Not a typical shounen. If you're expecting Naruto-style, you'll be disappointed. The characters are not very likeable. An interesting fact may be that characters are named after various music groups (which can also be considered laziness while inventing names). Animation may not be suitable for everyone, as it consists of mostly pictures (proper animation is rare), also it feels cell-shaded. Covers Part 1 and Part 2 of the manga with 9 episodes focusing on part 1 and the rest focusing on part 2. I liked part 1 more, because I found the protagonist and the main villain more interesting and the ending was surprising to me, unlike part 2.
