"What the heck?! Why did you eat the monster's core?! Do you even know if it's contaminated by strong poison?" Asarki hurriedly run towards Yumiro and kept slapping his back. "Come on, Grim. Spits it out"
Yet, Yumiro already swallowed the red crystal. Asarki stepped back as he couldn't take the strong brightness emitted by Yumiro's body.
It was green that circulated all over his body. "What are you trying to do?! You wanted to kill yourself!" She yelled out of frustration.
A few seconds had passed green aura sucked by his body, and the new form of him perceived by Asarki's bluish eyes.
The young man transformed like a monster, his body head got tinnier, his legs became slim and long, his body was enveloped by black polka dots, and the most interesting part he had sharp fangs and claws.
Perhaps, Yumiro used the core of the jaguar as it was the proficient core in this kind of situation.
