Nayuta no Kiseki: Kai

Nayuta no Kiseki—an ambitious entry in the Trails series originally released for PSP in 2012 that adopts action RPG-style gameplay—returns for PlayStation 4 as the latest entry in the Kai series (enhanced ports of older Falcom games). In addition to new illustrations for the main characters, new illustrations have also been added for each of the characters that appear on “Remnant Island,” where the game’s story is set. Graphical elements have also been significantly enhanced, including dedicated illustrations for event scenes and other visual aspects. There are also various other upgrades that take advantage of PlayStation 4, including 60 frames per second support, high-definition image quality, and high-quality background music and sound effects, making the story of Nayuta no Kiseki more accessible than ever before."

The Legend of Nayuta: Boundless Trails is set in two worlds: the main characters' home world, and a mysterious world called Lost Heaven. The main characters' hometown is Remnant Island, located in the center of Ciencia Sea, a vast ocean with countless islands. Shooting stars have been continually falling from the sky for some time, leaving much of these piled up on the island. Stones known as "Star Fragments" have been discovered in these areas. By shining a light on them in a certain way, people can see the phantom world of Lost Heaven. The story follows Nayuta Herschel, a young aspiring researcher aiming to see what's further beyond the known world, who was just returning to Remnant Island for the summer, when he and his childhood friend Cygna Alhazen find themselves in the world of Lost Heaven through the guidance of the otherworldly fairy Noi, as they get involved in a plot to stop a madman and his right-hand man from destroying Lost Heaven and potentially Nayuta's own world in the process.
