A/N: The promised longer chapter, it turned out to be very long. Now, I shall be apologized. If you wanted a Rin/Yukio action, here is some…AND VERY OOC /headbang

(4)Tiresias who?

Yukio didn't bother to wait until his, sorry, her older brother wake up. She sharply turned to Shura, who didn't cease her laughter immediately, and quickly said, "The snakes! They did this to me!"

Shura wiped her tears away with her fingers, seemed like Yukio had realized what caused this. Or probably, it was just nothing but wild guess and she didn't actually know what caused this. There was still confusion in her voice.

"Do you know anything about this, Shura-san?" she asked again. Shura had to bit her bottom lip to stop from laughing. Please, Yukio's voice was so feminine and it was enough to send her into another fit of laughter.

"I can't say that I really know about this, more like I've only heard a knack of it," Yukio frowned at her, "But, now that you mentioned about the snake, I think I have an image of what happened. Were the snake mating?"

The now female exorcist nodded eagerly, "Yes, yes, they were, and i-"

"You did stupid thing like poking or disturbing them, I know. God, you should have known how rude it was for you to see mating couple, let alone disturbing them," she cut her off, shutting Yukio effectively in the process.

The girl-turned-boy felt herself flushed once again. Oh trust her, she knew how wrong and rude it was. Then she realized she had almost apologized to the snake. Shit, she should have done that. Now because of some stupid thing she dubbed as foolish-human-pride, she got changed into a girl.

"They were angry at me, weren't they?" she quietly asked, face still flushing.

Shura decided she actually like to see Yukio flushing like a girl, she could use this for some blackmail material. Wait, Yukio was a girl now. "Of course, they were. I'd be mad too. But rather than changing their genders, I'd rather kill them at sight."

Yukio mentally thanked the snakes for not killing him right away. They were capable of changing his gender, she had started to fear other things they could probably done to her. Then it caught on him that Shura actually knew something about this, she probably knew how to turn Yukio back into a male.

"Please tell me more about this, Shura-san," Yukio pleaded. He actually hated pleading to Shura, she hoped she there was no need for her to go as far as lowering herself in front of the red haired woman, but if she didn't do so, Shura'd surely come with humiliating taunts.

The older woman let out another signature laugh, she could get use to Yukio's pleading as well. "Have you ever heard of Tiresias?" Seeing the look on Yukio's feminine face was enough to tell Shura she knew nothing about this, "In Greek mythology, Tiresias, a boy, prodded a mating snake with a stick. He then got turned into woman and actually lived with it. She even got herself pregnant!" Shura squealed excitedly, stressing the word pregnant more than necessary.

Yukio let out an indignant and horrified shriek. This Tiresias actually got pregnant as if pregnant with child? Was Shura saying he, Okumura Yukio, could get pregnant as well? She felt utterly sick as she imagined pregnant woman with their big stomach, wide hips, and swelled legs. Don't forget the extra fat that with no doubt would come together. Yukio quickly shook off any image of her with that appearance, she was so not letting anybody got her pregnant.

"What happened then? Did she change back into a he?"

Shura sighed disappointedly, "Unfortunately, Tiresias came across the very same snake and prodded them again. She changed back into a man."

Yukio twitched at the disappointed tone in Shura's voice. It's as if Shura didn't like the idea of Tiresias returning back into a man. It also meant Shura didn't like the idea of having Yukio back as a man. "So I can return back again into a man if poke these two snakes again?"

"Ah, well, I hope you cannot but maybe, who knows, " there she said it, she didn't want Yukio to turn back into a man. The whole situation was too amusing for her. If Yukio got normal again, she would miss her source of amusement.

Ignoring Shura's obvious disappointment, Yukio breathed out in relief. She could return back into a man! This thing was only temporary. Oh how she wanted to squeal in delight, the only thing that stopped her to was Shura's presence near her. If she showed any girlish act, Shura will surely humiliate her.

Yukio restricted herself from letting her excitement dripped through her voice, in most calm tone she could came up with, she spoke again, "So all I have to do now is find these snakes, then poke them with my gun, then I will turn back into a boy."

"Maybe, " Shura yawned. Her gaze then landed on Rin. The older Okumura was still unconscious, Yukio's uppercut had knocked the living daylight out of him it seemed. She got up, jabbing Rin's ribs with her finger. This caused Rin to yelp in pain and Yukio to glare at her.

