Plot

Behind the exterior of Mochizuki General Hospital resides the vigilante organization known as "Black Label". The team, made up of select hospital staff and local teenagers from nearby Mochizuki High School, task themselves with killing undesirable people, dubbed "cancers" of society, and to stop their spread of infection into society.

Characters

• Arashi Mikami (三神 嵐)
• The main male protagonist. A handsome but socially awkward high school student that belongs to the Black Label Organization, a vigilante group that deals with criminals the police are unable to.

During missions, he wears a bullet-proof motorbike helmet that covers his entire face.

• The main female protagonist. Arashi's partner and senior at high school. While at school she acts calm and proper, but can get short-tempered, especially towards Arashi. She has golden eyes, a lean body structure and a relatively large bust. She belonged to the Yakuza Kiba family, and her older brother Yuki tried to change it from the inside, which led him being killed on an arranged motorcycle accident, and she also got critically injured in the same accident. She was saved by the Mochizuki Hospital staff, which led her eventually joining the Black Label. She soon develops feelings for Arashi and she gets jealous when the other women or schoolgirls express their attraction toward him.
