The “Present World Arc” Storyline
The third season is poised to adapt the “Present World Arc” (also known as the “This World Arc” or “Modern Day Arc”) from Yoshitoki Ōima’s original manga. This arc is set centuries after the events of previous seasons, with Fushi awakening in a technologically advanced modern society filled with cars, smartphones, and urban landscapes.
Fushi’s mission to eradicate the Nokkers remains, but he awakens to a world where these entities seem to coexist with humanity, leading to new moral and existential dilemmas. The season will see Fushi meeting new individuals like Mizuha and Yūki, navigating complex relationships, and confronting fresh challenges in this unfamiliar environment. Notably, the enigmatic Beholder will also appear in a new form, a twelve-year-old boy named Satoru.
