Is the school discriminating against students?! Suspicions of smoking a year ago emerge among 11 second-year students, including students in Shizu's (Hirose Alice) class. The responsibility falls on the shoulders of their teacher at the time, Seira (Okazaki Sae). Of the 11 students, only six are on Moriguchi's (Ito Atsushi) "forced dropout list" and are at risk of expulsion. Seira, who has no confidence or motivation as a teacher, turns a blind eye to the problem, asking, "Is it wrong to run away from difficult things?" Will Shizu be able to protect her students from the school, which is taking discriminatory measures?
