――My name is Yamada.

I'm your average student who was hospitalized because of broken arms. However, I'm also suffering from a rare disease which causes "severe pain in my testicles if I don't ejaculate every three hours".

There is a rumor that the hospital where I'm admitted only has "nurses with the worst personalities". This is more than just a rumor, it is a fact... As I have seen with my own eyes, such a terrifying reality.

Manufacture of illegal drugs.
Strong ties with criminal organizations.
Undercover police investigation.
Isolation ward.
6 million yen a year just for ejaculating.

In this place that I don't know where various people's intentions get mixed up, I found myself sucked into a whirlpool.

What is right and who is wrong?
What is sin and who will punish it?

Now that I have found the answers to these questions, will I be able to get out of this hospital safely...?​
