Dead End Aegis

Dead End Aegis (魔法少女消耗戦線 DeadΩAegis, Mahou Shoujo Shoumou Sensen - DeadΩAegis), sometimes stylized as DeadΩAegis, is a Science Fiction Visual Novel developed by metalogiq and released in March 2021. It was translated by JAST, who released it in January 2022.

It's the year 2099. Mankind is broadening their horizons in the outer Solar System when they make contact with the Cosmic Cnidarians, or C.C. The ensuing Alien Invasion leads to many casualties and forces the evacuation of the bases in Mars and the Moon. At that moment, the first Magical Girls show up, with Lisette Augerau leading the charge and putting a stop to the C.C. invasion for good. Along the way, she saves the last survivor of Mars, a girl named Minori Iizuka.

Nine years later, the United Earth Forces are still raging the war against the C.C. Their stronghold is the Cathedral, a Space Station located in the space sector where the aliens live. From there, they dispatch these magical girls formally known as Special Warfare Troopers. Minori feels indebted to Lisette and her heroism, so she trains in the officers' academy to join the Special Warfare Troopers, leaving her crush Mitsuomi behind. Little does she know how harsh life in the Cathedral will be...

A short prequel titled DeadΩAegis: Gaiden tells more details about the first C.C. invasion from the point of view of Lisette and her friend Circe.
