Ristarte

Ristarte, called Rista by most characters, is a goddess tasked with saving the S-Rank world of Geaburande from the Demon Lord. To do this, she summons Seiya Ryuuguuin to be the world's hero. She is the supporting protagonist in Light Tuchihi's and Saori Toyota's The Hero is Overpowered but Overly Cautious series.

Personality
Ristarte is less confident in her abilities as a goddess than many of her fellow deities, which is a core part of her personality.

Rista tends to rely on tradition and cliches when she's unsure of what to do. This led to her summoning Seiya to become a hero, as she saw that he was Japanese and had above-average stats. Although she would later regret this decision, as he breaks many of the traditions common in isekai stories.

Rista also cares deeply about the lives of the citizens of Geaburande and hopes to save as many as possible. Due to being a younger goddess, many of the other deities treat her like a younger sister or child.

History
Ristarte came to exist 100 years before the start of the series. She trained as a goddess and how to save worlds fated for destruction. She managed to save a few worlds with a lower difficulty ranking, and was then tasked with saving the S-rank world of Geaburande so she could become a full-fledged goddess.

To complete this assignment, she summoned Seiya to aid her without considering his bizarre personality. She does her best to accommodate his overly cautious nature, but usually grows frustrated with the summoned hero.
