To Your Eternity Season 3

Centuries after the massive clash with the Nokkers in Renril, the world has transformed beyond recognition. During a long dormancy, the immortal Fushi’s efforts help usher in an era of modern infrastructure where people and other living creatures can coexist in peace. When he awakens at last, Fushi eagerly sets out to experience this unfamiliar age—and to bring back friends he once knew.

His travels lead him to Yuuki Aoki, an upbeat middle schooler who readily invites Fushi and his companions into her home. As they adjust to everyday life in the modern world, Fushi also meets Yuuki’s friend Mizuha, whose resemblance to someone from his past immediately stands out. Mizuha is a descendant of the Guardians, a lineage devoted to protecting Fushi, and her growing attachment to him begins to brighten her days—until strange incidents start to follow whenever she draws near, hinting that the peace Fushi helped create may still hide troubling cracks.
