Reincarnated Exorcist

Rin pulled the sword from its sheath. There was no way they were going to let Satan drag them and their father down. Even if it meant becoming a dem…what the flying fuck? Mephisto??!! They're related to Mephisto?!!! That—know what, they didn’t have time to think about this. Rin took the now flaming sword and plunged it straight through the Gehenna gate.

“Rin, you’re…ok,” Their father coughed out.

“Dad—dad! NONONO, you’re ok, it’s going to be ok.” They cried, grabbing their father. How could they have broken his heart like that? He was more their father than anyone else. Granted, they didn’t have much to go on when it came to comparing fathers. Still, they didn’t deserve to die.

“I’m glad I got to rais—” His blood-covered hand fell away from their cheek, and they snapped.

Rin gripped their dad close to their chest, screaming in agony. They couldn’t lose him Yukio couldn’t lose him. A dark emerald glow surrounded the two of them as Rin called upon Death. They still had one more life they could pick to save.

“You wish to save him?” Death asked

“Please, it’s my fault he’s dying, please,” Rin begged; even if Death owed them life, they could still deny the favor if it interfered with the strings of fate.

“He will be in a coma, and ultimately it will be up to him when he wakes after a certain time.” Death explained, if Rin were to save him, he would become one of their underlings. Only after his agreement, of course. Hence the coma.

“I don’t care, whatever it takes, just…please.” They begged, tears streaming down their eyes. Death merely nodded before releasing their grasp on the man's soul, allowing it to return to his body. Their boss had already granted permission.

*At the hospital*

“Yukio, why didn’t you tell me you were training to be an exorcist?” Rin questioned their younger brother shocking him.

“How did you—”

“Wasn't hard to figure out after watching dad take out all those demons. Explains why you always seemed to be staring at thin air too.” They shrugged, glancing out the window.

“Dad…wanted to keep you out of it as long as possible.” Yukio summarized.

“Yeah? Look how that turned out. He should’ve just given me up, the—” Yukio slapped their cheek hard, glaring at them.

“Don’t you dare! Dad loves you. He risked everything just to keep us safe. He would be even more heartbroken if he heard you talk to yourself like that.” Yukio seethed at their older sibling.

“I—I know it’s just…I caused this, I caused him to get possessed by Satan, now he’s in a comma holding on to his last strings.” Rin sobbed, holding their arms tightly as they felt the guilt wrap around them.

Yukio looked at his twin in contemplation; how could anyone ever see them as a threat? Sure, Rin was rough around the edges, but they were also kind, hard-working and their smile was brighter than the sun sometimes.

“Rin, the only one to blame is Satan. You reacted as well as anyone else could have in your situation. All we can do now is pray dad’ll wake up.” Yukio squeezed their arms in comfort.

“When’d you get to be so smart?” They wiped away at their tears. Honestly, if they’d had someone like Yukio in their previous life…maybe things might’ve gone differently then.

“About the same time you got overly emotional,” Yukio smirked.

“Ass”

“Bitch”

“Four—eyes.”

“Hothead”

The twins looked at each other before bursting into wet laughter. When was the last time they hung out like this? Rin couldn’t remember, and that was sad. Maybe they could get him to join them on their live streams or one of their videos.

“I’m gonna go get us something to eat, anything particular you’d like,” Yukio asked his sibling, wiping away their tear-stained face. Guess it was a good thing they had waterproof make—up.

“Spicy Tempura!” Rin shouted in excitement while Yukio shook his head in amusement. Rin always did enjoy spicy foods when they were down.

“Alright, then I’ll be back shortly. Don’t do anything too crazy.”

Rin watched Yukio leave before they pulled their phone out. Dad had said to call the number on the phone if something were to happen to him. They were almost certain it was Mephisto, which could be a good thing and a bad thing. Good thing because it meant they might be able to prank them. Bad thing if Mephisto figured out who they were in their past life, then, well, life would get a lot more complicated but maybe a lot more fun.

The chance to prank the stupid clown was far too tempting, so they called the number.

“Hello, this is principal Faustus speaking. Who is this.” Mephisto asked after the first ring.

“Uh, hi, It’s Rin Oku—” Rin dropped the phone in shock as Mephisto and a group of exorcists popped in front of them. Ok, they knew he was a space and time demon but fuck if that wasn’t quick.

“Hmmm, It would seem you’ve awoken your demonic heritage. Pity.” Mephisto mused as he looked Rin up and down.

“I take it that means you’re not going to help me?” Rin asked, staring into their older siblings' eyes.

“Rin!” Yukio shouted, almost dropping their food.

“Chill Yukio, I know what I’m doing,” Rin shouted at their brother, who stopped and stared at their sibling. When he saw the hidden glint in their eyes, he calmed down immediately. He knew that glint. It was I’m putting together a rather subtle plot that’s bound to shake things up while benefiting the both of them.

