The outpour of grief from his co-workers indicates that he was well-liked among the staff, something deeply necessary in anime's punishing development schedule.

He will be missed.

As a director, Nagamine offered action that was dynamic without being cluttered, exceptionally crisp without feeling out of step with the rest of the series. Hi episodes had an impeccable sense of timing, one that series like OP, which could fall prey to lackluster pacing, sorely needed.

His work as series director on the Wano arc, one that saw the One Piece anime aesthetic revised and supercharged, has been a major pillar of its current international success. I hadn't seen people so excited to watch it on a week-to-week basis in my entire time as a fan.

Meanwhile, Film Z remains one of the most poignant and exciting stories to come out of the entirety of One Piece. A sad tale about coming to grips with the past and making way for the future.

He was a longtime Toei staple (Did some fine work on the PreCure series!) but his one-two punch of direction on Dragon Ball Super: Broly and One Piece Film: Z is a stellar record on its own. Broly helped make Dragon Ball films feel like events again...
