The cp-191 is a hibernation drug, developed for a manned Mars investigation project.[1]

Principles[]

Originally developed for a manned Mars investigation project that never got anywhere, cp-191 is powerful enough to put a grown man to sleep for three months. It also allows for the brain's signals to become too flat, preventing anyone from waking up the person who ingests the drug, as well as preventing mind-related espers from poking around the ingester's brain.[1]

The drug was used by Matsusada after he realized that he might be already affected by Agitate Halation, putting him to sleep, much to the inconvenience of Yomikawa Aiho and Stephanie Gorgeouspalace, who were trying to capture him.[1]
