Let me reiterate. This is a one-shot. Unless I am suddenly struck with a lightning bolt of inspiration (or many people ask... i cave into peer pressure too easily... damn my desire to please others...) I will not be 'continuing' this. More info about "possible continuations" in the a/n below.
"Let's summon a demon!" Tsuna's stupid roommate suggested eagerly.
"Let's not do that," Tsuna replied flatly, warily eying the Ominous Black Book in his roommate's hands. Why was he friends with his roommate again? Oh right, because his roommate was one of the only people in the school who didn't look at Tsuna with disdain.
Sometimes, Tsuna felt that the nice company his roommate occasionally provided really wasn't worth the trouble that came with it.
For one, there was the time his roommate accidentally opened up a portal to the realm of hungry ghosts right in their bathroom, causing them to have to use the communal showers for two months until they figured out how to close the portal. Also, not all the ghosts that came out of the portal went back to their realm and that was… unfortunate.
Two particular ghosts with irritating laughs enjoyed dropping into their apartment every now and then, 'kufufu'ing and 'nufufu'ing whenever they could.
And then there was poltergeist attached to the piano his roommate bought. They knew that the piano was cursed and yet bought it anyway, causing the poltergeist attached to the piano to blow up random things in their apartment until Tsuna forcibly sat him down and talked through whatever problems the poltergeist had.
The poltergeist now blew up the people who looked down at Tsuna instead. Along with the two ghosts that really needed to go back to the hungry ghost realm now, thanks.
Another was the time they accidentally entered an abandoned shrine and brought back an annoying white kitsune who kept stealing their marshmallows, of all things.
Tsuna could write an entire book on his misadventures with his horrible, horrible roommate who probably had a mental disorder that disallowed them to feel fear, but that wasn't the point. The point was that Tsuna really should know better now not to indulge in his roommate's dangerous impulses.
That did not explain why he was allowing his roommate to prick his finger and allow a drop of his blood to land in the middle of the summoning circle his roommate had drawn out of cheap chalk.
"Why can't you use your own blood?" Tsuna whined as he sucked on his bleeding finger to stem the flow of blood. He didn't really want to drip blood all over the floor; the stains from the Dead Deer incident still mocked him in his dreams. Blood was really hard to get out of flooring.
The roommate sighed. "That's because demons have annoying conditions for summoning them. I've already done the do, so I'm ineligible for a blood sacrifice."
"How did you know that I've never had sex before?" Tsuna asked, more amused than perturbed that his roommate had actually thought about his sex life.
"Are you kidding me?" his roommate snorted as they flipped through the Ominous Black Book. "You obviously aren't interested in those sort of things. I don't need a brain to see that." They stopped on a page and tapped it with the cheap chalk. "Wanna summon this one?"
"No. I don't want to summon anything," Tsuna replied around the finger in his mouth.
"Okay, this one it is," his roommate said before they started speaking rapidly in another language. A wind started to blow in the room although the windows were closed and the doors shut. Tsuna sighed and braced himself.
The lights flickered once, twice, and then the room plunged into darkness. The candles around the summoning circles flared to life one by one, slowly illuminating the room and the being standing in the middle of the summoning circle.
Black was the first thing the two saw. Black shoes, black pants, black dress shirt, black eyes, black hair, black hat. Tsuna's roommate whistled appreciatively once they could see the being's face.
"Man, they're hot. Then again, that's expected of an incubus, yeah?" they commented. Tsuna rolled his eyes and stepped forward to greet the being. Non-human or not, the incubus was still a guest in his house and he was brought up to treat all guests with the respect they deserved. (Unless they were kufufuing and nufufuing uninvited intruders. Those he would chase away with a broom.)
"Hello and welcome to our home. Sorry about summoning you so suddenly; my idiot roommate thought it would be fun to die via demon," Tsuna said with his default polite smile. The incubus slowly dragged his eyes up and down Tsuna's body, a sinfully attractive smirk stretching across his features.
"You're the one who summoned me?" he asked. Tsuna shrugged.
"Technically, it was my roommate. But they used my blood so maybe? I'm not too sure about the whole mechanics behind demon summoning, really," Tsuna replied.
"You're a bit calm about this whole demon thing," the incubus noted. Tsuna sighed tiredly.
"Compared to the other shit I've went through, meeting you is one of the least panic-inducing thing I've done." The incubus narrowed his eyes, treating Tsuna's words as a challenge. Tsuna felt a sliver of foreboding thrum through him and he quickly stepped away from the incubus.
"Don't worry, as long as the candles are lit, the incubus can't get out of the summon circle!" Tsuna's roommate chirped. The incubus smirked at that.
The candles died out. Almost immediately after, Tsuna felt something warm press up behind him. Hot breath fanned against his ear as the incubus whispered into his ear.
"How shall I… service you, Tsunayoshi?" the incubus asked. Tsuna stiffened in uncomfort, quickly taking a step forward and away from the presence behind him.
"By not doing that?" Tsuna suggested hopefully, prompting a chuckle from the incubus.
"I can make all your wildest fantasies come true-"
"In exchange for something," Tsuna butted in. "There's always a catch with deals like this."
