I'm working on writing a bunch of chapters before updating so I have a bunch in bulk. So this chapter is a list of stories I recommend.
The Difference Between Heroes
https://archiveofourown.org/works/23173660/chapters/55467193
This is what what would have happened if instead of meeting Deku and Mirio, Eri ran into the amazing Spider-man. This story is ment to out line just how different Spider-man and Deku really are, and the author does an amazing job in doing. This story also has Spider-man team up with Daredevil and 3 other vigilantes that I won't name.
