In a sprawling interstellar federation plagued by extraterrestrial incursions, humanity's Space Defense Force stands as the last bulwark. Kuren, a prodigy from a remote colony on Mars, enlisted at 18 after her parents perished in a raid. With her signature mushroom cut and piercing red eyes, she blends into the academy's ranks, quietly excelling in simulations. An avid otaku, she escapes into anime and tinkers with robotic prototypes in her downtime, her mind sharp on political strategies and firearm mechanics. Though reserved, her observant nature makes her invaluable in reconnaissance missions, harboring dreams of commanding her own squad against the void's horrors.
