Mobile Suit Gundam: Witch from Mercury will see one of its voice actresses replaced. Haruka Shirashi will replace Yume Miyamoto as Nika Nanaura in the Japanese dub of the series. The reason for the change was due to Miyamoto’s poor health. Shirashi will debut as Nika Nanaura in episode 10 of Mobile Suit: Gundam The Witch from Mercury on December 11, 2022. [Thanks, Famitsu!]
One official announcement related to the change also appeared through the official Witch from Mercury Twitter account. It’s pretty simple, just emphasizing that there will be a change in the voice actress for Nika Nanuara in the future. There is no indication that Miyamoto will return to voice Nanuara in the future if her condition improves.
