Elizabeth, third princess of Britannia's Liones Kingdom, carries a lineage marked by a divine reincarnation cycle. She is the 107th incarnation of a goddess, bearing memories of a past life as Liz who shared a profound bond with Meliodas. This recurring identity fundamentally shapes her destiny.

Falsely accused of treason, the Seven Deadly Sins disbanded. Believing fiercely in their innocence, Princess Elizabeth set out to find them, seeking their aid to liberate Liones from the Holy Knights corrupted by the Demon Clan. Her quest successfully regrouped the Sins, leading directly to the kingdom's restored peace.

During the search for King Bartra's birthday celebration ingredients, Elizabeth remained with the group upon the arrival of Solaad, a Celestial seeking help. She journeyed alongside the Sins to the Sky Palace to confront the Six Knights of Black and the unleashed Indura. In the climactic battle, Elizabeth's abilities combined with the power of the Celestials and the Seven Deadly Sins to destroy the Indura, demonstrating her integral role in uniting forces against grave threats.

Elizabeth consistently exhibits deep compassion and a strong sense of justice. Her unwavering resolve to protect others—be it her kingdom or the Celestial race—defines her character. Her relationship with Meliodas is built on mutual trust and a connection transcending lifetimes, influencing key decisions throughout their journey.

Latent powers tied to her divine heritage manifest within Elizabeth, including healing abilities and the potential for greater capabilities awakening during critical moments. These powers contributed to the Indura's defeat in the Sky Temple, combining with her allies' strength. Her presence often serves as the group's moral anchor.
