About Red River

Red River (天は赤い河のほとり) arrives as an action anime by Tatsunoko Production (2026), and the premise is easy to summarize. The setup: After an unexplained hand drags her beneath a puddle, modern Japanese teenager Yuri awakens in the Hittite Empire of the 14th century BCE. Thrust into a deadly struggle for the throne, she joins Prince Kail to battle assassins, outwit royal conspiracies, and survive a world at war.

Further in, as her exploits earn her renown as the goddess Ishtar, Yuri must choose between her old life and an uncertain future.

As an action title, fight choreography, pacing and sound design carry much of the weight. Voice work is led by Wataru Katou as Kail Mursili and Mirai Tachibana as Yuri Suzuki. Think of it as a pick for viewers who like fast, high-impact fights. With 19 episodes so far, there is enough room for the story to develop.

Production & Appeal

Animation is handled by Tatsunoko Production, so the studio's house style defines how Red River looks and moves on screen. The action focus matters here: fight choreography, pacing and sound design carry much of the weight. Its 6.2/10 score suggests opinions are split, so it suits viewers who already like the genre. Voice casting, including Wataru Katou as Kail Mursili, adds to the appeal for fans who follow seiyuu. Released in 2026, it competed with that season's other new series for attention.
