In this world, there are orphans who preside over swords, there are girls who are alluring in red, there are generals who protect the country, there are masters who die generously, and there are emperors who shed tears while drinking alone. There is a person who was a nobody before his death, but thousands of people admire him after his death, but no one behind him sheds a tear. Until the protagonist split the world with a knife, leaving behind countless stories!
