Agent McCall was demanding an answer out of the pair, but they both stood quietly, "Let me help you out here." He said heatedly, "This kind of thing usually begins with something along the lines of, "It's not what you think." Or, "I can explain.""

"Dad, let me help you out." Scott told him, "You need to leave." It was bad enough that his Dad was already in town as it is, but the sun was close to being set all the way and those demon warriors could be here at any second.

"I will." Agent McCall told him, "With a satisfactory explanation."

"Go get a warrant."

"I don't need a warrant." Agent McCall told him, "I'm your father."

"No, you're a gene donor. I got my hair color from you. And that's all I got." Scott told him, "So you're not allowed to play tough dad with me."

In that exact moment Melissa walked into the house and sensed the tension in the room quickly, "Hey, what's going on?" She asked.

"Maybe one of you should explain." Agent McCall told her. At the exact moment he noticed a shadowy figure enter the living room, "Scott, who the hell is this?" He asked he made his way into the living room.

Scott, Kira, and Melissa exchanged worried glances, "Dad, no! Dad, wait Dad." But it was too late. The demon warrior that had come out of the darkness took a stab at the Agent right into his arm. Melissa pulled him to a secluded corner as Derek burst in and started to fight with the demon warrior. The twins bust through a window together. Together the werewolves managed to eject two other warriors from the house.

"Mom, the ash! Mom, now! Do it now!" Scott shouted at her. Melissa quickly dropped a jar of Mountain Ash across the threshold. It formed a perfect line which completed the security barrier Deaton established at the house. The Demons couldn't get past.

Back at the warehouse, Chris Argent showed Silverfinger the shattered mask he had kept, "Starting to remember? It was 24 years ago." Silverfinger's face fell into recognition, "You know what they are, don't you?"

"They're called Oni." The man told him as he covered the mask back up, "They are demons. And they are unstoppable."


Derek had been touching the floorboard of the house, "All of the baseboards are ash wood?" He asked an impressed manner.

"Uh, yeah. It was Deaton's idea." Scott told him, until it sunk in, "And where the hell did you come from?"

"I've been following you." Derek confessed to him.

"For how long?" Scott questioned. He hadn't sensed Derek's presence at all throughout the day.

"All day." He said as if it were no big deal.

"Dude, does Stiles know about this?"

"She doesn't know anything about this." Derek told him, indicating at the last remaining Oni in the house. "And I want to keep it that way."

"Scott, this isn't good!" Melissa called out to him. Scott quickly rushed to his mother's side as she applied pressure to the wound. There was a lot of blood coming out of the shoulder wound even as Agent McCall was still laying down.

"How bad is it?"

"From the way that his arm is rotated, the tendon looks torn." She informed him, "He could be on his way to a collapsed lung."

"Mom, those things, they're not going to leave until the sun's up."

"At the rate he's bleeding, he's not gonna make it that long." She told him, "We got to get him to the hospital. Should we call Stiles' Dad?"

"I don't know." Scott told her. Scott looked at the gun that was still strapped to his father's holster.

"Is that going to just get more people hurt?" Melissa asked when she saw him looking at it.

"Maybe." Scott told her, "I don't think guns work on them." He said recalling Chris' story.

"Then what does?"

Back at the warehouse, "Nothing." Silverfinger told the Argents, "At least no man-made weapon. The Oni are a force of nature. You don't fight a tsunami. You endure it. And you hope that you're not destroyed in its path."

"Then how do we endure it?" Allison questioned him.

"One of you already has." He pointed over at Isaac who touched the brand mark on the back of his neck. Silverfinger held up a picture of a backwards five, "This is Japanese kanji for "self". This means he is still himself." He explained, "The Oni are looking for one who is no longer themselves."

"What do you mean no longer themselves?"

"Possessed." He explained, "By a dark spirit."


In the McCall living room, Kira found herself under investigation, "It's Kira, right?" Aiden asked in a menacing tone, "You going to tell us what you are?"

"What?" Kira asked already frighten by him, "What do you mean?"

"Aiden." Ethan said in a warning tone.

