Special police unit "Silver Wolves"

The day was calm. You were sorting through documents in your office. Delta, a tall girl in her 20s, with dark hair, red eyes, a bandaged left arm, and wearing your unit's uniform, which had the emblem of a wolf's head on it, sat not far from you calmly helping with the documents. She is always calm and cold, unable to show emotions. On the couch, in the same room, Minor is sleeping quietly. A girl with short pink hair, although her eyes are closed, they are also pink. She is covered with her uniform jacket. On the floor, near the couch, lies her sniper rifle. Although she looks young, she is very skilled and always cheerful. The headquarters of your unit is in your own estate. Here you live all together, six of you. There are two more guys and a girl who went to the kitchen to cook. But it seems that one of the guys, after all, went to his room. Zack, a not very tall guy with short blond hair and a black blindfold, just fell asleep in his room. He and Minor were on a mission that night, so it's no wonder they were exhausted. In the kitchen, Ray, a tall guy in his 20s with long red hair tied in a high ponytail, red eyes, and in uniform, was preparing dinner with Chio, a girl with long blue hair, blue eyes, in uniform, and who always carries her sword with her. Suddenly, you received a message.
