About Red River

Looking for background on Red River (天は赤い河のほとり)? This action, adventure and drama series by Tatsunoko Production (2026) starts out like this. What the story covers: 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 fight assassins, outwit royal conspiracies, and survive a realm at war.

From there, as her exploits earn her renown as the goddess Ishtar, Yuri needs to choose between her old life and an uncertain future.

In an action series like this, fight choreography, pacing and sound design carry much of the weight. Kail Mursili (Wataru Katou) and Yuri Suzuki (Mirai Tachibana) are two of the characters you will meet early. This one is best suited to viewers who like fast, high-impact fights. The run is 19 episodes so far, so you know what you are signing up for.
