On the day the empire fell to rebellion and invasion from another world, Valen met his end alongside his sister, the Emperor. But when he opened his eyes again, he found himself 40 years in the past. This time, he vowed to do whatever it took to prevent the world’s destruction and protect the Emperor. And his solution? To live an even wilder life than before. “If I was a scoundrel in my past life, then this time… I’ll be the ultimate menace!”(Source: Ridibooks, translated)
