Blue Lock Role

Yuki Ono voices Seishiro Nagi in the original Japanese version of Blue Lock, a technically gifted but famously unmotivated striker whose natural talent rivals protagonist Isagi's own. Nagi's arc traces his reluctant awakening to real competitive drive after being paired with strike partner Reo Mikage inside the Blue Lock program. The role leans on the deadpan, understated delivery Ono is known for, a contrast to the series' typically high-energy sports-anime cast.
