A magic truck appeared 100 meters on the house of an 18 year old boy. Thankfully the parents are on a bussiness trip so he died alone because of a magically appearing truck. Then the boy is reborn as a baby of a normal family. But later will get drafted to war due to the world being in an apocalypse setting.

(Alternate title I was thinking about : Surviving As An Extra in an Apocalypse, War, Otome and Gal Like Game I don't Even Know Of.)
