**Itsuwa** (五和, *Itsuwa*?) is a side character introduced in *Toaru Majutsu no Index*. A seemingly shy girl of the Amakusa-Style Remix of Church at first, she later shows her mettle and effectiveness as an ally of Kamijou Touma, eventually becoming his primary love interest.

## Etymology

Her name is derived from the real world town of Itsuwa in Kyūshū, which was later merged with other towns to form Amakusa City in 2006.

## Appearance

Itsuwa is described as a young Japanese girl with black hair (depicted in visual media as purple) that reaches her shoulders. She wears her hair in a bobcut with short fringes. Kamijou Touma, upon first meeting her, references that she has double eyelids, the first feature he noticed on her.

Itsuwa is rather well-endowed but is referred by her Amakusa comrades as hidden. Her clothing consists of things that allows her blend with her surroundings more readily, such as her sleeveless tank top—capris combo or her tank top over sweater with pants that seem to be cut apart. During her mission in Avignon, she was forced to wear skimpy clothing because she had nothing else to wear after jumping into the river to save Touma.

Her age is unknown but is still a minor (to drink alcohol), despite being able to pilot a helicopter, drive a motorcycle, and boat, and being referred to as being around the same age as Touma.

## Personality

Itsuwa is generally very friendly and warm, though quite modest. The narrative of the novel has described Itsuwa as "a totally ordinary girl" and she seems to be very humble about herself not only in personality but also in appearance, referring herself as "who is only charming with a hint of maturity," apparently allowing her to go to a bar without being interrogated, and that she can not compete with gorgeous women such as Kanzaki in the looks department, many of the Amakusa support her and assure that she has charm. She is skilled in housework and cooking, the latter being taught by her mother and even enough to impress Tsuchimikado Maika.

She seems to have developed romantic feelings towards Touma, but due to her shyness she has not been able to act on them or convey them to him. She is described as a girl in love, and has even shown to even challenge her Supreme Pontiff, Kanzaki Kaori, when it comes to pursuing Touma, despite only hearing rumors from Saiji. Touma notices that Itsuwa is different from the girls he is usually in contact with, as Itsuwa is not prone to violent outbursts when upset and is more inclined to proper, softer lady-like responses regardless of the situation she is in. She also has been described as someone who matures too late.  Her pursuit of her love interest is very innocent and slow, a fact that is mentioned by one of her comrades as her charm regarding her constant use of the "hot towel" technique for Touma. She easily gets flustered by direct contact such as holding hands or being hugged while she drives a motorcycle. Tsuchimikado Motoharu speculates that Itsuwa would dare to wear the Erotic Fallen Angel Maid outfit without a second for Touma compared to Kanzaki, though as shown later, even she is on the fence regarding erotic outfits.

She also easily gets taken away by her emotions, as when she becomes depressed after being unable to help Touma from being beaten by Acqua of the Back, to the point that it took a stern lecturing from Saiji to bring her back to her senses, and later became very enthused in proving Saiji her worth in protecting Touma by preparing her weapon, though scaring Saiji and her other comrades in the process. When down in the dumps, she takes to drinking despite being a minor.

In a mission she becomes serious, and as a member of the Amakusa Church where teamwork is key, she becomes a very reliable ally.

## Background

As part of the Amakusa-Style Remix of Church, she most likely resided in Shimabara, Kyushu most of her life with her comrades, and may have been witness to the many deeds of her Priestess before she left.

By the time of their introduction into the main story, they are well known enough for even people like Orsola Aquinas to seek refuge to. However, they still wanted to join Kanzaki, as is the reason why Saiji wears St. George’s Cross on his shirt, to show that they want to join her. As the focal point of the Saint Destroyer spell, she is most likely present during its creation, in an attempt to truly know of the strengths and weaknesses of Kanzaki in order for them to stand by her side.

## Chronology

### Toaru Majutsu no Index

#### Orsola Aquinas Rescue Arc

*Main article: Orsola Aquinas Rescue Arc*
Although she is only to implied to have been present during the arc, being one the 52-combat ready Amakusa Christians, in both anime and manga adaptations she is present.

Itsuwa and the rest of the Amakusa Christians were on a pursuit of a woman named Orsola Aquinas of the Roman Catholic Church. Stiyl Magnus, a representative of the Anglican Church, suspected that Saiji and his group have kidnapped Orsola Aquinas and Book of the Law to achieve ultimate power. However, the truth was that they were trying to help her escape, but she could not trust them as they were melee fighters who carried weapons. The Amakusas continued on their pursuit of her and eventually recaptured her in an encounter with Stiyl Magnus, Index and Kamijou Touma, who represent the Anglican Church, and the Agnese Forces led by Agnese Sanctis on a neighborhood just outside Academy City gates. In order to escape their pursuant, Saiji utilized a magical portal located on the nearby Parallel Sweets Park and waited for the exact time they could use the portal to teleport away from the scene. However, the Amakusas' location was spotted by the two forces. Itsuwa and the rest of her comrades are later captured in the ensuing scuffle. Itsuwa and the others are later kept in the Church of Orsola.

