Katagiri Yuuichi believes that friends are more important than money, but he also knows the hardships of not having enough funds. He works hard to save up in order to go on the high school trip, because he has promised his four best friends that they will all go together. However, after the class’ money is all collected, it’s stolen! Suspicion falls on two of Yuuichi’s friends, Sawaragi Shiho and Shibe Makoto. Soon afterwards, the five of them are kidnapped, and wake up in a strange room with a character from a short-lived anime.
Apparently, one of them has entered them into a “friendship game” in order to take care of their massive debt. But who was it, and why did they have such a debt? Could they have stolen the money from class to pay for entry into the game? Yuuichi and his best friends will have to succeed in psychological games that will test or destroy their faith in one another.
