Having kids take staring roles in video games/anime is always a pet peeve of mine. I have a lot of experience coaching kids. I know exactly how well they are developed physiologically and psychological at different ages. Even 18 isn't close to being an adult from a sports perspective.

That and listed weights always irk me quite a bit. They always seem completely out to lunch. Typically they are WAY over light to someone of a similar height and build having to meet the physical strains of saving the world-ing.