After Saiji is freed by Touma and company after the Roman Catholic Church forces revealed their true nature, Saiji goes on to save Itsuwa and the others while Touma faces the Agnese Forces on his own. She later gets involved in the Battle of the Church of Orsola. Saiji later has his comrades place Stiyl's rune cards all over the Church of Orsola grounds to create a large magic circle as so Stiyl can summon Innocentius. It was part of Touma's plan and he later discovers the nuns being cowed by Innocentius as well as their leader being cornered. Saiji later witness Agnese Sanctis' defeat at the hands of Kamijou Touma.

As part of Laura Stuart's plan to tether Kanzaki Kaori's loyalty, she allows the Amakusa Christians to join the Anglican Church. Itsuwa and the rest then began living in London's Japantown. There, Itsuwa does work for a bento shop on the first floor of the apartment complex she resides in when not in missions.

#### La Regina del Mare Adriatico Arc

*Main article: La Regina del Mare Adriatico Arc*

When first introduced into the series, she appears alongside other members of the Amakusa-Style Remix of Church to aid in Orsola properly move her wares from her house in Chioggia before permanently staying in London as part of the Anglican Church. This is when she properly meets Touma in person for the very first time, after hearing from the other members of the church of Touma's prowess, facing 250 battle nuns on his own before back-up arrived from the Amakusa Church, Stiyl and Index. All of the Amakusa Christians seem to show respect to Touma after hearing that he has also fought Kanzaki, seen her totally naked, received her Nanasen and has somehow managed to walk away from said incidents alive. She takes an immediate liking to him and starts trying to get closer to him by giving him a hot towel. However, every time she sees Touma might be in need of the usage of a towel or a napkin, her eyes shine in a strange way and she blushes strongly upon what she perceives as a "chance" to carry on with her "getting close to him" strategy; a usual comic foil of the series is Touma obtaining a napkin from someone else when Itsuwa was ready to hand him one. This fact of being unable to progress with Touma is noted by one of her Amakusa comradres as part of her charm.

As part of the Amakusa Church, she aids Touma and company in saving Agnese Sanctis and her Agnese Forces, despite being former enemies, indicating that they are faithfully following their Priestess' example, that they should always aid all those in need, as well as stop Biagio Busoni and his Queen's Fleet from destroying the science side. In the Battle of the Adriatic Sea, she boards of the Queen's Fleet ice ships and fight off the former Agnese Forces as Touma, Orsola, and Index go to the La Regina del Mare Adriatico to stop Biagio and save Agnese.

#### Anglican Church–Russian Orthodox Church Prewar Conference

*Main article: Anglican Church–Russian Orthodox Church Prewar Conference*
Apparently a few days before the two great Churches come together for a meeting for the War, the Knight Leader goes towards Japantown where the Amakusa live and asked for Kanzaki, wanting to invite her to a dance. However, Saiji who was there states to him that it wasn’t going to happen and they got into a heated argument. In the middle of all this, Saiji shooed the Knight Leader away with his hands telling him that Kanzaki prefers to lead younger guys than to be led by older guys and then mentioned that Kanzaki has already someone she loves in Academy City. Itsuwa is also present, telling herself to do her best.

#### Document of Constantine Arc

*Main article: Document of Constantine Arc*
The Amakusa Christians is requested by the Anglican Church to investigate the leylines and other magical properties of the land in France after a series of riots erupts around the world against Academy City. The 52 combat-ready members of the Amakusa Church go towards major cities in France, with Itsuwa in charge of Avignon. Her original task was simply to investigate, and once she has enough information she is supposed to contact Saiji so that a large team can gather and break in at once. She later becomes suspicious of the Palace of the Popes, the Palais des Papes, but decides to gather more information before gathering her comrades.

After Tsuchimikado Motoharu and Kamijou Touma is recruited by Oyafune Monaka to stop the riots, they travel to Avignon and parachute towards the city in order not to draw the Roman Catholic Church if they try to land the plane on French ground. Touma almost faints after being strangled by his own parachute strings after parachuting from their plane. Itsuwa rescues him before he drowns. It is discovered that Amakusa Christians are gathering infos in France on what is causing the disturbance, and Itsuwa finds Touma seemingly by pure coincidence as shown by her not knowing about why Motoharu and Touma are there. Itsuwa tells him that she needs to get her bag, but Touma asks if she has any other change of clothes with her wet clothes made her other parts visible. Itsuwa later changes clothes that reveal a bit of her cleavage, as Touma stares at her silently, she curls up slightly. Touma tells her that it's okay because of the way Kanzaki Kaori dresses but rebukes him that she doesn't dress in a lewd manner like her. Just by saying such words were enough to make her blush in embarrassment. Itsuwa tells Touma that since they're both after the C-Document they should cooperate and since he can't contact Motoharu he agrees.

