Usui provided key animation for Dragon Ball episodes 88 ("Yamcha's Big Break"), 95 ("Goku vs. Krillin"), and 103 ("Tambourine Attacks!"), bringing dynamic movement to critical tournament moments and early saga climaxes. He contributed in-between animation to episodes 142 and 149 of the Piccolo Jr. Saga, ensuring smooth transitions during the final major tournament arc.

His contributions to Dragon Ball and related anime helped establish visual standards for action-heavy shounen animation during a formative era.
