Mepple is very arrogant because of his status as a chosen warrior. Because of this, he always expects the best of everything and to be respected by others. Due to how he often criticizes or taunts Nagisa, the two of them argue a lot while he feels no regret. Due to both having a temper and stubborn personalities, they instantly deny any accusations that they are like each others.
Despite this, when he is with Mipple he is a much gentler person and loves her very much. He never demands things from her, and always hugs/cuddles with her when they can see each other. This makes him mildly jealous of Pollun due to their close past, and often wishes that he'd be less selfish. Though he is just as selfish, usually whining about being hungry, or just acting too lazy to do anything. He even has said Nagisa is very easy to manipulate.
