Tio Klarus/Chronology

History
Tio originally came from the Klarus dragonman tribe. As a child, Tio grew up in an era where beings of all races could coexist in peace. Unfortunately, Tio's race was betrayed by the followers of the god Ehit and began to wage war on the dragonmen after being labelled as enemies of god. Tio wished to fight after witnessing many of her people dying in battle, but her father Kharga stopped her after retreating from the battlefield with severe injuries. After seeing many of her people crucified (including her mother), Tio became consumed with rage and desired vengeance, but Kharga brought her back to her senses after reminding her that dragonmen were protecters. He explained that the true enemies were the gods of Tortus and that they must prepare for the day when they will be defeated. He ordered her to escape with the survivors unnoticed so that the world would believe that the dragonmen will have perished, while he stayed behind and would sacrifice himself. Kharga managed to buy enough time for Tio and her attendant Venri to escape.

Tio and the surviving dragonmen, including her grandfather, escaped into isolation and lived on a hidden island for centuries. During that time, Tio trained immensely everyday until she reached a point that she had surpassed even her grandfather in strength. She was approached by many young suiters during her youth, but turned them all down due to only wishing to be married to someone that could defeat her in combat, which none of them were able to achieve.

When her people sensed the arrival of humanity's heroes that were summoned from Earth, Tio volunteered to venture into the outside world to determine how powerful they were. The long journey left her tired and she slept for a whole day. That led her to become susceptible to brainwashing by Yukitoshi Shimizu. She met Hajime's party at the northern mountains of the village of Ur and attacked them due to Shimizu's influence. After her defeat at the hands of Hajime (by sticking the stake of "Pile Bunker" to Tio's rectum), she became devoted to him. She became a masochist after being beaten by Hajime and called him master as a sign of her devotion.