The two sit at a cafe to have a bite to eat, regroup and plan their next move. Itsuwa asks Touma if he was able to contact Motoharu but no luck contacting him due to distance. After eating Touma asks her what she was investigating and she tells him that in Avignon there the largest Roman Catholic facility there called the Palace of the Popes. She shares a little bit of history of the place and the reason why investigating the connection between the Vatican and the Palace is important. There it it is revealed that Avignon has a ley line, a pipeline that runs from the city back to the Vatican created back during the Avignon Papacy in order to facilitate rituals that can only be done in the Papal State (before the Vatican was established) without needing to leave Avignon. Touma asks if she's been inside but tells him that she hasn't and the her and the rest of the Amakusa planned to after gathering the necessary information. Touma feels like the place might be suspicious and asks Itsuwa if there was anyway he can help her. Before she could answer an army of protesters try to attack Touma and Itsuwa but the two manages to escape.

The two are spotted by an angry mob before they can actually plan anything out. It seems that their animosity towards Touma comes after seeing him drop out of the plane, making Touma logically conclude that the Roman Catholic Church forces in the Palais des Papes are using the C-Document to hunt them down. Touma and Itsuwa start moving toward Palais des Papes, needing to destroy the C-Document before the magicians could escape as they could use it again. While dodging the mob to get there, Tsuchimikado Motoharu contacts them. It is revealed that he too is on his way to Palais des Papes, but a wall of angry mobsters block his path. Touma reveals to Motoharu regarding his knowledge of the Palais des Papes. There, he tells Touma and Itsuwa to sever it, banking on getting to the palace and calming down the rioters and immediately going to the palace before the magicians could leave, Touma and Itsuwa decide to alter the magical pipeline connecting Vatican and Avignon which allows the document to activate instead. This pipeline is basically a flow of energy that runs throughout the globe, and either Itsuwa or Tsuchimikado is needed to alter its path away from Avignon. The two end up at one of the city's many museums. Touma thinks about breaking the link using his Imagine Breaker but is told by Motoharu that it might not work on the natural mana flow of the land, as there are exceptions to what the Imagine Breaker can negate.

As Itsuwa prepares to user her Amakusa brand of magic to alter the ley line, she hesitates after realizing she has to use a pair of panties for it, though quickly made up her mind. After lining up the magic circle, an arpeture appears on the floor, and Itsuwa merely dips her Friulian Spear into it, and as she is about to turn her spear to alter the ley line. Terra of the Left, one of the God's Right Seat attacks them, destroying a wall in the process. The attack leaves Itsuwa's Friulian spear broken, which she immediately replaces. Terra of the Left appears before them and attacks Touma, and is surprised on how he manages to negate his flour guillotine. As Itsuwa and Touma become wary of him, Touma asks for Terra of the Left's identity, to which he easily says as he gathers his flour back into a form of a blade. The fight moves to the outside, and here Terra of the Left shows the wanton destruction his blade has upon the streets. Touma intended to draw Terra's attack and Itsuwa would get in range to attack him. Here, Terra realizes that he is dealing with the Imagine Breaker, the one that defeated Vento of the Front. He swings the blade towards Touma who lets out his hand, but Itsuwa intercepts the blows of the blade herself. She tries to strike Terra of the Left down but he is fast enough to swing his blade towards her and buy him enough time to attack again. Suddenly, he notices steel wires surrounding him, and Itsuwa uses her Seven Blades of the Seven Teachings technique to cut him down. There however, Terra of the Left uses his "Precedence", his Execution of Light spell for the first time in front of them, making him immune to the wires. Initially shocked, Itsuwa nonetheless tries to stab Terra of the Left again, but uses his "Precedence" spell to disappear in to phase through the wall behind him, making her miss. Using Precedence again, he destroys the wall with his guillotine, forcing Itsuwa to dodge. Seeing this, he tries to attack her in her vulnerable position, but Touma intervenes, and his blade is once again destroyed. Using his spell again, he gathered the blade back, and used it to strike down the wall on them, forcing Touma to take Itsuwa to avoid the falling debris.

Terra of the Left states his disappointment on Touma's Imagine Breaker, concluding that Touma only won against Vento of the Front after Touma destroyed her Divine Punishment, summoned the "fallen angel", and brought out a strange realm to pressure on her. Here, Touma realizes that a member of God's Right Seat who is on the same level as Vento would not attack with just a blade, and became disturbed by him. Seeing this, Terra of the Left mocks him, and states to him that he should at least allow him to enjoy their little situation a but more even if what he is facing is the best Touma has. Then, Touma and Itsuwa attacked simultaneously. Using his spell, Terra stopped the movements of Itsuwa's spear, stopping it in mid air. Touma attacks but Terra is faster, and the blade hits Touma's body but it does not cut him as he expected though he is still hurt by it. Touma then punched the guillotine that hit him and it is once again destroyed, causing Touma to think more about the implications of Terra's spell. As he re-gathers his flour, Itsuwa states that Terra's power is Precedence, to which Terra explains to her the symbolism used for his blade, the mythology associated with Christ's death, and it, being the reason why he has the Precedence spell. It is based on the secret ceremonies required to complete the story of the Son of God is the alteration of the order of precedence, the Execution of Light, and flour he shapes into a blade as medium is a by-product. After his explanation, he is confident that them despite knowing of how his abilities origins and mechanics, he can still defeat, and he was right. He then gives them time to make a up a plan for his entertainment.

