The story had its exciting moments, but the development of the main character ruined everything. Even after 520 chapters, the main character behaves foolishly, failing to use his space power when necessary, and constantly getting beaten up by others. He still hasn't developed his Aura, which all the other characters have already accomplished. He recklessly engages in death matches all the time, yet there's still no progress in his Aura development. I've decided to stop reading this because I can't push forward anymore.
