Platonic Yandere Kento Nanami x Adoptive Daughter!Reader
This was the Request of @yukiotacon i hope You like it!
Warnings: Yandere behavior, Overprotectiveness, isolation, past trauma (HAIBARA), unhealthy relationship, UNHEALTY MINDSET, some persecution, angry Nanami is a scary Nanami. I think that's all.
At first Nanami never thought he would be a father, with his line of work and how lethal it is, he did not believe he could even get married to start a family.
Although of course, that changed completely when you lived in his life.
You were the youngest daughter of a family that had been a victim of the curses, and a special girl at that, because you were able to see the curses before apparently, but your family had discarded them as imaginary friends of their infant daughter.
Thanks to this, they could not foresee the imminent danger and it cost them their lives.
When Nanami found you, all alone, crying for someone to help you, but still with innocence on your face... it awakened something in him.
(Haibara, you remind him a lot of Haibara, someone whose life and innocence were taken from him, he can't let them do the same to you)
Kento decided that he would take care of you, although to be honest, he knew there was something wrong with him at the time he decided.
but he honestly didn't care at that point.
That's how you ended up as his daughter. I tried to make you have a normal life, away from the curses, to make you forget about your bad experience, but some marks remained forever...
Nanami has mostly overprotective tendencies and is somewhat strict, but at the same time she is very aware that what she feels is WRONG.
So I have long insisted on having your life, yes, but away from the world of Sorcery.
He will tell you HORRIBLE anecdotes and stories of co-workers who died at work, the horrors of curses, everything to keep you away from that world.
He himself usually eliminates curses that appear near his house, so he will hardly teach you anything at first.
It is only when you start your high school years that you insist more on the topic of learning how to better deal with curses because, well, schools are full of them.
(Nanami begins to regret not having taught you at home but it's too late)
If you insist enough, you will finally get him to teach you the basics of cursed energy and thus be able to kill curses little by little.
honestly Nanami is a nice Platonic Yandere to have. in this special case at least.
As long as you don't do anything related to the world of Wizardry, he's almost like a normal father. Just a little paranoid and protective, but hey, what father of daughters isn't?
When Nanami is an office worker, this side of him is more noticeable, because although he is miserable with his job, he is more than happy to see you have a normal life as a NORMAL teenager. Coming home from work and finding yourself either arriving or leaving school is very rewarding.
He feels like he found a reason to live.
Even if Nanami is more manageable at this time, he is no less lethal to anyone who even remotely poses a threat to you.
Did you mention someone who followed you at school? no more.
Is a classmate teasing you at school and the teachers do nothing? Kento will talk to that person...
The same goes for people he considers a "bad influence" yup, he's that kind of father. It requires knowing your friends (or at least, their parents) to know if it is safe to leave you with them. If they don't pass his standards, you won't see them or hang out with them again.
He just don't want to lose you...
For this reason, he is quite undecided about whether to tell you about his return to the world of Jujutsu.
He KNOWS you're interested in Jujutsu even after all, but he doesn't want you to go down this hole with him.
You would eventually find out, he reasons, and if he were to die on the job, you DESERVE to know why after all.
whether he tells you or you find out, you find out and Nanami doubles down on his overprotective tendencies by 200%.
Your current year of high school is homemade, why? because Nanami no longer trusts that high-grade curses cannot appear where you study and you cannot defend yourself.
stay home where it is safe.
I can see him even installing (without telling you) a baby monitor somewhere in the house to make sure you're there all the time.
If Gojo finds out about you, Nanami would be soooo screwed. Gojo wouldn't stop pestering him to tell him things about you, but at some point Nanami explodes and threatens him VERY SERIOUSLY to rip his throat out if he breathes another word about you.
It startled Gojo a little to be honest.
I mean, he was used to annoying Nanami all the time, but seeing how he changed so drastically when he brought up a specific topic related to you...it was even terrifying.
what topic was it? Letting you go on quests as a Sorceress.
Nanami thought it was just a joke from Gojo (as always) but in reality the thing was... different.
You had gone for Gojo to give you some training secretly from Nanami when you saw that he clearly wouldn't give it to you.
and Gojo simply accepted because he thought it would be fun to see Nanami's reaction when he found out.
Gojo didn't think Nanami was AS bad as you made him out to be with the overprotectiveness, you were a teenager after all.
but now...he took it more seriously.
Satoru wanted to know if Nanami would be okay in a "hypothetical" case because even if it seemed funny at first, he didn't think that with everything Nanami had been through he shouldn't take his opinion into consideration.
Although in the end he decided that the best thing would be to send you for more experience and (hopefully) give Nanami a lesson in your capabilities.
NOW, when Gojo sends you on your missions, you are ecstatic, finally some action! Finally something different from your normal, monotonous life! It was great!
The hardest part was altering the monitor that you KNEW your father had left at home and fixing it before he arrived. A part of you tried not to feel bad about all this, but on the other hand, who in their right mind puts a MONITOR on their TEENAGE DAUGHTER?? You had valid points.
although it didn't last long...
Nanami knew there was something wrong with you and in general several things were happening simultaneously with that.
Nanami randomly lost control of the monitor she had left at home and only recovered the image even hours later.
and he could feel that every time you were with more... attitude? more challenging.
He HAD to know what was causing this rebellious phase in you that he KNEW it would get worse if he didn't stop it, maybe some guy? He will kill him,a bad influence friend? He will get rid of it, but he has to know.
and when he does that is when he sees you come out of a successful mission.
tired, with some scratches, with your energy damned at FULL and when both of you exchange glances....
And run, and run and run...
What else should you do? You weren't going to tell him this way! You didn't want to face it.
Besides, the dark look your father had before he realized you had seen him was...dark to say the least. You never thought you'd see your father like this.
although you also didn't expect to see him come after you with a new level of anger.
It looked like a wild animal going after you.
You tried to use the advice that Gojo had given you, but you found yourself overshadowed by your desperation, he was much faster than you...
You tried to take him near civilians, thinking that he wouldn't try anything with them around, but you were scared when you saw him take out his tool.
Was he REALLY going to use it!?? With so many people around!? It's leaving you without options.
You finally decided to go somewhere further away from the people for their safety, but at some point you lost Nanami from sight. no no no no where the hell did he go??
The only thing you remember before falling unconscious was thinking about how you left your teacher waiting.
and now here you are back, at home, with your "father" on another "normal" day.
The house now looked like a military fort when you woke up, with an anklet on it.
despite all the turbidity of the matter. You just wanted to know something from your father. The WHY of all this, what makes it worth it?
His answer sounded both crazy and made a lot of sense, at the same time that you understood something...
that he just wanted to protect you at all costs, he has already lost so many people in his life for that reason, he refuses to lose you too...
Shares, reblogs and comments are very welcome!
Thanks for the Request ❤️❤️❤️
