Personality
Stella initially appears to be feisty, hot-blooded, and quick to anger possibly due to her sheltered upbringing, as she was shown arguing with Ikki, after he accidentally walked in on her dressing and then stripping to make things even, even going as far as to want him to kill himself just to make up for it.

However, later on she is shown to be anything but bitter, and is even willing to admit her mistakes and be friendly with others. Despite this, she is still reckless and impulsive, and exhibits frequent bouts of jealousy when it comes to Ikki, especially when it comes to women as she wants to be the one who makes Ikki the happiest.

Ikki, despite being a better swordsman, had noted that there wasn't any flaws in Stella movements and not much he can teach her. Immense Magic Power: Stella possesses an immense amount of magic power that she was unable to control as a child. After years of hard training, Stella finally mastered her power and is now able to use powerful attacks continuously without showing signs of fatigue. According to Stella, her magic power is 30 times that of a normal Blazer.
 * Tsunoou/Harmonic Bullet: A combination attack of Stella and Ikki. It's an attack where Ikki uses his first secret sword technique, Saigeki, while Stella strikes with a powerful slash. The attack is called Tsunoou by Ikki, and Harmonic Bullet by Stella.

Immense Durability: Stella has shown being extremely durable. She took a hit from Rinna's King's Charge, without a scratch.

Immense Metabolism: Though not necessarily a power, It has been shown that Stella's fire magic literally burns calories for her to use causing her to have a large appetite and may be the cause of her slim figure. When Ayane comments on the amount of food she eats. Stella stated that she needs to eat a lot or her body gets sluggish, and Yui has told her one of her biggest weaknesses is that she wastes calories that fuels her magic.

Dragon Breath: Stella's Noble Art, mainly comprising of the ability to summon and control flames. This particular kind of flame carries some of the common properties of natural fire like radiant heat and light, but does not immediately burn anything it touches. Stella uses Dragon Breath in both offense and defense, creating an invisible barrier that blocks incoming attacks, as well as extending the flames to attack any nearby foes. In actuality, Dragon Breath is an ability that allows Stella to gain the abilities of a dragon.
