Hayaryuu

Hayaryuu is the slash ship between Kamitani Hayato and Kashima Ryuuichi from the School Babysitters fandom.

Canon
When Kashima met Hayato for the first time, he thought that he was "that type of person" because he punched his little brother on the head, but Kamitani then tells Kashima that he has to go to see his little brother because he felt alone without him.

When Kotarou got sick, Kashima immediately ran right to Hayato and asked him if he could guide him to the nearest hospital. Kamitani didn't think twice, and left his little brother in care of his mother and helped Kashima, giving the right direction to the hospital. The next day, Kashima thanks Kamitani for helping him and then went to class, where he noticed that Hayato was there too. While he was introducing himself, he looked nervous, but after he saw Kamitani, he was calm and then gave a little smile to him and then finished his introduction.

Anime moments
When Kashima was heading to his classroom, he felt uncomfortable because the people surrounding him were giving him a "stare" and he thought that it was him that he was getting many weird stares. When he asks Kamitani if he had something in his face, he asked in response what was he doing with the kids tagging along behind him. Ryuuichi panicked and apologized to the people surrounding him and then asked Kamitani if he could help him taking the kids back to the Daycare center, which Kamitani accepts.

The next day when the kids with Usaida and Kashima were going to an excursion, Kamitani passed right where they were and then he asked Kashima if he could leave his little brother in his care, which Ryuuichi accepts and then he asked Kamitani if he forgived his little brother already (because he punched him again), he said that he didn't really liked him and then his little brother hears what he said and ran to another place of the excursion with Kotarou. Before Kamitani left the place, he told his little brother not to cause problems to Kashima and everybody else, showing that Kamitani cares about Kashima first than another people. After the excursion, both guys are showed up walking together back to their homes while carrying their brothers. When Kashima asks to Kamitani that if he was worried about his little brother, he said that his mother found him in the baseball team and then smacked him telling that he needed to be with his little brother. Kashima smiles while he said "Even so, i'm glad. He was lonely without you", and Kamitani's little brother, which it was asleep, he said that he loves Kamitani and then he blushed a little while he replied; "Idiot, i don't really hate you either". Kashima laughs and said that Kamitani can blush too, which Kamitani complains and tells Kashima that his little brother (Kotarou) likes him too much, and we can see Ryuuichi complaining about that.

When they were in the P.E class, which it was cold out there, Kashima asked Kamitani if he was cold, which Kamitani said in a sarcastically tone: "No, i'm so cold, i could die", showing no expression about having cold, which Kashima laughs a little nervously. Later, when Takuma and Kazuma were calling their father, we can see Kashima and Kamitani holding them while they were right next to each other.

The next episode, Ryuuichi it's showed with an invitational poster in his hand for the Gakuen Club. When Usaida asked Ryuuichi and the kids if they wanted to check out the other clubs,  they agree and Kamitani's little brother suggests that they will see the baseball club too (which Kamitani was) and Usaida agrees at that. When they finish checking out the other clubs, they went directly to the Baseball club, which Ryuuichi notices that he was there and then Taka (Kamitani's little brother), tries to call his brother, and when Kamitani notices that, he just ignore him and then he cried out loud. Kamitani punches his brother when he went directly where Ryuuichi and everybody else were and Kashima apologized saying that it wasn't his intention for interrupting him while he was in his practiced. Hayato said that it was okay, that his club was weak anyways. After everybody left the Baseball club, Kamitani tells to Taka not to disturb Kashima which Taka yells and says that he doesn't bother him. When Kashima was distracted by looking another club thinking that they were having fun his little brother notices what happened and when Kashima asks Kotarou if he wanted to go with him to stick the poster, he rejects the offer and Kashima shocked because he didn't expect that answer. When Kashima arrived to where he was going to stick up the poster, he kneeled down thinking that maybe his brother didn't want him around. When he was in his thoughts, someone hits his head with a paper and when he lift his head, he saw Kamitani with his brother in his arms and then he asks if he could join the Gakuen Club. Kashima was a little confused and he said that if he wanted to join the Baseball club too, which Kamitani says that if they were talking about that, he would accept, but they were talking about the Gakuen Club. Hayato gives Ryuuichi the membership to the Gakuen Club and then he said apart that [Kotaro] invited him to the club. When Kamitani hands Kotarou to Kashima, he explained that Kotarou was dragging him by the pants and then Usaida was interpreting the situation. He also said that Kashima looked miserable and Kotarou thought that he helped him in that way (dragging Hayato to Kashima). After that, Usaida made matching aprons to both guys with their names.

