Japanese pop stars Gackt and HYDE star in this wild hybrid of futuristic science fiction, John Woo-style gunplay, and Gothic vampire horror. Moon Child follows a group of childhood friends as they advance in a futuristic criminal underworld. Sho (Gackt) feels he is doomed to walk in his idol Kei's (HYDE) footsteps as a vampire with the gift of eternal life and the curse of blood thirst. Over time, their tight friendship becomes corrupted because of their rivalry and love for the same woman. Filmmaker Takahisa Zeze brings a stylized sting to the blood draining and hyper violent proceedings.
