Reincarnation

Well, the introduction shouldn't be too entertaining or too funny. Otherwise, it would be easy for me to go off topic. Be more traditional - The story takes place in a world hundreds of years later, where humans have their own system and way of life due to the invasion of alien species. The protagonist, who has been sleeping peacefully for hundreds of years, struggles in it after waking up. －－－－－－－－－－－－ If you don't write well at the beginning, don't worry if you can. I will write more exciting things later.