In the Inui's incident, Kashima asks Kamitani what does he think about the Adultery, Kamitani asks in response that if that wasn't something for the people involved to decide. Kashima complains that they're talking about an affair about someone who has a child already, which Kamitani only says; "At the end of the day, it's their problem, isn't it?", Kashima stays in silent after he said that to him, pondering about his past when a similar event happened in his childhood.

When Kirin and Taka were fighting about if witches and heroes were real or not, Kamitani was about to say neither of them were real, Kashima shuts him with his hand covering Kamitani's mouth saying that he don't have to destroy the children's imagination. Later, Kamitani tells Kashima that he have to tell them already that both witches and heroes aren't real but Kashima says that he don't want to destroy the child's dreams. Also, he says to Kamitani that he might believed in that kind of stuff when he was young, or maybe not. "Oh yeah, i tried to practice a launch that disappears, but someday i will make it, so that's different".

When Ryuuichi forgots his lunch, Kamitani asks him what did happen that he was a little concerned. He said that he forgot his lunch in the Daycare center, and told him not to speak while his mouth was full. While Ushimaru offered her food to him, he rejected and then Usokawa and his classmates gave him mountains of food like their "feelings" toward Kashima. Kamitani pats Ryuuichi's shoulder while saying: "Aren't you lucky to have classmates like that?" which Ryuuichi replies to the "praise" with: "Kamitani...". Meanwhile, when Kotarou was giving Kashima his lunch, his classmates worried about Kashima's full belly, and when one of them was about to complain in high voice, Kamitani shuts him with a bread he had somewhere, showing that Kamitani doesn't want anyone to hurt either Kashima and Kotarou feelings. Next, when they arrived to their class, Kamitani asks Kashima why is he walking around with an apron, which Kashima notices and asked Kamitani why didn't he tell him if he noticed. Also, Kamitani adds that Kashima's butt was full of stickers. Saying that he's surprised that he couldn't notice while the kids were adding stickers in his butt, Kashima blushes really bad and he complains that he could tell him about those things earlier.

When Kashima received a love letter, Kamitani checked out first to affirm if the letter was just a prank or not, showing that Kamitani worries about Kashima feelings and that he would check out his actions that could hurt him or not. Later, when Kashima thought that he losted Kotarou, Kamitani appears with Kotarou in his side saying that he went into someone's yard for getting a lemon. After Kashima rejected the girl who sended him the love letter, Kamitani asks if he was sure, that he seemed excited about it, while Kashima says that he wanted to keep his brother as the primary priority.

In another episode, we can see Kamitani calling Ryuuichi asking if he was free that day because they were going to a festival with their brothers, which Kashima says yes and then both guys passed their phones to their brothers so they could invite each other personally. When they arrived, Kamitani asked Kashima why was him and his brother wearing formal clothes (yukatas) which Kashima says that Saikawa and Obaa-san prepared it for them.

There were a lot of moments of them and their brothers in this episode like; they went to buy cotton candy to their brothers, catch golden fishes and more things. When Taka loses his sword, Kashima proposed to find it, which Hayato almost disagrees. Before doing something, Kamitani told Kashima that he should go back to enjoy the festival, because Taka was causing many problems, but Kashima says that even if he isn't in the Babysitting Club, he would search the sword. "We're friends, right?". Kashima said that unconsciously and he was wondering if he was the only one who thought that they were friends, which Kamitani replies; "You're really incredible. If he wasn't my brother, i wouldn't even take care of such a troublesome brat". Kashima got surprised at his answer, but at the same time, his comment made cry Taka, after that, Kashima tells Hayato to stop making him cry. After that, they went in a search for Taka's sword in all the festival, even if doing that would be hard and would cause many problems. When they were about to give up, Kamitani told Taka that he had to give up. Taka hesitated but Kamitani said that in exchange, they would bring him to the Rope Game and told him that he has to bear with it. Ryuuichi it's showed to be moved by Kamitani's words and then Hayato said that he needed to thank Kashima for helping him finding his sword, that he would be given up if Kashima didn't suggest them to find it. After they found it in the Rope Game, the guy in that game apologized and give in exchange a Coin bank with a PS3 style to them.

In the beach scene, it shows Kamitani and Kashima talking in the water. Kashima told him that it wasn't his first time going to the beach with his brother, saying that Kotarou was still a baby so he doesn't remember it. "But he wasn't scared of the water back then. Kotarou... i guess he just doesn't trust me". Right after he said that, Kamitani hits Kashima's head while he complains and asks him if he does always hit his brother that hard, but Kamitani replies that he only hit him about a half as hard. "The reason Kotarou wasn't afraid then, is because he was just a baby who understood even less than he does now. Don't say such stupid crap". After he said that, Kashima felt okay in that moment, saying that Kamitani was right.

