Warning: is boring AF.
No spoiler review: take every single 2 bits shonen you have ever read ( chosen one MC, dumb as hell, strong as hell, lucky as hell, who eats a lot) add the common waifu (ofc a princess, big boobs that starts stronger than him but soon becomes an eternal damsel in distress), blend everything with a super slow storytelling, trite secondary chars and uninteresting pseudo plot and spice it up with sci-fi elemnts and random stuff from other popular comics (naruto, tdg etc). Add weak sloppy sauce and tada! You got hunter age.
