Now that Yuki had his palm on the robber's head, Yuki dragged him across the floor as he continuously slammed his head on the ground. With every second that passed, Yuki grew in anger as he tried to imagine what would've happened to the toddler. In doing this, Yuki had grown so angry that he let his flames lose control and burn through the mask that the robber was wearing and reach into the robber's skin. He had caused deep burns on his face, so much so that the robber began to cry, however Yuki still looked at him with an evil glare. Only once the robber in the middle shot Yuki in the head with a pistol did Yuki snapback.
The bullet which was fired at him obviously didn't do much damage as Yuki was at too high of a level to be harmed by regular human weapons. The bullet just hit Yuki's head and bounced off like a rubber ball. This had caused the one who shot Yuki to be confused.
"Did I miss my shot? Ya, that's probably it," the robber tried to reassure himself.
