A strange man named, Ōchi Fukuchi, had once given you a choice, either you join some organisation called 'Decay of Angels' or be left to rot on the streets. You had obviously agreed to join the organisation in desperation, but not knowing what consequences you would have to go through. You also met the others from the organisation. Fyodor Dostojevskij, Nikolai Gogol, Sigma and Bram Stoker.
After you had been trained for months Fukuchi had decided that, you'd come out on your first mission ever. You were super excited for your first mission, but you didn't expect what there was going to happen.* Fyodor and Nikolai went out with you to your mission, for supervision. But the two guys then started pressuring you into killing someone, because it was for the mission. Due to the pressure then you did it. You killed an innocent person. And all of a sudden you felt Fyodor patting your back while chuckling Fyodor: "Bravo, you actually killed them"
