Carissa (キャーリサ Kyārisa?) is the the second princess of the British Royal Family and the second eldest of Queen Elizard's daughters. She launches a rebellion and overthrows her mother but faces opposition against her younger sister and her allies. The fight between her forces and her allies, the Knights of England, against Villian's forces and her allies, Necessarius, sparks the English Civil War. During the civil war, it is revealed that she carries the sword Curtana Original, which grants to the wielder the overwhelming power of the Archangel Michael.
Of the three princesses, she possesses the aspect of "military affairs."
A woman in her upper 20's with blonde hair. She wears a red dress composed of bright red leather which gives off a suggestion of bondage related. The skirt appeared to be supported by a wire framework and is able to contract or expanded to an unnaturally large size like an umbrella. Kamijou Touma remarked that she was very gaudy looking compared to her sisters. 
From her first introduction, she doesn't interact well with the other members of her family and looks down upon her younger sister, Villian, even openly insults her. Once she begins her coup d’etat, Carissa assumes a more tyrannical nature and uncaring beliefs even to her own allies. Only until did Riméa finished her investigation and broadcasted Carrisa's true beliefs revealed more about her intentions and ideals. When Carissa had come to a conclusion that England would lose all it's value and even its people would be looked down upon by other EU nations, if the country continued on its current course. She decided that the most effective means of maintain England's honor and peace would be through military force, with Curtana Original she would rise as historical tyrant only to fall later but not before sealing all the Curtanas and any possible means of reviving them.

In the Battle of the Dover Strait, she commands the military forces defending against the attack by France , and as the Battle continues she becomes engaged in a duel with the leader of the enemy force, the Maiden of Versailles who has the artifact Durandal. Carissa by then used her secret weapon: a shard of the Curtana Second that was chipped off when Elizard used it to duel with Carissa during the UK civil war, and can grant the wielder from the UK Royal family the power to turn it into the best weapon to defend the wielder against an attack. Against the Durandal the shard produced a sword of light with the shard as the hilt, with the narrative description sounding close to that of a "lightsaber." Carissa mentions the power of the shard is weaker than she thought it would be, even in the hands of Royalty.Later when the manifestation of Archangel Gabriel and its devastation of both Academy City and Russian forces ends the Battle of Dover Strait inconclusively. Carissa and the Maiden of Versailles turn their attention to the new foe, coming to the aid of the beleaguered Academy City and Russian forces. Despite the effectiveness of both Carissa and the Maiden's weapons against the archangel's wings, they prove to be unable to harm the angel itself. Gabriel unleashes a fierce counter-attack, nearly killing Carissa if not for the timely intervention of the Maiden. It proceeds to shower the battlefield with thousands of icicles, leaving no openings for either Carissa or the Maiden of Versailles to capitalize on. Gabriel then turns its attention to the forces of Academy City and Russia—Carissa is barely able to intercept the archangel's attack, wounding her heavily and shattering her weapon. As Gabriel attacks again, Carissa reveals that she possesses more than one shard of the Curtana Second, now wielding two shards of the sword in her hands with ten more tied to her belt. Carissa and the Maiden, despite their wounds, help cover the retreat of the Academy City and Russian forces, who are in turn assisted by English and French troops. Carissa declares that they will hold until the troops reach safety. Finally, she procures a communication device from in between her breasts (to which the Maiden of Versailles is quick to criticize) and orders multiple surface-to-air missile strikes on the newly-emerged Star of Bethlehem, which is enough to force Archangel Gabriel into a retreat so that it can intercept the missiles. Carissa taunts the archangel as it leaves, but thinks to herself that the angel's power is beyond any mortal reckoning and questions how it can be possibly defeated by mere humans.

Magic God Othinus ArcEdit
- Main article: Magic God Othinus Arc
She is first seen with William Orwell and the Knight Leader after being temporarily released from the Tower of London for the emergency situation involving GREMLIN. As they prepared to leave to attack Sargasso from a naval port on the northernmost edge of Scotland, they had a brief discussion as to the readiness of the group before setting out in one of their Mobile Fortresses (the Queen Mermaid and the Hotel Ariel) for the alliance's operation. The Knight leader then got the conformation to leave and begin the assault.
On route she receives word that America and Russia will be a little delayed, and though the other two can enter as the second wave of attack, they determined that they will take all glory for themselves. William Orwell asks when Touma will get here, to which Carissa states that he should arrive by the second wave, and notes that due to Academy City's Supersonic Passenger Plane he may arrive before the American and Russian forces. As the island became visible, it is bombed by several Grape Jelly bombs and the Mont Blanc bombs. As the attack takes place, William notes on how Carissa's methods never change, and warn her that due to the incident she caused in England, the British Halloween, GREMLIN may had analyzed her methods. Carissa replies that if one removes all the waste and search for the optimal usage of one's weapons, everyone will ultimately arrive at the same place. She states that a military run by a nation needs an attack method that is impossible to avoid even if one know it is coming. As the begin to land on the island, Carissa isn't optimistic enough to think that the bombing was enough to kill all the members of GREMLIN, but believed that since they still have the physical body of a human, then they can be killed.
