Canaan is a 13-episode anime television series, conceptualized by Type-Moon co-founders Kinoko Nasu and Takashi Takeuchi, based on the scenario that they created for the Wii visual novel 428: Shibuya Scramble, which is noted for being one of the few games to have been awarded a perfect score by games publication Famitsu. The series spawned manga and light novel adaptations.

Taking place two years after the events of 428: Shibuya Scramble, Canaan centers on three women, their connections to one another, and an upcoming anti-terrorism summit in Shanghai, China. The first woman is Canaan, a Middle Eastern assassin and mercenary. The second is Alphard Al Sheya, Canaan's rival and a skilled assassin who heads the terrorist organization known as 'Snake'. The final girl is Maria Ōsawa, a returning character from the Shibuya incident, who came to Shanghai with her fellow reporter, Minoru Minorikawa. Their subsequent encounters lead to armed interventions between Canaan and Alphard, along with the reveal of their deep and tragic past.
