(1) You can't tell a snake to get a room, but at least you should apologize

A/N: I actually write something not depressing, gee. Non-established Romance. Basically, I'm kinda stuck with 'Not The Answer I Should Know' and I saw people started to write or draw fem!Rin, then I thought; Hey, why don't I write fem!Yukio? And here is this story. This was based on Greek Mythology where Tiresias poked coupling snakes and got turned into female.

By the way, sorry, the fighting scene sucked. This chapter is kinda boring and nothing particularly interesting happen, seeing as this is only the prologue. Also short, hope I can write more for next chapter. For the time being, enjoy and don't forget to tell me what you think.

He cocked his guns as he lined himself up with the trees, the demon he's chasing after had exceptionally sharp sight and quick feet. The only advantage he had was that the said demon was deaf, he could make sounds as much as he liked but he couldn't risk being seen.

After waiting for some time, the demon finally turned around from where he was. Yukio used this advantage to get a perfect aim and exterminated the demon once and for all. The first bullet landed right on its eyes, rendering its sharp sight useless. The second and third ones managed to lodge themselves perfectly on its hind legs, the fifth and sixth followed after and ended up in the remaining legs. The last bullet, the seventh, pierced through its skull.

The demon let out chilly and painful howl as it collapsed to the ground. He shot another bullet just to make sure it was safe for him to move closer. He approached the demon and nudged it with his foot, it's already dead. Yukio immediately contacted the HQ, reporting that his mission was clear and requesting permission to go back.

After the request was granted, he made his way out through the woods. The trees surrounding him were tall, looming over him like impenetrable walls. It was quite and dark as well, making it even more scary that it should be. If his students were with him, he could see how they'd act, most of them would act strong and Shiemi would fail to do so. His brother then would use this to show Shiemi how strong he was.

The thoughts of his students put Yukio at ease. Not that he was scared, he just felt unsettled. As he neared the entrance of the wood, Yukio suddenly heard rustling voice from behind the bushes. He whirled around, guns ready at hands. He quietly approached the said bushes, holding his breathe back. He mentally counted to three before using his foot to revealed what was behind the bushes.

He was torn between breathing out in relief and chocking back in surprise. The cause was none other than the sight in front of him, coupling snakes. Yukio had never seen one before, and frankly speaking, he was curious. The two snakes were twisted against one another, tangled as if they were united since birth.

Yukio didn't know what spurred him to do the next action, an act he'd undoubtly regretted forever and berate himself for doing. Using one of his gun,he poked on the snakes.

Immediately, the snakes let out a loud hiss. Yukio expected the snake to lunge at him so he prepared himself for the attack. However, the snakes didn't move, they only stared at Yukio with piercing red eyes.

The young exorcist waited. After seeing the snakes would do nothing to harm him, he put his guns back and actually was about to apologize to the snake. However, he realized that apologizing to snake was a quite a silly thing to do so he didn't say anything. Instead, he turned back and continues making his way back.

It was the next act he'd regret and loathed himself for.

Yukio woke up with strange feelings down below. When he said down below, he meant the down below between his legs, not down below on his feet, he meant, oh well, you know what he meant. It was a strange feeling, like that part was burnt, which was obviously a horrifying thing, but at the same time, it felt like a bucket of ice was put there.

There was another problem, he felt strange too on the chest. No, it wasn't a strange feelings like when his father praised his job for the first time, nor was it the strange feeling he felt when something amiss was going to happen. It's a physically strange feeling. When he said physically, he meant it was a kind of feeling he got when he was injured or came in contact with something.

From the bed across, Rin was already gone, he was probably training with either Shura or Kurou. Yukio let a smile crossed his face, his brother has been working hard these days. Rin was dead serious about kicking Satan's ass and he was glad his brother was actually putting his all into something. It wasn't that Rin was incapable of being serious, more than anyone, Yukio knew his brother was more than capable in doing so. Rin just lacked motivation and some push. Maybe it wasn't just a push, he needed serious shoving to actually start something.

Yukio was cut off from his muse when he felt sharp pain across his chest. And another one across his, you know, down below. He immediately clutched his stomach, he didn't know why it was his stomach that he clutched when the pain didn't came from there. It didn't matter though because the pain immediately crawled to his whole body.

He let his body fell back to the bed with strangled cry. His whole body started to burn, his skin tingled, his inside felt like someone had turned them into mashed potatoes, his toes curled, his vision grew hazy, and he felt like someone was pounding his head repeatedly with blunt object.

As if it wasn't bad enough, the pain across his chest and, sorry, crotch intensified. Yukio let out another pained cry as he curled like a fetus while holding himself. The pain was getting more unbearable with every ticking second. He had to bite into the sheet to keep him from shouting his throat sore.

Just what the hell happened? Did he do something strange yesterday? He didn't remember putting anything strange into his mouth, all he put inside was Rin's cooking. There was no way Rin had a cooking mishap, his twin brother's had been cooking since they were kids and never once he managed to hurt anyone with his cooking. If anything, Rin's cooking would likely heal everything.

So what caused this? Was this some genetic problem that sprung out when he reached certain age? Was this the replacement of Satan's power that he didn't inherit? Somekind of side effect? Could this be a mashou? Again, he didn't remember being wounded by any demon lately. He had returned from most mission completely harmless. Well, maybe not completely with minor wounds but not something he couldn't handle.

Suddenly, Yukio saw a pair of red eyes and heard a loud hiss. At the same time, the pain seemed to explode, making him scream out in agony.

'Could it be?' Was the last thing he thought before he blacked out completely.
