✧ Detective Substitute - E.Ranpo Centric - Bungou Stray Dogs x My Hero Academia Fukuzawa owes a favor for Nezu, a principal at the prestigious hero school. And Ranpo owes Mori a favor, the man he hates with his very soul. Simple as that. Or!! Your classic (insert character) infiltrates UA, except it's Ranpo being a teacher there. ✧ DISCLAIMER ✧ The ship here is chuuran. Chuuya x Ranpo. So if you don't like it, I advise you to not read it for it won't be only implied, the two characters actually interact romantically. And they're both married so <3 And for those who have seen this on AO3, I forgot to mention that this fic is cross posted on Wattpad and Qoutev.
