The Academy’s Deceased Ate It All - Chapter 4: World Tree.

Where there is light there shall be darkness

Hero? Nahh I'm the demon.

In a world where the demons are looked on as the incarnation of evil, the human-demon war raged on across the whole continent.

The Seraphims, protector of humanity, and the Demon lords who rule across all demonkind. Amidst all the chaos, Simon was reincarnated as the lowest ranking demon noble.

A brutal world where the strong feeds on the weak, eat or be eaten, kill or be killed. A demon far off from humanity….a dream unfulfilled in his previous life will be achieved in this life. Taking on the moniker of Laplace, he destroys all his enemies and rise over them.

Su Chen lost his sight in an unfortunate, unanticipated encounter. He was unwilling to give up despite suffering one of the most tragic fates possible in the human realm and fought on. Su Chen wants to use his own efforts to create a completely new destiny, both for himself and for mankind!

An era where the desperate, miserable, and tragic tale of the six heroes who sealed the Dark Mage, who sought to destroy Maple World, became the favorite legend of children.

“The Cygnus Knights have fallen, the Resistance has collapsed, the Cross Hunters have been destroyed, and the adventurers have been annihilated. And the six heroes are dead.”

An era where no one dared to resist the reappearance of the Dark Mage and his followers.

“You are the only one left, El Paume. You’re the last adventurer.”

In that era, there was an adventurer who continued to fight until the end.

Lou Yao Yao wasted her life fighting over a man, only to find out he wasn’t worth it in the end. Because of this man, she accidentally killed her rival in love, and even ruined the man who had always been watching over her.

Getting reborn as her 20 year old self, there is still time to fix everything. Lou Yao Yao decided to live as a genuine vicious woman. After getting her hands on the loyal like-a-dog man, she would show that cheating couple what pure loving affection looked like.
