Leg
"Grrroaarrgh!" as the lower part of his leg detached from the rest of his body, Ogai let out an excruciating cry. His humanoid voice dispersed amidst a demonic pachyderm scream, and his four arms spread outward, desperately trying to keep his balance.
Yoichi's draconic flames burned his opponent's wound, consuming the flesh bit by bit. The most resistant and challenging obstacle to overcome, Ogai's tough skin, had been destroyed: Kenji's power finally had the chance to consume the enemy's body from the inside, preventing the black mud from regenerating new wounds.
The giant boss of the Blackvault mines toppled over like a colossal stone statue in the middle of a town square. When the knee of his intact leg gave way under the weight of his massive, muscular body, he collapsed to the ground, slamming violently into the layer of black mud.
