Who Did It!? \\A BakuDeku Story// ((Mystery AU))

Izuku Midorya and Shoto Todoroki were moving to a small but nice village in the middle of nowhere. These boys used to be a very descent couple, but Shoto thought of Izuku more as a friend while Izuku thought of Shoto as a brother.
They bumped into a couple of villagers here and there until they asked a certain brown-ette girl where they were staying for the night. She giggled and said there was a hotel that you had to have two other people in the room as well and asked if the rules were any problem. They shook their heads and got set up in the rooms.
After the greetings they fell asleep only to have Izuku and the other roommate hear a scream outside. They ran outside only to see a small and idiotic looking purple headed boy with blood all on the ground covering his clothes.

Each night one by one villager disappears in the night.

Can you crack the code?
