Leopardon Papipurio

Purio is a bratty, arrogant eight-year old Mamodo child. Of the Mamodo taking part in the Battle to Determine King of Mamodo World, his appearance is the most royal of all children: dressed in a princely pinstripe outfit of blue and white with a crown on top of his combed blond hair. Purio admits that he is a weakling and that his spells may not be strong enough on their own to win the king tournament. Thus, he decides to be a front for various other Mamodo he teams up with, speaking on their behalf and trying to use his egotistical, me-first personality to show a strong front compared to his weakness.

Purio easily becomes jealous at things other people have and usually tries to take them for himself while taking advantage of the motherly nature of his bookkeeper to do so. (even to the extent of growing a beard similar to the bookkeeper of one of his former allies) However, he does care about his bookkeeper Lupa and will do anything to help her, even with her smothering, caring love.
