Kaede Kurenai held the position of Head Diver. She employed potent psychic abilities, specifically dowsing, which proved invaluable in her operational duties. She possessed a past connection to Mugito Mamon and the Superhuman Federation, though the precise nature of this association is undefined. As Shou Yanagi's partner, their professional relationship deepened into a personal one. Kaede became pregnant, and the couple married shortly before a major final confrontation. However, Kaede contracted the Algernon affliction. This infection drove her to kill both Shou and herself. Despite this tragic conclusion, their unborn child survived the incident. The child was rescued by a D-Type Hunter, identified in accounts as a "lizard girl."
