Good shounen anime for what it is. Story from one of the biggest influences in anime/manga Akira Toriyama (May he rest in peace.) Especially recommended for the younger kids to watch. Tanks, guns, and a little blood in the show. Labelled as a comedy but not all that humorous for a mature audience at least. Regardless, as a working adult, the anime as a whole brings a smile to my face.
Art/Animation: Not for everyone. CGI animation which isn't everybody's taste but has a blend of 2d in it. I think it's well animated and the characters look like they were the characters were almost ripped straight from a Toriyama's manga panel. Backgrounds aren't too detailed. The vehicles in the show are really well done.
Characters: Not a very character driven story. Beezlebub is the goku of the series. He's a kid and he is overpowered. Where it really shines is with the Sheriff Rao and his backstory. Not many anime have a clearly older gentleman as a main character. The other character of the trio is just kind of there. Would have been interesting to have a different fiend join the party.
Story: Pretty simple plot. Set in a desert land aka "Sand Land". It's hard to come by water. Sheriff goes out in search of water and teams up with a pair of demons/fiends. After episode 6 is to anime original and I look forward to watching the rest.
