Lupa

Lupa is a homemaker and bookkeeper for Purio, dressed in a long black dress and notable for her large nose and large black afro.

Although Purio is primarily her partner in the Mamodo fight, Lupa also sees him as a replacement for her son, who died of a heart condition not too long before the two met each other by his gravesite. Seeing this Mamodo boy as a replacement for her own son, Lupa does whatever she needs to in order to love and protect him from both the evils of the tournament and from his own stupidity.

Lupa spoils Purio to make sure he gets what he wants (even if it means using spells to help him in this manner) and sometimes she uses his powers for evil and selfish reasons like breaking into houses, responding to Purio's demand to destroy an amusement park ride without thinking about the people on the ride, torturing Gash and Kiyomaro with Purio's then-new powers and firing enough acid on the mamodo Rein to fatally burn a human being. She is also is willing to go in the line of danger to protect him from enemies. However there are many times where she is found to be as cowardly as her Mamodo, using his spells as a means to escape and survive for another day.