When Kashima saw Taka with a bloated face, he quickly asked Shizuka (Kamitani's mother) what happened to him, she shows him a ball with a "Poo-like" scribble in. She said that it was Hayato's treasure he held for a long time. "You're not telling me he got angry and hit Taka really hard this time!?"- Kashima asked in panic.

Surprisingly, Shizuka said that Kamitani ignored Taka after that. Also, she asked Kashima if he could check out Kamitani, which Kashima accepts. After Kashima convinced Kamitani to talk with him, he wanted him to apologize Taka for what he did, but obviously Kamitani rejects saying if Kashima was referring him as a childish person and that he should stop being angry already and forgive him. "Kotarou broken a lot of my things too, i understand the feeling of really not even wanting to look at his face"- Kashima added. Kamitani seems interested on that and he asks if something similar happened to him. Kashima explains everything that Kotarou did like Kotarou breaking a Matchstick model of Osaka Kashima spended 2 weeks for that, sribbled the homework Kashima finished without sleeping all the night, also when Kotarou stole Kashima's phone and throwed it to the toilet. "Especially with the phone, it had messages from my parents, i'll never get any more of those"- Kashima explained. Kamitani pat Kashima's shoulder while saying "Cheer up". Hayato said that in his case, it was the opposite, explaining that he really didn't care about the stuff but the intentions of Taka. He also adds that if he tell him to apologize, Taka yells and become unreasonable, but in the end, he had to deal with it. After school, when Taka and Kamitani apologized, Kamitani asks Kashima if he will be in the daycarem which one says yeah and then Hayato adds that they will be playing baseball with the kids and with Taka too, Kashima complains a little.

In the parents meeting, Usaida made suits for the kids and for Ryuuichi too. When Kashima wore the suit and Yayoi scare him, he fell and the kids rolled him to the entry, which Kamitani soon appears right there and wonders what was that big cob doing blocking the way. Kashima replies that the big cob was him and asked Kamitani if he could help him to get up which Kamitani accepts.

In other episode, it shows that Kamitani punches Taka in the head by any reason while Kashima asks why his first reaction was always the violence, which one says that he hits people who don't do what he says, then his mother punches him in the head too. When Shizuka asks everyone if they wanted to see chick eggs hatching, everyone agree with happiness while Hayato apologizes to Kashima that his mother got the kids excited, which one turns to Kamitani with shinning eyes. Kashima got nervously altered by his reaction and explains to Kamitani that he can't help but wants the chicks to follow him around in a line while Kamitani replies that the kids do that all the time too, which disappoints Kashima saying that that might be enough too.

After Usokawa invited his friends also Kashima and Kamitani, Kashima arrived first and then Kamitani. Kashima asked Kamitani what was that bite mark in his cheek, Hayato told him that his brother was screamming "Bring me [with you to the cinema]!" and he bite him, which made Kamitani angry and then hit Taka's head just for leave the place later. Kamitani also asked if Kotarou didn't cry, which Kashima answers no and adds that he was quiet when he left the Morinomiya's residence.

In Chirstmas Day, when Kamitani was about to say to Taka that Santa wasn't real, Kashima covered Kamitani's mouth with his hand for second time saying that if he said that, he would destroy Taka's dreams.

Also, when Kashima asks Kamitani where he was going, he said that he was going to "skip" class. After we notice from Ryuuichi that actually, Kamitani went to the chairwoman's office to ask Obaa-san that if she could buy a new phone for Kashima, which one accepts and in the end of the episode, we can see Obaa-san giving Ryuuichi the phone Kamitani asked for buying it.

Manga
There are many moments about this ship throughout the manga and a missing part to the anime (some chapters will be showed up). Some of these parts are:

While they were going to take a photo in the Parents meeting, Kashima asks Kamitani where his father was, Kamitani says that he is divorced and it's a person that Kashima already knew, which made Kashima confuse at that answer.

Next day, when Kamitani and Kashima were going to their classroom, Kashima said that he thinks he's forcing a secret out of Kamitani, while he says that it was okay, that he didn't plan to keeping it from him. When Kamitani retires from the teacher's lounge (where his father, his chemistry teacher, Hebihara Taizo was), Kashima notices that he had a "really hurt expression" he never saw before, and when he entered to the teacher's lounge, he gives instead of a reflection, he gave Hebihara a summary about the stories of Kamitani and his brother in the Daycare center, showing how much Kashima cares about Kamitani's feelings and also his family. "Kamitani-kun who always looks calm, had shown a really hurt expression which i've never seen before. My family... may be differ from Kamitani-kun's, but this kind of thing is definitely wrong!!. No matter how hard we try, we'll never be able to meet with our parents again. Why is that,  even though they're so close to each other, he has such a cold face when he's talking to Kamitani-kun? He doesn't even visit Taka-kun. I don't get it." Next day, after Hebihara gave back both guys report cards, Kashima noticed that in his report the letter and the photo were gone. Kamitani after asks Kashima with an angry tone about the photo and the letter that Hebihara left on his report letter, which makes Kashima panic about it, but in the deepest on his heart, he knew that Kamitani was thankful about that, even if he didn't show it physically in that moment.