Suddenly, Tsuchimikado Motoharu arrives and shoots an magical origami figure at him, though Terra simply uses his Precedence spell to make it bounce off him, landing the thing near Itsuwa. Motoharu declares that he has cornered Terra of the Left now. He takes the handgun he took from Oyafune Monako a while back, and as he shot Terra, he quickly predicts what Terra was going to say for his spell. Motoharu, confident that he can beat Terra, boasts that he can beat him and takes out a black origami figure, and Terra can only watch in silence. As Itsuwa relates to Touma that Motoharu wants them to go to the Palais des Papis at the same time Terra and Motoharu starts making their move, explosions ring out, the invasion of Avignon has begun.

##### Academy City invasion of Avignon

*Main article: Academy City invasion of Avignon*
Although annoyed that his battle with Motoharu was interrupted, as he wanted more battlefield data for his precedence spell, Terra of the Left quickly escapes them during the attack by Academy City's HsPS-15 Powered Suits. Seeing that Academy City is simply attacking civilians, though non-lethally, dumbstrucks Touma, and reminds him of why Monaka may have asked her to help stop the protests in the first place. Itsuwa tries to check on Touma asking him if he is all right as she helps her out. Motoharu calls out to Touma and tells her to go to Palais des Papes. Touma asks if it's all right to leave without doing anything seeing as it is Academy City that is attacking, to which Motoharu says that going after Terra comes first, and that the Academy City forces are after the Document of Constantine as well. Motoharu tells Touma and Itsuwa to go to the palace, seeing it as the only chance to destroy the document. Motoharu then says that he will stop the Academy City forces and negotiate with them. Annoyed, Touma and Itsuwa is forced to go to Palais dep Papes, leaving Motoharu behind.

When Touma and Itsuwa reach the empty Palais des Papes, he contacts Misaka Mikoto regarding current events with Academy City, Terra throws an HsPs-15 Powered Suit towards the building, destroying a wall and knocking his phone out of his hands. There, he comes upon Touma and Itsuwa again, dismayed at the attacks stopping the spell, and says that are retreat would be the best option. Touma and Itsuwa obviously doesn't want him to leave, but mocks at their powerlessness, challenging them to stop him.

There battle begins as HsB-02 planes use their Earth Blades to melt the ground around Avignon. They ignore the attacks going on outside and do battle. Touma and Itsuwa move first but Terra quickly uses his spell that forces Itsuwa to help Touma dodge Terra's attack, which tears apart the palace. Itsuwa then manages to strike Terra but he used his spell to make blades not work on his skin. The force of the attack knocks Itsuwa down taking Touma with her. She is hurt by the debris and Terra takes advantage of that fact, he makes flour have a higher precedence to human skin, swinging down his blade towards her. However, manages to destroy it before it reaches her. He tries again and Itsuwa just pushes Touma aside, making Terra miss. Terra mocks her for getting in Touma's way. Itsuwa agrees, but says to Terra on how he has revealed his fatal weakness. Terra uses his Precedence again to make the ceiling collapse with his flour, forcing Itsuwa to hurriedly wedge her spear between the ceiling and floor. Without her weapon Terra attacks her, hitting her body and knocking her out. The ceiling then returns to normal and Terra gloats over his victory.

For much of the fight between Touma and Terra, Itsuwa is unconscious and is unaware of Terra revealing that Touma has lost his memories. Later, after Touma has already defeated Terra and is interrogating him about what exactly Imagine Breaker is, an attack from an HsB-02 blows the two of them away. Itsuwa regains consciousness and finds Touma again knocked out and injured by the explosions caused by the HsB-02. Parts of the room are seen to have actually melted due to the sheer amount of heat and are covered in steam.

Itsuwa overhears a figure speaking just as she is about to start tending to Touma. The figure is speaking with one of the higher ups of Academy City over the phone, telling them to send troops to come search for Terra's corpse and run DNA tests to see if he's really dead. She stays hidden, not knowing if the figure is friend or foe, steam giving her enough cover so as to not be seen. The figure leaves soon after to a deeper part of the palace. She states that she finds the figure, who can stand in flames like that, even more terrifying than Terra.

#### Acqua of the Back Arc

*Main article: Acqua of the Back Arc*
Two days before the start of the arc, the Anglican Church and Academy City both receive letters from Acqua of the Back threatening that he will crush Touma, and warns them that if they intend to stop him, then they must prepare to use all their power. Moreover, he sends the corpse of Terra of the Left to the Anglican Church prove the letters' authenticity, and Itsuwa is then called to confirm Terra of the Left's identity, having fought him in Avignon. Because of this threat, the Amakusa Christians were sent to protect Touma, since they can be used as a scapegoat when things get bad and that since they're based on Japan it gives them a geographical advantage.

