In a distant future, humanity had achieved space travel and thrived. However, an unforeseen event called the Jikushin, a temporal and spatial earthquake, caused all networks to fail and civilizations to reset. Despite this setback, humanity managed to rebuild and prosper once again. The Transvaal imperial country emerged as the center of the galactic system during what came to be known as The Second Age of prosperity. The lost technology from the previous civilization, deemed godly, became the focus of the Tsuki no miko priests' worship. Meanwhile, a guard fleet stationed in the galactic system's frontier existed, with one peculiar group named Angel Corps, composed entirely of women. They operated the Angel Frame, a relic of lost technology, and were tasked with collecting and managing this technology. The Angel Corps were not elite pilots, but a group of eccentrics, comprising Forte the arms maniac, Mint the costume player, Vanilla the taciturn, showy Ranpha, and Milfeulle, who loved to cook. However, their missions were never smooth, and they always managed to stir up trouble.
