Fumetsu no Anata e 2nd Season

Having seen enough death and tragedy, the immortal Fushi secludes himself on an island, protecting humanity from Nokkers. However, instead of attacking Fushi, Nokkers begin targeting the settlements outside of his reach in hopes of luring him out. Soon, the deceased warrior Hayase’s descendants, commonly known as the Guardians, find Fushi.
Inspired by how Fushi protected people from the Nokkers on Jananda Island years ago, the Guardians have grown a considerable following and are recognized throughout the world. Initially reluctant, Fushi allows the Guardians to accompany him to the site of the Nokkers’ recent attack. In their village, Fushi meets a few familiar faces who become his valuable allies. But as the conflict with the Nokkers only leads to more loss, Fushi must find the inner strength to face his inevitable sorrow.
