Mediocre is a common characteristic of the majority. But when someone outstanding appears beside you, your life will change because of him. That’s the principle of ‘who you mix around with is a reflection of yourself.’ The doctor in charge of the Three Flavour Hall will change everything. You can raise a campus belle, a CEO beauty…

After dying miserably, Chaos suddenly finds himself reborn in the body of a chimera between a Vampire and a Dragon created by an insane Elder Lich who claims to be his father.

Thrown into a an universe filled with darkness, monsters, dungeons, and gods, he finds himself born as the calamity of the entire galaxy, the primordial evil, an entity that shouldn’t exist!

Packed with a cold-headed mind, a calm demeanor, and the power of both Vampires and Dragons developing within his chimeric body, Chaos will awaken his Chaos Magic, and gain Skills from the monsters that he eats, bringing forth the end of all those that dare come to take his life!

This is the tale of the Devourer of Worlds, the Living Calamity, the Primordial Evil, Chaos!

But was he all of this? Or was Chaos misunderstood?

Watch as Chaos discovers the truth about his origins, and finds a purpose in his new life, and the fate that awaits him!

The protagonist, Winnie (文尼), confesses his love to his childhood friend—the princess he’s been secretly in love with for years—but is brutally rejected in public. His heart shatters, he’s humiliated and ridiculed, and he collapses unconscious. When he wakes up, he vaguely remembers his past life’s memories and realizes he has transmigrated into the world of an otome game he played before. At first, he’s thrilled, thinking, “Nice! I must have been reincarnated as a villainous side character who disrupts the protagonist’s romance, right?” But then… surprise! He’s not just the villain—he’s the “Saintess”!

There is a very strange restaurant in the City of Sin.

Elves and dwarves must share a table, orcs are strangely well behaved, dragons are only welcomed on the small square in front of the restaurant, and the demons must bring their own stool.

This strange restaurant with their strange rules continuous to attract a long line of customers.

“This place serves the best food! The chef of this restaurant is a genius!” Some of the guests in the restaurant left glowing reviews. But these guests have a word of warning for other guests, “No matter what you do, never, never attempt to kidnap the boss or try to ‘eat and run’. You will die.”

A cute little girl stood near the door, and demanded in her tiny voice, “You have eaten the food, now pay up, or I will beat you to death.” The five-meter tall dragon suddenly felt a chill running up its spine.
