|Silent Möbius (サイレントメビウス Sairento Mebiusu) is a twelve-volume manga, a 26-episode anime series, and a pair of motion pictures, created by manga artist Kia Asamiya. Both anime versions have been licensed by Bandai Entertainment. It is heavily influenced by the film Blade Runner and is centered on the lives of the Attacked Mystification Police Force (AMP), a dedicated group of all-female police officers with varying talents and personalities protecting Tokyo from an invasion of extra-dimensional creatures called Lucifer Hawks. It is published in English by Udon Entertainment; previously it was published in English by Viz Media.
In 1999, Gigelf Liqueur, aided by the Magician's Guild, set into motion a plan to open a gate between Earth and the world of Nemesis. The intent was to exchange Earth's polluted air and water with clean air and water from Nemesis. To aid in this endeavor, a huge cyclotron was built under Tokyo. Unfortunately for all involved, Ganossa Maximilian—Gigelf's old apprentice—sabotaged the plan, opening the gate early and perverting the gate for his own means. Following this event, Gigelf and the Magician's Guild battled an invasion of Lucifer Hawk (the name for the inhabitants of Nemesis) for a number of years. Gigelf was killed in 2006 and it would seem that the rest of the Guild met similar fates over the next few years.
In 2023, Rally Cheyenne, daughter of Guild member Lufa Cheyenne and born mixed heritage (her father was from Nemesis), felt partially responsible for the growing attacks on innocent humans by marauding creatures from Nemesis. She started the organization with a mere three officers (Kiddy Phenil, Lebia Maverick and Nami Yamigumo) and a sub-commander (Mana Isozaki). Over the next few years, she added Yuki Saiko, Katsumi Liqueur and Lum Cheng to the team, aiding in the fight to protect Earth from the vicious Lucifer Hawk.
