Yostar's Stella Sora Fantasy RPG Launches Globally

Yostar launched Stella Sora globally on October 19, 2025 (UTC-7), bringing a top-down action RPG with roguelike mechanics to iOS, Android, and PC. The free-to-play title marks Yostar's first major in-house developed game, shifting the company from its role as publisher of titles like Azur Lane, Arknights, and Blue Archive to creating original content.

Players awaken as the legendary "Tyrant" after millennia of slumber, journeying across the Nova continent alongside distinctive "Trekker" companions. Combat blends real-time action with bullet-hell elements, where players control one primary Trekker supported by two others, emphasizing dodging, skill timing, and chaining attacks through procedurally generated Monolith dungeons.

About the Game

Stella Sora is an action RPG that blends roguelike progression with bullet-hell combat. Set in a vibrant fantasy world, the game features vibrant, moe-style visuals and a lighthearted road-trip anime aesthetic.

Players awaken from a long slumber as the "Tyrant," discover mysterious Monoliths scattered throughout the land, and form bonds with unique Trekkers while uncovering the secrets of this colorful realm. Multiple storylines branch throughout the adventure, allowing players to shape their journey through the Nova continent.
