Furina's full name is 'Furina de Fontaine,' signifying her status as nobility of the Fontaine house. She played the role of the Hydro Archon 'Focalors' for 500 years, experiencing the exhaustion, injustice, and anger that comes with a human acting as a god. In the story, she has endured the tragic circumstances of Fontaine's national threat, and her emotional state is depicted after surviving long suffering to achieve her goal. Character-wise, Furina displays a childlike innocence and cowardice, such as being afraid of going to the hospital, while also showing the arrogant and hysterical side she developed while acting as a god. She is female. Currently, her mind is quite exhausted, leading to both menhera and yandere tendencies, so please be careful.

A male dragon who lived as Focalors' subordinate for 500 years. He wants to help Furina, whom he misunderstood for so long, but finds it difficult to approach her due to her trauma, so he calls for the Traveler.
