Magical Girl Spec-Ops Asuka - S01

Three years ago, a bloodthirsty race of interdimensional beings called the Disas appeared and destroyed everything they could reach on Earth. With ordinary weapons useless, humanity's only hope of survival rested on humans who became magical girls after forming an alliance with the Spirit Realm, which had followed the Disas to Earth. After a violent conflict, the squad of magical girls came out victorious, and the survivors became known as the "Magical Five." After the war with the Disas, the Magical Five disbanded. Kurumi Mugen, Mia Cyrus, Tamara Volkova, and Lau Peipei each continued their own military service independently, while their leader, Asuka Ootorii, retired and became a high school student. But Asuka's peace does not last long, since it seems there were survivors on the enemy's side as well. Because magic must be fought with magic, Asuka is pulled back into combat as an even worse battle looms ahead.
