Alright so the requester and I have both watched the anime and are reading the manga (at least I know I am but that's not super important, requester knows the stuff that was left out of the anime for some dumb reasons like wtf guys this shit was fucking important) but it's been three months since I got this request and there hasn't been much of a backstory as to why Teru is the way he is (which is why I've been waiting to write this) so I'm gonna make something up with the information that has been provided over the past three months but that being said-

WARNING: MANGA SPOILERS !!!

"(Y/n)-san!" Hanako shouts the moment she passed by the girls bathroom. "Come here a moment!"

She sighs and takes in a deep breath before walking in. "Yes?"

"Now now, that's not what you call me~" He chuckles as Nene mops the floor in misery.

She glares at him, refusing to call him by the awful name he demands to be called. "Hey now I am the one who made you a half spirt, couldn't show me some gratitude?!" Hanako pouts but gives in. "I need you to go on a top secret mission." He says, now sitting on the window seal.

"Oh?" She replies, leaning against the wall to stay out of Nene's way. "And what might that be?"

He chuckles when Kou walks in, "your first task is to get him out of here." Hanako grins, pointing at one of the Minamoto siblings.

Kou sighs, holds his hands up, and walks out of the bathroom. 

"Why did you do that?" Nene asks.

"Because this mission has to be kept from everyone, including you Yashiro." Hanako replies.

"Oh..." She mumbles and exists the bathroom as well.

"Won't they just try to eavesdrop on us?" I ask.

"Yeah but that's okay," Hanako replies and walks over to me, getting really close to my face. He whispers in my ear, "I need you to track Teru Minamoto. I have a feeling he is up to something. Get close to him and find out what he's doing."

"Huh?" (Y/n) mumbles, "and what do you think he's up too?"

"You remember when he was trying to kill me, right? Pinned me down and Kou had to stop him before he killed me?"

"I mean yeah but what does that have to do with anything? He hates supernaturals like exorcists are supposed too."

"But he had to train and learn all that experience somehow, right? So you're job is to find out what is really happening when he's not at school." Hanako smirks, "or in other words..." His face moves into a mocking expression and points his finger at (Y/n), who's clearly not amused. "You must become his stalker!"

----

"This is so stupid." (Y/n) mumbles to herself, as she walks home with Kou. "Thanks for understanding though."

He smiles brightly, "of course! It may be strange but you have a reason, and if I can help you out then I want to."

(Y/n)'s face softens, "anyway do you have idea when your brother will be home?"

He nods, "he won't be out long. Maybe in about half and hour. Just wait here," they stop at the corner of the street. "He won't be able to see you when he passes you by."

She nods and plops next to a trash can, "He wouldn't dare look here..." She then looks up at You, "thank you again." They both wave goodbye, leaving (Y/n) questioning all of her life choices.

Sure enough Teru was passing by half an hour later, just as the sun had finally set. He walked by without even look at where (Y/n) had been hiding at. He just walked into his house and that was that.

(Y/n) came out of her hiding spot and moved to the opposite of the street, leaning up against a street lamp. What she was planning, even she didn't know. After all that stupid brat in the hat won't shut up if she comes back without any information. The best thing, and the most sort of legal thing, she could do was wait and see if anything interesting happens.

After all Teru is too smart for this to be easy. He would know something was up if she just started talking to him out of the blue. It wasn't like she could gain his trust in a matter of two days, it would take a life time and then some to be able to achieve that.

Three hours pass and (Y/n) is just about ready to give up and go home when Teru walks out of the front door, dressed in all black, weapon in hand. "Good thing I waited so long..." She mumbles and starts following him.

The streets were dead that this time of night. Everyone was asleep in their homes or knew better than to go outside alone at this time of night. Just because it's dangerous, does that mean he has to bring his sword with him?

They walk down a few more streets before running into what looked like a mop of supernaturals. (Y/n) knew supernaturals where a thing and all but she never imagined they would gather all in one place like this, in the middle of the street no less.

Teru remained calm has he unsheathed his sword, stabbing any supernatural that came his way. He was quickly surrounded making (Y/n) jump into the fight. "Never thought you would get into a situation like this." She said as she pulls out her knife from behind her back. She always made suer to keep one with her. Even if it means walking around with a knife shoved in the loops on her pants.

"What are you doing here?" Teru replies, watching as she cut up one of the supernaturals. "I thought you would be the type to not kill anything."

"So sorry I'm not Nene." She retorts back only to be met with a chuckle as a reply.

"That knife, is that yours?" He questions, staring a second too long. (Y/n) turned around to see a supernatural Teru's head about to get ripped off. She takes the knife in both hands, stabbing it into its forehead before pulling it back out.

"How about we chit chat later, or were you going to take care of that one yourself?" She replies, getting a few more hits on some of the smaller ones, Teru backing her up and finishing the blew.

"I was going to show off but have it your way." He laughs slightly.

"My hero." (Y/n) mocks and they continue to fight without saying a word.

About ten minutes go by and the supernaturals disappeared without a trace. "So this is what our lovely president does in his free time." (Y/n) teases, putting her knife away.

Teru smiles with his eyes closed, "well what else would I be doing?" He opens his eyes but keep the same smile on his face, "I am an exorcist after all." He sheathes his sword before his facial expression changed from a care free too serious.

"Yeah you are but it looks like you could use some help." (Y/n) smirks, "if only I wasn't here-"

"I would have been fine thank you." He tries to cut her off but she picks up where she left off.

"I wonder what would have happened to you." She smiles at him, "maybe we should team up."

He chuckles, "maybe we should. Though I should tell you I don't talk very much."

"Oh I doubt that." (Y/n) bites back.

"About secrets I mean. Why else would you be following me here if not to gain my trust? You're not very good at hiding your intentions." He laughs.

"Who said I was trying to hide what I was doing? Clearly I couldn't hide it since I had to follow you. On the other hand I couldn't tell you straight up either. So making things obvious was the best choice." She explains, "don't you agree?"

Teru smirks, "fine then. I guess we are a team now." He holds out his hand for her to shake, "nice working with you. Can't wait until next time."

(Y/n) stood there with a blank look on her face, "you being serious right now?"

"Yep." He replies, still holding out his hand. "Whatever it is your up to, I can stop you no matter what. But you are a good fighter, definitely need more experience, but still good. Therefore I want you to help me out some nights. In exchange for you helping me I'll answer whatever questions you have, honestly."

Once again (Y/n) stood there with a blank look on her face as she contemplated the deal. If she came back without any information, brat in the hat won't shut up for at least and hour about it. She sighs and shakes his hand, "fine but only up until you graduate.  After that we're done."

He smiles, "it's a deal then."

Yeah don't ask me wtf this was cause I don't even know. I've been trying to come up with ideas for this one shot for about three months now and haven't gotten anything. So I let very tired and sleep deprived me just write down whatever came to my mind and just went "have no fucking clue what to do but not everything I write can be a winner"

No explanation this time, the request was "half spirt like Akane (the guy in the glasses), trying to gain his (Teru's) trust" so yeah I don't know how to take that and thus this was born. There isn't much information about Teru that doesn't boil down to "yeah no he hates supernaturals" and, to me at least, "I'm a shady bitch lol"

But anyway-

I hope you got some enjoyment out of it. I'm going to sleep now. Also please let me know if you see anything that looks weird or wrong (writing wise) and I will fix it.

LOVE YOU GUYS
