Stella Sora is a top-down light-action RPG developed and published by Yostar, the studio behind Arknights and Azur Lane. Set in the world of Nova, players take on the role of a Tyrant who commands a team of heroines called Trekkers to ascend the floors of massive, mysterious structures known as Monoliths in search of ancient Artifacts.\n\nCombat blends real-time action with roguelike and reverse bullet-hell mechanics. Players control one Trekker directly while two others provide support, and between floors they collect randomized buffs, items, and equipment called Disks that shape each run. The gameplay loop emphasizes strategic team composition and build variety across ascending dungeon floors.\n\nStar Sora also features relationship-building elements, allowing players to deepen bonds with Trekker characters through story choices. New Trekkers and Disks are obtained through a gacha banner system with a guaranteed pull at 120 for limited characters.\n\nThe game launched globally on October 19, 2025, across iOS, Android, and PC (Windows).
