Mathias is not a clown. He just doesn't want to be away from Alicia, his weak sister. Unfortunately, Cindy being his girlfriend was a point to make him a mockery. It was like the Beast loving the Princess. And Ryvel is the one who dislikes Mathias' closeness to the noble Cindy the most. Everything changed in the blink of an eye when the Demon Army invaded the Land of Purbha. Mathias loses Alicia, discovers that Cindy is having an affair with Ryvel, and becomes the target of the monsters. But the heavens had not destined Mathias to die. In great pain, he found a unique crystal in a cave. The crystal not only healed him miraculously but also gave him unlimited great power, provided, he had to kill every alpha of the monsters and absorb their souls. He returned as a different person to everyone's amazement, also discovering that his sister had been made into a prostitute by Ryvel. Alicia eventually died in Mathias' arms, and Mathias became enraged, becoming everyone's enemy. He killed every single one of them who had ever hurt Alicia. His pursuit of Ryvel leads him to many parts of the world until he ends up in Svarnabhumi. Getting revenge isn't as easy as it seems. Here, Mathias must face trials, temptations, and death.
