Shukaido

As the team's physician, this character often remained in the background, possessing a calm, intelligent, and polite demeanor. He harbored a deep affection for Mokuren, mirroring the feelings of the other male members. While maintaining good friendships with Gyokuran and Shion during their college years, he frequently attempted to mediate tensions. Remarkably, he developed a life-saving vaccine for the fatal virus, which ultimately left only himself, Mokuren, and Shion as survivors.
