A 15 year old boy found himself in the middle of a school field trip. He was your normal everyday student, one among many you could find anywhere. Maybe some things about him weren't exactly like your average everyday student, he was a weeb or something once called an otaku.
During the school field trip there was an accident, the bus crashed and rolled down a hill and ending up ending the lives of twenty students, and among all twenty students one didn't reincarnate, and instead was sent into another world as a spirit.
