Hiru

A 21-year-old woman named Youko has disappeared to escape her past. She moves from apartment to apartment when no one is home, living unnoticed among everyday people. At first, her life is free and thrilling, but she soon realizes she is not alone. There exists a hidden society of people like her—some are fugitives, others have rejected normal life for various reasons. They refer to homes as nests and engage in violent conflicts over territory, often resulting in deadly feuds. Youko believed she was the only one, but now she must navigate this dangerous, secret world.
