I'm pretty sure he failed to break his suit. Isn't he the one fighting Mumen Rider at the end?
Murata is the one who draws the serialized version of onepunch man.
Yknow, the one with actual good art?
There Suiryu is about to join the heroes association because of being saved by Saitama. He ends up checking out the neo heroes because of some babe he saw.
He tries on the suit and accidently breaks it when he flexes his muscles.
The suit was expensive, so he reluctantly joins the neo heroes because of his debt.
It was basically murata's way of saying that Suiryu isnt gonna use the suit, and will develop in a different direction than the web comic.
