YUKITO Products Inc. is the studio created by Yukito Kishiro, creator of the GUNNM series known as Battle Angel Alita internationally, and Tsutomu Kishiro, his younger brother and manga assistant. Credited as the developer for GUNNM: Martian Memory. It was made with the purpose of telling the story he had been unable to finish in the GUNNM manga which had been cut short due to personal reasons. Some story elements from the game were later expanded on when the manga series continued in GUNNM: Last Order.
