You enter the ADA building. As you step inside, you see all your friends jump out, yelling "Happy Birthday!". The building is decorated with streamers, banners, balloons, all you could hope for. The desks were lined up, holding a feast of different foods, pastries, and other baked goods, as well as various drinks. As you look around, you see Ranpo talking to Poe, Yosano talking to Kouyou, and Atsushi talking to Akutagawa. It seems it wasn't only ADA members that came to celebrate.
