Yuu's beating himself up too much. He did a surprising amount of good for someone without powers and gadgets that he can't even use properly thanks to his non-superhuman physical ability. It'll be interesting to see if he'll be of any significance to the story afterwards, not being an actual Spider-Man himself.
And oh boy, here we go. Fingers crossed that the sales quota can be reached. I think we all seriously want to see where this story goes.
