The story follows the "strongest juvenile delinquent", Oga Tatsumi, a first year in "Ishiyama High" the school for delinquents. One day while sleeping next to a river he sees a man floating down it, he pulls him to shore and the man splits in half revealing a baby boy. This boy is the son of the demon king and he has been chosen as the one to raise it with the baby's demon maid Hilda. The story follows his life with the child and at the delinquent school.
This show is a fun watch. It will entertain you, but don't expect to be blown away by some extraordinary comedy/action/character development/plot twist. It isn't an excellent anime, but its entertaining enough to keep you interested. I will definitely continue to watch this ...
One little problem I'd like to mention though is that a lot of jokes are repeated over and over, to the point that you don't even smile at them anymore. such as
SPOILER BEGINS
baby beel electrocuting oga literally every 3-or-so minutes during the length of the ~25 minute episode - you can count for yourself how repetitive it can get.
SPOILER ENDS
so overall, its not perfect but its good for what it is and should be able to entertain you.
