Higuchi has a boyfriend and Tachihara is going to find out who.
Notes: 👀 BSD x JJK, I wrote one AGES ago as well and since I am in a mood and rewatching JJK before S3 I offer thee some more Ichiyo Higuchi x Choso Kamo because tbh he's her type. (Fast Trust HERE)
It started when Higuchi was sent to Tokyo for a meeting. One the Black Lizard had only been made aware of when said meeting finished and they’d finally noticed that she had not been in the office at all that day.
Whatever had happened at the meeting must have been good considering the mood she had been in... and the subsequent attitude change towards Akutagawa that followed.
This was seven months ago and yet somehow the woman before him was a totally different person- well no she was still his badass Big Sis but she was more willing to snap at the Black Lizard when they fucked up now… and argued with Akutagawa when he was in the wrong which was honestly pretty cool to see when the Rashoumon user just stood there mouth agape in confusion.
Higuchi glanced down at her phone, the ghost of a smile on her lips as she taps out a reply before placing it back down on her desk. She goes back to work seeming just that bit happier than moments ago.
“What’s got you in high spirits Big Sis?” Tachihara asks as he hands her his recent mission report.
“Nothing much. What’s this report for?” She asks as she flicks through the papers.
“Warehouse mission Nakahara handed off to my team. International drug smuggling ring trying to store their contraband onto Port Mafia property.” He states. “We managed to scare them off and take the contraband. We’ve burned it all and gotten rid of every last piece.”
“Good. Thank you for the report I’ll go through it later.” Higuchi places it on top of her files which to him is a sign of importance.
Her phone screen lights up again, a text message blinking on the screen.
Choso Kamo 💕: Can’t wait to see you after work 💕💕
Who the hell was Choso? Why was there a heart next to their name? He tried to get a better look when he finally noticed her background picture… which last he’d seen was a nice scenery photo now its not. Definetly not that anymore.
He sees Higuchi on the screen with the brightest smile he’s ever seen as she leans into a tall man with loose dark hair and… a tattoo across the bridge of his nose? They’re in casual clothes, happy as can be and with the way he’s looking at her he can tell there’s a lot of affection in his eyes.
She lifts her phone, that smile widening just a bit more as she types a reply to the mysterious Choso. Tachihara glances away, hoping she didn’t catch him snooping.
“Yep, need me to do anything else Big Sis?”
“No that’s everything today Tachihara. Thank you for the report.”
He nods and walks off to his desk.
Holy shit he needs to tell Gin.
An hour later and Higuchi was out the door, her workday over and Tachihara chose the moment that door shut to shoot across the room and slam his hands onto Gin’s desk.
“Higuchi has a boyfriend.”
“What?” She raises a brow.
“I saw her phone when I gave my report to her an hour ago. She got a text from some guy named Choso and her lockscreen is a picture of her and a guy looking happy and loving.” He said in one breath.
Gin gave him her full attention at that.
“What did he look like and did the text have a full name?”
Out the corner of his eye he saw Akutagawa give them an annoyed look while he heard Hirotsu sigh.
“Black shoulder length hair, messy vibes, a black tattoo across the bridge of his nose- which confuses me, maybe he’s emo or goth or something I guess- real pale guy, looked pretty tall going by the picture and built, bro has muscles.” He replies, fingers tracing the shape of the tattoo. “Oh uh Choso Kamo and it had a heart next to it.”
She nods conspiratorially and begins typing away at her computer.
“What are you two doing?” Hirotsu walked over, looking like a disappointed dad more than anything.
“Higuchi has a boyfriend.” Tachihara states again.
“I heard that the first time. Why are you two acting odd?”
“Big Sis having a potential boyfriend is a big deal man! What if he’s a piece of shit, or a monster trying to make his way into the mafia via her? Also because I want to know how the hell someone got her to stop crushing on Akutagawa.” The Rashoumon user spat out his tea at the last bit. “And just in general it’s Big Sis and as her honorary brother I must vet this man.”
Tachihara places his hand over his chest like he was about to serve his country or something.
“Found him!” Gin clapped, turning her computer in their direction. “Choso Kamo, teacher at a private technical college in Tokyo.”
“She’s dating a… teacher?” Part of him felt totally underwhelmed at that information.
Gin scrolled through the file- for an assassin she would also make a pretty good spy with her tech skills.
“Doesn’t look like he’s been their long either. He’s twenty-four, six-foot, has a younger brother Yuji Itadori who attends the school. Teaches physical education.” She clicks on an additional link which opens a page to a teenager’s social media- assumedly the younger brother.
There’s the guy, dark hair, face tattoo sitting in a tank top playing a video game- assumedly losing to the pink haired kid beside him… who also has face tattoos. Is their whole family delinquents? What’s with the face tattoos? Is the school for troubled youth?
The muscles though, Tachihara could definitely tell the guy worked out, which probably made him a good PE teacher.
This was his Big Sis and if this guy they’ve never heard of is dating her he needs to investigate.
“Let’s follow her.” He says decidedly.
“I’m down.” Gin stands. “Ryu come along.”
“Why would I want to do that?”
“Uh because this is Higuchi we are talking about. You know you’re intrigued and annoyed she hasn’t paid you any attention recently.” She goads.
“I am not, this is idiotic.”
“Party pooper. I’m going to buy a puppy on the way home.”
“Don’t you dare.” He glares at her, Gin just smiles, her mask not even hiding her glee. “Fine.”
“You in old man?” He asks Hirotsu who just sighs again.
“You all need adult supervision so I suppose yes.”
