After actually watching this third installment, the setting of 'no escape even when struggling' certainly had an impact. The concept of a rising demon targeting the depths of lustful lips, combined with the terrifying high-rise purgatory device, depicts the desperate female body in a frenzied state. However, while the climax expressions and humiliating elements are commendable, the breast vacuum part is somewhat disappointing, and throughout the series, the breasts and nipples are not sufficiently visible, leaving a sense of inadequacy. The reactions are generally subdued, movements are minimal, and there is an impression of limited highlights. In scenes where the triple assault of burning lustful flesh, nipple stimulation, and electric currents occurs, I expected the heat of the female body ablaze, but the intensity of the piercing climax and the hellish ecstasy leading to the heights of heaven didn't fully come through, making me wish for more intense developments. Overall, while series fans might find some enjoyment, it seems like a work with significant room for improvement.
