heya! i don't know what kind of limited chr. i can request but don't worry it's not too much! (i think so???) yandere big brother, well not an incest, but cuz we know they gonna be possesive. yandere big brother ciel, alois and kanato (from diabolik lover) with innoncent gn s/o cuz, why not~? they kind,naive and pretty much act like a saint? don't forget they really easily been manipulated due to their innoncent personality. headcannon?? pretty please? have a good day and night~!
So I'm guessing as like they're possessive of their younger sibling and never wanting their sibling to be in danger, so I'm going with that mentality for the characters!
Yandere Big Brothers with naïve, innocent, easily manipulated sibling (Ciel, Alois, and Kanato)
Ciel
Very much is making Sebastian watch you at all times if he can't
He has to know where you are at all times. He's not taking chances with his younger sibling being kidnapped or anything else.
Very much if you run away from home, Ciel is dragging you back and making sure that the servants watch you to make sure you don't even leave your room and have an escort to the bathroom and to be in there too.
He's constantly checking up on you. If you're not happy, he's doing everything with his power to make you happy.
If anyone looks at you the wrong way, he has Sebastian kill that person. No one will change your innocence.
Alois
Will have Claude on you a lot.
Big brother that does not give you space at all.
Very much threatens anyone who even talks to you. You're his precious little sibling and he wants you to just him.
He really doesn't care about your social life, you only need your big brother.
While he is violent to others, he isn't to you at all. You're precious. He doesn't want to harm a hair on you.
Kanato
Only he can manipulate you.
No one else can interact with you, only him. Other siblings may get stabbed by him if they talk to you.
Very much plays mind games so you're constantly caring for him and all your attention is on him.
If he sees you leaving, he will yell and scream at you. Mainly about how others will hurt you and take advantage of your naivety and innocence.
He wants hugs, a lot. He feels he's protecting you best too with the hugs.
