DASS-247 Drug squad investigator Misaki is drugged and broken by informant Kurokawa, losing her sense of justice.

Misaki, a drug squad investigator with a strong sense of justice, suspects a leak and rushes into a hideout alone, where she subdues the men but is knocked out from behind by a woman. When she wakes up, she is tied up by Kurokawa, the informant, who uses supernatural powers and synthetic drugs to make her feel pleasure. Misaki loses her resolve and turns lewd.
