忌火起草

A new and mysterious drug known as "Vision" has been hitting the streets of Japan, being a hit to the young people, especially to those studying in university. The drug, if and when taken, allows the users to see visions from a user's perspective while being high, created from a mysterious flower called Imabikisou. Players play a university student named Hiroki Makimura, who gets together with fellow student Manami Hayase and a few other students when they heard news reports of students being mysteriously killed with horrific burns on their bodies.

The two later investigate a mansion that's believed to be linked to the drug's creation and to Imabikisou after some of their classmates in university begin to die after taking Vision.
