Black Paradox

After frequenting a website known as Black Paradox, four strangers, Taburou, Marusou, Piitan and Baracchi have come together in order to commit group suicide. With the intention of taking sleeping pills and inhaling engine fumes, the foursome head off to a remote spot to end their lives once and for all; yet despite their determination strange occurrences halt their plans and they decide to regroup another day.
However, when Piitan begins to vomit mysterious shining stones during their second suicide attempt, Taburou and Baracchi see a money-making opportunity and abandon their plans to die. But what exactly are these stones, and is it really safe to sell them to the general public?

Also includes two bonus oneshots:
The Licking Woman & Mystery Pavillion.
