Tione Hiryute (ティオネ・ヒリュテ) is a first class adventurer and a member of the Loki Familia. She is the older twin of the Hiryute Sisters.
Tione is in love with Finn Deimne and gets angry when other women try to flirt with him. She used to use dirty language, but cleaned it up after meeting Finn. However, her language returns to normal whenever she gets angry.
Tione and Tiona were born in Telskyura and were forced to join the Kali Familia from the moment they were born. Both sisters didn't know who their parents were, but knew that they were sisters. She reached Level 2 on her fifth birthday after she unknowingly killed Seldas, a person that she had viewed as a mother and an older sister, in a daily fight to the death, resulting in her resentment of Telskyura. Soon after, both sisters became students to Argana and Bache.
The day before Tione's seventh birthday, Tiona asked Kali to let them leave the country, which she granted a couple of days later, much to their surprise. The sisters traveled across the land, temporarily joining different Familia for a year, during which both sisters reached Level 3. They arrived at Orario years later when they were 12 years old. After agreeing to join the Familia of the adventurer that defeated them, they proceeded to defeat everyone that challenged them, only to lose to Finn and Gareth when they were challenged by the Loki Familia. Upon her defeat, Tione fell in love with Finn, and desperately tried to make herself into a woman he would like.
Following a dungeon expedition they went on shortly after joining, both sisters reached Level 4.
