Three sisters who weaponize paper solve mysteries that keep dragging them toward a conspiracy nobody warned them about. The show treats its premise with complete seriousness, building a world where the ability to control paper becomes the lens through which entire histories rewrite themselves. By the end, you realize the real mystery was never the case, it was whether these three could stay together after learning what they're actually protecting.
Nenene Sumiregawa is a novelist trapped by creative exhaustion, haunted by the disappearance of a close friend. Her life shifts when she meets three sisters from Hong Kong: Anita, Maggie, and Michelle, whose seemingly impossible ability to manipulate paper transforms them into formidable investigators. The sisters operate a detective agency that handles the strange and dangerous cases no one else will touch, cases that orbit around books and the secrets they contain. When Nenene joins their operation, an unlikely family emerges from circumstance and shared purpose. Together they uncover a web of conspiracy far larger than missing persons and mysterious manuscripts. A shadowy figure orchestrates events across the globe, using knowledge locked within books as a tool for world domination. As the group travels internationally pursuing clues, they're forced to confront enemies willing to destroy everything for power. The tone balances quirky chemistry between characters against genuine peril. What begins as casual detective work becomes an international battle where loyalty and sacrifice matter more than any single victory. Readers and action lovers both find something here: character-driven storytelling wrapped around globe-trotting adventure.
