Key: They.Call.Me.Taco
Character: Jung
Skill(or transformation): Sharingan

Reasoning:  Jung is the offspring of the Demonic Forces Soldier Mori and the Maki-Infused Nun, Jean. As the child of the duo, Jung carried over some but not all of their heritage. Lacking the demonic might that was bestowed on his father and the energies that circulate inside his mother, he however did inherit something in specific.

The Sharingan.

The curse of hatred that bestowed his Dad his powers had also been passed onto his son. Jung has already been informed of its existence by Mori and was given rules in regards to it. So now it was just time.. Time before it also awakened within the young boy.

To carry on the legacy of his father.
