""Pierce the blue sky, blaze of purgatory.""

- Stella Vermillion

Stella Vermillion is the primary female protagonist of Rakudai Kishi no Eiyuutan. She is an A-Rank Blazer and second imperial princess from the Vermillion Empire known as the Crimson Princess. Stella was born with 30 times the magic power of a normal Blazer viewed as a prodigy appearing once a decade, however, she lacked control her abilities and so it required her to work harder than others would expect in order to attained proper control over them.

In order to aim for greater heights, Stella decided to study abroad in Japan as a first-year student at Hagun Academy, in which she met her roommate Ikki Kurogane who she didn't realize that he was her roommate and thought he was a pervert. After their match to decide who would be the others' slave, Stella found herself to be the loser yet she grew to respect and love Ikki despite being the Worst One.

Appearance
"Beautiful. Ikki couldn't think of another word to describe those features. Her beauty was like a painting of a goddess, evoking a solemnity that left no room for wicked lust. She simply captured the eye."

- Ikki Kurogane after meeting Stella for the first time Stella is a beautiful young woman of average height with a beautiful face, white skin, and ruby eyes. She has long crimson hair tied into twin tails using yellow ribbons. She has a bewitching body, with both large breasts and a voluptuous figure. Ikki likens her appearance to that of a painting of a goddess, and that her beauty left no room for wicked lust.

There have been several situations where Stella has worn different clothing, the most well-known and constant being the female school uniform for Hagun Academy.

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.

Stella also dislikes being called a prodigy or genius and holds contempt for anyone who views her natural abilities as being her lone source of strength, as she wants to prove that she is more than a just prodigy, and she desires to show her capabilities with a sword, as well.

Stella has often shown to have a perverted side to her when it comes to Ikki. After the mock battle, she straddles him while he is asleep, and she also wanted to wash his back when he was bathing, even rubbing his back with her breasts. After their talk in the hospital, she complains to herself that Ikki hasn't done anything after admitting to herself that they have become "lovers". Ayase even noted that during their talk at the pool, Stella didn't say she was against doing "it" with Ikki.

When she and Ikki were resting in the cabin at the Okutama mountains, she realized that she thought about such things more than him, who understood that he needed the approval of her father first and would restrain himself until then. It is also shown that she tends to have erotic dreams or fantasies about Ikki. When Ikki finally decided to make love to her, Stella quickly accepted and allowed Ikki to do whatever he desired with her and later stated that she didn't want the pain to disappear quickly as it was proof Ikki loved her.

Abilities
Desperado: During her battle with Fu Xiaoli, Stella reached her Awakening and became a Desperado, a being that has broken the chains of fate. As a Desperado, she can increase her mana capacity, with her techniques receiving a boost of power.
 * Excessive Awakening: In her fight with Or-Gaule, Stella entered this rare second form, having seen Ikki's head crushed. Due to crossing the lines between humans and demons, Stella attained enormous power at the cost of losing her humanity. Her skin becomes black with shining scales on some places, two horns are grown on her head, wings sprouted out from her back and a long tail has extended from her tailbone area.

Immense Magic Power: Stella possesses an immense amount of magic power that she was unable to control as a child, which was 30 times the amount of a normal Blazer.

Dragon Manipulation: In her training with Nene, before the Seven Stars Sword Art Festival Finals, Stella realized that her Fire Manipulation was just a part of her true power, which was the concept of a "Dragon" thus granting her all the abilities of the apex predator heard of within various mythologies. This was shown as she was able to manifest the phantom image of a dragon letting her throw balled up paper with enough force to break a metal pipe and dug into the concrete wall behind it.

Immense Strength: Through her enormous magical powers, Stella has proven to be capable of augmenting her physical strength to superhuman levels, to the point of her being able to create craters using her slashes and was capable of overpowering Ikazuchi's full powered ten-ton attack in one clash using his Crescendo Axe. After Stella trained with Nene and realized her true power, she was capable of sending opponents flying with one punch.

Immense Durability: Stella has shown being extremely durable. In her training with Nene, she had to endure all her powerful attacks for the entire time, and it resulted in her being durable enough to endure the King's Charge of Sphinx and the Sweeping Centipede of Yui Tatara, then stood up as if nothing happened.

Immense Speed: After her training with Nene, Stella's speed increased considerably and was able to maneuver and dodge both Yui's and Rinna's attacks without many difficulties and keep up with Ouma and Ikki's speed.