As a set-up by the Amakusa Christians to get Itsuwa to become closer with Touma, Itsuwa is tasked to be Touma's bodyguard. Itsuwa is first seen outside of Touma's school and discovers much to her surprise, a large man chasing Touma. Mistaking him to be Acqua of the Back as she has never seen him before, she tries to attack him. The chase is brought to an end, and Saigo is apparently forced into a retreat due to "health" reasons, much to Touma's relief, allowing him get lunch. After class, Touma speaks to a saddened Itsuwa, embarrassed by her mistake. Itsuwa asks Touma if he knows who Acqua of the Back is, to which he informs her that he has met him back in September 30. Itsuwa later tells Touma that Acqua's target is him, saying that the Anglican Church and Academy City has received letters of challenge. Touma is doubtful with Acqua of the Back going after him after Vento of the Front telling him on how the Pope required many documents to have people attack Academy City. Itsuwa points out that it is because that Touma had a hand in stopping their nefarious plots that they have Acqua of the Back after him. Itsuwa notes that the British Library is checking on his history, and though there is not much to go on, concludes that he must be powerful to be included in God's Right Seat and has the strength of a Saint, and wishes for Kanzaki to aid them. Itsuwa points out that fighting in Academy City should be a great advantage, as both Vento of the Front and Terra of the Left gave them opportunity to fight back due to interference of science. Still though, Touma says that he doubts that it would be that simple. Itsuwa tries to reply but can only mince words and in a flustered states says that she will be protecting him as they have been given orders by the Anglican Church. Touma asks again why Itsuwa is there with him, as he does not believe what he has heard. She then reiterates that she is his bodyguard.

Meanwhile, the Amakusa Christians bored with Itsuwa's slow pace in getting together with Touma plans to have him plant his head plant on Itsuwa's breasts. He is successful, but he manages to catch the attention of Misaka Mikoto, irate on what had happened to Touma. Saiji and the other later leave quickly without a trace. Meanwhile, Itsuwa doesn't know what to do, she is flustered and tries to rub the part of Touma's head. Mikoto dashes towards Touma and attacks him using her Electromaster powers. In order to fulfill her job, Itsuwa started to assemble her spear, and in order to stop her, Kamijou hugged her, leading to Mikoto becoming angry again, forcing Touma run around Academy City.

Itsuwa arrives in Touma's dormitory, leading to Index questioning why she is there. Itsuwa tries to explain to Index regarding God's Right Seat but is told to be quite about it by Touma around in Index as he doesn't want her involved. Itsuwa understands but is flustered after Touma took her away by the wrist. As Index becomes incensed, Itsuwa notices Sphynx, and gives it high-class cat food as a present. Touma notices the various foodstuffs in Itsuwa's bag, to which she claims is that despite her being a bodyguard, she shouldn't just eat and drink for free, telling Touma to entrust her with the housework. The atmosphere completely changes as Touma becomes enthusiastic, much to Index's surprise. He shows Itsuwa the wok for her to use Itsuwa's presence greatly lightens Touma's mood. Itsuwa then begins cooking much to Index's excitement, and tries to bother Itsuwa for it. Having none of it, Touma shouts at Index to "stop ruining a man's dream," and tells Index to follow Itsuwa's example. He forces Index to clean the bathroom while they wait for Itsuwa to finish her cooking. As Touma begins to do some housework himself, there Tsuchimikado Maika smells the scrumptious smell of the miso soup. Maika is able to automatically pinpoint the special ingredients Itsuwa made, much to her bewilderment, and acknowledges Itsuwa's skill. Seeing to one up her, she returns to Motoharu's room and throws away the cream stew she prepared for his dinner, in order for her to make a much better miso soup. Itsuwa hears Motoharu's cries, and recognizes it as from the incident in Avignon but is unable to confirm it.

After dinner, Itsuwa suggests going to School District 22 for a bath to the Spa Resort Serene Springs after Index destroys the bathtub in her attempt to clean it. With the last bus already leaving, Itsuwa takes Touma and Index using a rented motorcycle with a sidecar, leaving Sphynx with an expensive scratchboard to play with. With Itsuwa speeding, Touma is forced to grab Itsuwa's waist even tighter as he is riding behind her, making her happy. They later enter the district to which Itsuwa relates to Touma on her surprising knowledge with the City. There, Itsuwa bathes with Index and comes upon Misaka Mikoto. Mikoto becomes noisy in the bath but is promptly scolded by Index. Mikoto recognizes Itsuwa as the "girl who got hugged by that idiot because of some strange soccer ball," making Itsuwa embarrassed and ebb into the water. Mikoto starts to wonder if the two know about his memory loss and while pondering about the issue again, she faints in the bath and Itsuwa and Index is forced to call the staff to have her resuscitated.

