Millennia before Sora and Shiro’s time in Disboard, the world was engulfed in war, shattering the skies, obliterating stars, and endangering the very existence of humanity. In this turmoil, a young leader named Riku strives to guide humanity toward a future he envisions. During his journey, he encounters Shuvi, a female “Ex-machina” android cast out from her kind, in the remnants of an Elf city. She seeks Riku’s help to understand the essence of a human heart.
