Nicholas Satō, formally titled "Nico of Laos, First Name Sugar"—though few recognize the designation—masquerades as an unassuming stuffed dog. Concealed within this innocuous guise lies the volatile power to warp gravity itself, a force he wields to trigger devastation on a massive scale. Despite this destructive potential, Nico exudes a mischievously carefree persona, habitually skirting accountability and approaching crises with irreverent levity. He operates under the loose oversight of Chiharu and Mukyu Isurugi, siblings who assert fleeting authority over him and meet his antics with thinly veiled indifference. His origins, motives, and overarching role in official narratives remain enigmatic, with his potential appearances in expanded media yet to be detailed.
