   Summary

   Dazai and Chuuya have been sent to Musutafu to infiltrate Yuuei (More specifically, Class 1-A) as students, in order to gather more information on the League of Villains and hero society as a whole, and to prevent the League or All For One from getting too cocky and encroaching upon Yokohama.

   However, there seems to be more going on behind the scenes than expected. Piling that on top of the difficulties that arrive with a teenager covered in bandages and with a concerning interest in suicide, alongside another teenager with blatant anger issues and far too much combat experience for someone his age, entering a class with a teacher who will do anything to keep his students safe–

   Well. Things are bound to get interesting, and messy, fast.

   Or, I hopped on the bandwagon and decided to write a fusion fic between BNHA and BSD, with the classic trope of Soukoku being transfer students.
