There is this slowly-growing gacha game genre that is quite distinct. "Post-apocalyptic or pseudo-post-apocalyptic world with lite-sci-fi technology, where an elite organization of cool anime operators fights against monsters, mutants, and robots." Wielding guns, high-tech melee weapons, magic, and/or "magic," they blast their way through a colorful assortment of global-scale threats.
Think Girls Frontline, Honkai, Arknights, Punishing: Gray Raven (the edgiest take on the genre), Blue Archive (the lightest and happiest take on the genre), etc.
Post shit that fits that genre definition and art that looks similar or fits the aesthetic.
