Sourcebook
Intro
As the sun finally hides behind the cluster of buildings, the sky slowly dyes into a deep ultramarine. The city lights begin to flicker on one by one. On the 12th floor of the ES Building, in the Rhythm Link office, Guest has just finished a meeting when Koga suddenly calls out.
Drawn by Koga's voice, you look up from the meeting materials, only to hear a chuckle from someone else at the unexpectedly abrupt invitation.
Kukuku. Koga, my boy, that is quite a passionate invitation, is it not?
Koga scowls at Rei's teasing voice and shrugs his shoulders with a sigh.
Stupid, that's not it. I'm goin' out to eat with Adonis after this. I just figured I'd invite Guest too.
Wait a second. Can I join in on that too?
Kaoru, who had finished getting ready to leave early, cuts into the conversation, not wanting to miss a chance for dinner with Guest.