Leaving Index back in the bathhouse who wanted to taste some of its food there, Itsuwa accompanies Touma for a walk. Here, she and Touma talk about the Amakusa and their life in England, and later moves to Itsuwa and Kanzaki's clothing. Itsuwa then talks using the metaphor of Vega and Altair (Orihime and Hikoboshi respectively, the star-crossed lovers of the Tanabata) to describe her relationship with Touma, not being able to see him, though Touma doesn't understand. Here, they are unaware that Acqua of the Back has appeared before the Amakusa Christians and utterly defeated them. The two continue to talk, with the topic flowing towards Acqua of the Back, God's Right Seat, and the role of the Amakusa Christians in protecting them. They later move to a bridge, and after Itsuwa blushes at the thought of them being alone together, they note their queer situation. There is literally nobody other than the two of them. And there came steps from the darkness and it showed Acqua of the Back. He reminds them of his warning, but since they've chosen this path he tells them that he will use all of his strength to crush them. Acqua of the Back says to him that he has come to crush him, the reason for all the unrest in the world. Touma calls him out on this, and references what they did to Avignong. But Acqua would not yield, and points that what happened there only happened because of Touma and his Imagine Breaker. He then tells Touma to hand over his right hand if he wants him to spare his life. Itsuwa asks about the Amakusa Christian, to which Acqua says that he did not kill them for what he wants is not them. Despite Touma and Itsuwa's concentration, they are caught unaware. Acqua sends Itsuwa flying with a single hit, allowing him to attack Touma with his giant mace that he summoned. Fortunately, Itsuwa somehow flings her bag between them, sparing Touma for the moment from the large mace despite the debris hitting him. But the sheer power of the blow flings Touma high up and then hitting the metal frame of the bridge, making him fall. Itsuwa hastily assembles her Friulian Spear, and she prepares to fight despite being damaged from the previous attack. Acqua of the Back points out the folly of challenging the man whom her entire group couldn't beat, but Itsuwa would not yield. Seeing this, Touma tries to stand but is unable to as Itsuwa and Acqua fight in high speed. But it is quickly over as it had begun, and Itsuwa is hit with the mace and then tossed towards Touma, hitting him. Touma understands the situation, that he could not hope to match against Acqua even after he fought Vento of the Front and Terra of the Left. Acqua of the Back once again asks for his right hand, but Touma doesn't cooperate, prompting Acqua to attack him again. Itsuwa regains consciousness after Acqua of the Back pummels Touma to the point of drawing blood. Touma appears before a bloody mess. She is horrified by this, at which point Acqua notices her, telling her to move or she'll be caught by the tremendous power of his attack on Touma. Itsuwa breaks down and desperately tries to heal Touma in spite of his right hand. But it is vain due to the Imagine Breaker, and Itsuwa can only cry. Acqua of the Back tells her that it is enough, and steps on her back, silencing her cries and moans. As Acqua tries to come towards Touma, a screaming Itsuwa raises up her arms against Acqua again, trying to protect Touma. Acqua sighs as he and Itsuwa prepare for the inevitable conclusion of their clash. However, before Acqua can strike him down, Touma once again stands by her side. He thanks Itsuwa for the healing magic despite her knowing it did not work, and in her shock, cannot stop him from going towards Acqua of the Back, to protect her. To save Itsuwa, Touma alone stand against Acqua, impressing him. Acqua of the Back deals a horrendous blow upon Kamijou Touma, but does not kill. Touma is hung upon the mace. Acqua of the Back smiles at Touma's courage, and tells Itsuwa that he is giving them one day more. He tells her that he will give them one more day to choose whether or not to give Touma's right hand, and if they did, he will spare their life. Afterwards, Acqua swings his mace that had Touma on it, flinging from the bridge and into the cold water at high speed, and finally sinking after bouncing from it several times. Without confirming whether his target is dead, Acqua turns his back on Itsuwa for one day more.

## Abilities

### Amakusa-style abilities

*Main article: Amakusa-Style Remix of Church#Abilities*
As being part of an Amakusa, all of what Itsuwa wears is part of her magic and is deliberate. The Amakusa Christian’s specialty is secrecy, since they’re Christians whose nature is to deceive others; they hide the teachings of Christianity inside Shintoism and Buddhism completely, and are particularly skilled on a brand of Idol Theory that allows them to cast spells using symbolism hidden in body movement and everyday items. They cover all their tracks so that others won’t even notice their existence. These teachings have been passed down from generation to generation.

### Friuli Spear

Like all the Amakusa Christians, Itsuwa carries a weapon. Her signature weapon is a **Friuli Spear** or **Friulian Spear** (海軍用船上槍 (フリウリスピア) , *Kaigun-Yō Senjōsō (Furiuri Supia)*?, lit. "On-board Lance for Navy") that is apparently used in navies. The spear is most likely a reference to the coat of arms of the capital of the Friuli-Venezia Giulia region of northern Italy, Trieste, which bears a spear or properly referred to as the corseque. The spear is 70 centimeters long. The spear's grip is split into 5 parts that came together into a single rod when connected using their sockets that looked like gas valves. When she needs to use it, she can connect the attachments making a single spear, allowing for concealment and ease of carry at the cost of the spear's strength. The pieces are replaceable after they are broken allowing for Itsuwa to remake the spear even when it has been broken.

She is able to wield it expertly, able to take down several enemies with a single swing, and relieve a cornered position with it, as what she had done for Lucia during the Battle of the Adriatic Sea. However, she is most effective in team situations, unlike the human wave tactics that the vast Agnese Forces use, the Amakusa Christians, with its at least 52 combat-ready members, have been shown to be much more focused on teamwork and unity. Indeed, during their protracted battle against Acqua of the Back, Itsuwa with her spear was the focal point of their strategy.