In chapter 35, with the Inui's Incident, when he fell in love with "Inomata" (that was Ryuuichi disguised as her), Ryuuichi wanted to clear the misunderstanding by telling him the truth being dressed as Inomata. Yayoi also asked Kamitani if he could help Kashima by acting as "her" boy. When Inui arrived to the scene, Kamitani started talking: "This is my woman, you better give up", while Ryuuichi (as "Inomata") was panicking and saying in his mind that Kamitani was being too stiff with the lines. However in the end, Ryuuichi failed to clear up the misunderstanding.

While Kashima worried about that Kamitani didn't answer his call, he noticed  thanks to Kousuke that he thought he could hear Taka's voice in the background while calling Kamitani "You shall never be able to step into the house again!!". He inmediately conclude that Kamitani was freezing while being stuck outside of his house, and then Kashima ran to Kamitani's house to see if he was okay. When he arrived, his theory was right and then rescued Hayato from his "death".

While the kids were writting their wishes for the Tanabata, Kashima asks Kamitani to write a wish too while Kamitani declines, but later, he changes his mind and put his wish in a paper then sticked it in the Tanabata. When the wish was coming "true", Kamitani complains that he doesn't believe that it was coming true just by hanging his wish to the Tanabata. Kashima seems to not understanding  it and Kamitani says that he wasn't listening at all and added that Hayato didn't believe even for a second that his wish came true just for the Tanabata's blessing, that he wanted to go as far as he can with the team he haves. When he was about to leave the Daycare center, Kashima said that he was going to leave it as it is. That everyone was saying that luck is also part of Kamitani's skills and he wanted him to do his best, hoping that it would cheer him up with his words.

When Kashima, Kotarou, and Saikawa went to a grocery shop, they noticed that Kamitani was there too with his brother. Saikawa invites Kamitani and his brother to Morinomiya's residence where Ryuuichi was staying, after dinning right there, Kashima lend Kamitani a room where he can stay and after that, Kamitani spent the night in Ryuuichi's house.

When both guys went to the New Year festival, Yayoi asked both guys if they could dress like Mikos, because she would be busy which Kashima accepts and Kamitani said that he couldn't say anything fine from now, which Kashima apologizes to him for making a decision without asking Kamitani.

In the moment that Kashima defended Yuki getting him by a snowball which Hayato throwed, Kamitani apologized and added that the pose Ryuuichi made for protecting Yuki was really suitable for a outfielder, which Kashima said that he don't have to change the topic but he thank Kamitani about the praising.

When Taka ran out of his house, Kamitani tried to call Kashima unsuccessfully, then some minutes later, Kashima checks out his phone and noticed that he had a losted call from Kamitani and Ryuuichi calls him again. When he picked up the call, Kamitani said that there wasn't time now, but Kashima wanted an explanation about his situation. After he tells him about what was happening, Kashima offers to help and right before Kamitani would say anything, Kashima cut the call. After Hebihara found Taka and brought him to Hayato and Shitzuka, Kashima said for hiself: "The situation of Kamitani's family is still pretty complicated, but maybe it's not one that is as difficult as i thought" showing how Kashima worries that bad for Kamitani and his family.

In Ryuuichi's birthday, Kotarou told everyone to say Happy birthday to Kashima while they were hugging him, between those people it was Kamitani included too. After bringing the cake, Kamitani heard Kotarou explanation and, despite he was a bit confused, he did what Kotarou said and hugged tightly Kashima while saying "Happy Birthday Kashima." while Kashima said while blushing "Thank you, Kamitani.." .

Fanon
A common joke it's that fans love to say about Kotarou being the wingman of this ship because his several moments Kotarou made Kashima and Kamitani closer, and they joke that in the Festival scene they went to a "double date" with their brothers. Also, they joke that Usaida might ship them too because of several moments he did almost the same thing as Kotarou. This ship can be shipped alongside with Inomaru, also, this ship have a rival too: Inuryuu, which one doesn't have a big popularity, but it's a really known ship in the fandom.

On AO3, it's the most written ship in the School Babysitters fandom as well as the most written ship for both characters.
