I find this series very entertaining and always find myself fired up when everyone gets in that mode of the whole my rivals are pushing me to do my best in the manga world.
Nizuma Eji I have to say would be my most favorite out of the manga authors there because well he's a genius at most. Ashirogi is also my favorite in the series. I've watched all three seasons and don't want to see this series end.
I recommend people watch it.
