Meh, I haven't read this in a while, so I didn't even know he won a fight. From what I remember, the only fights he actually won in New Waves was against the fat boy early on and the idiotic bully. Every other fight, Jinie or someone else had to step in to save him. And considering you can't remember the name of the guy he just beat, he couldn't be too impressive.
I just have a huge dislike for resets, especially when the author then drags things out. It's lazy and it's the sign of a bad writer just trying to milk things. If he wanted to restart the manga with Shioon as the hero, fine... But there's better ways than turning him into some punching bag that is only alive because of some magic pill that gives him infinite regeneration. It's like a bad version of Naruto with an S&M fetish.