“Well, seems you’re slightly more intelligent than reports stated. I’ll make this easy then. You can either let us kill you here, quick and painless. Or you kill us and make your escape.” Mephisto grinned down at his younger sibling, frowning when he noticed her eyes were painted. She was much too young for make—up.

“Nah, there’s a third option,” Rin smirked at the clown, making him take a step back in surprise.

“Oh? Do tell?”

“Wouldn’t it be much more interesting to have the child of Satan under your thumb? After all, blue fire can burn even demons. Besides, I really wanna kick his ass for what he did to dad.” Rin mused, smiling up at their older brother, who returned the grin.

“Haha, you actually think you can? You know what fine; I’ll grant your request but answer me this, how’d you know about the properties of your fire?” Mephisto asked his sister.

“I’d like to know that as well,” Yukio asked.

“Maybe don’t leave your books out where someone can read them, also, get better locks,” Rin answered.

“What! But those were high-grade locks!!! How’d you break through them.” Yukio asked; he knew his sibling was good at lock picking, but damn.

“That…is a secret.” They said, placing a finger over their lips, smirking.

“Please stop doing that. It reminds me too much of that boyfriend you had about a year ago.” Yukio groaned.

“Boyfriend? Wha—“Rin cut themselves off as they remembered a boy around their age with rust-colored eyes, long black hair with…raven.feathers.braided in. Fuck they dated Sebastian. God fucking dammit. They thought they left him behind in the previous universe.

“Oh, that boyfriend. Imma guess he was a demon, and that’s why you chased him off?” Rin asked, holding back their anger.

“Well…that wasn’t the only reason, but yes,” Yukio answered, shaking slightly at the sudden glare both Rin and Mephisto sported.

“And you didn’t tell me because?” They both shouted before looking back at the other.

“We didn’t think it was important.” Yukio tried to appease the two.

“That’s it no Sashimi for a month,” Rin growled.

“And no missions.” Mephisto snapped.

“Wah, but you can’t do that,” Yukio whined, begging the two demons on his knees.

“Seeing as how I’m the only one who can cook, yes, I can.” Rin snapped

“Come along, little sister, let’s leave our poor brother to his sorrow while we get the enrollment papers filled out,” Mephisto stated cooly as he went to guide Rin, who flinched back from him.

“Shit, We told you Rin’s genderfluid asshole.” Yukio curses, jumping to his feet, ready to punch a dick.

Mephisto blinked stupidly at the pair of twins before pulling his phone out and calling his human secretary.

“Did there happen to be a report from Paladin Fujimoto about Rin Ok—You didn’t think to bring this to my attention? I see, pack up your things and leave—I mean you’re fired—actually I can my academy doesn’t discriminate that includes people chosen genders.” Honestly, he was a demon. Sure he preferred the male form, but demons didn’t really care about genders.

“Apologies, It appears I hired a homophobic secretary; she’ll be gone by the time I return. In the meantime, what are your preferred pronouns?” Mephisto grinned at their sibling; they were still too young to wear makeup regardless of gender.

“They/them, I tend to wear bracelets to signify what gender I am. Black is nonbinary, emerald is male, red is female.” Rin explained to the other Demon.

“Good, next question, aren’t you a bit young to be wearing makeup?” Mephisto questioned.

“Huh? Oh! This was supposed to be for a video I planned on filming later. I normally don’t wear makeup makes my face itchy. Most I’ll wear is maybe some mascara and a light coat of lip gloss. The only time it’s more is when I’m shooting a video that involves cosplay or a character I created.” Rin explained while shrugging as they walked off with Mephisto. Too young, pfft looks like she had to contend with overprotective brothers again…who were also demons. Then again, the Weasly twins might as well have been demons.

“What videos do you create?” Mephisto blinked in shock; Shiro had said she’d taken up creating videos as a way to generate funds for them, the church, and a few charities. Still, he didn’t realize it went this far.

“All kinds, some of them AU’s of a series I like, Some are cooking videos, Some are let’s plays. I wear a mask when I’m not in cosplay so as to hide my identity.” Rin answered, twirling their hair.

“What’s your screen name?”

“You’ll laugh.” Really he would, the spawn of Satan going by a name that involves angel.

“I’ll only laugh if you’re Yoru no Tenshi.” Mephisto rolled his eyes before seeing Rin’s quite frozen form.

“Welllllll” They trailed off.

“You’re getting me tickets to the next conventions you’re scheduled for,” Mephisto demanded.

“What’s in it for me?” They quirked their eyebrow up as they cocked their hip to the side.

“What do you want?” Mephisto narrowed his eyes at his sibling.

“You’re our current guardian while dad’s in the hospital, right?” Rin smirked at the man.

“Yes.”

“I want you to sign off for a motorcycle license and get me a motorcycle. Do that, and I won’t just get you into vid con, but I’ll get you VIP passes, Platinium, not gold, and an invite to some of the parties the other content creators have.” Rin held their hand out as in the offer.

“Make it for the next three years, and I’ll even let you customize the bike,” Mephisto argued.

“Deal.” Rin grinned as he shook their hand.
