Aoi Ito

When a man attempts to catch a serial killer to collect a reward and provide for his family, his daughter fears the worst after he suddenly vanishes.

The bodies of young boys were found in six cases. Shiro Sakaki, a professor considered Japan's leading expert on butterflies, turns himself in. He has recorded everything in a report published on the Internet, from his motive to the process of his creation. The interrogation proceeds as if tracing his distorted record, leading to a sensational suspense story where beauty and madness intertwine.
