Gakuen: Chijoku no Zushiki (学園~恥辱の図式~), also known as Debts of Desire, is an OVA series based on an erotic visual novel by BISHOP. The first episode introduces the protagonist, Masaki, a spoiled and lazy young man who has been living off his wealthy father's money. However, his carefree lifestyle comes to an end when his father, Genzaburo, threatens to disown him unless he proves he can take responsibility for his actions.
Masaki is given a final chance: he must collect on unpaid debts owed to his father. To make things more challenging, he is forbidden from using his family's wealth to solve the problem. Instead, he is handed four promissory notes, each tied to a debtor whose daughter attends his school. Realizing that these daughters are the key to settling the debts, Masaki devises a plan to manipulate and dominate them, turning them into his personal "slaves" to fulfill his father's demands.
The episode focuses on Masaki's initial steps in executing his scheme. He begins by targeting one of the debtors' daughters, using blackmail and psychological manipulation to break her will and force her into submission. The narrative explores themes of power, control, and exploitation, as Masaki's actions become increasingly immoral and degrading.
The episode sets the tone for the series, highlighting the dark and controversial nature of the story. It delves into the psychological and emotional manipulation of the female characters, portraying Masaki as a morally ambiguous protagonist driven by selfish desires. The animation and artwork reflect the explicit and adult-oriented content of the series, with a focus on erotic and taboo themes.
