~Present Day- Beacon Hills, CA, USA~

Stiles felt so tired, all he wanted to do was sleep. However, the way the building rumbled jolted him back into awareness. He flinched at the screeching sound of metal being ripping apart. It was one thing for Stiles to know that Derek was in Alpha mode but it was an entirely different thing to hear how lost to his wolf, Derek had become. As a result, Stiles felt so guilty to be the cause of Derek's emotional instability. Had he known that he was tying his soul to Derek, he would have never gone through with the spell. It was why he made no movement to look at Derek as the werewolf made his way inside the room. Stiles prayed to God that his had chosen the right spell to fight the Darach's ritual. He waited until the Darach had begun her chanting before he quickly rolled off the bed and shoved her out of the circle. Stiles did not stop to watch as Derek killed her. He already known that was going to happen. He knew he was about to take a huge gamble, but he hoped it was worth it. Stiles apologized to Derek, as he began chanting his own spell. However, Stiles had not expected the flames that quickly consumed his entire body. It was then that he began to scream.

As quickly as the pain had begun, it vanished. The fire still consumed him but the flames just made his skin glow. Since he was no longer in pain, Stiles gave himself a once over. He was still covered in his own blood but his injures were completely healed. Stiles continued his inspection but stopped when tribal markings began to appear on both of his arms and traveled up towards his shoulders. Stiles yanked the collar of his shirt to the side and saw that the markings stop before reaching his neck. As a result, Stiles had not notice the girl in front of him until she spoke. She had long black hair, which went beautifully with her cream-colored skin and rosy cheeks.

The fire also surrounded her, but unlike his golden light, it was pink. She reached out towards him. She asked him if he was okay. It took a minute for his brain to process her question because it was actively translating her words into English. The entire thing was weird, since Stiles did not speak a word of Japanese. He did not know how he knew, but he instinctively knew girl was speaking Japanese. Feeling impolite, he introduced himself but the entire thing was just awkward. She introduced herself as 'Kagome Higurashi.'

"So do you have any idea where we are," he finally asked.

"No, I remember falling into the Bone-Eater's well with my cousin but I don't see him here," she replied.

"Bone-Eater's well? That doesn't sound too friendly."

"The well itself is fine. It's the interaction between me and the well that isn't so great," she stated.

"Why, what happens when you and it interact," Stiles asked.

"I travel back in time to Feudal Japan, a time where demons and spirits are real," she answered.

"Demons and spirits?! Well and here, I thought I had it bad. I only have to deal with werewolves, an ex-kanima turn werewolf—and yes, there is a difference between two—, werewolf hunters, an evil druid, and a banshee."

"And that's not bad for you," she asked skeptically.

"No, it is but demons always trump werewolves," he replied with a smile.

"True. So, how did you get here," Kagome asked.

"The evil druid I mentioned earlier, well she decided that she want to use me as a sacrifice. Apparently, she found out who my soul mate was and she was going to use a soul mates' bond to give herself a power boost. She wants power so that she can destroy this pack of Alpha werewolves. I sure why but it may have something do with her disfigurement. Oh, and I haven't gotten to the best part yet. Apparently, my soul mate happens to be an Alpha werewolf,—he is not a part of the Alpha pack—who happens to be her lover," he replied sardonically.

"Sounds like she's trying to kill you, in order to get you out of the way," she mused.

"Got it in one," he responded.

"Well at least your love life is better than mine. I fell in love with this guy, who happens to be half-human and half dog yōkai—by the way, a yōkai is what you would consider a demon—that is in love with clay reanimation of my previous incarnation."

"Ouch! Well, don't let that getchu' down. My soul mate didn't know I existed until I forcibly bonded myself with him," he sighed.

Kagome raised an eyebrow at his admission, "Forcibly?"

"Yeah, I know it sounds bad but that was the only way I could call for help. The spell itself was a huge gamble. In any case, how I was I supposed to know it was Derek," he exclaimed.

"Derek," Kagome questioned.

"Yeah, Derek is my supposed soul mate." Stiles answered.

"Okay, now we exchanged our life stories and established that both of our lives suck. How do we get out of here," she asked.

"I have no clue but I wonder if these markings will disappear when we do," Stiles wondered.

"What markings? Let me see."

Stiles held out his arm for Kagome to look at. She took Stiles' hand but the instant she touched his skin the symbols disappeared.

"Whoa, how did you do that," he asked.

"Not sure, but you wouldn't happen to be a demon, would you?"

"Nope, I'm 100% human. Why do you ask?"

"Well, I'm not exactly sure that you're completely human. However, the reason I ask is because I can purify demons and their demonic energies." Kagome replied.