Immense Metabolism: A unique trait of Stella's fire magic is that it literally burns the calories in her body causing her to have a larger appetite compared to others, even causing her to act sluggish if she doesn't eat a large meal, which could be the cause of her slim figure. Her irregular metabolism has proved to be a big weakness as shown in her fight against Ikki as pointed out by both Kurono and Yui, as it turned through more magic and calories than required. After Stella received instruction from Yui, she had become able to control her heartbeat and as such her metabolism and reduce the consumption of her Dragon Spirit.

Master Swordsmanship: Stella has shown to be proficient in swordsmanship, using her Imperial Sword Style as her main swordsmanship. Ikki, despite being a better swordsman, had noted that there weren't any flaws in Stella movements and not much he can teach her.
 * Tsunoou/Harmonic Bullet: A unison attack between Ikki and Stella, in which he jumps forward and attacks using Saigeki, then Stella sends him forward using a powerful swing sending him forward with much greater strength than normal. It was named Tsunoou by Ikki and Harmonic Bullet by Stella.
 * Trackless Step (抜き足, Nukiashi): At some point, Stella learned the Trackless Step, as shown when it was able to let her instantly get behind Akaza, without him noticing.

Magic Control: Despite what other Blazers and others failed to believe, Stella has to work harder than others in order to control her enormous magic and became able to use several powerful attacks without showing the even slightest sign of fatigue causing Ikki to compare to her an ultra-high mobility heavy tank with infinite fuel.

Device
Lævateinn : Stella's Device, it takes on the form of a golden broadsword with red markings on the hilt and it can be clad in her Dragon Breath. In her fight with Fu Xiaoli, Lævateinn changed into a larger golden blade, higher than Stella, and thicker than a man's arm.
 * Dragon Breath (妃竜の息吹, Hiryuu no Sokusui): Stella's Noble Art, mainly comprising of the ability to summon and control flames. These flames carry some of the common properties of natural fire like radiant heat and light but they don't immediately burn anything it touches. Stella uses Dragon Breath in offense and defense, creating an invisible barrier, which blocks incoming attacks, as well as extending the flames to attack nearby foes. She soon realized her true abilities as a Blazer, which was the concept of a "Dragon".
 *  : Stella's ultimate technique, Lævateinn transforms into a sword made from both the heat and light at that had no physical form, and can it reach a target more than a hundred meters away. Katharterio Salamandra has soon grown powerful enough to split an entire mountain in half.
 * Empress Dress : Stella creates a dress made of flames that acts as armor. The weakness of the technique is that as it surrounds Stella with flames, it covers her sight, which in turn hinders the techniques close-range effectiveness.
 * Dragon Fang : Activated by igniting Lævateinn in flames, Stella creates a three meter long serpentine Dragon clad in flames that can target its opponent.
 * Satan Fang: This is an enhanced version of the original Dragon Fang, which shoots seven flaming Dragons instead of just one.
 * Broken Arrow: A technique, which shoots out multiple fireballs at the opponent.
 * Flame Veil  (熱霞幕, Heat Haze Curtain): A technique, that temporarily hides the user by refracting light from the heat. It can also create mirages of the user.
 * Bahamut Howl (暴龍咆吼, Bouryuu no Houkou): Stella's ability that allows her to engulf an entire area in nothing but her own flames, which would burn for twenty seconds straight. It is stated that she could engulf an entire town using this ability.
 * Dragon Stomp: Stella smashes her foot into the ground, releasing flames.
 * Dragon Nest  (龍妃巢穴, lit. Dragon Princess Nest): Stella stabs the ground with Lævateinn, which causes the ground to slowly melt away.
 * Dragon Wing: Stella uses flames to manifest herself wings, which allow her to fly through the air.
 * Dragon Spirit (龍神憑依, Dragon Spirit Possession): Stella's most powerful technique, which she learned in her training with Nene and grants her the abilities of a dragon. Dragon Spirit enhances her strength a dozen times over similar to that of Ittou Shura, letting her overpower Ouma in their fight and even keep up with Ikki in the finals, Stella is also granted high-speed healing that is almost instantaneous. A major drawback of it is that it burns through her magic and calories, which decreases its power over time and to where she cannot maintain it. After Stella received instruction from Yui in controlling her heartbeat and metabolism, letting her maintain her Dragon Spirit for much longer than before.
