I feel kind of sad for the rider guy.
he's a classic shonen hero, and the public sees it and adores/worships him for that, which is probably why he got the #1 C-spot.
however, he lives in a world that doesn't always reward hard work and determination, so he's bound to get beat up (and die one day), and he won't run away because he's so caught up in 'being a hero'.
and their talk about having to do 'weekly hero duties' that saitama hates? the rider guy loves it, he lives for that shit, he's the hero association mascot of a 'model hero', even though he's not all that good in that job and it's going to cost him his life.
