IttoSara

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

Canon
Itto's Vision was confiscated after he was defeated by Sara 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 by a masked lady.

In the Ritou Bulletin Board, Itto calls Sara "Kujou Tengu" and messages her on the bulletin board, trying 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 fled 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 alerts 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.

Quotes
"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 takee 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 Kujou Chicken! Heh, we'll see what she thinks of that."

- Itto's voiceline "About: Kujou Sara"

"Don't you dare die on the battlefield, Kujou Tengu! You still owe me a duel!"

- Itto to Sara

"You don't get yourself killed either, you idiotic Crimson Oni."

- Sara to Itto

Fanon
Fans have taken note of Sara's 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.

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, although only recently gaining attention, 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.
