Loveriel is a high-ranking angel from Heaven who maintains a childlike appearance and occasionally immature behavior despite her 10,009 years. She remains considered a beginner within the angelic hierarchy. Her core duty involves managing the Heaven-Hell conflict. She first intervenes to rescue Rika Manabe from the demon Asmodeus. Injured in battle, she recruits humans as Devil Angels, granting transformation halos and instructing them to gather Amore—vital energy sourced from sexual activity—to fuel their powers.

Following the events of the third game, she establishes a school for Devil Angels, transitioning from direct combat to organizational leadership. This institution appears in later installments like *Makai Tenshi Djibril 4* and the cyberspace-themed sixth game, where she relocates the campus to a digital realm. Her tactics include assigning trainees such as Momo Sakura, Aoi Ayonokouji, and Yuzuha Hoshikawa while continuing to counter interdimensional threats.

Her personality merges ancient wisdom with youthful traits: she carries instructional materials to explain complex concepts yet exhibits behaviors like demanding to be carried or attempting to deceive Naoto Jinno into compromising situations. Though no longer engaging in frontline battles after the initial games, she maintains constant surveillance on allies and adversaries, often observing key characters covertly.

Loveriel is the sole character appearing consistently throughout all main entries and spin-offs. Her adaptability surfaces in non-canonical scenarios like *Sengoku Tenshi Djibril*, navigating war-torn historical Japan, and *Dennou Tenshi Djibril*, integrating celestial operations into cyberspace. Her longevity and recurring presence cement her foundational role in the conflict's overarching narrative.