### Known spells

Despite her magic being the same as that of her Amakusa comrades due to their shared history, Itsuwa has show spells that are either unique to her or is most well-known because of her usage.

#### Saint Destroyer

The **Saint Destroyer** (聖人崩し, *Seijin Kuzushi*?, Yen Press: **Saintbreaker**) requires the Amakusa Christians to set-up a formation, with the attacker at the center, the Saint Destroyer is a magic attack that works on Saints alone. On a normal Saint it will only cause them to be unable to move for several seconds, but for someone like Acqua of the Back who who has the attributes of the Son of God and the Divine Mother, he will surely self-destruct. Itsuwa alone is shown to be the only who is capable of casting this spell. It is because her wielding a spear, it is a reference to the spear that stabbed the Son of God, the Spear of Longinus as explained by Idol Theory, a weakness of the Saints. The attack requires for her to use a tube using a towel with her spear in order to reduce the friction between her palm and spear when pierces the opponent with it.

It appears as blueish-white purple electricity, causing an explosion, and the electricity forms into a Cross, the weakness of Saints through Idol Theory, as Saints have a body that is similar to the Son of God who was crucified on a cross and was pierced. Explosions continue to occur after the magic attack is dealt. Other additions can be appended to increase the strength of the spell, specifically they should be related to the Son of God's crucifixion, such as a crown of thorns, a picket, and a large cross.

It was created by the Amakusa Christians after the departure of Kanzaki Kaori in order to understand the burden of being a Saint, and in theory, surpass whatever she feels as a threat.

#### Other spells

* **Ley line damaging spell**: Using found objects that serve symbolic properties according to Idol Theory, Itsuwa can use an Amakusa-style ley line damaging spell using her spear. After arranging the objects into a circle it will glow, and Itsuwa merely needs to strike her spear deep into the circle and turn it like a key until the ley line is disturbed to her needs. Severing a ley line completely, however, requires a lot of people working together.
* **Seven Blades of the Seven Teachings** (七教七刃, *Shichikō Shichijin*?, Yen Press: **Seven Teachings, Seven Blades**) is a technique used by Itsuwa using steel wires. It is similar to Kanzaki Kaori's Nanasen, as it uses 7 steel wires that acts as superfine blades to attack a target at once at 7 different directions. It is unknown if it is just Nanasen using a different name, or derived from it. Itsuwa uses her spear instead of a sword to use the technique.
* **Healing Magic**: Itsuwa gathers nearby everyday items to cast healing magic. For example, she used a handkerchief, pieces of debris and Touma's wallet to cast a spell that created dim green glowing little balls that enter a person's wounds to stop their bleeding and replenish their lifeforce.
* **Damage transference charm**: A spell based on the meaning of clothes and why they are created, "to protect a person's body". The charm automatically transfers part of the damage she takes to her clothes to weaken enemy attacks. She also has a spell that uses a piece clothing as a scapegoat to completely avoid an enemy's strike.
* **Icy Night Wind** (冷たい夜気, *Tsumetai Yaki*?, lit. "Icy Night Air"): A spell cast on the tip of Itsuwa's spear, creating an explosion that can tear apart asphalt.
* **Reproductivity that Plants Possess** (植物の持つ繁殖力, *Shokubutsu no Motsu Hanshokuryoku*?) or **Scattered Grass** (雑草, *Zassō*?, lit. "Weeds") is a spell that Itsuwa uses to exponentially improve her spear's durability by adding about 1,500 layers of reinforcement through resin, which symbolizes the age of trees. It uses an image of the growth of plants and amplifies the hardness and endurance of her spear with every passing second. Thought this spell takes prep time, it allowed Itsuwa to block Acqua's strikes when used in conjunction with her damage transfer charm.
* **White Explosion**: An apparently Christian-based spell based on the sun. After Itsuwa draws a circle in the air with her spear and recites a small chant, a pure white explosion takes place in two locations. The first explosion takes place along the circle drawn by Itsuwa's spear and the second on the enemy Itsuwa is facing. Chant: *"The power of heaven is always represented by the sun. Even in the depths of the earth where no light reaches, there is nowhere the Lord’s power cannot reach. Purify our peril with light as bright as midday!!"*
* **Imitative Magic:** Itsuwa makes uses of a large variety of magical symbols in her spells, which fall under this form of magic. She uses such symbols for both spells which have been devised in advance and ones which have been devised on the spot. An example of the latter would be when she matched the movements of Cynthia Exment, who was an Amakusa herself, and used her spear, which had lost its tip, to represent Cynthia's staff, into which data on the spiritual items in the British Museum had been downloaded, in order to duplicate the staff's function to shift into those spiritual items.
* **Life force concentration spell**: Itsuwa knows of one method that allows her to concentrate the life force needed to refine magic power and concentrate it on a single point. This is a standard method of creating a boost. Itsuwa used the spell to sever the connection and flow of power of a cursed wax doll that had taken her blood to read her life force, and in turn, make attacks that she couldn't avoid. The spell can only be used by women and is based on the legend of Adam and Eve
**The chant:**
*"This is the story of paradise before it was corrupted by sin."*
*"God created man and arranged to give everything to him, but the perfectness left the man feeling uneasy. The man could not live in solitude and the animals living in paradise were not enough to fill his heart.*"
*"God, being generous, was willing to use his power to fill the man’s heart, but the man did not choose that method.*"
*"That one man should have been enough of a beginning in paradise. Two starting points are not needed. Each subsequent man created from then one should have been a single point.*"
*"God pitied the lonely man and created a partner from his rib. That partner’s name was Eve. That is the name of the starting point and model for all women!*"
*"All women come from the missing rib and must join with their lifelong partner through marriage!!*"
* **Wax magic:** A very specific one, where they are able to create a "wax suit" based off a person of their choosing, where a person can "wear" it. This "suit" is apparently enough to fool Necessarius magicians.
* **Mandala:** A diagram with complex patterns that makes one think about the nature of the universe and the principles of the gods. When the patterns are rearranged it allows for the user's desired image to be sent to the viewer's head. In short: an illusion magic, though it can also be used to insert ideas into an enemy's mind such as "My curse spell has been analyzed and a countermeasure could be used to turn the curse back at me, so I won't use it".
* **St. Andrew's lightning spell:** A spell which increases the accuracy of Itsuwa's spear. To use it, Itsuwa carves an 'X', the symbol of St. Andrew, a patron saint closely related to lightning, on the spear's handle. She then throws the spear, which absorbs any lightning that strikes it and becomes a mass of bluish-white light which strikes the target. Chant: *"St. Andrew’s lightning will accurately strike the evil woman who looked down on the innocent young man!!"*
* **White Explosion:** An apparently Christian-based spell based on the sun. After Itsuwa draws a circle in the air with her spear and recites a small chant, a pure white explosion takes place in two locations. The first explosion takes place along the circle drawn by Itsuwa's spear and the second is the enemy Itsuwa is facing. Chant: *"The power of heaven is always represented by the sun. Even in the depths of the earth where no light reaches, there is nowhere the Lord’s power cannot reach. Purify our peril with light as bright as midday!!"*
* **Mass-based cutting open spell:** A spell which Itsuwa intended to use while wielding Tsushima's rapier, using the Christian symbol of a sword for cutting open and of Mass, where loaves were distributed evenly and where the bread represents the body of the Son of God. Itsuwa draws a circle on the ground representing the plate, then applies water to the rapier which represents a consecrated knife. She then has what is on top of the circle, the plate, be the bread which needs to be cut open, and uses the rapier to cut it open. This spell was intended to cut open Freadia Strikers' armour without damaging her life-force, though Itsuwa was unable to fully execute it.

