Cast Reveal for Bitchu Matsuyama Castle Team in "Oshirobots"

The original content project from MIXI_ANIME, known as Castle Combination Oshirobots, has just shared some very big news regarding its latest cast additions. According to the recent announcement, the talented Miho Okasaki will be taking on the role of Katsukiyo, who is the main pilot for the massive Osirobot Bitchu Matsuyama Castle. Joining the team is the veteran voice actor Yoshitada Otsuka, who will be portraying the Shirodama (warlord) Katsutani Yamada. This project is quickly becoming a favorite for mecha fans who are looking for something totally fresh in the genre.

In the promotional material released, we can see the characters side-by-side: Katsukiyo (voiced by Miho Okazaki) and Hoya Yamada (voiced by Yoshitada Otsuka). The character designs look quite sharp and properly reflect the historical inspirations behind them. For those who want to see all the details, make sure to view the visuals in high quality to appreciate the artwork.

Getting to Know the New Characters

Katsukiyo is introduced as a young master of Bicchu Kagura, showing a lot of dedication to his craft. He is written as a character with a very deep sense of righteousness, someone who will never abandon his friends no matter how tough the battle gets. On the other hand, we have Yamada Hoya, based on a historical figure who famously reformed the finances of the Bicchu Matsuyama domain. In the story, he is known as the "Bicchu Saint," a wise figure who believes in "Sincerity and Compassion." It is quite interesting how the creators are blending real history with giant robot action.

Along with this cast reveal, a special PV featuring the voices of both characters has been released online. The marketing for this series is also very unique; it has been decided that this PV will be aired at actual historical locations like the castle tower of Bitchu Matsuyama Castle in Okayama, as well as at Shiromachi Station and the Takahashi Tourism Exchange Center.
