Mepple is the chosen protector of the Princess of Hope. Because of this he and Mipple have a loveydovey relationship. He tends to be a little more agitating constantly making fun of Nagisa as they get into arguments. He is also mildly jealous of Porun and wishes Porun would act less selfish at times. However Mepple is just as selfish constantly eating or whining about being hungry and noting to himself that Nagisa is easy to manipulate. He resides with Nagisa and ends his sentences with mepo. Both Mipple and Mepple can only stay in their Garden of Light forms for a short time before growing tired so they generally take energysaving forms resembling cellphones.
