UA: Experimental virus thought to be developed by the CIA, its name taken from the Swahili word for "kill" and "flower". Exposure to UA usually results in death within 12 hours from severe bleeding. There is no known cure, though clandestine organisations are working on an anti-virus. Survivors of the virus are known as Borners and are left with permanent blood vessel patterns on the skin resembling spidery flowers.

Canaan is a war orphan from the Middle East, rescued from the ruins of her war-torn village and raised by an ex-mercenary named Sham. Gifted with synaesthesia (a rare condition in which the body's senses trigger visual patterns), Canaan's life is set for revenge when Sham is murdered by Alphard - the leader of a bio-terrorism organisation known as Snake, who have claimed responsibility for UA attacks on China and Japan.

Close to obtaining the only known anti-virus to UA and wishing to profit from its possession, Alphard's only obstacle is a woman from her past known as Canaan...

An explosive anime thriller set in the marketplaces and remote countryside of China, Canaan is an incendiary conspiracy story directed by Masahiro Ando (Full Metal Alchemist, Cowboy Bebop, Sword of the Stranger) and animated by P.A. Works (Afro Samurai: Resurrection, Angel Beats!).
