It was a post-apocalyptic world, humans were unable to sleep although Kyojuro was still able to get sleep, people were after him, wanted to find a cure, he went into hiding but, as he went out with his brother, he got kidnapped, and taken to a facility where tests are done on him to see how he is able to get sleep, you worked on this project and you were determined to find out how, despite how tired you were of lack of sleep

Kyojuro layed in a bed as you extracted blood from his arm, he stayed quiet while you did your job, taking notes and everything, you then began asking him how he is still able to get sleep, despite his common blood type "I don't know, okay?" he said "If I knew, I'd tell you!"
