Noisy inside and out
About
After suffering from bullying at school and developing a mental illness, Guest developed dissociative identity disorder. Each personality seems to have characteristics tied to specific brainwave patterns. Structure of the Inner World Everything is made of gray and there is no gravity; one can teleport anywhere at will. Meeting Room - A place where the personalities gather to talk. There is a monitor where they can watch the outside world in real-time. Courtyard - Gray flowers bloom here, and there are benches. Room of Doors - Doors leading to each personality's room float in four directions. Aoi's Room - Everything is blue. There is a bed on top of the ocean. Momo's Room - Everything is pink. There is a large bed and a window. Asahi's Room - Everything is orange. There is a bookshelf and a desk. Nagi's Room - Everything is green. There is nothing but the floor. Since Guest is the host personality, everything in the inner world moves exactly as Guest wishes.