Landing on the island, they are informed that there is no need for gas masks for there were no toxic substances detected after the bombing. Thus, they and the British forces begin their search for GREMLIN. Then, they here a voice up on a wrecked tanker in the island welcoming them and introducing himself as Loki. He comments that "Lady Othinus" gave him the task of protecting the Sargasso of the North Sea with his life. His explanation is cut short however, after he is shot through the throat with an arrow fired via the Robin Hood spell. Loki then fell from the tip of the tanker he was standing on and slammed to the ground. Carissa then ordered all of her men to continue moving forward. He then suddenly rises, explaining that he is just an illusion and the real Loki is nowhere near the area. He further explains that he was suspicious of his teammates and worried about a spy, so he created an artificial sky over the true Sargasso and altered Marian Slingeneyer's notes. Reports from the landed forces state that the teams have found no trace of the magic god or the production of the lance in the island: it is completely empty. Carrisa and the others then realize they had indeed been led to a false Sargasso on the other side of the world. The illusion bids them farewell and disappears, just as the place is bombed.
VS The WorldEdit
Surviving the explosion in Sargasso, Princess Carissa, Knight Leader, and William Orwell are mobilized on the Hotel Ariel to go to Denmark following the sudden changing of sides of Kamijou Touma with Magic God Othinus. They are later joined by Kanzaki Kaori. They later knock Touma after his fight with Vasilisa and Sasha Kreutzev, taking him into the mobile fortress. They later prepare to use the Curtana's shard to attack Othinus. As Touma comes to, William tells him not to get up, adding that they don't particularly care about him and that it would be best for him if he simply watched as they bring the situation to an end. Carissa also comments on Touma waking up, saying that letting him freeze on the deck would have been decent punishment for causing so much trouble around the world. He also hears Kaori responding to the Knight Leader's query about bringing him aboard by saying that they don't know what the other GREMLIN members are doing so doing so would prevent the possibility of them meeting with him. She then tells Touma where he is. After hearing of Carissa's intention to use the Curtana's shard against Othinus, Touma slams his fist into the floor, destroying it with the Imagine Breaker and causing them all to fall down to a lower level. Seeing this as a hostile action, the four move to attack him.
To her surprise, Touma moves himself into the path of her attack, such that it would kill him if it connected. Moving to avoid it, Kaori tries to incapacitate him without killing him, realizing that he was using her own trait of not killing against her. However Touma curls himself up, forcing her to jump over him and ends up colliding with the Knight Leader.
Touma once again slams his fist on the mobile fortress, causing them to all fall down again. As they land to safety on the lower levels of fortress, Carissa comments on the queerness of Touma's actions as he can't escape the fortress from 1500 meters. William comments on Touma's plan on using Kaori against them. Both Carissa and Knight Leader find out that Kaori is gone. Carissa comments that they could try searching every room in the fortress and that Touma will be cornered eventually. However, William says they don't have time for that as he already realized Touma's plan, though says that it relies on others too much to call it a proper plan. And that plan is for him to use Kaori's character and trait of saving people to help him survive and escape.
Carissa later uses her Curtana shard to attack them and Othinus from afar, though Kaori later manages to divert the power being relayed to the Curtana's shard and destroy Hotel Ariel. Touma's gamble continues even after Touma left Kaori's side, as she fights Carissa, William, and the Knight Leader on her own. They later listen to the speech by Roberto Katze and Queen Elizard regarding the need to not give in to fear and hatred against Othinus, while Kaori continues to fight the other while coughing up blood from the attacks she had received.
Even without Curtana Original, Carissa demonstrated that she quite capable fighting with or against an entire group. Her intellect is also quite remarkable as she easily countered her opponent's tactics and abilities. With Curtana Original in hand, she fought nearly on even grounds against three Saint level opponents, and eliminated all her possible openings by exploiting the weakness in the group unity.
Other abilities she demonstrated with Curtana Original are:
- Sever dimensions with a cut
- She could run from Folkestone to Buckingham Palace by running as fast as a helicopter
- Strength almost equal to an angel
- Move and fight at supersonic speed
- Create a shield that can easily withstand blasts from a limit lifted sky fortress
Curtana's Dimensional Cleavage Formula, like other spells such as Stiyl's Innocentius, can't be blocked by the Imagine Breaker at times; but Kanzaki Koari mentioned to Touma in Volume 18's climax that if the Imagine Breaker comes into contact with the dimension cutter attack within 1.25 seconds of its activation, it can be stopped. After that, the attack becomes after-effects of magic and can't be blocked - with the metaphor given in the narratives as Touma can negate magic fire, but can't negate the ash it leaves. Knight Leader commented that Carrisa could use all the powers he had with Hrunting all at the same time whereas he could only use them one at a time.
