The official Red River website has published an Episode 1 character relationship chart and a map for the story’s setting.
Fans can view the chart and map on the official website’s Episode 1 page, under the MAP section.
The story follows Yuri, who is suddenly summoned to the Hittite Empire in the 14th century BC. The newly released chart introduces the characters surrounding her in the story.
AniHeat's take: Worth noting for fans who want a quick guide to the characters and setting before exploring Episode 1 of Red River, including its 14th-century BC Hittite Empire backdrop.
