Its target audience are most likely children or jung teens but if you get some episodes in its still enjoyable. If know that you have some tolerance for not so serious storys go for it if seinen is your most liked gerne I woun't recommend it too you. It also starts very mediocre like most shounen but I think it will get better with time. At the beginning I didn't liked the characters but that changed over time. Its still ongoing and will have more that 20 episodes if you hate to only watch 12 before a series ends. Animes/Series that are similar would be Fariy Tail, Wakfu,or Black Clover but it still has its own traits.
