Tokyo, Japan – [Insert Current Date] – The highly anticipated anime adaptation of Chie Shinohara’s beloved shōjo manga, Red River (Sora wa Akai Kawa no Hotori), has officially announced two pivotal additions to its voice cast. The series, which premiered on July 7th on NTV’s "AnichU" programming block and subsequently on BS NTV on July 8th, with Crunchyroll simulcasting the episodes, will feature the talents of Sōma Saitō as the formidable Egyptian general User Ramses and Shun Horie as the young Hittite prince Juda Haspasrupi. These new cast members are set to bring to life key characters in the epic historical romance that has captivated readers for decades.
The official website for the Red River anime unveiled these exciting casting choices on Monday, sending ripples of anticipation through the dedicated fanbase. User Ramses, a character described as a free-spirited Egyptian general and a formidable rival to the protagonist Kail, will be voiced by Sōma Saitō. Known for his versatile performances in a wide range of anime, including roles in Jujutsu Kaisen and Fruits Basket, Saitō’s portrayal is expected to capture the commanding presence and complex nature of this significant figure.
Complementing this, Shun Horie will step into the role of Juda Haspasrupi, the sixth prince of the Hittite throne. Juda is depicted as a young royal who deeply admires Kail and harbors a growing suspicion towards his mother, Nakia. Horie, whose notable roles include characters in Horimiya and My Hero Academia, is poised to imbue Prince Juda with the youthful vulnerability and burgeoning political awareness that define the character.
A Deep Dive into the Characters and Their Voices
The inclusion of User Ramses and Prince Juda marks a significant expansion of the anime’s cast, introducing characters who will undoubtedly play crucial roles in the unfolding narrative.

User Ramses: A Rival of Epic Proportions
Sōma Saitō’s casting as User Ramses is a significant development. User Ramses is not merely an antagonist; he is a powerful military leader and a central figure in the intricate political landscape of ancient Egypt. His "free-spirited" nature suggests a character who operates with a degree of autonomy and conviction, making him a compelling foil to Kail, the prince of the Hittite Empire. The dynamic between Kail and User Ramses is a cornerstone of the romantic and political tension within Red River, and Saitō’s vocal prowess is expected to deliver a performance that is both commanding and nuanced. Fans will be eager to hear how he portrays Ramses’ ambition, his strategic mind, and his personal motivations that often clash with Kail’s interests.
Prince Juda: A Glimpse into the Hittite Court
Shun Horie’s portrayal of Prince Juda Haspasrupi offers a different, yet equally vital, dimension to the series. Juda represents the younger generation within the Hittite royal family, a character who is both impressionable and observant. His admiration for Kail hints at a potential ally or a character who could be swayed by the protagonist’s actions. However, his suspicion of his mother, Nakia, suggests a burgeoning awareness of the political machinations at play and a potential internal conflict. Horie’s ability to convey youthful earnestness and developing maturity will be key in bringing Juda’s arc to life, making him a character that audiences can connect with as he navigates the complex world of Hittite politics.
