Steel Ball Run Cast, Characters, And Seiyuu Guide

JoJo’s Bizarre Adventure: Steel Ball Run isn’t just a new arc; it’s a fresh rebooted universe with a completely new lead cast. David Production and Netflix treated that transition seriously, assembling a powerhouse lineup of Japanese seiyuu and English dub actors who already carry massive roles from Chainsaw Man, My Hero Academia, and Jujutsu Kaisen.

Whether you watch subbed or dubbed, here is your definitive guide to the voices bringing Hirohiko Araki’s 1890s cross-country horse race to life.

Main Steel Ball Run Cast (Japanese and English)

Here is the complete launch roster for the main competitors and key figures in the Steel Ball Run race.

Johnny Joestar – Shogo Sakata / Daman Mills

Shogo Sakata is a relatively young seiyuu, but you have almost certainly heard him if you watched Chainsaw Man—he provided the iconic voice for Aki Hayakawa. He has also played roles like Ken Usato in The Wrong Way to Use Healing Magic. On the English side, Daman Mills voices the paraplegic former jockey, bringing experience from a massive list of shonen dubs to give Part 7 a grounded, intense English lead.

Gyro Zeppeli – Yohei Azakami / Kaiji Tang

Yohei Azakami steps in as Gyro Zeppeli, the steel‑ball‑throwing mentor with more secrets than he lets on. He is less of a ubiquitous “headline seiyuu” than some of his co-stars, but that is classic JoJo casting—Araki’s biggest oddballs often go to actors who can build a theatrical character entirely from scratch. In English, industry veteran Kaiji Tang plays Gyro, bringing the exact same charismatic weight he showcased as Ichiban Kasuga in Yakuza: Like a Dragon and Satoru Gojo in Jujutsu Kaisen.

Diego Brando – Kaito Ishikawa / Damien Haas

Kaito Ishikawa voices Diego Brando, giving the “not Dio, but absolutely channeling that energy” rival a brilliant edge. You likely know Ishikawa from roles like Tenya Iida in My Hero Academia. Popular voice actor and Smosh personality Damien Haas voices Diego in the English dub, perfectly rounding out the new timeline’s main rival trio alongside Johnny and Gyro.

Lucy and Steven Steel – Rie Takahashi / Frankie Kevich

Rie Takahashi plays Lucy Steel, bringing top-tier industry experience from massive leads like Emilia in Re:Zero and Megumin in Konosuba to one of Part 7’s most critically important narrative characters. Frankie Kevich handles Lucy in English. Meanwhile, Kenta Miyake (famous for voicing All Might in My Hero Academia) voices the eccentric race promoter Steven Steel in Japanese, with the legendary Jamieson Price taking on Steven in the English dub.

Sandman and Pocoloco – Masaaki Mizunaka / Kenichiro Matsuda

Two of the most‑talked‑about race competitors, Sandman and Pocoloco, had their voice actors revealed slightly later to round out the main competitor field:

• Masaaki Mizunaka voices Sandman, a resolute young man racing on foot to reclaim his tribe’s land.
• Kenichiro Matsuda voices Pocoloco, a farmer who joins the race after a fortune teller informs him he is experiencing a “one in five billion” lucky streak.

Their casting underlines how important these “non‑JoJo, non‑Dio” racers are to the way Steel Ball Run builds tension. This isn’t just a story about a protagonist and an antagonist; it is a whole chaotic field of weirdos, each with serious, top-tier talent behind the mic.
