History
Tiana was a princess of a country known as Termine in the world of Ixphoria who joined a party in order to defeat the Demon Lord and was very close with its leader; Seiya Ryuuguuin.

During the fight against the demon lord, it was revealed that she carried Seiya's unborn child and she was killed alongside the baby.

Due to Ariadoa's guilt, Tiana was then reincarnated as the goddess Ristarte 100 years before the start of the series. She trained as a goddess to save worlds fated for destruction until she tasked with saving the S-rank world of Gaeabrande.