"That was unnecessary, Shura-san, " Yukio hissed, she reminded Shura of angry cat that had her baby kitten disturbed, or maybe angry snake mother.

"Said she who knocked him unconscious," she sniggered, causing Yukio's already red face flushed even redder, "Well, you can tell him what he missed, I'm going to report this to the others."

With excited call that sounded like 'this is going to be fun!', Shura closed the door, leaving two Okumuras alone in the room with Kuro. Yukio sighed audibly and shift his attention to his brother who was rubbing his sore ribs with his right hand and tender jaw with the left one.

"Are you awake, nii-san? I'm sorry I hit you but what you did was totally unacceptable so I'm not going to apologize! We might be twin brothers, or sisters, or brother and sister, but no matter what blood relation we had between us didn't justify your act. If you did it to anyone, they'd consider it as sexual harassment, not that I didn't consider it as one, in fact I did consider it as one!"

Before Yukio's rant made his already pounding head pound even more, Rin growled loudly. This did shut his twin brother up. Rin felt his stomach drop when he realized that Yukio was no longer his twin brother, Yukio was his twin sister.

He took a hesitant glance to the boy, sorry, girl beside him. It was, with no doubt, Yukio, the splitting mirror image of him only with feminine features. Rin didn't need a sharp hit on the head to tell him that yes, he was awake, and yes, his brother was really turning into a girl.

Holly hell.

He was ready to pass out once again, hoping that this was only happening in his dream and when he woke up, he'd be greeted with masculine Yukio. However, the worry and fear on Yukio's face stopped him from doing so. Rin cursed himself mentally, he was stupid, how could he ever think of escaping this problem when he wasn't the one who carry the biggest burden.

If there was anyone who should think of escaping, it was none other than Yukio. The younger was probably more scared and confused than him, after all, it wasn't Rin who got turned into a girl against his will.

Suddenly, Rin felt his brotherly instinct kicked in. He was not going to let his younger sister through this alone. Especially now that Yukio was his younger sister, this surely made him more vulnerable, therefore, she needed Rin even more.

With this new determination, Rin quickly squared his shoulders and exclaimed out loud, "don't worry, Yukio, you don't have to be scared, nii-san will be there for you! I will not let anyone or anything harm you! We will somehow work this out, I swear!"

Yukio could only gape at her brother's sudden exclamation. She could see fire on Rin's eyes and how serious he was. If anything, Yukio felt grateful to know that Rin still care a great deal about her. She couldn't remember when was the last time Rin regarded him as nothing but a younger twin that needed his protection. Probably it was before Rin's Satan power woke up. Lately, her older brother only saw him as either someone equal or someone he had to surpass.

"Nii-san, " she smiled, feeling suddenly overwhelmed with Rin's resurfacing affection.

Yukio was so overwhelmed that she felt her body move without her consent and threw herself into her brother.

This caused Rin to blush heavily, once again that day, he was reminded that Yukio was no longer a boy but a girl. Her soft features were enough to convince him. Rin was confused about what to do at first, his gaze flickered to the his sister and Kuro who was looking surprised and as confused as him.

Rin decided that the right thing to do was to hold her so he circled his arms around Yukio's slim waist, breathing in Yukio's unchanging scent while trying to ignore the pounding in his chest.

Yukio suddenly realized what she did and stilled in his brother's embrace. She became aware at how strong those arms around her waist were, how broad Rin's shoulders were, and how his brother was now relatively bigger than her. Though he was the older brother, Rin had always been smaller than Yukio, only know Yukio seemed to acknowledge how his brother had truly changed into a man.

Damn, teenage girl hormones.

Despite the embarrassment, Yukio let herself became relaxed again in Rin's embrace, "You had grown, Nii-san," she whispered quietly.

"Huh?" Yukio asked, letting his tension go as well.

"You were always smaller than me and I never really realized it before. But now being held like this, I can feel how you've grown," she sighed comfortable, resting her head on his shoulder, "You're really the older brother."

Rin felt how his heart swelled with pride and something else. He felt like someone had told him he was now a Paladin, he felt like he had already defeated Satan. Yukio was actually praising him, and openly like this. He knew Yukio had occasionally praised him, but never about how worthy Rin was to be the older brother. The younger had did this in the older days, Rin realized how he missed those old days when he didn't have to deal with exorcism, when everything was normal, when Yukio was still smiling warmly at him instead of frowning upon his mistakes.

