Yukio rang the bells to wake everyone up. "It's time for class."

"Awww Yuuuun…" Kuri pouted

"Buuuuttt…" Rin complained.

"Get your uniforms on." Yukio muttered.

Kuri sighed, going into the bathroom and changing, happy that there were slits for her wings.

Rin huffed and went to change.

Reiko changed into her uniform in her bathroom also noting accommodations for her tails.

Kuri came out. "Rin! What do you think?" She straightened her uniform.

Rin openly stared at her for a moment before blushing and muttering. "Y-You look g-good."

Kuri laughed and grabbed his hand. "Hope our teacher's cool!"

Yukio stifled a laugh.

"Something funny Yukio?" Reiko asked, coming out in her uniform.

Yukio stumbled a bit, then cleaned his glasses, which were fogging up. "You…look good."

Xxx

"Hello everyone! I'm going to be your teacher. My name is Okumura Yukio." Yukio stood at the head of the classroom.

Kuri blinked "Yun?!"

Yukio glared. "That's Okumura-sensei to you."

Reiko giggled.

Rin stared. "What?!"

Reiko pulled out her notebook out and rolled her eyes at how mad the other two were.

"Stop whispering in my class!" Yukio commanded.

"Sorry sensei." Kuri bowed her head.

"Now." Yukio began. "How many of you can see the hobgoblins?"

The hobgoblins began pulling against Yun trying to get to Kuri.

"Eep!" Kuri squeaked and hid behind Rin.

Reiko groaned "Fuck."

Rin got in front of her protectively.

A few people raised their hands, not knowing what was going on, answering the teacher's question.

"Those of you who haven't, line u—" Yukio was cut off as the goblins swarmed on Kuri.

"Everyone out! I'll handle this." Yukio cried as the students scattered. He took out his gun. "Reiko! Behind me!"

Reiko tried to help her sister.

"Get off of her!" Rin snarled getting them away from her.

"When we're you gonna tell me you were a teacher Yukio?"

"Now isn't the time for that!" Reiko exclaimed.

"Nngh!" Kuri cried as one of 'em bit her and suddenly ignited in blue fire.

Rin was pissed.

The bite was visible on her skin. "Ouch…"

Kuri grabbed the burning Rin. "Rin!" She hugged him close. "Don't."

Y was shocked as she calmed him before he was discovered.

Kuri hadn't seen the flames, only calming him on instinct.

Rin looked at her curiously. "But it hurt you…" He whispered calming down.

Reiko was amazed. "Wow."

Yukio watched Rin warily, eyeing the bite, remembering what he had read about demon marks.

Kuri pouting at the bite wishing for some reason that it was Rin's bite.

Rin touches the bite thinking the same thing and getting upset.

"That's all of em right?" Reiko looked at Yukio.

Kuri suddenly grabbed Rin and pulled him into a closet, then extended her neck to him. "Please? I-I hate having another demon's bite on me so…"

Rin's eyes widened. "What?! Seriously? You want me to…He looked at her neck.

Shots were heard outside. Yukio finishing off the hobgoblins.

"Please? I hate it! I feel…" Kuri lowered her voice "violated…" Kuri looked up at him. "Make it better?"

Rin didn't need to hear another word. He pulled her close and bit her neck, marking her.

"Hnn…" Kuri stroked his hair, making a soft noise of pleasure as Rin marked her.

Rin growled softly.

Kuri shuddered.

Rin smiled. "Mine." He suddenly kissed her.

"Mm! Aah…" Kuri bumped into the door and they fell out. "Uh…'

"RIN?!" Yukio cried. "What are you two doing?!"

Reiko stares at them. "oh….oh you did not!" She started laughing. "Oh my god you did!"

Kuri pouted. "We just kissed what's the problem?" She didn't understand.

Rin blinked. "Ah…well ya see."

"And I sorta got a hickey," Kuri admitted.

Reiko shook her head. "That's…sweetheart that's not…oh my god…"

Yun stared. "Um. That's not…" He snickered and whispered to Reiko. "They really don't know!"

"No they don't." Reiko whispered back and snickered as well.

Yun whispered back. "I mean isn't that like marriage?"

"Yeah it is actually. That's what makes this even funnier."

Yun looked worried. "But yknow…for demons…the urge is to uh…consummate…as soon as possible. Or else it will fade."

Kuri looked over at Rin "They seem busy. Look the hobgoblins are back. Hey! They're being nice now! They look sorry." Kuri pet them. "Sweet lil guys.'

"Yep. And no…sis don't pet." Reiko scolded.

They crawled all over Kuri nuzzling. "Rin lookit!"

Rin shoved em off and growled.

Yukio watched in was. "Hm…a rather elegant solution to the demon attacking…"

"Riiin!" Kuri shoveed him aside and snuggled the little goblins, maternal instincts in action.

"Makes things easier for sis…." Reiko pointed out.

"Kuri you sorta…like demons, don't you?" Yukio said incredulously.

Rin huffed.

"Well yeah, what's wrong with that? Should I hate them? Humans kill each other all the time too…what's the difference?" Kuri snuggled, holding one like a baby, looking at Rin and smiling.

Rin blushed and stared at her.

"This is so cool! I think Rin's hickey made them like me! Thanks Rin!" Kuri exclaimed, getting it but not getting it.

"Y-you're welcome." Rin stammered, still staring at her.

Yukio was still laughing a bit.

"…is class over then sensei?" Reiko shakes head a bit at her sister and smiled slightly.

Yukio sighed. "Yes. It's time for you to go to your next class. I think your learning about familiars."

"FAMILIARS?!" Reiko and Kuri exclaimed in stereo.
