LADA Decensored — AI mosaic removal version. Naho is a serious teacher with a very strong sense of justice. After witnessing Kaho, an excellent student, being bullied by male students, she reported it to the principal, and disciplinary action was taken. Consequently, the students held a grudge against her, and Naho herself became their target. One day, Naho was called to the nurse's office, where she was shown a video of Kaho being teased and threatened that it would be leaked... Driven by her strong sense of justice, Naho decided to become a substitute to protect Kaho and let the students play with her. However, gradually, even Kaho became involved, and they both transformed into "meat toilets."
