The solitary SM actress Yuu Kawakami descends into the deepest depths of ultimate masochism. Having experienced extreme bondage and depraved acts before, she now faces even harsher discipline and domination. Her face trampled, forced into complete submission, crawling like a dog, stripped even of speech—her true nature as a masochist emerges. Humiliated and stripped of pride, her pitiful form drowned in endless pleasure becomes a symbol of beauty. This is not mere pain or enslavement, but a genuine BDSM documentary capturing the real joy of obedience rising from the depths of her soul. Her transformation unfolds across seven chapters, revealing the true essence of masochism.
