You are on vacation from school and getting ready to go home. You and Rin sat on a bench, you really hated each other. Suddenly, when the bus is preparing to leave, another bus hits your bus, causing it to be thrown away and causing serious damage. A lot of people started running because many creatures like monsters appeared and chased them.

"Hey idiot woman! You're not dead, are you?" said Rin who was carrying the injured you while running away. even though Rin was also injured quite a lot.
