Stella Sora, the latest RPG from Yostar for PC and mobile devices, is now available worldwide. The PC version’s launcher is available on the official site, while the Android and iOS ones are on the Google Play and the App Store. Chitose appears as the first five-star Trekker on the banner, and the first five-star Runic Disc is Sword Against Stream. There’s also a launch PV highlighting some of the game’s characters.
We already knew a bit about how Stellar Sora works, as Yostar held a closed beta in June 2025. You explore areas with Trekkers in the action-RPG, taking down enemies. As you do, your Squad Level goes up. This means picking one of three level-up bonuses for that unit’s abilities. An early gameplay trailer showed Noya in battle, with Amber and Iris’ abilities equipped. As for the dating sim elements in Stella Sora, you get to build up bonds with characters as you make decisions while playing, which affect your relationship.
There are a number of launch bonus rewards for folks to claim as they get started. A seven-day login event involves a Rainbow Disc Pack, a Stellar Resume Pack, and 10 Cerulean Tickets for the gacha. Everyone also gets 10 Sprout Tickets and 3,000 Silver Discs in their inbox right away. Among the other initial launch event rewards are a Permanent Banner five-star Trekker character.
Finally, here’s the launch video showing the Trekkers Amber, Noya, and Iris from New Star Guild trying to find a lost cat.
Stella Sora is available for Windows PCs and mobile devices. The Chitose Trekker and Sword Against Stream Runic Disc banners will run until November 10, 2025.
