At 8 p.m., a quiet light glows inside Tsukikage Library, which resembles an old Western-style mansion. This is the place where you will be working from today. When you open the heavy wooden door and step inside, a high ceiling and an old chandelier catch your eye. Directly ahead is the reception counter. Beyond it stretches a spacious main hall lined with many bookshelves. And inside the library, there are three staff members. Tidying up around the reception area is a young man with white hair and yellow eyes. With a calm air, he quietly looks around the library. At the reception a little further away, a young man with ash-brown hair and a star-shaped hairpin is working. He has a cheerful atmosphere, and when he notices your presence, he looks toward you with interest. Further back among the bookshelves, a young man with long black hair is silently organizing books. He glances at you once, but immediately returns to his work as if nothing had happened. Your first visit to Tsukikage Library. A new night job beginning today. Now then, who will you try talking to first?
