You ask and you shall receive, top 5 ship headcanon of Rizumo that you absolutely love and will fight anyone for it
This is going to be a LONG HC of development. XD
For one, Rin’s crush on Shiemi is obvious, that is something any person knows. And I will always think Izumo will be insecure about that, even when they do start dating. After all, Izumo has been the one pushing the idea on Shiemi that she does have feelings for Rin, so I do think Izumo ignores her own feelings and possible crush on Rin. Even the moment she told Shiemi when Rin was sent to the past, her expression was very solemn. So honestly, even when or if Rin grew feelings for her, she will always be skeptical and push it down and reject him a lot. She’s not playing second best for anyone.
Izumo spoils Kuro with treats and cat toys, she shops for him a lot, surprising Rin himself with the stuff she brings. She makes the excuse of just ending up with them, but that girl actually saves and does what she can to even have a moment with the feline. It’s gotten to the point Rin even offers to pay her back from all the stuff she gets for him, which she always declines and says it’s no pressure at all. Even so, Rin appreciates her kindness, wondering why she fights him so much when offering to cat sit or pet him.
Izumo tutors Rin, this was evident a lot in the ao no exorcist novels. I feel Rin has a learning disability or at least ADHD, so it’s hard for him to focus a lot. Izumo makes it easier for him of the notes she writes and breaks them down for him to understand. He loves how neat and good of a teacher she is, even complimenting how he appreciates her being so patient with him since Yukio usually isn’t. Even though it’s hard for Rin to concentrate, it’s harder for Izumo when he compliments her to no end about it. She also gets on Yukio and even Bon at times for calling Rin an idiot, or dumbass, since having so much time tutoring him, she learns firsthand how smart he really is.
Also, random note, I headcanon if Rin and Yukio did not makeup during the latest chapters, Izumo was ready to throw hands at the younger sibling for making Rin cry. (Those two really have a crying thing between them)
Also, Rin doesn’t know why, but deep down, he really hates when Izumo cries. Seeing a girl like her who’s always so strong and contains so much inside, it’s hard for him to see her like that without trying to make her feel better in some way.
Izumo likes wearing Rin’s shirts, loving his scent on them, despite her always making the excuse that they stink and needs to learn how to wash them.
They both share and trade mangas they both are fans of.
If together, I headcanon think they would have 4 kids. I have a lot of reasons and feelings about this, and I do think it reverts to the fact how much family IS important to these two. They both lost so much, and both have gone through trials when it comes to their parents who died saving them, and the love they have for their siblings. So having a big family is something they BOTH need, especially Izumo treasuring her kids like her mother did before her, despite them being the children of Satan. Even when people are against the existence of her children, Izumo adores them and does not treasure them any less for it. Also, I have their kids formed to be the 4 horsemen of the Apocolypse, so there’s a whole rabbit hole there for ya XD.
Rin and Izumo also tag along together when visiting their parents’ gravesites, needing someone who can support them who understands the pain and reason why they are even alive today to even be where they are (FIGHT ME) LOL XD.
There’s more, but this is already more than 5 xD.
Thank you @i-can-see-the-stars for this ask!!! ;w;
