Under the neon rain of the modern city, ordinary college student Sen Ran became symbiotic with the ancient demon Asha due to an accident. From then on, he was involved in the desperate battle between demon hunters and demons: the whispers of demons in his body kept eating away at the soul, his crush Miaomiao actually had forbidden blood, and Dongyang, the seemingly righteous leader of the demon hunting group, was brewing a shocking conspiracy to resurrect the Lord of the Abyss.
Sen Ran was originally a kind-hearted young man, but he was forced to make a counterattack from a weak student to become the strongest demon hunter in the world. He longs for the coexistence of humans and demons, but faces the ultimate choice in the intertwining of love and hate: Should he sacrifice his beloved, or let the city sink into the eternal abyss?
What is love, what is kindness
