Season 2

Several years have passed since Yamaguchi left Shirokin Gakuen, which eventually closed. Yankumi has faced hard times in the years that followed, teaching a new cohort of younger students ill-suited to her approach. Change arrives on a notable day - a bad hair day that, with a twist, takes a turn for the better. Mr. Sawatari Goro, Shirokin's vice-principal, is in need of a teacher at his school - and not just any teacher: he specifically seeks Yankumi. The destination is Kurogin Gakuen. Upon arrival, she finds happiness, only to learn that she must manage another Class 3-D - this time meaner and more violent. As ever, she must conceal her background or she'll lose her job. She does her best to be kind to every student, but it seems the challenge is greater than ever, for the students are worse than the word worst. How will she face them? Is this a new challenge?
