๐ป// I wanted to drop a quick note here before you dive into the headcanon to talk about a stylistic choice Iโve made for this piece. For the sacrifice bride, youโll notice that Iโve opted to use "you" (second-person pronouns) throughout the narrative rather than the traditional "s/o" or "Y/N" placeholders.I know everyone has their preferences when it comes to reader-insert formats, but I personally find that using "you" allows for a much more seamless and immersive flow. To me, "s/o" can sometimes feel a bit like a speed bump in the middle of a sentence, whereas "you" pulls you directly into the bride's shoes, making the stakes and the atmosphere feel that much more intimate and urgent.

Ruki would sense the massive shift in Kou's energy immediately. He doesn't know the specifics of your connection yet, but he reads it instantly: you are a deep wound.
Ruki will not allow this to break his household's delicate dynamic. He will take you aside, away from Kou, to extract the truth with ice-cold precision. He wants every detail. Why did you laugh? Who were you with? How did you see him?
Once he knows, his treatment of you becomes purely utilitarian. You are no longer just a source of Eve's blood; you are a psychological weapon he can use to control or test Kou.
He will treat you with an air of superior disgust. He will deliberately place you in situations where you must rely on the very person you mocked, just to see the power dynamic shift.
He will control every interaction you have with Kou, not for your sake, but to prevent Kou from doing something "messy" and breaking a rule. He will become incredibly strict about your movements, essentially making you a prisoner within a cell.
Rukiโs specialty. He will make you feel like your very existence is a burden and an embarrassment to his family. Every time Kou is upset, Ruki will blame you, saying your arrival is the source of all their current friction. He will make you feel like the worst type of trash.
He will crush that independence by demonstrating his total power over your life. He might, for example, deliberately break a rule in your presence just to show that your moral standing doesn't matter; his reality is the only one that counts.
He doesn't bite for pleasure; he bites to weaken you. He'll drain you until you can't stand, just to watch you crawl on the floor like he thinks you deserve.
He'll lock you in a dark room for days "to reflect" if you show even a spark of independence. He needs you broken and silent.
For Kou, you are the ultimate test of his "give and take" worldview. You gave him laughter (and therefore, pain and humiliation), so now he must take everything from you.
When he first sees you, his expression is terrifying a dead, blank idol smile that is colder than any glare. Then, it turns into a predatory grin. "Ah... my little butterfly. I remember you. You used to have such a loud laugh."
He will treat your presence as a game of torture. He will use your past to justify every sadistic impulse. "You liked watching me suffer, didn't you? Let's see if your laugh sounds the same when you are on the floor."
Kou will constantly use his "Evil Eye" on you. He doesn't even need to ask. He can feel your heartbeat, read your fear, and sense your shame. He will use this to find the exact thing you are most ashamed of from your past and weaponize it.
If he catches you lying about how you felt back then, he will punish you with a deep bite and leave a mark.
If he finds you doing something nice or being independent, it triggers him. He might destroy something you made or deliberately make you beg for something simple. "You think you're better than us now? Then why are you asking me to feed you?"
He is the most physically abusive because he wants "payback." He'll strike your face or pull your hair specifically because you used those eyes to mock him and that mouth to laugh.
One second he's "playfully" hugging you, the next he's choking you against a wall because his Magic Eye saw a "haughty" thought in your head.
Heโll drink from you until you pass out, then wake you up with a slap just to do it again. "You liked watching me bleed? Now itโs your turn."
If you try to do anything for yourself, heโll sabotage it or break your belongings. He wants you to have nothing but him so you can never feel "better" than him again.
He'll beat you himself, then tell you heโs "saving" you from what Yuma would do to you. It's a sick cycle of pain and fake comfort.
Yuma is a protector. When he sees Kouโs reaction, his immediate focus is on protecting his brother. He doesn't care about the specifics; he knows you are a threat to Kou's peace of mind, and that is enough for him.
When he finally learns why Kou is reacting this way, Yumaโs reaction is straightforward, raw fury. Unlike Ruki or Kou, who work in nuances, Yuma would physically corner you. Heโd grab you by the throat or throw you against a wall.
His treatment would be aggressive and primal. He would use his immense strength to physically dominate and intimidate you.
He might make you do menial, degrading tasks in the garden, just to remind you of who has the power.
He might overstep boundaries to "protect" you from your own stupidity. If he thinks you are about to do something that might upset Kou, he will lock you in your room. His "protection" is about control and prevention.
He'll force you into back-breaking labor in the sun without water. If you collapse, he'll kick you and tell you to quit being "high and mighty."
He bottles his rage toward your past self and then explodes over something tiny like a smudge on a plate resulting in him trashing your room or physically intimidating you into a corner.
He'll make you eat off the floor or stay in the dirt, mocking your "aristocratic" human past while reminding you that you're just a "pig" to them now.
If you show any mental resilience, he sees it as a threat. He'll use physical pain to break your spirit until you're sobbing and begging for his "mercy."
When he first sees Kou's reaction, he immediately mirrors his brother's pain. He understands humiliation; itโs what defined his existence.
He understands humiliation; itโs what defined his existence. He will want to "help" Kou by taking your "pain" away from him.
When he understands the context, he is shocked but also fascinated. He sees you as a monster, but a very valuable one. "You... you can cause such wonderful... pain, Eve..? You...are a... powerful... being."
His treatment of you would be a twisted blend of obsession and torment. He won't try to make you laugh anymore. Instead, he will try to "gift" you the pain that you were once content to just witness.
He will cut you and himself, telling you, "This is what you loved, right? Feel it. Become a part of it."
If you try to be independent, he'll hurt himself and you to force a connection. He'll make sure you're too physically broken to ever think about leaving his side.
He'll corner you with his collection of knives, speaking softly while he carves reminders of your "sin" into your skin.
