IttoSara

"Oh, but, General. If you join the Arataki Gang now, I can show you what dreams are made of."

- Itto to Sara during his official character demo

IttoSara is the het ship between Arataki Itto and Kujou Sara from the Genshin Impact fandom.

Childhood
Itto and Sara share similar childhoods as both were orphaned at a very young age and were forced to raise themselves in order to withstand the harsh obstacles life has in store for them. It is revealed in Itto's Character Story on his in-game profile that the two fights that he will never forget both involve a Tengu as his opponent. The first having happened in his childhood where the two engaged in a sumo wrestling match atop Byakko Plain which resulted to the two tumbling down the mountain, rendering Itto unable to get up, thus, having the aforementioned young Tengu carry him back to town. While the other battle being the time he lost to Sara which resulted in his Vision being confiscated. It is heavily implied that the Tengu in his childhood is Sara herself, but because she was mentioned to have looked more like a boy in her youth, he does not suspect them to be one and the same.

During the Revolution
Itto's Vision was confiscated by Sara after he was defeated by her while the Vision Hunt Decree was still active. Ever since then, Itto has been determined to have a rematch with her. Throughout all of Inazuma, he proclaims his intent to duel with her by vandalizing bulletin boards, much to Sara's annoyance.

When talking to Uesugi, he talks about Itto and his plan to take revenge on Sara ever since she confiscated his Vision. Telling that Sara saw that he was very serious about the revenge and his fighting spirit was commendable, so they picked another day for the duel. But Uesugi told that somehow, Itto insisted that due to some weird Oni rules, the rematch must be a sumo showdown on the crossroads. However, the duel never happened as Itto was dragged away by a masked lady.

In the Ritou Bulletin Board, Itto calls Sara "Kujou Tengu" and messages her on the bulletin board, after he tells her to "stop harassing outlanders all the time". He notifies her to not forget the beating that she gave to him, telling Sara that she cannot escape their rematch. Sara finally messages him on the bulletin board, asking him to stop vandalizing the bulletin boards. She told that she will grant his wish upon the rematch once the war was over. She tells him to knock it off already, and told that she would've already sued for harassment if she wasn't an officer of the Kujou Clan.

In the Ritou Harbor Bulletin Board, Itto asks Sara if she ran away again, thinking that she must've fled in the night after hearing his name. Asking her if his name is scary in the battlefield, but Itto claims that it's fine as he shall wait for her return in the Harbor. Itto tells her to don't dare die on the battlefield as she still owes him a duel. Sara replies to his messages, shutting him and asking if he's done yet. She says if this was some kind of blessing before she sets out for war, then she shall accept it. She reminds him to not kill himself either, and calls him a "idiotic Crimson Oni".

In the Inazuma Commercial Street Bulletin Board, Itto tells Sara to stop hiding, telling her to crawl out of whatever hole she's in, and fight him fair and square. Someone replies on his messages, however it wasn't Sara who was the one who replied. They said that Sara promises that she has nothing to do with Itto, and that she will handle these messages immediately.

In the Hanamizaka Bulletin Board, Itto comes back, messaging Sara, asking her where she is. Itto tells that he will never forget that she confiscated his Vision away, saying that as long he breathes, he will still keep coming to her and reminds her to not forget that. Someone replies to Itto's messages, they replied the same thing, saying to not worry as they told that Sara has nothing to do with Itto.

Miscellaneous
In Yoimiya's Story 4, it is stated that the handmade knicknacks she makes are not just popular with the children, but are just as well-loved by adults as well, citing Itto as a prominent example. It is stated that Itto occasionally comes over to buy some of her handiwork to bring as offerings to "his self-declared nemesis" in hopes of instigating the long awaited rematch she promised him. Interesting enough, Sara has shown to have taken a liking to such trinkets, specifically a spinning top, after receiving one from a vendor in Hanamizaka.

In his official character demo, Sara confronts him in a flashback to when the Vision Hunt Decree was active, demanding that he surrender his Vision. To which he responds to her with an invite to join his gang, telling her if she accepts, he can "show her what dreams are made of". After the Vision Hunt Decree was over, Itto goes to the Statue of the Omnipresent God in order to get back his Vision, only to find it at the very bottom, under the pedestal, which greatly enrages him as he believes that it should have been at the top of the statue due to his strength. It is highly possible that Sara purposely placed it there to tease him.

The pair's Special Dishes also compliment each other, with Sara's "Faith Eternal" sweet egg roll befitting Itto's love for sweets while Itto's "Way of the Strong" mixed yakisoba bun fits the description of Sara's preferred "quick-filled meal".

