From childhood to adulthood, Zhuang Ziang has always been the so-called child of other people's families. He was a three-good student every year and ranked first in exams. However, because his parents divorced and his father remarried, he became unloved by his parents.

At the age of eighteen, Zhuang Ziang was diagnosed with a terminal illness and was given only three months to live.

In the last three months, Zhuang Ziang decided to release his inner rebelliousness and wildness and be his true self.

When he climbed over the wall to skip school, he met a girl named Su Yudie. In the last journey of his life, a beam of light shone in.

The villainous young master Dark Demon finally recalled the memories of his previous life at the sorting ceremony of the Dueling Academy. He was reborn in a very strange Galgame world.

And he was the ultimate villain in the game, the Demon God of Seven Original Sins!

Superbia、Invidia、Ira、Accidia、Avaritia、Gula、Luxuria！

Once any one of these seven indicators broke through the critical value, he would irreversibly transform into the Demon God!

In the era of Saint Marian, where the demons had been completely destroyed and the demon king had fallen into eternal sleep, no heresy was allowed to survive!
