Part 4/8:
Once Nano's true rebellious nature is unveiled, she embarks on a mission to challenge and dismantle the oppressive rules governing Pantana Wataya. With a willful laugh, she defies the authority symbolized by the lipstick—not just wearing it but flaunting it in front of her classmates. Under her influence, the atmosphere begins to shift, to the dismay of the teachers.
Despite facing brutal punishments, including forced memorization of the 427 rules and confinement in the ominous "repentance room," Nano remains unfazed. Her laughter in the face of hardship becomes a rallying cry for the other students, who tentatively begin to embrace the idea of rebellion.
