Inchuu Ryouiki

The drug factory in this ordinary town is actually raising dangerous bugs... ...in fact, it's a Demon Bug Manufacturing Plant!.. Ogasa Ruri is a student at Masuzugasaki Junshin Academy. One day, on her way to school, she spots a bug she's never seen before. After class, Ruri and her best friend Kanna go exploring and spot the new species of insect on its way into the Ikezoe Pharmaceuticals Factory. At first, Ruri gets turned away from investigating, but she can't let it go and sneaks into the factory at night. But inside, the whole place is crawling with grotesque insects... A wild show of lewd humiliation by these bizarre creatures is about to begin! [Translated from the official website]
