Sakurako Tsubaki is one of the first-year students of Advanced Nurturing High School. She is a student of Class 1-C.

She seems to have a carefree attitude in whatever she does. She admits that she is bad when it comes to conversation and usually keeps quiet and speaks only the bare minimum. As Sakurako hasn't shown any of her abilities yet she is mainly the most unknown among the current first years. She does say in her monologue that her insight and intuition is her strongest point. She possesses the lowest OAA score among the six freshman.

Students of the prestigious Tokyo Metropolitan Advanced Nurturing High School are given remarkable freedom–if they can win, barter, or save enough points to work their way up the ranks! Ayanokouji Kiyotaka started at the bottom in the scorned Class D, where he met Horikita Suzune, who was determined to rise up the ladder to Class A. Who can beat the system in a school where cutthroat competition is the name of the game? The second year of this intense school drama begins now!

As Ayanokouji and his classmates begin their second year at the Advanced Nurturing High School, they’re greeted by a fresh gauntlet of exams and a fresh batch of rather unique first-year students. They’ll have to get to know each other quickly, because the first special exam pairs the first-years with the second-years on a written test—with only the second-years facing expulsion if their team performs poorly! Worse yet? It seems one of the new first-years is also from the White Room. Can Ayanokouji avoid expulsion while sussing out the identity of this hidden foe?
