Perseverance

Lusica placed the tired Peter on the palace floor, and the boy was pale. He was not a vampire, so his regeneration was not the same, even though it was still enhanced beyond normal. As the boy closed his eyes, Ark looked at him with worry.

"I guess not even a shapeshifter can handle amputation," sighed the Knight of Courage with a worried expression. Lusica nodded as he looked at the boy's legs, which were still glowing and healing.

It seems this was one of his shapeshifting abilities, even without the enhancement of the vampire. Peter told them that he would have to use other human parts to recreate his body when this happens.

'As if he is a self-created homunculus,' thought Lusica as he remembered another fact about this young boy, and it was the fact that he never grew older. His ability trapped him in this body forever, but he never wanted to assume a different one.