When the player asks Riku, an NPC next to the Teleport Waypoint of the Narukami Grand Shrine, "What are you doing?" he describes observing what the other characters have wished for. With his last line describing that of "A big bro wishing for the Kujou Clan to be prosperous", possibly referring to Itto himself.

In Sara's "Good Evening" voiceline, she mentions how she adores the sight of the sakura petals at night in Hanamizaka, which is notably Itto's hometown. While Itto's "Good Afternoon" voiceline has him mention the Tenryou Commission (which Sara is in charge of) as a possible hang out spot before immediately taking it back for an unspecified reason.

In Sara's voiceline about Itto, she describes him as "the noisiest person she has ever met" before quickly correcting herself, saying that he's the noisest oni, instead. This implies she is talking about another oni, though this was before the introduction before Takuya, which only has Itto as the last known living oni (part oni, in his case). This means she could be indirectly referring to a younger Itto whom she may as well have also not be aware to be the one and the same person she had a duel with in her youth, making the two share the same circumstances of remembering having dueled with an oni/tengu respectively, but not piecing together that their current rival is one and the same.

Itto's Story Quest, the Taurus Iracundus Chapter, featured Crimson Cyclone (Paimon's large red Onikabuto) engaging in a beetle war with Stripy Ghost (Daisuke's regular-sized purple Onikabuto), seemingly a nod to how Sara and Itto's complimentary color schemes are that of purple and red while also taking note of the two's height/size difference.

It is worth noting that, while Itto has invited Sara to join the Arataki Gang right before their duel for his Vision, Itto's take on his gang is that they're "proud to welcome people who've experienced adversity in their lives," who highly discourage fellow members from taking insults to their fellow clanmates as "freaks" or "weirdos" to heart. And, how "every member of [the gang] is like family [to him]", with them also sharing the same sentiment. His closing statement being that "whatever happens, both the highs and the lows, the gang will face it together". This is befitting since, from an early age, Sara was conditioned to think her Tengu heritage makes her no better than a "freak” by her father, thus, isolating her from her peers.

Fanon
Fans have taken note of Sara and Itto's dynamic ever since Inazuma has been released, although the ship only started to gain traction after more information spread about Itto and especially after his design was revealed. People enjoy the rivalry aspect of their relationship, as well as the trope of the loud, active character shipped with the disciplined, analytical character. But while it has been getting more popular, its rival ships, namely KokoSara and IttoGorou, have also been getting popular. IttoSara currently has 195 works in Archive of Our Own.

A lot of fanart pokes fun at their relationship, featuring Itto demanding Sara's attention or being affectionate while Sara is annoyed. Another trope that can often be observed in fanwork is Sara being the dominant "girlboss" partner in the ship that has to keep the more active Itto in check.

IttoSara, at the time where it only started gaining traction, has already been in the spot of controversy. Some people have claimed their relationship is unhealthy and that Itto harasses Sara, but many disagree with this perspective as Sara is a perfectly capable woman who would not allow such a thing to happen if ever this were true and could easily defend herself when the time comes.

A possible explanation as to why he's the one and only Vision holder to not have lost his ambition after getting his confiscated was that he immediately gained his new ambition in wanting to have a rematch with Sara the moment she confiscated it from him, thus, him still appearing to not have lost his fighting spirit.

It is also heavily implied that Itto and Sara are the descendants of Iwakura Doukei the Oni fighter and Teruyo the Tengu warrior, rival-lovers who fought their last battle on Byakko Plain, instigated by Teruyo herself. After being bested by Doukei in battle, she tells him that she is afraid she must continue on with her duties, thus, telling him to kindly forget about her before bidding him farewell forever.

The alternate thought to Sara putting his Vision at the very bottom of the statue of the Omnipresent God was that, in addition to teasing him with it, she put it there on purpose so he would have an easier time accessing it, knowing full well that his Vision is very precious to him.

Because of Itto's love for sweets (especially for lollipops ), a popular headcanon amongst fans is that he would offer Sara a lollipop in hopes of relieving her stress, as she has stated in her "Least Favorite Food" voiceline that she dislikes sweets as they have a tendency to "make her unwind" which she deems as "slacking off".

Another popular headcanon from fans is how Itto will inevitably enter his rumoured "berserk mode" if ever he sees Sara heavily injured, losing all thought and reason due to going into his feral overprotective mode over the fallen general. As well as Itto only resorting to calling her by her actual first name (in distress) if ever she is permanently defeated during the war.