"Okay, that's just weird. As far as I know, I'm human. However, if you are 'purifying' my skin then I think it might have something to do with whatever spell the Darach was casting. Do you think you could remove it all? I don't want to try and explain it to my dad."

"I can try," Kagome said as she began to channel her priestess energy into Stiles.

Now that Stiles was aware of her power, he could feel how it seeped into his pores. He had expected pain but he only felt an overwhelming sense of peace. After a few minutes, Kagome let go of his hand go.

"I'm sorry Stiles, I can't remove it. I feel like my power is being limited, which is weird because I'm barely tapping into it. Well, if you wake up with these markings then I suggest coming to Japan. I think we need to be physically present for this to work," Kagome said before Stiles began to scream.

As soon as Kagome had released his hand, Stiles could feel her residual energy traveling toward the area between his shoulders. The energy began to sting. After a few seconds, it just simply burned. Stiles screamed in agony. The pain had concentrated itself into two points that ran along the medial side of his scapulae. Stiles could feel the two points becoming slits as warm liquid—which he instinctively knew it to be blood—trickled down his back. The pain was excruciating, so much so that Stiles fell to his knees. He could feel pressure as something tried to push itself out from the two slits. After a while, the pressure, as well as the pain, faded. Along with that, so did his center of balance. Before he face-planted onto the floor, Stiles used his arms to prop himself off the floor. His breathing was still harsh. As he continued his self-check, noticed that his back had become extremely sensitive as he shivered in response to slowing trickle of blood flowing down his back. Once he was finished, Stiles looked up to Kagome. He was taken aback by the awe he saw in her eyes.

He cleared his throat, before he asked her what was wrong. 'Wings,' Kagome murmured. Unable to keep his head up, Stiles let his head hang between his shoulders. He blinked, when he opened his eyes he was no longer in front of Kagome nor was he lost in the hazy darkness. Moreover, he was once again in the same building where the Darach had held him prisoner. Stiles could tell because out of the corner of his eye he could see the blood surrounding Jennifer Blake's corpse. He looked up and saw Derek, Peter, Cora, Isaac, Boyd, Jackson and Scott looking back at him with the same awe he had seen in Kagome. He smiled before losing consciousness.

Derek watched in horror, as Stiles burnt alive. He struck the barrier with all his might, but the damn thing would not budge. He desperately suppressed his wolf's need to howl in distress because he refused to surrender to the utter hopelessness of the situation. Through the bond they shared, Derek willed his strength into Stiles. He hoped to God that it would be enough, that he would be spared him the heartache of losing his mate. He did not want to be the cause of losing another loved one, because he just knew that this was his fault.

Without warning, the barrier flung Derek backwards. Out of nowhere, a sudden gust of wind swept throughout the room. It broke the ring of mountain ash that surrounded Stiles. The unexpected wind had concentrated itself around Stiles, leaving the teen in the eye of the storm. The wind had not doused the flames, instead they merged to become one; leaving Stiles bathe in golden light. Derek and the others watched in fascination as it began to heal Stiles. The room settled itself, once all of Stiles' injuries healed. Stiles was no longer burning, instead the energy kept glowing brighter and brighter. However, the light so was not over as pink light flared from Stiles' right hand and steadily spread itself all over Stiles' body. As quickly as the light appeared, it vanished.

After seconds passed and nothing happened, Derek steeled himself and walked towards his mate. As soon as, Derek touched him, light around Stiles exploded. Derek immediately released his tentative grip on Stiles and threw his arms over his eyes. The rest of the people in the room did the same.

"Is it over," Scott asked as the light faded away.

"I hope so," Cora answered as she lowered her arms.

Once the light was over, Derek turned towards his mate and the sight before him left him speechless. Wings had sprouted out Stiles' back. The wings were huge as they arched over the teen. The dark colored wings were a perfect contrast to the teen's fair skin, giving him an angelic look. Aside of the teen's transformation, Derek could smell how exhausted the teen was.

When Stiles raised his head to look at him, Derek saw that Stiles' eyes were no longer the color of honey but a vibrant purple. After a moment, he was gift with smiled and it made his heart clench. As the teen fell unconscious, Derek rushed forward and caught him. It became much easier for Derek to hold him as the wings disappeared. Finally, both he and his wolf were content as they felt and heard Stiles' heartbeat.

~Past-Sengoku Period Japan~

After leaving the miko and her cousin in the infirmary, Sesshōmaru headed towards his private garden. He reflected over the events that had occurred earlier that day. His behavior baffled him. He did not understand why he had followed the miko or why he had waited for her return. It was the fact that he had waited that told him that there was something terribly wrong with him. He wanted to say that his actions were done out of curiosity, but he knew that was not the case. It was his beast's increasing interesting that had fueled his actions. The level of interest it had for her, disturbed him greatly.

