Flare Arlgrande Jioral

Freia, real name Freya Arlgrande Jioral, is the Technical Hero and the main heroine. She is the princess of the Jioral Kingdom and is now currently Kearuga's companion and slave.

Summary
Freya originally found Keyaru in his village and took him back to the capital to train him as a hero after identifying him as one. However, once she found out Keyaru's status as a Healer Hero, Freya started to abuse him and treat him as a slave, feeding him a drug to make him submissive.

The abusive treatment would not last however, as Keyaru has travelled back from the future and has taken countermeasures to deal with the drug she feeds him. Eventually, Keyaru escaped from his imprisonment and managed to capture Freya.

After raping and torturing her, Keyaru performed his 'Upgrade' skill on her to slightly modify her appearance and erase her memories. With this, the former princess Freya was gone.

After she woke up, Keyaru convinced her that she was his lover and slave. He told her that her name is Freia and introduces himself as Keyaruga. He then proceeds to engage in sexual intercourse, which she submissively accepts. Afterwards, she joins him as his follower and the magician hero.

Pre-Memory Loss
On the outside, Freya appears to be kind, graceful and honest woman. She is able to become very popular due to her charms and beauty. However,on the inside, Freya is a manipulative sadist, able to torture and abuse her victims without any sense of remorse. Freya is also cowardly, as she begged Keyaru for forgiveness and making up excuses on why she treated him like garbage.

Post-Memory Loss

After being brainwashed, Freia is now completely loyal to Keyaruga and is now genuinely in love with him. Freia also actively engages in sexual intercourse with him, claiming that it is rather enjoyable. She is also much more kinder than her former self, as she treats Setsuna as a friend even though her nation mistreats demi-humans.

Freia still harbours some of her former self's traits, such as her talent in manipulation. She is able to impersonate her former self flawlessly and she is also good at lying.

Etymology
Her name and fake name Frea (フレア) and Freia (フレイア) alluded to the offensive magics Flare (フレア) and Flareja (フレアジャ) from the Final Fantasy series.
