Can I request Reigen crushing on older sister of the kageyama brothers?
I can see mob supporting their relationship but ritsu? absolutely nope!😭
Reigen Arataka has a crush on Mob's sister!reader
you're an older sister of Ritsu and Shigeo and you're quite older than both of them because you're already an adult
you live alone but you often visit your parents and brothers
on one of those days you visited them you talked to Ritsu
he told you about Shigeo's suspicious part-time job and an adult who's using Shigeo's powers
of course, Ritsu made it sound worse on purpose to make you worry and do something
and you, as responsible and protective older sister, decided to deal with it on your own
you found the office Ritsu told you about, 'Spirits and Such Consultations'
'yeah, definitely sounds like the organization for frauds', you thought
you entered the office and a blonde man greeted you
'welcome! do you have some problem with spirits? i bet you do. but no worries because i, the greatest psychic of the 21st century Reigen Arataka, can definitely help you with that', he sounded pretty confident and polite
you looked around without saying anything yet just to explore the office. 'is it where Shigeo works?', you thought
meanwhile, Reigen thought, 'she's so beautiful. i have to ask her number after whatever she's here for'
you cross your arms and look back at Reigen with the most serious expression
'let me get it straight. do you know Kageyama Shigeo?', your voice is really intimidating and Reigen flinches
'yeah, Mob, of course. he's my protege, i teach him how to use his powers. and who are... you?', he tries to sound brave but he's terrified
'i'm his older sister and i don't really like that my little brother, who is in the middle school, has a part-time job! especially, at the place like this. so, you have about 10 minutes to convince me that you won't cause him any troubles or Shigeo won't come here ever again.'
you were dead serious and Reigen understood it
good for him, convincing was one of the best things he was good at
'okay, Kageyama-san, calm down. let's talk, i'll tell you everything', he speaks calmly with confidence
he comes closer to you, puts his hands on your shoulder and leads you to the chair in front of his desk
you roll your eyes but you sit down, arms still crossed
'first of all, Mob works here only because he wants to. i don't make him and, of course, i don't use him. i'm a psychic who's strong enough to deal with everything myself', he says it so confidently you almost want to believe it
'and secondly, Mob is young but very powerful. of course, he needs someone to look after him. and considering that i haven't heard of you before... you're not always around him? i care about him as much as you do, believe me', his voice is softer. you're actually about to fall for it. he knew how to melt the heart of a caring sister
'so, you actually do have psychic powers? could you-', you didn't finish the sentence
Mob entered the office. he was back from school
'shinshou. y/n-chan. what are you doing here?', he sounds confused
'nice timing, Mob! your sister was worried about the fact you work here. tell her that everything's fine', Reigen said
'you were... worried? but how did you know?'
'Ritsu told me', you said shortly
and then Shigeo explained that Reigen is actually a really good teacher, that he is really powerful so he can't even see weak spirits (that was unnecessary) and that he gave him really good advice
you sighed. Mob didn't seem to be intimidated or used. he actually kinda enjoyed it... this job...
'okay... but if he ever hurts you...', you turn your menacing gaze to Reigen, 'i will destroy him'
'he won't. i promise', Mob said it sincerely
you felt calmer and then left
'hey, Mob... is your sister single?', Reigen asked as soon as you closed the door behind you
'i don't know. yes, i guess. why?'
later in the evening Ritsu came up to you
'hey, y/n. so, you visited that office i've told you about?', he asked
'yeah. it's fine i guess. i don't fully trust Reigen but i think he's kind to Shigeo', you said calmly
he went to Shigeo to ask him about it
'so, you told y/n not to worry about it?'
'yes. she shouldn't. everything's fine', Mob said
'and did Reigen say you something?'
'he asked me if she was single. i don't know why'
Ritsu freezed. his expression changed.
'no way...', his face was as upset as if someone's just died
few days later Reigen invited you to his office again
he told you he would prove that his service actually works
'i'm not interested', you'd say
'i'll give you a discount! no. i'll do it for free! please, i really want to show you that i'm really responsible to look after Mob!'
and you eventually agreed
sitting in front of him again while he's talking
Mob was also there. maybe as a moral support (but for who exactly?)
'okay, even from here i can sense it', Reigen tried to sound serious
'sense what?', you asked sarcastically
'everyone has problems...'
'and you have... love problems'
'i have- what?', you asked
'so, i'm right. let me guess, you don't have a boyfriend?', he spoke like a professional
'no, i don't but it doesn't mean i have problems', you sounded offended
'of course i know it's hard for a beautiful girl to talk about this topic. but i can sense something else!'
'a man who destined for you by fate is near. you just need to look carefully not to lose your chance', he proclaimed it confidently, it was even easy to believe. the hint was obvious
'are you a psychic or a fortune-teller? i'm leaving', you stood up and was actually walking towards the door
'wait, Kageyama-san! there's-', the door slams behind you, 'don't... lose your chance', the last part sounded desparate but you didn't hear it already
meanwhile, Mob was sitting there thinking, 'i wonder who's the man that destined for my sister? i'll ask Ritsu about it later'
Ritsu was terrified when he heard it
i tried so hard not to make it too long but I MADE IT TOO LONG. sorry! i loved your idea SO much, i want to write the whole FANFICTION. i don't think i'm able to do that... but thanks for such wonderful request!
