Boring, barely coherent plot and no real difficulty for MC, however it's paced so well and drawn so expertly, it manages to be very engaging, addictive and therefore popular. Every boss seems stronger than MC, and when mc is about to be overpowered he reiterates that point, only to just go and defeat them anyway. Just like that. Can't really blame the author: making a comic of this quality probably leaves no time to think of interesting developments past a lot of fancy posturing from very cool adversary characters and cute tail-wagging by the pet-like supporting cast.
