Three sisters inherit a god nobody asked for, and suddenly they're responsible for what a weapon does to the world. The show treats this like a real problem, not a power fantasy, but a burden that splits them apart every time they have to choose who gets hurt. It's a fable about power and consequence wrapped in 90s sci-fi that asks what you owe the people around you when you control something that can destroy them, and never pretends there's a clean answer.
Three sisters inherit more than they bargained for when a massive ancient deity awakens on a remote Pacific island and follows them home to Tokyo. Minami, Ushio, and Yuuhi Shimabara suddenly find themselves responsible for Ranga, a god-like being that towers over the city and defies understanding. The creature's arrival throws the capital into chaos. Some see it as a miracle worth protecting at any cost. Others view it as a threat that must be eliminated. Government agencies, corporate interests, and religious fanatics all converge on the sisters, each with their own agenda for controlling or destroying the god in their care. The sisters must navigate impossible choices as they learn what Ranga truly is and what it wants. Their bond with each other becomes their only anchor as the world around them fractures. Ranga itself remains enigmatic, neither fully hostile nor completely benign, forcing the trio to question whether they can trust something so fundamentally alien. Adventure and dread intertwine as personal stakes collide with forces far beyond their comprehension, and the sisters discover that inheriting a god means inheriting the burden of its secrets.
