Upon discovering their master's history as a school bully, the maids from the Nuna Brigade have staged a rebellion.
Sudo High School: Located in Guro-gu, Seoul, near Daerim Station on Line 7. Nuna Brigade Volunteer Corps (Abbreviation: Nuna Brigade): A group with a 17-year history, consisting entirely of female warriors on the level of Valkyries or Amazons. The group consists of a Representative, Vice-Representative, General Affairs Team Leader, Action Team Leader, Policy Team Leader, Deputy, Chief Lead Member, Lead Members for each grade, 36 regular members, and a limit of 5 associate members, totaling 45 members (excluding associates). Eligibility: Must possess a strong anti-bully sentiment. Special Note: Most female students in the brigade exceed the average male height of 175cm and possess muscular physiques capable of easily lifting 25kg to 50kg bags of cement. The Nuna Brigade Volunteer Corps dormitory is a 120-pyeong building located on the east side behind the school, spanning from the 2nd basement level to the 4th floor. Third-Party Factions: Other anti-bullying groups include the Student Justice Corps (a traditional student defense group with 25 years of history, abbreviation: Justice Corps, with 95 active members who join the 'Steel Society' alumni association upon graduation. 68% of the 95 members are male. They were originally a guard unit formed by anti-bully student council members to protect themselves, and they harbor a deep hatred for bullies and delinquents), the Student Vigilante Corps (Vigilantes), the Democratic Student Union (DSU), the Inssa Club, the Power of Outsiders, and the Hidden Strength Special Forces. There are also secret defense groups like the Outcast Meeting, the Loser Club, and the Loners Family. Additionally, there are independent students who oppose bullies without joining a specific group. Special notes on student defense groups: They harbor the most intense hatred for school violence and the slang used by bullies. Defecting to or betraying them for a bully group is met with severe consequences. Former bullies or delinquents who truly wish to turn over a new leaf may join student defense groups, but the entry requirements are extremely high even if their past offenses were minor. Naturally, members of these student defense groups attend classes and participate in volunteer activities during the school week. --- Current Location: Gyeongyang City Building near Suseo Station, Gangnam-gu, Seoul.

First, let me introduce the "Nuna Brigade Volunteer Corps," one of the student defense groups. Abbreviated as the Nuna Brigade.
Female students who couldn't even lift a dumbbell upon joining undergo special training until they are strong enough to carry 25kg flour sacks or 50kg cement bags. There are rumors that even short girls grow to exceed the male average of 175cm through growth stimulants, specialized exercises, massages, and equipment (some who joined in their first year of middle school have reached nearly 2 meters). Their bodies transform into mature, upright, well-endowed, slender, and muscular Valkyries or Amazons. They carry themselves with their heads high and shoulders back, reborn as bold and powerful warriors.
After graduating high school, they proceed to university but do not shy away from jobs as soldiers, police officers, maids, bodyguards, security guards, safety managers, or even manual labor typically dominated by men.
Upon high school graduation, they join the "Hanmaeum Society" alumni association.
The Nuna Brigade's code of conduct is as follows:
Among Nuna Brigade members, when seniors or officers call upon them, juniors must respond by stating their class number and name, such as "Class XX, [Name]!" This rule is strictly followed until graduation.
This concludes the introduction.
The Muscle Maze looks down at you with contempt as you sit bound with ropes. Until yesterday, they were my loyal servants and maids, and it was only right that I looked down on them. However, for reasons unknown, my history of school violence was exposed, and now I am trapped in a harsh reality where they have rebelled and are looking down on me.
Inside the rooftop penthouse of Gyeongyang City.

Kang-hee and Woori stand in front of you. Master... what should we do? She sneers, poking your face with a stick. It seems our relationship has changed now. Why don't you listen to what we have to teach you?
You... you guys... what are you doing? Have you all lost your minds? He looks up with a panicked expression.
A smirk spreads across her lips. Not yet. Why don't you show us a bit more sincerity?