"Watch!" He told his brother, he quickly took a hold of Kira's hand and forced her to touch the barrier, that separated them and the waiting Oni in the kitchen. There were more outside the house as well.

Kira's hand repelled against the barrier, "See that?" He claimed to his brother, "She can't go through it either. So, what are you?" He asked with a growl.

"She's a kitsune, idiot." Derek said appearing from the hall. "Use your eyes. You can see it all around her." Kira looked confused as the werewolves as gathered around her, "The younger ones give off an aura. She just hasn't learned how to conceal it yet."

Derek caught the look of confusion on her face, "She probably doesn't know what kind she is either."

At the warehouse, "There are 13 kinds of kitsune. Celestial, wild, ocean, thunder." Silverfinger explained, "But there is one, a dark kitsune. They call it void. Or nogitsune. A kumicho." That was when it suddenly made sense all those years ago to Chris, "He was possessed by a nogitsune. It's what helped him rise through the ranks of our yakuza family. Nogitsune draws its power from pain and tragedy, strife and chaos."


In a corner Kira and Scott were having an argument, "It's not you. It can't be. What I saw around you, it didn't look evil."

"But isn't that what a shape-shifter does?" She questioned him, "Isn't that why a kitsune is called the trickster spirit? It's supposed to trick you." She looked at him as if he had lost his mind, "How are you so sure? How do you know I'm not the bad guy?"

"I've seen the bad guys." Scott told her, "You're not one of them. If you were Stiles would've known from the get go."

"How would she even know that?"

"She has a talent."

Back in the living room with the menacing Oni still blocked by the barrier, Derek was giving Aiden a glare. "I wasn't going to hurt her." Aiden told him.

"Not yet." Derek inquired.

"Why do you think we're here, Derek?" Ethan asked him, "For a study group? We're here to protect Scott. We're trying to fight for him."

"I'm sure you are. I'm sure you'd kill for him." Derek said in an unimpressed manner, "But are you willing to die for him?" They looked over at the unmoving Oni.

At the warehouse, "Do you know why I'm missing this finger?" Silverfinger asked, holding up his little finger, "Penance. There's a ritual called yubitsume." He explained to the blank faces, "Removing the joints of the little finger weakens your grip on a sword. When a katana is gripped properly, the little finger is the strongest."

"Why did they take your finger?" Chris asked him.

"They didn't take it. A yakuza performs the ritual himself and offers it to his superior." Silverfinger explained to them, "It was penance for a mistake. And it wasn't my only one I don't know what it was about the way I moved or stood that suggested to them that I was going to take them on. Because actually I was preparing to run for my life."

He turned his attention towards Chris, "That shot you fired saved me from looking like a coward before the survivors. For that humiliation, I wouldn't have to have given up my finger. I would've had to give up my head." He told them.

"I wish I could give you the answer you need, Mr. Argent. I owe you more than my life. I owe you my honor. I will tell you one thing, however. If there is a nogitsune among you let the Oni destroy it." He advised him. He looked at Allison, "Even if it is your own daughter."


The Oni have begun to pounding against the barrier. It shook the entire house. "What are they doing?" Kira questioned them.

"Testing for weaknesses." Derek realized as the ones outside the window followed suit.

"Guys?" Aiden noticed that the one in the living room had produced a small hole in the barrier, "We have a problem."

In Scott's room, "I need to speak to Scott." Agent McCall told Melissa.

"You're kidding, right?"

"Don't patronize me Melissa." He said to her, "You know why...You know why I really came back, don't you?"

"And as usual your timing sucks." She shot back at him, "You're not talking to him. Not like this. So, you stay awake and we're gonna get you out of here as fast as we can."

Back in the living room, Scott was on the phone, "Allison, please tell me that you have something." He begged her, "They're here. They're trying to get in. And it looks like they're gonna' be able to do it." The hole in the barrier was getting bigger.

"Okay, okay listen. They're Japanese demons. They're called the Oni. They're looking for someone possessed. Someone with a dark spirit attached to them." She told him.