'Why do are you interested in the miko,' Sesshōmaru asks his other half. He grew irritated at the resounding silence that greeted him in return. His introspecting was cut short, as he felt the unexpected burst of spiritual energy. Sesshōmaru quickly shifted back into his humanoid form and headed towards the infirmary.

Akihito woke up at the resounding slam of the door. He just stared at a red-eyed Sesshōmaru stalked into the room and towards Kagome's bed. It is then that Akihito notices the pink light surrounding Kagome's unconscious form. Her energy crackles against Sesshōmaru's own blue-ish white energy. At first, Akihito thought that the two energies were evenly matched but Sesshōmaru's energy brightens further and surrounds Kagome with it. After a moment, the energies faded away and Kagome is startled into consciousness.

"Wings! He had wings," she says as she tries to orientate herself.

Akihito immediately goes to her and helps her sit up.

"Who had wings Kagome," he asked as she clings to him.

"Stiles, he had wings. They were beautiful. It reminded me of an angel," she answers.

"Stiles? What's a Stiles?" Akihito asks, confused by her ramblings.

"Not what, but who," she replies as Akihito feels the tension melting out of her body.

"So, you dreamt of man with wings," he asks.

"No, I didn't dream him up. We met in the darkness, like an abyss, but then there was light. Such warm light and then there was fire. So much fire, all around but we did not burn," she answered as the tension in her body returned.

"Hey, shh, shh, it's okay," Akihito tried his best to calm her but Kagome was too caught up in the memory.

"No, it was my fault. I tried to cleanse him, but I failed and then he screamed! I tried to help but no matter what I did, I could not reach him and my powers were useless. I really thought I had killed him," she sobbed out.

Akihito held her close, Kagome's anguish horrible. However, he did not know what else to do. He glanced towards Sesshōmaru but the lord of the castle said nothing. The being just stared dispassionately at the scene before him, but expression was at odds with the tension that ran through the being's body. Akihito also noticed that Sesshōmaru's red eyes had also not faded.

Akihito's attention returned to Kagome as she spoke, "I don't even know what happened after the wings burst out of his back, because I regain consciousness."

"I'm sure he's okay. Was he still breathing when you left," he asked. He felt her nod.

"The fact that he's still breathing must mean he's alright, right?" Akihito felt her nod once more.

"Okay, why don't you get some rest and tomorrow we'll find a way to find your friend. Okay?"

Akihito laid her back onto the bed. It took a while, but Kagome had finally fallen asleep.

"Do you think this Stiles person is real," he asked abruptly.

"Yes. Although this Sesshōmaru does not like the fact she met him in the darkness." Sesshōmaru answered.

"Why do you think so and what do you mean by the darkness," he asked.

"She's a miko," Sesshōmaru said simply, before continuing, "The darkness is what you humans refer to as limbo. This place is small hole in time. It is extremely rare that two people would fall into it at the exact same time. In any case, this Stiles could be from the past, present or future."

"A hole in time," Akihito repeated dubiously. "I would say it is impossible but here I am, in feudal Japan. If Stiles is another time traveler, then how are supposed to find him?"

"This Sesshōmaru suggests that you don't," he said as turned and walked out of the room.

"Well, nice talking to you too," Akihito muttered before moving back to his chair and wondered how he was going to tell Kagome.

~Present, outside of Kansas state-lines~

Castiel appeared besides Dean. His charge jumped at his sudden arrival, which was no surprise.

"Cas, how many times have I told you not to do that," Dean said tersely.

"Several. I have come to say good-bye Dean. I am returning in Heaven," Castiel answered Dean before he felt it.

Castiel felt as the archangel Selaphiel's grace reconnected to the host. However, its presence was not the same. In fact, Castiel was sure it not archangel.

"Cas! Earth to Cas," Cas heard Dean say, as the human tried to get his attention.

"Dean, I feel the presence of another archangel on Earth. We must go and find them."

"Cas, I don't mean to be rude but with angel, especially archangels."

"I realize this, but there is something wrong and your hunter expertise might be needed. The grace of the archangel Selaphiel has reconnected itself to the host, but it not Selaphiel. Selaphiel's grace almost seems human."

"Are you trying to tell me that some poor bastard has taken in angel's grace?" Dean asked skeptically.

"Yes."

"Wouldn't that nuke the poor bastard," Dean asked.

"It is supposed to. The disintegration of the body is a failsafe, so that no one other than the true vessel can use its power. In any case, we must get to it before Raphael comes to smite them down."

"Great, just great. Fine, where am I headed," Dean asked.

"Beacon Hills, California."
