START-453 I'm looking for Yuna Ogura.

Yuna Ogura's 8th anniversary work is a shocking and controversial piece!? SODSTAR's Yuna Ogura suddenly disappears. When the reporting team tracks her down, they discover she has joined a mysterious cult that believes sex can bring "rebirth." During the extreme rituals, she gradually loses her sanity and is consumed by madness and pleasure. What is the truth hidden behind this?
