DLDSS-545 Naho Sumi, Kaho Hanamori

Naho, a serious and righteous teacher, witnesses an excellent student, Kaho, being bullied by male students. She reports it to the principal, and disciplinary action is taken. In retaliation, Naho becomes a target of the students' resentment. One day, Naho is called to the infirmary, where she is shown a video of Kaho being harassed and blackmailed with its dissemination. To protect Kaho, the strong-willed Naho offers herself as a substitute and is exploited by the students. Gradually, Kaho also becomes involved, and they both transform into human playthings.