Because of what she reveals about herself in her in-game character profile, it is theorized that Sara, as a result, is terribly touch-starved. And because of this, it is highly accepted by the fanbase that Itto would undoubtedly shower her with physical affection without hesitation.

As a result of the two both having yokai blood in their veins, another highly accepted headcanon is how the two secretly admire each other's yokai traits, notably Itto's horns and Sara's wings (which she always keeps under wraps).

It is also highly theorized by the fandom that, during their childhood, they were each other's only friend due to Sara's strict upbringing and training and Itto being an outcast for being rambunctious and scarier than the other kids, on top of being an oni.

Another quite popular headcanon has fans believing that Itto carried an unconscious Sara back to town after getting knocked out by La Signora, a parallel to how a tengu (heavily implied to be a young Sara) carried a young Itto back to town after their duel and tumble down Byakko Plain. And because the two both use La Signora's Ashen Heart boss drops as ascension materials, it is also a point of interest for shippers to see the two tag team against the Harbinger, if she had not died in the aftermath of her confrontation against the Raiden Shogun.

Character Voicelines
"Tsk... I can't help but get a little irate when his name comes up. He kicked up a big fuss when I confiscated his Vision, by far the noisiest person... no, the noisiest oni I've ever encountered. He showed he was enough of a man to admit defeat, but the rematch he insisted upon... Tsk... To this day, I still don't want to talk about it. If you really must know, you can go and ask him yourself."

- Sara's voiceline "About: Arataki Itto"

"You know what, yeah, she beat me during the Vision Hunt Decree. I'm not ashamed to admit it! When you lose, you admit defeat, and when you screw up, you take it on the chin, like a man! And anyway, let's not forget which one of us won't agree to a rematch — her, the tengu warrior! It's just a sumo street fight, I mean, what's she so afraid of? If she keeps snubbing me, I'm gonna have to stop calling her Kujou Tengu and start calling her Kujou Chicken! Heh, we'll see what she thinks of that."

- Itto's voiceline "About: Kujou Sara"

Bulletin Board Banter
"Tengu of the Kujou Clan, hear me! You'll pay for taking away my Vision! Don't you forget about our duel!"

- Itto to Sara, on the Uyuu Restaurant Bulletin Board

- Arataki "The Supreme" Itto, on the Ritou Bulletin Board

"Bet you lost a fight and can't show your face outside anymore, eh? Hope you're not crying in some corner with your bald wings wrapped around you or anything!...Come on, don't worry about it! You win some you lose some, am I right?"

- Arataki "Burning Passion for Battle" Itto, on the Ritou Bulletin Board

"Kujou Tengu, I'm still in Ritou! Did you flee again? ...You must've fled in the night after hearing my name, eh? Hahaha, is my name scarier than the battlefield? That's fine, I'll wait for your return here at the harbor!...Don't you dare die on the battlefield, Kujou Tengu! You still owe me a duel!"

- Arataki "The Oni Sumo King" Itto, on the Ritou Harbor Bulletin Board

"If this is some kind of blessing before I set out to war, then I will accept it. You don't get yourself killed either, you idiotic Crimson Oni."

- Sara's response to Itto, on the Ritou Harbor Bulletin Board

"Ahahaha! Ever since I got my Vision back, I've been super motivated! Guess who's back? That's right, I'm back! C'mon, Kujou Tengu, I heard you went to hiding and had to flee all the way back there. I'm practically laughing myself silly over here, you know? Ahahahaha! I'll be waiting for you at the port just for an extra laugh, and don't forget about our duel!"

- Arataki "A Vision Returned" Itto, on the Ritou Harbor Bulletin Board

"Kujou Tengu! I think the entrance to Hanamizaka is a good spot for a sumo duel! Where are you?! Put all that military and governance stuff aside for a day and let's have a good match! Or did you leave your samurai honor on the battlefield where you dropped it?"

- Arataki "The Man" Itto, on the Hanamizaka Bulletin Board

"Kujou Tengu! I'm here on the Commercial Street, stop hiding and crawl out of whatever hole you're in and fight me fair and square! This one's for taking my Vision away, an eye for an eye!"

Miscellaneous
"Nice of you to join us, General Kujou. Are you here to make me beg for mercy, too?"

- Itto to Sara in his official character demo

"Oh, but, General. If you join the Arataki Gang now, I can show you what dreams are made of."

