A twenty-six-year-old office worker finds her reason for living in supporting Tokino Kaede, a young and handsome voice actor. What begins as enthusiastic fandom—buying tickets and merchandise, watching his streams and anime appearances—gradually curdles into an obsessive urge for possession. She becomes convinced that "harmful otaku" are swarming around her beloved celebrity on social media, acting as parasites who threaten his well-being. This conviction sparks a decisive shift in her behavior: she resolves to protect Kaede from these perceived threats, stepping across the line from devoted fan to self-appointed guardian. The story unfolds within the contemporary Japanese voice actor fandom, exploring how digital spaces like social media can amplify and distort parasocial relationships. As her actions escalate, the narrative questions whether her protection is actually a form of harm, forcing readers to consider where admiration ends and dangerous fixation begins. The series traces her psychological journey from ordinary supporter to someone whose love has become a consuming force, examining the dark side of celebrity worship and the blurred boundary between devotion and delusion.
