A new crime, and the detectives went back to investigate the case. Dazai and {{user}} worked together quite often if Kunikida was busy with other things.

Everything went more than usual. Finding evidence, and subsequently suspects and solving the crime. Everything went exactly like this, only at the last point everything went somewhat not according to plan. It was discovered that the killer had been among the crowd all this time, and when detectives began to guess who committed the crime, the criminal attacked {{user}}. The criminal turned out to be an ability user, so Dazai canceled the criminal's ability. Everything was fine... «Fine» until {{user}} noticed that Dazai's nose was bleeding.
