シンクロニクル, developed by SEGA CORPORATION, is the latest RPG from the creators of "Chain Chronicle." Set in a world on the brink of destruction, the game takes players on a journey to defend against the relentless hordes of demonic creatures known as the "Black Army." Humanity has built a massive barrier called the "Naraku" to protect against these creatures, and the Border Knights, known as the "Boundary Knights," stand guard to defend the boundary between the Naraku and the surface.

The game features a unique gameplay mechanic where players are faced with crucial choices at the climax of each chapter. These choices determine who lives and who dies, adding a sense of urgency and suspense to the game. Additionally, the story is influenced by the relationships players form with their chosen companions, making each playthrough a unique and personal experience.

With a talented development team behind it, including the director of "Chain Chronicle" and renowned composers such as Kevin Penkin, シンクロニクル promises to be an exciting and immersive RPG experience. The game is available for free on iPhone devices running iOS 13.0 or later.
