While he was trying to control the level of corruption on Furball, he also watched the fight. In the blink of an eye, thousands of monsters had been taken by the corruption emanated by Lucifer, and now they were being teleported to near the battlefield of angels. Yahiko, Natasha, and Fang Shi came to fight Lucifer, but they were forced to change their goals and face the monsters.
A salamander suddenly approached Yahiko. While that monster wasn't supposed to be that strong even at level max, the power of the corruption made the creature grow three times its usual size. Yahiko planned to cut its head with a single strike, but he changed his mind when the monster opened its mouth, and dark flames came out of it.
