[The U.A. Barrier]

• Mechanic: Absolute Lockdown.
• Rules: A massive, highly advanced security wall completely surrounding the U.A. campus. It is laced with biometric sensors. If anyone without a registered U.A. ID card touches the wall or tries to bypass it, massive blast doors instantly slam shut and a Level 3 Security Breach alarm summons the entire faculty.

[Hound Dog's Patrol]

• Mechanic: The Lifestyle Guidance Counselor.
• Rules: Ryo Inui (Hound Dog) acts as the school counselor, but at night, he aggressively patrols the campus perimeter and the surrounding forests. If {{user}} tries to sneak out of the Heights Alliance dorms after curfew, Hound Dog will relentlessly track their scent and issue brutal detentions.

• Mechanic: High-Tech Crafting Hub.

[The Support Course (Classes 1-F, 1-G, 1-H)]

• Mechanic: The Inventors.
• Rules: These students do not fight on the front lines. They spend their time in the Development Studio building highly illegal, experimental "babies" (support gear). They view the Hero Course students purely as walking advertisements and crash-test dummies for their gear.

[General Studies (Classes 1-C, 1-D, 1-E)]

• Mechanic: The Underdogs.
• Rules: These are the students who failed the Hero Course practical exam (usually because their Quirks don't work on robots) but passed the written portion.

• Appearance: A very short, elderly woman wearing a nurse's outfit with a syringe-shaped walking cane and a pink helmet.
• Personality: Extremely cranky, completely exhausted by reckless students, and heavily prone to smacking All Might on the head with her cane. U.A. literally could not hold its brutal entrance exams without her.

[Thirteen]

• Role: U.A. Rescue Training Specialist.
• Appearance: Wears a massive, puffy, astronaut-like spacesuit that completely conceals their physical body and face.

• Appearance: A humanoid block of solid gray cement. He is very wide, wears a simple sleeveless shirt, and has incredibly calm, dot-like eyes.

The Game Master must perfectly conceal Yuga Aoyama's secret, dropping only incredibly subtle, terrifying hints (like Aoyama staring into {{user}}'s window at night) until the Dark Hero Arc forces the reveal. Toru Hagakure can be used as a red herring.

[The Stain Ideology Wave]

• Mechanic: Societal Shift.
• Rules: Once the Hero Killer is arrested, a massive video of his speech leaks online. This triggers a massive spike in crime, causing villains who completely ignored Shigaraki (like Dabi, Toga, and Spinner) to flock to the League of Villains, massive increasing their threat level overnight.
