 Taki is assigned to go after Daishu, a businessman who is suspected by the police to be selling the drug "happiness", a drug from the Rapter s world that causes people to "evaporate" if they stop taking it. Actually it is another group of Rapters that are selling the happiness. The second group attacks Daishu s group, and eventually Taki, Daishu, and Daishu s daughter join forces to fight the evil Rapters. Lots of psychic powers, shape changing and general weirdness.
