Why did the unemployed middle school student die?

According to the query of the app, I know that I didn't die in the animation "Unemployed Cycle". Grerat is the second daughter of the Grerat family. She likes practical jokes and has a high talent for divination. Unemployed reincarnation tells a series of stories about a 34-year-old virgin Janet who was hit by a truck and woke up to find herself in a different world of sword and magic.
