Papa is Noelle's father within the unconventional family moving into the protagonist's home. His large, imposing frame evokes a Frankenstein monster, contrasting sharply with his wife's humanoid appearance. He consistently displays a calm and gentle demeanor, often addressing the human protagonist as "son-in-law," signaling his acceptance of their relationship.

Despite his monstrous look, he possesses a fundamentally kind and patient personality, acting as a stabilizing force within the frequently chaotic household. His role centers on supporting family members, particularly encouraging Noelle's endeavors, while rarely taking center stage in conflicts or the main plot. The character maintains this gentle giant archetype consistently, with no significant personal evolution or detailed background explored. His interactions primarily reinforce familial bonds rather than driving major story developments.
