Heise Qingdaofu

The seeds born of twisted desire take root deep in the heart, feeding on emotions and expanding non-stop. When all of life is sucked away, the seed receives the key to the world and the black monster is born quietly. They are called "evils".

In order to liberate the souls bound by "evils", a group of resolutely determined people, with the strength of the will from the world, become the light to illuminate the world at the cost of their own life.
