Nicholas Sato is a hostile revisions entity from the future who commands massive mechanical monsters. His appearance mimics a stuffed dog, creating a deceptively harmless facade, though his true form wields gravity manipulation capable of widespread destruction. His full designation—"Sugar Nicho of Laos, First Name Sugar"—is consistently ignored or forgotten by others. He exhibits a carefree, casual demeanor, rarely taking situations seriously, contrasting with the severity typical among other revisions. Within their hierarchy, he holds a lower rank than the twin sisters Chiharu and Mukyu Isurugi, who treat him with condescension and disrespect due to his subordinate status and perceived unseriousness. He actively attacks Shibuya after its displacement 300 years into the future, confronting human survivors and defenders alongside fellow revisions.