"Of course I am, I can't believe it took you to get yourself into a girl to realize this," he grinned, half joking. He could hear Yukio's soft laugh on his ears. No, wait, Yukio was giggling. "Did you just giggle?"

Yukio stopped laughing, or giggling immediately. She coughed and lightly hit Rin's back with her smaller palm, "Shut up."

Rin let out a hearty laugh that made Yukio eventually laugh again. After their laughter stopped, Rin noticed that Shura was no longer in the room, "Where's Shura?"

At the mention of Shura's name, Yukio felt herself scowling, the older woman had annoyed her with her taunts and teasing. But speaking of Shura, she realized she hadn't told her brother about Tiresias. Yukio shifted in her brother's embrace and tuck her head beneath Rin's chin, one hand snaked behind Rin's back. She blushed upon realizing how fit her brother was but quickly shook it off.

Rin, hands still around Yukio's body, adjusted his position so they both could get comfortable. He had noticed the scowl that had made a brief appearance on Yukio's face. He could tell that Shura had probably annoyed the life out of his younger sister, he would make sure to tell Shura not to disturb Yukio anymore even though he knew it was useless.

"Me and Shura-san had figured what happened, well, at least that's the closest explanation we had, " Yukio said.

"Elaborate more, please, maybe I can help."

Yukio nodded and Rin mentally swore when he felt Yukio's hair tickling his chin. Just when was the last time he nad Yukio had been in close proximity that now he was so jumpy when they were physically touching each other closely like this? He was becoming very sensitive with each contact.

She then told Rin about Tiresias and how he was changed into a girl after he prodded coupling snakes. Yukio also mentioned about the pregnant part and visibly shuddered, making Rin tightened his grip around her. The story then was put into curtain close with Yukio's theory about how she could change back into a boy.

At first, Rin was rather disturbed at the image of coupling snakes, he had never seen one before but surely, he wasn't going to like it. Then he was a little curious as why would Yukio did something like prodding coupling snake with his gun. But above all else, he was more bothered with the fact that Yukio could actually get pregnant.

The thought made his skin crawled with sudden protectiveness toward his younger sister, the first thing he said when Yukio finished her story was, "I'm not letting anyone get you pregnant."

Rin didn't realize that he was using one of his serious and deadly tones when he said that. All he had in mind was that he had to protect his sister no matter what it took. Yukio, however, noticed this, and couldn't help but feel a little bit scared. Still, she realized what his brother meant was just to keep her safe.

She was about to thank her brother for being so kind to her when she heard noises that sounded so much like someone had snapped pictures of them. She swore she also felt flash lights being directed at her.

Sure enough, they heard Shura's signature laugh coming from the door. The red haired woman was clutching a camera in one hand, the other was on her hip. She was looking so smug and amusement was present on her face.

"I see you two are quite comfortable with each other," she grinned, "Oh, I do believe you two are more than comfortable."

Rin felt himself flushed from head to the toe, so was Yukio. They didn't let go of each other until their eyes met, only then Yukio removed her hands from Rin and took out her guns from beneath the pillows. Rin felt strangely empty as his sister got on her feet, slowly advancing toward Shura with murderous intent.

"Give me the camera, Shura-san," she hissed out, hands flexing on her guns grip.

Shura cackled manically, slowly backing away from Yukio, "Not in million years!"

She then bolted out of the room with Yukio hot on her trails. Rin watched them left with dumb look on his face.

"Well, it's strange, isn't it, Kuro?" he asked his familiar who was now sitting beside him, "Yukio turned into a girl just because he disturbed coupling snakes. Why did he do stupid thing like that anyways? Sure he was curious, but, hell…"

Kuro nuzzled Rin's tight as the half demon lied down. He recalled how Yukio was perfectly fit on his embrace just like a glove. She was suddenly so frail and small as opposed with the taller and broader Yukio that he knew. A smile crossed his face but it was quickly gone when he realized something.

Rin shot back up to sitting position, eyes wide with fear, worry, and panic, "Yukio, what if anyone saw her like that? What would they do? Were they supposed to know about this at all? Oh shit, I got to run after her!"

In a blink of an eye, Rin was gone after his sister, Kuro following not far behind.

There was no one saying that they did know only a little about how this happening was going to change their life. They did know this was going to change their life, the only thing they didn't know was how big it's going to affect their life.
