The fifth installment, "A living hell so extreme that even the word 'madness' feels mild—choking torment," is finally here! Miwa, a prim and beautiful teacher, visits the home of her truant student Sayo in an attempt to bring her back to school. But this visit becomes a humiliating ordeal and the beginning of a nightmare for Miwa. As she tries to persuade Sayo to return to class, she's shocked by an unexpected confession—Sayo is a lesbian who's deeply in love with her. What's more, Sayo is obsessed with choking and explicitly demands to strangle Miwa until she passes out. Overwhelmed and confused, Miwa complies, strangling herself under Sayo's command. Her eyes roll back as she loses consciousness. When Miwa regains awareness, Sayo tightens her grip again, inducing repeated choking sessions. Gradually, Miwa begins to experience pleasure in the loss of consciousness. As the teacher succumbs to this twisted ecstasy, her body betraying her dignity, her helpless fainting spells become the ultimate source of Sayo's delight. *Note: Some parts of the video may appear distorted; this is due to the original master material.
