Joshikousei Kyouhaku Inkou Nisshi: Nakayoshi Kyonyuu Pet Kyousei Zecchou Akume Ochi

Yasukata Ueda serves as the deputy principal of an all-girls school, a position that constantly surrounds him with youthful beauty yet offers no outlet for his mounting desires. Consumed by frustration and increasingly fixated on fantasies involving his students, his daily life becomes an exercise in quiet desperation. However, everything changes one afternoon when he overhears hushed voices drifting from the student lounge. Investigating the sound, Ueda stumbles upon two girls sharing a secret, intimate moment together. Recognizing the situation as both scandalous and opportunistic, Ueda quickly pulls out his smartphone to record the encounter before slipping away undetected. With incriminating video evidence now securely in his possession, he holds absolute leverage over the unsuspecting pair. The power to blackmail them ignites a dark ambition within him, though he realizes he must carefully choose which girl to target first rather than confronting them both at once. As the pieces of his manipulative scheme click into place, Ueda’s remaining moral boundaries collapse like falling dominoes, setting him on an irreversible path driven by coercion and unchecked desire.
