just sit here and watch as my opponent powers up while I do nothing" moments, which just makes me scream WHY!?

In addition to that, have ever played a game with max stealth skills where you crouch in front of an enemy and suddenly you're invisible? Well, some moments of this show gave similar vibes, where half a dozen standing guard still can't see the enemy approaching or running away.

And don't get me started on those "Oh, I forgot I was actually strong" Cliche moments where characters have and the next moment you know, the fight is over in one hit.

The GOOD:
It's surprisingly entertaining. If you're looking for something lighthearted and chill to watch, then this is for you. The innocence in this one is just nice, if you've watched 'Natsume yuujinchou' then you'll know what kind of vibes this one offers. The hilarity and peace in the children's and the yokai's everyday life is just heartwarming. I loved every moment of it. Character development is slow, but it's there, and it's nice to see them progress into realising that life is not all black or white.

I liked how many characters had a personality of their own, this part was well done in my opinion, as the plot continues, you see more sides of every character's personality. Not the most detailed or fleshed out, but just enough, it's there and it's likeable.

The Art is just beautiful, The variety of the Yokai in the mansion just leaves me astounded every time, and each of them are interesting in their own way, each of them given a time in the spotlight showing the different aspects of life in the mansion. The interactions they've got which each other, the sense of home that they've created, it all gives a sense of belonging that was well portrayed.

Overall I think this is an enjoyable show, kept me wanting to know what'll happen next, and didn't feel like a slug to go through, despite it being somewhat childish and wishy washy with many things that barely make any sense. If you want something lighthearted with comedy, romance, and some action to watch, then this is the show. If you're looking for something well written and deep, then look elsewhere, you lose nothing by skipping on this one.