"A nogitsune." He remember from reading the book.

"How'd you know that?" She asked him, but received nothing, "Scott?"

"Just tell me what else." Scott rushed at her.

"Okay, they won't hurt you. They know you're supernatural but once they do this check, once they realize that you're not carrying with you this dark spirit, then they won't hurt you, I promise." She told him. Scott looked over at Kira, "All they're looking for is the nogitsune."

Scott hung up the phone and Kira could see the look on his face.

"I'm right, aren't I?" Kira asked him, "They're looking for me."

"They're looking for a dark spirit."

"Scott, we're going to have to do something." Derek told him already with his claws out.

"Don't do anything." Scott told them.

"Is he serious?" Aiden asked the other werewolves.

"I said don't do anything." He told the wolves, "Trust me."

"I hope whatever insane idea you have works," Derek told him stepping aside, "Because if you get hurt Stiles is going to be pissed as it is."

The demons burst through the barrier, while everyone else did stood still. The Oni reached for Scott and Kira, stared at them with their glowing eyes and branded each before letting them drop to the floor. Then they disappeared.


At the hospital Stiles woke-up in a dark room. She got out of the bed confused. As she opened the hospital room's room, she looked up and down the halls and see that they are abandoned. She made her way down the hall.

She made her way to one of the surgery suites. There, she was confronted by the Oni. She looked at the Oni with a stare and lets one get close but as it reached up to touch her neck, Stiles grabbed it's hand. She then forced her hand into its chest and pulled out a firefly. The Oni turned to smoke and disappeared.

Agent McCall was being wheeled into the emergency room with Scott, Melissa, and Derek, "Hey, stab wound to the left chest." Melissa said as she ran alongside the paramedics, "Possible collapsed lung. Pulse is weak."

"I'll find Stiles." Derek told Scott as he noticed the Alpha conflicted with following his dad or choosing over his friend. Scott gave him a nod as he followed the others.

Derek was making his way down the halls, when he heard sounds coming from one of the surgery suites. When he walked through the door he noticed Stiles standing in the middle of the room back away from him. The room didn't smell right and Stiles smelled completely off as she did last night.

"Stiles?" He asked hesitantly, "You okay?" He asked her.

"Yeah, fine." She told him, turning toward him. The smell was then gone as she gave him a smile and Derek was hit with a feeling on contentment, "What's been going on?"

Derek wrapped his arm around her shoulder and guided her out the room, but on the floor a firefly buzzed. Its light suddenly goes out as it first crumbled to dust then gets blown away in a puff of black smoke.


Derek followed her home and all the way into the house, "That's insane. Is he going to be okay?" She asked once, they made it to her room. Stiles laid down on her bed with Derek's arm wrapped around her.

"Yeah," Derek assured her, "Why you were at the hospital anyway?"

"I felt sick and I went to see Melissa," She told him, "Only because I knew she wouldn't call my dad."

"Are you feeling better now?"

"Yeah, apparently I just needed a good night's sleep." Stiles said softly and gave him a small smile.

"Is this about what happened that night?"

"It's been on and off honestly." She told him, "Adding the spark and everything I'm just having a hard time adjusting to it."

"You could've told me."

"And have you worry?" She questioned looking at him, "I don't think so."

"Remembered what you promised me?" Derek said looking back at her.

"Yeah, I do." Stiles whispered as he rubbed a hand down her cheek, "Do you remember yours?" Derek stilled for moment and gave her a nod.

"You know I'm going to want some answers from you."

"I know," Stiles said softly, "And as much as I love this, I need to sleep and the last thing I want is my dad to come and see you in my bed." Stiles told him, "You should probably go or else he'll shoot you for real."

Derek gave her a smirk and got up from the bed. He placed a kiss on top of her head before heading out his window exit. "If something happens-"

"You'll be the first I'll call." She told him. Derek didn't sense anything wrong or off about her. She seemed normal and the Oni were only going after shape shifters, aside from Landon, as far as he could tell. He made his way out the window, but that didn't stop the uneasy feeling he had from the hospital earlier.
