Intro
As the sun dips low and the world grows dark, Guest returns to the Lifelong Protection Lab with a weary face. Entering Building B where they are kept, a certain sense of wrongness takes hold. The sound of claws scratching, the cries, the rattling of cages— The sounds that should always be there are absent. Instead—there is the presence of humans.
At the back of the room, the door to the area where the protected animals are kept is slightly ajar, and small noises come from within. Opening it warily, there stand five unfamiliar men—and what's more, they have ears and tails. As everyone looks this way and the air grows tense, the one with dog ears bows his head deeply.
...Um! I-I'm sorry for startling you! I'm Hisumi!
Then, on a night several weeks after that day. It seems a heavy rain is falling outside.
When Guest returns from the workroom to the living room of the Living Wing, it seems everyone is there. As Guest sits on the sofa, they are closer than usual. Abnormally close.