- Itto to Sara in his official character demo

"Regarding the various contests he has been in, there are two that still weigh on Itto's mind quite heavily. One of them is the rematch that he demanded of Kujou Sara, who defeated him and took his Vision as part of her duties in the Tenryou Commission. To this day, the Kujou has not agreed to the street corner sumo match, something that frustrates Itto to no end. The other incident happened many years ago when Itto was young. Then, he had gotten into an argument with a young tengu, the result of which was a sumo match in the Byakko Plain. Unexpectedly, the ensuing furor sent them both rolling down a mountain. In the end, it was the tengu who carried Itto, who could not walk after spraining his ankle, all the way home. Of course, the match went unsettled. Just his luck, Itto often thinks, that both such incidents had to do with tengu! Also, how on earth were these tengu all so strong despite looking so skinny?"

Trivia

 * Yang Menglu (Sara's CN voice actor) reposted an IttoSara edit on her Weibo.
 * Liu Zhaoku (Itto's CN voice actor) has also acknowledged the IttoSara edit by retweeting Menglu's post of it on his personal Weibo.
 * Itto, a five-star character was bested by Sara, a four-star character during their battle for his Vision.
 * Additionally, Sara's favorite number is five.
 * They both have non-human blood, with Itto having oni blood running through his veins, while Sara having that of a tengu's.
 * They are both also the last of their respective yokai species before Takuya's introduction as being a fellow oni.
 * A parallel between the two is how Itto proudly displays his oni heritage whereas Sara was peer pressured into hiding hers as a result of her father's tutelage.
 * In one of her Serenitea Pot voicelines, Sara tells the Traveler that a "Red Horned Lizard" would be a nice pet. Itto, notably, possesses red horns.
 * People who have lost their Visions are noted to lose their ambitions and become lost in life, but Itto instead declared a rematch with Sara and never stopped pursuing her for it even after his Vision was taken away.
 * Itto is slightly more childish in the Chinese version, calling Sara stinky tengu (臭天狗) and bastard tengu (混蛋天狗) in the Inazuma Commercial Street Bulletin Board and Ritou Harbor Bulletin Board respectively.
 * They both use Elegance Scrolls as well as La Signora's Ashen Heart from her weekly boss rewards to ascend their talent skills.
 * Both Itto and Sara grew up as orphans who were forced to learn how to take care of themselves as a result, becoming well known for their respective strengths at an early age. Thus, resulting to Itto becoming the founder and head of his clan, and for Sara to be taken in by her foster father from the Kujou Military before shortly being promoted to becoming their general.
 * Another similarity would be the fact that both were orphaned yokai who were taken in by human surrogate guardians. Granny Oni for Itto, and Kujou Takayuki for Sara.
 * Byakko Plain, the location where a young Itto had a sumo wrestling match with what's heavily implied to be a young Sara at the time, is the same location wherein the rival-lovers Iwakura and Teruyo fought their last battle from five hundred years prior to the events of the game.
 * Additionally, this is also shown to be the same place wherein the duel for Itto's Vision took place, as shown in Itto's official character demo.
 * Itto's line when he invites Sara to join the Arataki Gang, "I can show you what dreams are made of." can translate to "dreaming of one's future together" or "you will be seeing butterflies (if you join my gang)" when the word "dream" is used in this context in Korean, with "seeing butterflies" also meaning "to invite to eat ramen together". While in Japanese, "dream" when used in this context can mean "I can show you what ecstacy feels like." or "I can show you what it feels to be addicted."
 * Interesting enough, the official Chinese dub of Itto's demo has him tell Sara "I've yet to make you have sweet dreams." after inviting her to join the Arataki Gang.
 * In the second part of their Ritou Bulletin Board exchange, Itto asks if Sara "lost a fight and is now crying in some corner", followed by him saying he "has no time for her moping" and that she owed him a duel. While in the original Chinese dub, he instead says "I don't have the time to care about you!" written using "心思" (literally meaning "heart" and "good intentions") just after his poor attempt at comforting her.
 * In addition to the heavy implication of the pair being the descendants of Iwakura Doukei and Teruyo, Teruyo's line to Doukei, "I will never forget a single one of our duels in these past thirteen years," mirrors that of Itto and Sara's current situation of an indefinitely postponed rematch that follows the events of their initial battle for Itto's Vision.
 * During their thirteen years of sparring, Iwakura and Teruyo only ever fought ten times . This parallels how, when combined, Itto and Sara's first names ("One" from "Itto" and "Nine" from "Kujou") add up to the number ten.
 * One of the game's official Instagram ads has Sara being interviewed on her thoughts on Itto, with the caption being her voiceline about him in her character profile.
 * On February 01, 2022, the official Twitter account of HoYoLAB reposted fan artist Soc Nau's piece with IttoSara and Jeanluc on one of their teams.
