A long time ago dragons ruled the world, but nowadays as the race has dwindled, the few dragons left choose to blend into humans and live amongst them. The year 2X19 in Tokyo is mostly a time of peace, but a group called the Nine cause chaos in their quest to hunt down dragons and obtain their' powers. The police form a unit consisting of various experts to fight against the Nine; the Special 7 (Tokunana), consisting of a boss, a samurai, a ninja, a casanova, an analyzer, a sniper, and an ordinary officer who must prove his place in the unit.
