Description
Lisa Alpacas, Princess of the Ogre Kingdom, holds a position of status among her people. She possesses pink skin, long white hair, two horns, red facial and shoulder markings, a distinct tail, and a tall, slender build. Her typical attire includes a backless black top fastened to a choker, matching stockings, a grey belt, brown gloves, boots, a waist cloak, and elbow bands.

Her personality is defined by a belief in ogre superiority and a refusal to marry anyone weaker than herself. Though initially preferring an ogre partner, she pursues Peter Grill after he is named the "Strongest Man in the World," seeking powerful offspring and viewing him solely as a genetic asset. She employs cunning and manipulation, using blackmail and threats—such as exposing his infidelity to fiancée Luvelia Sanctos—to coerce Peter into sexual encounters. She demonstrates hypocrisy by planning to sever all ties with Peter after achieving pregnancy while simultaneously proposing he abandon his human life to become the ogre king.

Her pursuit begins when she and her younger sister Mimi witness Peter's victory at the Grand Fighting Tournament. They confront him immediately, declaring their intent to bear his children. After initial rejections, they use seduction and physical coercion to succeed. At Peter’s engagement celebration, they announce their continued pursuit, leveraging the threat of exposure.

Lisa actively conflicts with other women seeking Peter’s lineage, notably defeating the elf Vegan Eldriel in a physical fight. She participates in group schemes to measure Peter’s arousal, reflecting her competitive drive. Her tactics include manipulating Peter’s battles, such as sabotaging his plan to lose a duel against Antonio Spartacos by threatening to reveal his secrets.

Her relationship with Peter is characterized by persistent coercion for the purpose of producing strong ogre heirs. She competes with other harem members like Vegan and Piglette Pancetta, often judging rivals based on physical attributes like bust size. Her dynamic with Mimi is collaborative, with both sisters working together towards their shared goals.

In later events, she remains a persistent figure in Peter’s life, continuing her efforts to conceive his child while navigating threats from other species. Her role expands to include interdimensional travel during the Goblin Arc, where she assists in resolving conflicts in another world before returning. She is recognized as the leader of Peter’s unwanted harem across media.
