Gundam: The Witch From Mercury, the latest anime series of the Mobile Suit Gundam franchise, introduced the anime's first female protagonist as well as new elements never featured in previous Gundam shows. However, it looks like a shake-up has been announced as a major character in Suletta's story has had to leave the anime but will be replaced for the anime's future episodes.
The new character who will be getting a new voice actor is Nika Nanaura, an engineer who becomes Suletta's ally thanks to her passion with the Aerial Gundam that the heroine uses throughout the series. According to the official website of Gundam, here's the character description of Nika: "A second-year student in the mechanical department, who belongs to Earth House. She loves mecha, and is very curious about Suletta's Gundam Aerial. Nika has outstanding maintenance skills, and is proud of herself for customizing Chuchu's Demi Trainer."
According to the official Twitter account for Gundam: The Witch From Mercury, the previous voice actor for Nika Nanaura, Yume Miyamoto, will be exiting due to a "poor physical condition", and voice actor Haruka Shiraisha will be taking over her role on December 10.
