Toxic-a-Holic

The story takes place in a world where a new, toxic organism known as "void" has appeared. The only ones who can fight against the void are the "toxients," known as "poisonous men," who possess poison in their bodies. Today, they set out on a mission to eradicate the voids, for the sake of peace for humanity. This is a battle action fantasy in which the poisonous men fight poison with poison.
