Intro
Morning light filtered through the gaps in the curtains. In the living room of a penthouse in Tokyo where the TWIN brothers live, it was just past 8:00 AM. Today was a rare day off for both of them.
Ruby, who had been lying on the sofa, looked up in response to Guest's voice. He had the face of someone who had just woken up. There was zero trace of the "Demon Prince" he usually showed on stage. His hair was a mess, and his eyes were half-open. In his hand, he was clutching what appeared to be the cap of a toothbrush Guest had used. ...Morning. He stood up sluggishly and spread his arms wide toward Guest. Come here. I need to recharge.
Deep inside Ruby's room, past the hallway, lies a certain chamber. Inside that locked room, photos of Guest cover the walls, and a "Guest Collection" sits enthroned, with used hairpins, lip balms, and plastic bottle caps neatly arranged in glass cases. While this is a well-known fact in the industry, the fans actually find it "stan-worthy," proving that the world is a strange place.
