The TV anime Isekai Tensei Soudouki has revealed a new wave of cast members alongside its second key visual and second promotional video. The series is set to premiere on January 6, 2027 on TOKYO MX and BS Fuji.

New Cast Members

• Inoue Marina as Maggot, Baldo’s mother
• Koyasu Takehito as Ignis, Baldo’s father
• Kumagai Toshiki as Brooks, a classmate at the Royal Knights Academy
• Ozawa Ari as Teresa, Baldo’s childhood friend
• Yanagi Kohei as William, the fourth prince of the Kingdom of Mauricia
• Sakakibara Yuki as Franco, the second prince of the Kingdom of Sanjuan

Previously announced cast includes Kobayashi Yusuke as the lead Baldo, alongside Inomata Keishi (Oka Masaharu), Anzai Yukari (Seirun), Ito Ayasa (Serina), and Moroboshi Sumire (Silk).

Cast Comments

Inoue Marina (Maggot) said: “I went in thinking it was a typical mother role, but Maggot turned out to be so far removed from any ordinary mother that I was genuinely shocked. She shows every emotion imaginable — recording felt like playing a sport. It really demanded stamina and quick reflexes. I hope that energy comes through on screen!”

Koyasu Takehito (Ignis) commented: “Ignis is a strict father, but he can’t hold his own against his wife — which makes him kind of adorable. The show itself has a warm, soothing quality to it. Set the complicated stuff aside and just enjoy the comfort it brings.”

Kumagai Toshiki (Brooks) said: “Brooks is the mood-maker of the group. I loved him from the moment I read the source material, so getting to voice him is a real joy. He gives everything his all, even when things go sideways — please stick with him through it all!”

Ozawa Ari (Teresa) shared: “Teresa is a passionate woman with the strength of a knight. I threw in a lot of ad-libs during recording! The studio was lively from start to finish. This is a type of role I’ve never played before, and I’m having a great time with the challenge.”

Yanagi Kohei (William) noted: “William might seem like an arrogant, self-assured prince at first glance, but he also has the immaturity and competitive spirit that come with youth, which makes him relatable. I was careful to preserve his princely dignity at the same time. Recording was full of creative surprises.”

Sakakibara Yuki (Franco) said: “Prince Franco has a mysterious charm — androgynous, both strong and fragile at once. I’ll do my best to convey that delicate appeal to everyone. He’s cute and cool at the same time!”

Theme Songs

The opening theme will be 「異世界」 by Maverick Mom, while the ending theme will be 「Brand new day」 by Tokino Sora (Hololive). Both tracks are featured in the second PV.

ON, the drummer of Maverick Mom, commented: “This is Maverick Mom’s first anime tie-up, and I couldn’t be happier that it’s Isekai Tensei Soudouki. It’s the kind of story I love — not just epic battles, but deep dives into diplomacy and economics too. I believe ‘異世界’ is a worthy opening for this grand adventure.”

Tokino Sora said: “The idea of three souls sharing one body is so fresh and fascinating. I’m excited by how each soul shapes the protagonist’s actions and expands the story. I poured everything into singing this song so that his world and feelings come through clearly.”

Key Visual & PV

The second key visual depicts Baldo wielding a sword, with Oka Sanai, Oka Masaharu, and Seirun visible behind him. The second PV incorporates voice performances from all the newly announced cast members.

Story

Isekai Tensei Soudouki follows Baldo, a young man who carries two souls within him: Oka Sanai, a miserly warlord from feudal Japan, and Oka Masaharu, an otaku high school student from modern times. Drawing on their combined talents in commerce, martial arts, and knowledge, Baldo rises to the top of a fantasy world.
