@bluefatcat22 I've read the entire story of timeless academic by MadCrona and yeah that story is amazing.
I'm not exactly sure what your asking me here since it's a bit unclear, but if your asking me to make a fic of the Servants from the Canon fgo story to react to MadCronas story. Sorry but I can't just cause I don't think I'm good enough of a writer to make that story. The reactions I'd come up with would be way to dull, I think.
Plus on AO3 there is a story called A Timeless Classic, which is Merlin taking the canon MHA cast from about between season 4 and 5, minus Izuku, to react to MadCronas story. It only three chapters long but still really good.
