This is a world filled with interdimensional portals, monsters, and star beasts. Awakened humans form groups to fight against various monsters, protecting the peace. Jiang Xiaopi, who has transmigrated into this world, grows from a lowly child into a medical-type awakened person who frightens both teammates and opponents alike, all thanks to the considerate guidance of his beautiful elder sister. Due to his peculiar trait of causing misfortune to whoever he heals, he is nicknamed the "Toxic Healer."