They found her pretty fast, her car parked just down the street from her favourite café- what Tachihara pays attention sometimes. She’d changed from her work suit into a red long sleeve and jeans and her hair was now loose around her shoulders as she walked down the street towards who could only be Choso Kamo. His dark hair was messy and loose, the black mark on his face stark against his pale skin and he wore a grey shirt with the sleeves rolled up his forearms and jeans like Higuchi.
Casual. This was a casual date.
He still can’t believe she’s dating a P.E Teacher.
Choso’s arm wraps around her shoulders, pulling her in close as he leans down to kiss her.
Tachihara held back the urge to gag.
The couple then went inside and the group of stalkers decided to move closer, finding a covered spot that looked directly into the window seat they chose- convenient for them they supposed.
They looked so happy, he’s never seen her smile the way she was now and a little part of Tachihara knew he’d been a total asshole to her at times and any smile she did have often dropped, a tiny bit but he always noticed. Man he was such a jerk.
“Gross.” Akutagawa said, nose scrunched up as he glared at the couple.
Gin broke first, giggling at her brother, which made Tachihara laugh as well. Akutagawa was blunt sure but for some reason him saying gross was the funniest shit.
The date seemed pretty simple, just coffee, some cake and their hands being held across the small table. Their smiles never dropped even when they stood up to pay and leave the café.
“Is the date over yet?” Akutagawa grumbled.
“No shut up.” Gin chimed in as the couple walks across the street towards a park hand in hand where a market was being held. They buy crepes and continue to walk around, pointing at stalls and chatting quietly.
The group follows carefully, casually. Just in case they are spotted for any reason they act like they’re just conveniently also at the market… even though Akutagawa looks like he’d rather die and Hirotsu looks more and more like a tired dad as the afternoon goes on.
Higuchi and Choso make their way to a particularly romantic spot, origami strung along trees like fairy lights as they looked over the park- the mafioso’s hiding behind a tree (which definitely looked comical to passerby’s).
“It really does just seem like a date.” The Rashoumon user said finally, obviously bored.
“Obviously man but come on isn’t it a little interesting? She’d mentioned nothing to us at all- yes I know she doesn’t have to but we are her closest coworkers, practically friends. She’s pretty much my sister at this point. We must vet this so called Choso Kamo, PE teacher from a random Tokyo private school to see his motives.”
“I agree with Tachihara. We are in the mafia we don’t just date civs.” Gin crosses her arms, her cheeks tinging just a tad. “Granted I don’t date colleagues so I get her I do.”
“You date?” Akutagawa’s head whipped towards Gin who just looks away, whistling casually.
“It is probably high time we head home, I feel as though we are very much intruding on them.” Hirotsu stated, he looked tired of having to be the adult to the trio of troublemakers- well duo plus Akutagawa but still.
“Oh you are.” They jumped.
Tachihara’s soul absolutely jumped with him, nearly leaving his body as Higuchi practically materialised behind them, her date in tow.
He laughs, the nervous kind that goes on a touch too long.
“Oh hey Big Sis funny seeing you here.” He scratches the back of his head.
Her arms are crossed, mouth pressed in a firm line as she stared down at him like a disappointed older sister.
“You and Gin make sense but you two?”
“Who knows what rabble you have stuck yourself with, for the sake of the team I obviously had to make sure you didn’t do anything stupid.” Akutagawa coughed, looking away.
The real answer was that Gin threatened him with buying a puppy knowing how much he hates dogs but the man would never admit that.
“They needed adult supervision.” Hirotsu added which only made Higuchi sigh more.
“These are the coworkers I take it?” Choso asked, smirking while he did- well it looked more like he was trying to not laugh at their expense.
Oh she was mad. Very mad.
“Hello everyone, my name is Choso Kamo.” He greets them, “I’m Ichiyo’s boyfriend.”
Higuchi’s cheeks tinge for a moment but the annoyance is still clear on her face.
“We know, we searched your file.” Gin said without remorse, the group look to her and she shrugs. “What we did? We were concerned.”
“I appreciate that you’re concerned for Ichiyo but I promise I have all the best intentions with her.”
“I also appreciate the concern but am incredibly annoyed that you followed us all afternoon.”
“Of course I knew you idiot.” She sighs. “I saw the gears turning the second you saw my phone screen at lunch and heard you yell Higuchi has a boyfriend before I had even actually left the office.”
Tachihara can feel the heat creeping up his neck.
“And not to mention how shit all of you are at hiding Choso saw you before we even went inside the café.”
“That is true.” He laughs, wrapping his arm over her shoulders. “Don’t be too mad this is like when my younger brother and his friends followed us around the school for an hour.”
Well at least that confirms that he was actually a teacher- to the group at least.
“They are teenagers who barely get to experience being their own age these idiots are my coworkers from the literal Mafia.”
“Big Sis- okay I am sorry but I was just worried.” Tachihara scratches the back of his head again. “What if the guy was using you or he was just a douchebag?”
Her arms drop as she leans into the tall dark haired man.
“Thank you for looking out for me Tachihara. But you should have just asked, I would have told you.”
“Yes. You’re like my little brother of course I would have. I didn’t say anything because being in a relationship has no relation to our line of work.”
“Oh yeah I guess that makes total sense.” He laughs. “Guess we overstepped a little.”
“Just a touch.” Her nose scrunched up, amused now. “But since you’re all here I guess you can get to know the man who stole my heart.”
“What an honour.” Choso laughed, kissing her forehead. “Ask you questions I will be completely transparent with you all.”
“Well I won’t pass up the opportunity!” Tachihara grinned, Gin clapped her hands together in agreement, Akutagawa just sighed while Hirotsu put his hand forward.
“Good to meet you young man my name is Ryuro Hirotsu.”
“You as well sir.” He shakes his hand.
Tachihara still can’t believe his Big Sis is dating a teacher.
