This manga follows the three Demon Kings who find a human child in Hell. The story is rather vague and especially unique, but it's very cute and charming in the way it's presented.
The story starts out rather slow and the development between the Masked King (the main character) and Maris (the kid) is very abrupt and painful. In the beginning, Maris feels like a real brat and the Masked King is completely useless when it comes to taking care of him, but as the author and story grows more and more, it becomes better and better. It becomes very touching the further you read and you can really feel the affection between the characters.
All the side characters are likeable and get some type of development, some even getting chapters with focus on them. The characters are pretty cliched, but a lot of tropes are played with around with (playboy turning into a diligent father, etc.). Some of the other characters, like Lilith and the doctor, barely get developed, but I think that's due to time restrictions.
The art has a very mix of fairly realistic and cute art, with the Demon Kings and gags being drawn in a realistic style, but Maris being draw with the stereotypical cute round face and eyes.
The art just gets better and better the longer you read, but it's definitely not an eyesore in the beginning either.
Overall, I really enjoyed this manga and I think it's great if you like child/adult interactions. Do I think it'll win an award for excellency? Probably not, but that's also okay.
It's mindless, charming family fun and it's perfect for sad days
