Nyx & Funikura

Nyx is a peasant girl born to a laborer in the service of Count Vance. When Nyx stumbled upon Funikura, an evil sentient staff, she was granted impressive magical powers. She then entered the Queen's Blade tournament to prove her worth to those who have looked down on her through her whole life, as well as seek revenge against Elina, her former tormentor.

Funikura is Nyx's weapon, and is a living staff. She stumbled upon it, which it then began to control her

History
Nyx is a wandering magician that manipulates flames at will. She has a strong sense of justice, but she's dangerous because she can't really control her skills and emotions. It's not unusual for her to want to only burn down the house of some evildoers, but ending up burning the whole village to ashes.

Daughter of a low caste worker from the Count Vance's castle, from her birth she was raised with constant abuse from the people around her. As a result, she became shy and talentless, while deeply hating the irrationality and the evilness of the world.

Unexpectedly, one day she got a mysterious wand that changed her life. With the infinite power received from her wand, the forbidden treasure Funikura, Nyx decided to hunt down the evil people. So as to not be underestimated by the evildoers, she wore an exuberant dress and learned to use rude words she wasn't used to.

The treasure Funikura has a will of its own and it's an evil being that desires to control its host with violence and "sweet honey". When Nyx fails at a spell, or when Funikura wants her to improve, or for no reason whatsoever, Funikura punishes Nyx without mercy. Ultimately, Nyx is a simple plebeian with a weak mind. Aware of her mediocrity before Funikura and fearing to lose the immense power she now has in her hands, Nyx keeps on fighting.

Until the day when she's crowned queen and she can look down triumphantly on all those who despised her.