### Other abilities

Itsuwa has an international license and she can pilot cars, motorcycles, mini-boats and (with difficulty) a helicopter.

## Relationships

### Kamijou Touma

Itsuwa has been in love with Touma ever since the La Regina del Mare Adriatico Arc. She relies on the advice of Tatemiya and the other Amakusas to get close to him. A common tactic of hers is to offer him a wet towel. She also gets excited by just a bit of physical contact with him, such as holding hands with him or getting hugged while riding a motorcycle together. Although initially embarrassed by the idea she later seems to take wearing the Great Spirit Revealing Maid outfit for him in consideration. It has been stated that Itsuwa is prepared to die for Touma.

### Kanzaki Kaori

Kanzaki is Itsuwa's superior in the Amakusa Church, and like all of the other Amakusa's she looks up to her a lot. Itsuwa considers Kanzaki better than her at everything, including looks. Despite this immense respect, she has stated that she will not hand Touma over to her or anyone else despite being aware of Kanzaki's feelings for him.

### Tatemiya Saiji

Tatemiya is also Itsuwa's superior in the Amakusa Church. Itsuwa relies on him for relationship advice with Touma.

### Design Evolution

Details in Itsuwa's design has changed as her prominence becomes more apparent in the later half of the *Toaru Majutsu no Index* series, though her overall design remains the same. According to Haimura, due to the theme of Amakusa wearing clothes that would not make them stand out, Itsuwa was drawn to wear features that would never be seen in reality, though are much more common in moe characters.

By volume 14, and in Itsuwa's new clothes for that volume, Haimura had the idea that the Amakusa's would try to keep up with the latest fashion to better help them blend in. For the volume 16 clothes change Ituswa has, Haimura states that since she is a moe-type character, her design must follow a "cute" style, and must not be altered too much. For Itsuwa's Great Spirit Revealing Maid Haimura wanted to give more symbolic aspects to obtain an easily understandable overall image of a fairy, but he states he couldn't come up with any clear ways of representing the idea of a fairy, so the design has that same vagueness to it.

Her clothes during Toaru Majutsu no Index SS: Necessarius Special Admission Test are pretty much the same as in Volume 14, but there are some minor changes like the gold bikini top and ring on the left index finger.
