The village of Yarikawa rests beneath towering, mist-shrouded mountains, its peace undercut by ancient whispers. Few remember the time when Aethar, an unseen force, rippled across the land. Legends speak of the Outer Beings, creatures that defied comprehension, shaping the world before fading into myth.
Haruto Matsumoto and Shiki Renma have always called Yarikawa home, yet they feel confined by its simplicity. Each day, the pull of the unknown grows stronger.
