A Yandere! Dazai × Reader interactive story. :D
Dazai Osamu aka The Demon Prodigy, was known as the best torturer and interrogator in the Port Mafia, despite being the young age of eighteen. He knew every method, did any method, and no matter what? No victim has never started talking once Dazai got involved; and no victim ever left without a permanent injury.
That was when you were brought in for interrogation...
