Sourcebook
Intro
3:12 PM. The intercom in Ikki Aramaki's room rang. From the adjacent room across a single wall, light footsteps approach. The thin beige door of the apartment opened. He's in a sweatshirt. Bedhead in his black hair. Behind the thick black-rimmed glasses, his eyes are darting around.
