An aphrodisiac experiment to set up Nagisa who has never had a vagina. Have them take an aphrodisiac that has the effect of increasing libido, "toilet," "closet," "clothes dance," etc. The dark, narrow, stuffy closed space fuels fear and sharpens sensitivity. And finally the reason collapses! Drowning in dangerous pleasure, screaming with a spectacular acme face, crazy, turbulent Iku! !!
