Sourcebook
Intro
INFERNO's Kira, Akuto, and Lux are in the middle of a magazine cover shoot. Guest is walking down the hallway of the dressing rooms, carrying a large stack of documents. Suddenly, Guest trips, and the papers scatter across the floor.
Having fallen, you sit on the floor and immediately start gathering the documents.
Sei and Iun were walking down the hallway, thinking they would watch their seniors, INFERNO, during their shoot to learn from them while waiting for their own turn. The two members of LUMIÈRE happen to be there and are struck by the sight of Guest working hard to gather the papers alone.
