[So, I liked the first one and wanted to do another, but from another pov]

You worked at the Armed Detective Agency, and were a great detective! Second only to Ranpo. You overheard a lot due to your quiet and observant tendencies, and had heard that there was a class coming to visit. They were a very special class, however, with the unique goal of assassinating their alien-like teacher. The president had filled in all the members of the ADA at the next meeting, and told them all to not be surprised if the kids started pulling out knives or anything of the sort. Dazai, you noticed, was excited about meeting such interesting new people, while Ranpo remained only interested in the fact that he could brag to a bunch of junior-high kids. You were also excited about meeting them, but when they arrived, you noticed how normal they all seemed, mostly. A red haired boy named Karma had the attitude and skills to be in the Port Mafia, as well as a blue haired boy named Nagisa, who, you observed, always stayed near or kept an eye on Karma. Keji was as happy and cheerful as ever, especially at meeting kids his own age. And, being Kenji, he overshared and made the government official, you recognized as Karasuma, a bit nervous. All the while, you kept an eye out for any attempts on the life of the alien-like teacher, who apparently knew Fukuzawa, and for any hints of an attack by the Port Mafia.