"I just need sustenance," the incubus said. Tsuna rolled his eyes.
"And you'll just take more and more until you suck me completely dry and I die of exhaustion, right?"
The lights flickered back on and Tsuna saw the incubus standing in front of him with a raised eyebrow. "Have you summoned a demon before?" he asked.
"Not really," Tsuna admitted honestly. "But the terms and conditions aren't really hard to figure out." Tsuna paused as he thought over the incubus' previous words. "All of my wildest fantasies, huh?"
The incubus' eyes gleamed. "Do you have something in mind?" he purred as he stepped closer. Automatically, Tsuna stepped away.
"Can you help me finish all my assignments before their due date?" Tsuna asked eagerly. The incubus narrowed his eyes.
"Are you kidding me?" he demanded. Tsuna sighed in disappointment.
"I thought so," he muttered. In a louder tone of voice, he said to the incubus, "Then I'm not interested, sorry." He smiled apologetically as he turned away to clean up the summoning circle. If the chalk stayed on the floor for too long, it would seep into the floorboards and become a bigger pain to clean.
"Could you please get the mop and a bucket of water?" Tsuna asked his roommate. Almost immediately after the words left his mouth, there was a mop in his hands and a bucket next to his feet. He turned to look at the incubus.
"I can clean up the mess for you," the incubus stated. Tsuna considered the incubus' words. On one hand, he would have to provide the incubus with… sustenance. On the other hand, it was nearing three a.m. and he had a morning class later on in the day. Finally, he just shrugged. The incubus was just going to clean the mess off the floor; Tsuna probably didn't have to give him much in return.
Just to be sure, he asked. "What do I have to give you in return?"
"Just a kiss," the incubus answered. Tsuna hummed. That was fine.
"Alright then, I accept your terms," Tsuna said. The incubus snapped his hands and the summoning circle, candles and all, were gone. There was a blur of black and Tsuna was pressed up against the wall, the incubus' mouth on his.
Tsuna may not have had sex before, but he certainly knew how to kiss. Not very well, he'd admit, but good enough to get by during spin the bottle or any other party games he was subjected to.
The kiss lasted for a minute before they broke apart. Tsuna was panting from the lack of air, face red, while the incubus seemed unruffled. The only sign that he was affected was the ethereal, almost unholy, gleam in his eyes.
Quickly composing himself, Tsuna slid out from between the wall and the incubus. "Thanks for helping me clean up. You're free to go do whatever you want to do now," Tsuna said. Instead of immediately disappearing back to wherever he had come from, like Tsuna expected him to, the incubus just stared at Tsuna with an unnerving intensity.
"Uh-"
"You said you wanted me to help you finish all your assignments?" the incubus asked. Tsuna laughed uncomfortably.
"Well…"
"Alright then, I can tutor you."
"What's the price?" Tsuna immediately asked. The incubus smirked.
"A kiss for every day I help you," the incubus answered. Tsuna hesitated.
"And nothing more?"
"Not unless you want more," the incubus said. Tsuna pondered over the deal. The incubus seemed intelligent enough, and something told Tsuna that he would most definitely be able to help Tsuna with his assignments.
"Alright then," Tsuna agreed. Immediately, the incubus grinned, baring his teeth, and Tsuna felt regret.
The incubus was standing right in front of Tsuna now, trailing a finger down Tsuna's cheek in a mockery of a lover's touch. "My name's Reborn. Remember it," the incubus whispered into Tsuna's ear, and then he was gone.
Tsuna would reiterate this: Regret. Absolute regret.
"Where did you get the Ominous Black Book from, anyway?" Tsuna asked his roommate.
"From Uncle Kawahira of course," they answered. Tsuna resisted the urge to facepalm. Of course they would have gotten it from their creepy uncle. There probably wasn't anyone else in this world who would be able to procure such a thing, anyway.
"Oh right, I think you should be careful," Tsuna's roommate said suddenly. Tsuna was immediately on alert. His roommate wasn't wary of many things.
"Why?"
"Well, you probably didn't see it because you were busy having your mouth devoured, but the incubus… Well, he seemed like he was drunk off you or something. That kiss you gave him… it probably provided him with lots of power. It'll be likely that he would want more from you, and will go through any means necessary to trick or tempt you into giving him more."
Tsuna groaned at his roommate's words. Great, just great.
Once more, Tsuna repeated himself: I regret everything.
Full title (given to me by my younger brother, the best brother in the world): when you get bad friends and got to go to hell (with style)
Roommate is a random oc that's there to progress plot and create meeting opportunities. That's because Tsuna's isn't stupid/foolish enough to go summon a demon for fun. alternative27angel on tumblr said that the roommate could be Longchamp, though, and now I cannot unsee. Thanks haha.
You can guess the cameos in this fic.
I like supernatural stuff. I am also a garbage can. (My headcanons for tsuna shine clearly in this fic aha)
Should I continue with more? idk. I won't be writing only about Reborn if I do, though. (Originally, I wanted to write all arcobaleno but i was lazy. also, people are probably ooc)
