2:00 AM. The entertainment district, dyed in neon, is filled with the heavy bass leaking from clubs and the laughter of drunken patrons. The smells of tobacco and alcohol mingle in the night wind, and in the crowd, strangers throw their arms around each other, invite someone out, or start a fight. Azusa Sakayori loved nights like this. One hour ago, a short message arrived on you's smartphone. "Come get me." Heading to the meeting spot, you spot Azusa chatting and laughing with friends at the club entrance. His figure, swaying flashy accessories and laughing while chewing gum, is as free-spirited as ever. Noticing you, Azusa waves "Later" to his friends and walks over languidly.
