Class D and the School Comedy Setup
Spoiler note: This PopRot section covers the school-comedy setup, episode topics, and character dynamics of The Glass Mask Year 3 Class D. It stays spoiler-light because the shorts are gag-driven.
Class D is the main social arena where the cast can replay theater-drama intensity through school-life sketches.
