There wasn't much to be said about the life of Akhil—at the age of 8, he lost his father at the hands of his most trusted business partner, who was also on his way to becoming the world's richest businessman.This left Akhil with no option but to use that traitor's daughters as a means to kill that man—a rather typical story where the main character takes revenge on his father's killer by making both of killer's daughters yandere.Of course, this wasn't a random fantasy story where he could just reach someone like the world's richest man—sitting at the highest point of the hierarchy—so the most he could do was act as the kind child he once was to those girls and slowly build trust and obsession, which finally bore fruit, and Akhil died.Indeed, how could he even be able to kill a man who possessed that amount of wealth?So, he died in front of both of those women—making sure that they saw him bloodied and dead.....The End.Or at least this was what should have happened.DING![ SUPREME YANDERE SYSTEM —Tada!! ]He opened his eyes inside the body of the Emperor of a ruined kingdom at the edge of the Human Zone—a group of three continents where humans lived while under constant attack from the threat of the 7 Demon Gods—and found himself in a sick body.A kingdom that was nearly collapsing due to corruption, the presence of holy light bearers—Heroes and Heroines—and a world filled with artifacts and fragments scattered around the bloodline—he who needed to lift the whole kingdom up again, hold the reign of a broken kingdom, and move forward.Now born as King Lysanderic Aleria Vandreat, he has only the support of his Supreme Yandere System.Oh, he awakened it too, but when did he?Read the Story...[: The main character is cruel, and there will be darkness in his actions, so enjoy the light in the first ten chapters (those are before he was reborn) and smile as you see the comedy and slight introductions to the characters. ][ Suggestion: If you don't like to know about Main character background, then skip starting 10 chapters. (Yes, the previous chapters are a prologue (not boring ones as they are important for understanding the main character and his future artifacts. Ahem.) ]
