Every day seemed dull to the young girl, who, on a whim, visited a basement dealing in illegal drugs. However, what she inhaled there was pure toxic gas. Amidst the agony of the poisonous fumes, she clung to pleasure as her salvation... Yokomiya Nanami, debuting about half a year ago, expresses the hellish pain caused by toxic gas through her entire body. The AV that currently embodies all of her body, mind, and eroticism is "Toxic Gas / Aphrodisiac DE Grueling Brainwashing Experiment." It's a great masterpiece!
