You can watch the Honkai: Star Rail Myriad Celestia “Stoneheart’s Oath Ring: Both Ends of the Scale” trailer here:

It’s also available in Mandarin Chinese, Korean, and Japanese. The individual cast list is in the description.

The video is rather lengthy at over three minutes long. It takes place after the Penacony story and thus contains spoilers if you haven’t completed it yet. In the trailer, Diamond has summoned all the Stonehearts to discuss how they would punish Aventurine, who had to smash his Cornerstone as part of his ploy to take Penacony for the IPC.

Here is the English cast of the Stonehearts (we know so far) in Honkai: Star Rail:

  • Aventurine: Camden Sutkowski (Rhysand in For Velaris)
  • Jade: Faye Mata (Astolfo in Fate/Apocrypha)
  • Obsidian: Erin Yvette (Arlecchino in Genshin Impact)
  • Opal: Paul Castro Jr. (Ryota Miyagi in The First Slam Dunk)
  • Pearl: Cat Protano (Misha in Honkai: Star Rail)
  • Sugilite: AJ Beckles (Wind Maki in Anonymous;Code)
  • Topaz: Sam Slade (Anby in Zenless Zone Zero)

Here is the Japanese cast:

  • Aventurine: Kengo Kawanishi (Mikazuki in Mobile Suit Gundam: Iron-Blooded Orphans)
  • Jade: Kotono Mitsuishi (Sailor Moon/Usagi Tsukino in Sailor Moon)
  • Obsidian: Sumire Uesaka (Saeko and Nanoha in Yakuza: Like a Dragon)
  • Opal: Daisuke Kishio (Rokurou in Tales of Berseria)
  • Pearl: Kiyono Yasuno (Hoshiguma in Arknights)
  • Sugilite: Hiroki Takahashi (Emet-Selch in Final Fantasy XIV: Shadowbringers)
  • Topaz: Yoshino Nanjo (Lala Shonai in Yatogame-chan Kansatsu Nikki)

It’s unknown which of the Stonehearts will appear as playable in the future. There’s always the chance that, like with Signora of the Fatui in Genshin Impact, some of these characters will die in the story and become “unavailable” in the gacha.

Honkai: Star Rail is readily available on the PS5, Windows PC, and mobile devices.
