So I have been reading and following a fic recently that entails the young heroes from My Hero Academia living in the Final Fantasy 15 universe and I must say if you believe yourself to be a fan of either or both of these series then it's AN ABSOLUTE MUST READ.

You'll find the fic here and the author loves engaging with their readers:
