If you don't read my other (non-Lea) Blue Exorcist fanfic, you didn't see me apologizing for lack of uploads yesterday. Well, sorry. I didn't have school and was busy helping my parents clean and then building robots (to enslave humanity).

Rin: Are you going to do something evil…again?

NM: No…I'm turning you into a human!

Rin: Seriously?

NM: No

This story idea comes from lilKCsunshine and I'm really excited to write this one! The demon in this chapter, Twist, is going to have the same description as Ochiba from an early chapter. Hope you like it!

Rin and Yukio ran into the forest. All the exwires were sent on a mission to investigate a mysterious demon known as Twist. She was flying upwards to escape the two.

"Ah, Rin Okumura, I see that you have quite the secret, secrets are boring. But don't worry, I have a very interesting way to reveal your little secret." The demon said while summoning several black storm clouds. She then proceeded to strike Rin with lightning.

"Rin!" Yukio shouted.

"Don't worry, you will feel the same pain soon enough." She said as the exwires began to catch up. She ended up hitting all of them with the lightning.

"Can't have anyone missing out on the fun…now can we?"

Later…

Once everyone had finally woken up they noticed that Ochiba had disappeared. They filled out a report and simply left, after all, they had school the next day.

The next day (I guess that I'm in a time skip mood)…

The Kyoto trio was in their dorm room sleeping like they normally did (AN: No…really?) Bon usually got up first, and he did, like normal. However, when he woke up something happened, Bon burst into flames.

Blue flames.

In the Okumura's room…

Rin had gotten out of bed early for something to drink. On his way back to the room he accidentally woke Yukio up.

"Good morning Rin." His brother said in a slurred and half-asleep way. He sat up and noticed something black flicking around in the corner of his eye. "Can you get your tail out of my face?" He said irritably.

"I'm all the way over here, so how could my tail be over there?" Rin asked him. Yukio grabbed the end of the tail and yanked on it. He yelped and fell out of his bed. Rin, who was now completely awake, ran over to his brother. His brother was on the floor staring at the black, fuzzy object. Rin gasped and Yukio looked at him.

"I'm not a demon!" Rin said while feeling the tips of his ears to find that they weren't pointed. Rin then looked closer at his younger brother. "But you are."

"But how is that possible?" Yukio asked. He was now wearing his glasses and looking in a mirror to see what all had changed. He now had fangs, pointed ears, and a tail, all of which pointed to him becoming a demon. Rin, on the other hand, was a human again.

"Wait! What about the Koma sword?" Rin said while grabbing it out of his bed and unsheathing it. When he did instead of him catching fire, Yukio did. The handle of the sword began to feel extremely hot, and Rin dropped it. Yukio looked confused and picked the sword up.

"Isn't it hot?"

"No, why?" Yukio asked while putting the sword away. He handed it to Rin who pushed it away.

"Listen, I don't know what's going on, but I'm not connected to the Koma sword anymore, you are. Take care of it."

Later in class…

Well, just before class, actually. The Kyoto trio discovered that they weren't the only ones having an 'interesting' day. It seemed like everyone in the class had some sort of demonic features in one way or another. Shemi and Shima had fangs and could hear demons, Bon had a tail and occasionally caught fire, and so on. Rin walked in and they didn't even give him a chance to sit down.

"What happened to you?" Shima asked.

"What do you mean?"

"Seriously? We've all been having a weird day! We've all gotten demonic powers somehow." Rin's eyes widened.

"You too?" He asked.

"Why, are you getting them too?" Izumo asked.

"No but Yukio was." He answered. It was best to play along while they suspected nothing. Yukio walked in the room and immediately noticed that something was off.

"So it happened to you too?" Bon said.

"What do you mean?" Yukio asked and they explained what had happened.

"The only one here who it didn't effect is Rin." Bon said while pointing and the formerly half demon.

"Well, if it is a demon's spell, it will probably wear off." Yukio said. But, little did they know, it wouldn't.

The powers and physical traits changed around between them, however two things stayed consistent.

Yukio didn't just have demonic powers, it was like he had become a demon.

And Rin stayed human.

It went on this way for about two weeks until the Kyoto trio began to put two ad two together.

"What if Rin was a demon and then Twist's spell gave us his powers?" Shima asked.

"But that doesn't explain the blue flames." Bon said.

"What if it does, though?" Shima replied. Before anyone else could say anything a voice was heard.

"I was wondering how long it would take you!" Twist yelled. A black cloud of smoke appeared at the front of the room and she emerged from it. "How can you all be so smart and stupid at the same time? The one you call Rin Okumura is not only a demon, but Satan's son!" She shouted. Before anyone could process what she said she hit them with the same lightning that caused the whole fiasco. When she did everyone turned back to normal, but one thing was different.

Rin wasn't human anymore.

The second he became a demon again he grabbed the Koma sword off of Yukio's back and charged after the demon.

"Until next time." She said, disappearing in a cloud of black smoke. Rin put the sword away and turned around to face his now human classmates. Shima broke the silence.

"I always knew there was something weird about you!"

Hope that you liked it and it makes up for a lack of uploads yesterday!

Rin: You actually did make me human

NM: Yeah, but I like you as a demon more

Yukio: Meow that's what you said to me

NM: And that's because it's true, you two are 20% more badass as demons
