Paul Moriyama
Momoka’s butler and sometime-bodyguard. He is fiercely protective of his mistress, and willing to do anything for Momoka, from helping with her efforts to win over Fuyuki to risking his life for hers. As a war veteran, he has a rather strong feeling of camaraderie with the Keronian invaders (especially Giroro), whom he sees as fellow soldiers. Paul was defeated by Momoka’s father, Nishizawa Baio, many years ago in a battle (Pōru-Reppa was a parody of Ken Masters’ Shōryū Reppa from the Street Fighter (video game) arcade game), becoming one of the most favored Nishizawa butlers. He is sometimes accompanied by other soldiers, minor recurring characters who are seen protecting Momoka or tracking things in their headquarters. Source - Wikipedia
