Cleaning & Clearing (C＆C), is one of the clubs at Millennium Science School.
Officially, C&C is a simple maid club. In reality, the club is Millennium's elite special operations unit, tasked with removing any potential threats to the school. As a result, they often work in conjunction with the school's student council, Seminar.
Being a faction tag, this should only be used when all members of the group are present and equally in focus, with the exception of Asuma Toki, as she did not appear in the story as a member initially.
The number in parentheses is their agent callsign.
