[ platonic yandere! holy knight x saintess! reader ]
summary: no one had expected that the holy knight that everyone adores is a complete siscon.
rei's notes: remember this headcannon? they are from the same timeline and lore but different kingdom, hehe.
honestly speaking, platonic yandere! holy knight wasn't really aware about your identity in the first place.
but there was one thing that he was sure of. what is it? it was the fact that he hates his parents down to his core.
i mean, he was practically sold at the church just to pay off their debts. you actually expect him to love them and be thankful for what they did?
his stay at the church wasn't really good. he was treated as a slave. but when they realized that he has a talent for swordsmanship and mana- their attitude towards him had change 360°. now, after some convincing session with the archbishop- he was now a holy knight in training.
which was a good thing since it made his life easier. now, he doesn't have to deal with shitheads since they were way too scared to approach him after they saw him beating up another knight after they called him "orphan."
anyway, when he got a week of break. he decided to see what his shit of a parents was doing. just a glimpse, he convinced himself. but platonic yandere! holy knight knew that he might lose it once he saw those faces.
but still- he wanted to know how his parents were doing after they dump him on the church and made his life a living hell.
and that was how he saw you- a younger sister whom he never knew the existence of.
he never showed his face in front of you. he remained hiding behind the tree while he watched you play with your mother. watching how you smile brightly at them.
he expected himself to be envious. he expected himself to hate you. but no.
because- for the first time on his life. platonic yandere! holy knight had found something... cute.
whoah, whoah, whoah. what is this? no one had informed him that his parents can actually create a fucking adorable thing. wait- are you even their daughter in the first place.
but much to his dismay and happiness- base on the rumor that he heard in the town. you are indeed their daughter. you are actually related to him! yey!
your first official meeting with your brother was at the city. while you were happily buying some food, he casually gave the shopkeeper the money, paying your food while he took some for his own.
you were confused, which is really cute btw. but his face remained stoic while he chewed his skewers.
wanting to pay him back, you followed him around during his stay on his hometown. and during those time, he made sure that the two of you had a good time.
playing, eating, or simply walking next to one another. platonic yandere! holy knight treasured those moments.
but all good times came to an end when he came back to the church. that was the time he came back to his usual stoic and brooding self who never give a fuck to other people.
platonic yandere! holy knight is the smothering type. no one expected that because of his appearance but he really loves to spoil his darling a lot.
because that was his way to show to his darling that he cares. oh, by the way. just like your good ol' yandere- he is extremely protective. he just wanted you to have a normal life. that was why he was glad that his shitty parents seemed to treat you really well.
atleast, that was what he thought until he saw you at the church... what? at first he was confused, then next, he thought that it was a complete bullshit. why do they have a twelve year old- wait, nevermind. the adults inside this kingdom are trashes anyway.
at first, he thought that you were sold. but then, when he was informed that you were the new saintess. he had lost it.
okay, sure. he agrees that your existence is really pure and divine. but the thought of his baby sister getting involved in politics had made his skin crawl.
that was why he decided to be your personal knight by the time he became the captain of the temple's knights.
did he inform you about your true relationship with him? no, never. he rather die than to do so. even though the thought of you calling him "big brother" is tempting. your position as the saintess was dangerous enough.
he didn't want you to be in danger just because you are related to him. he was a shit, he knows that. and without any doubt, he had many enemies inside and outside the kingdom.
by the way. whenever you are out with him- this guy made sure to cover you and your face so much. to the point that you looked like a walking cloth.
he had to test your foods first before you were able to eat it. and the present from other people? rejected. what if they send you a bomb?
all in all, despite of his tendencies on being a helicopter parent. platonic yandere! holy knight is a great older brother who won't hesitate to kill for you or kill himself if you asked. just say the word and he'll give you anything you want.
but honestly, the most hilarious thing is the fact that you were not aware why the hell is he so overprotective and loyal to you. since he never told you that he is your older brother. so you think that all holy knights were as intense as him.
to add some nonsense detail, there were some times when platonic yandere! holy knight sent a letter to another knight from the luwelton empire (warren) everytime he don't know what kind of gift would you like.
the two of them met when the emperor of the said empire had visit the kingdom to meet the archbishop. and noticing the devotion that platonic yandere! holy knight had towards you. the two of them clicked since warren also love his younger sister a lot.
“ what do you think is better, sir warren? dress with frills or just food? ”
“ .... didn't know you are a fan of frills- pervert. ”
“ why? it's cute- wait, sir. this is for my sister. ”
“ haha, i guess food is a safer option? my sister almost killed me when i gave her a dress with a lot of frills. ”
