Like everyone else on the tour to Nanaki Village she is trying to protect her identity and start a new life with everyone else in the village.
In episode 6 it is revealed that Love-pons mother was in an abusive relationship with a Monk who was often drunk and would beat Love-pon and her mother, who he also gives money in return for sexual services to pay for the debt Love-pons father left on them when he disappeared.
Love-pon shouts "execute" a lot, this is because of the abuse she received when she was young, since she believed that the Monk deserved to die for what he did to her and her mother.
