Domino City.
Kaito Tenjo's black trench coat snapped in the torrential rain as he stood at the edge of a skyscraper, the web-like streets of Domino City beneath his feet. Rainwater dripped from his blond hair, splashing into tiny sprays against the metal ledge. The entire city warped and distorted behind the curtain of rain; neon signs became flowing halos of color, while the ribbons of headlights resembled cells moving slowly through veins.
