OVA
Description
Lala Satalin Deviluke, first princess of Deviluke and daughter of King Gid Lucione Deviluke and Queen Sephie Michaela Deviluke, fled her homeworld to escape political marriage pressures as heir to the throne. Her departure did not diminish her close bond with younger twin sisters Nana Astar Deviluke and Momo Belia Deviluke. Demonstrating exceptional childhood intellect, she created the robotic companion Peke, functioning as both friend and shapeshifting clothing generator. Her early years included friendship with the Memorze royal Run/Ren, showing preference for Run.

Physically, Lala possesses pink hair, green eyes, and a distinctive Devilukean tail ending in a heart-shaped tip. Her measurements are consistently noted as B89-W57-H87. Peke typically resides as a hair accessory that transforms into her outfits, though she later adopts independent Earth clothing. Her Devilukean physiology grants superhuman strength, speed, an enhanced metabolism preventing weight gain, and energy projection via her tail. This tail exhibits hypersensitivity, particularly in Devilukean females. Her abilities include teleportation and telekinesis; excessive power usage once regressed her to a childlike form after deflecting a major attack from Golden Darkness, requiring weeks for gradual recovery.

Lala radiates bubbly enthusiasm mixed with scatterbrained tendencies, often causing comedic or dangerous misunderstandings due to naivety about Earth customs. Despite a seemingly childish demeanor, she possesses genius-level intellect focused on inventions, though her gadgets frequently malfunction. Minimal modesty from her royal upbringing leads to casual nudity, yet she demonstrates embarrassment in overtly sexual situations. Compassion defines her core, leading her to voluntarily reduce physical contact with Rito Yuuki upon learning of Haruna Sairenji's feelings, encouraging their relationship while maintaining her own engagement to him. Emotional maturity surfaces during conflicts, such as intervening when her sisters pressured Rito, recognizing his distress. She later advocates polygamous marriage solutions under Devilukean law.

Her narrative begins with an accidental teleportation into Rito Yuuki's bath. His misinterpreted rejection of forced marriage was perceived as romantic acceptance, sparking her genuine affection. She moved in with Rito, attending Sainan High School while contending with persistent suitors and assassins like Golden Darkness. As the series progresses, she supports Rito's relationship with Haruna while navigating her own feelings, culminating in Rito confessing simultaneous love for both. Lala enthusiastically proposes a polygamous resolution based on Devilukean royal marriage customs. In subsequent storylines, her role shifts focus to sister Momo's "Harem Plan," which Lala supports while occasionally creating devices to advance Rito's relationships. She experiments with more mature expressions of affection under Momo's guidance, including attempted romantic advances toward Rito.
