"Ngh!" Sayomi grunted as she blocked Hiei's sword with her sickle.

Before she could parry, he swept her legs out from under her. She lost her balance and her guard as she fell hard on her back.

She inhaled sharply through clenched teeth until she felt his knee dig into her abdomen and the sharp edge of his sword at her throat. His stern glare made Sayomi submit and tap out.

She did her best to keep her breathing under control to avoid getting cut since he refused to let her up. She glared up at him and arched a curious brow. Is he gonna get off any time soon?

Hiei's red eyes narrowed as he said, "This is your fifth loss. Why aren't you fighting back more?"

Sayomi glanced down at the sword then back up at him. He reluctantly sheathed his sword, but kept her pinned down with his knee to her chest and a hand on her shoulder. Finally able to relax a bit, she said, "I haven't been getting enough sleep. I'm just tired."

"You're a terrible liar," Hiei said flatly.

Sayomi scowled and said, "It's not a big deal. I just have a lot on my mind."

"You mean your brother," he corrected.

She bit her lip and avoided his stare. Should I tell him about that night? The encounter with Yasuhiro the week before made her realize she wasn't safe anywhere. Even worse, he wanted Hiei and her friends out of the picture.

When she fell silent, Hiei realized he guessed right. He squeezed her shoulder to draw her attention back to him. "We'll worry about him later. For now, just focus on your training."

Sayomi reluctantly swallowed her words and nodded. After Hiei pulled her to her feet, she dusted herself off and put some distance between them to get ready.

She took in a deep breath and let it out steadily. Her aura covered her body like a second skin as she settled into her fighting stance. "Ready whenever you are."

Hiei charged his aura as he slipped into his own stance. Then he dashed forward and started punching.

Sayomi blocked and dodged most of his strikes while maintaining constant physical contact. She guided his fists away from her and struck as soon as she created any openings.

Though Hiei was slightly frustrated with the fighting style, he managed to get in his own attacks. Once he had enough, he swept her legs out from under her and pushed her back.

Sayomi fell into her cloak and reappeared behind the swordsman. Expecting the tactic, he did a spinning back kick. She blocked in time, but the force of the attack sent her back through the air. Damn. He's not letting up at all.

She crashed into a pillar and dropped down to the floor with a roll to her feet. She glided through the shadows of the training dungeon to close the distance. If that's the case, then I really should take this more seriously.

Hiei turned to her as soon as she solidified to attack. His Evil Eye glowed in the darkness, drawing her attention. It was enough of a distraction for Hiei to strike.

At the last second, Sayomi faded into shadow, letting his attack phase through her. Then she solidified next to him and kicked him in the back.

However, he quickly dodged the attack. Then, he ignited his fists and punched her stomach.

"Gack!" Unable to phase through it, the attack knocked the wind out of Sayomi and left a burn.

"Haa!" Hiei followed through with a quick barrage of punches.

Unable to block or fade, Sayomi dodged to the side with a hand to her stomach. She used her aura to mend the wound while her other hand reached for her weapon. She turned just in time to block Hiei's sword. The swordsman vanished and closed in from a different angle.

Sayomi stopped healing and released the chain from the sickle. She sidestepped and pivoted on her feet to maneuver out of his way. Then she used the chain to tangle the sword and yank it down towards the floor. She shrouded her sickle in darkness and slashed, releasing a black crescent of aura.

Hiei dashed out of the way and struck again from another angle. She turned and parried his attack. They danced around each other with a series of parries before Sayomi managed to hit his hands with the weighted end of her chain.

Though Hiei held onto his sword, Sayomi could see the bruises forming on his fingers. Realizing he wasn't going to relinquish his weapon, she tangled the chain around his hands and the blade, binding him to his sword.

Hiei narrowed his eyes and dashed forward.

Sayomi raised her sickle to block his strike. Before she could react, Hiei vanished from her view. An instant later, he had her wrapped in her own chain. He smirked when she noticed his hands were still bound at the end.

The chain dug into her body as he pulled it tighter. When he brought his blade to her throat, Sayomi faded into the shadows and manifested next to him. She snatched the chain and quickly wrapped it around the swordsman's throat.

Hiei raised his blade in time to keep the chain from choking him. He used his sword to push the chain enough to duck out of it and sweep kick Sayomi's legs.

The demoness lost her balance and recovered with a roll. She pulled the chain and caught her sickle as Hiei closed in. As he attacked, he said, "You'll need to do better than that."

Sayomi gritted her teeth and held up her defense. He's not even giving me a chance to dodge or attack. What am I supposed to do?

"If you can't beat me, then how do you expect to beat your brother?" Hiei challenged.

Sayomi's pupil's dilated as she thought of fighting Yasuhiro. She thought of the power he wielded so long ago and tried to imagine what he could do with his new strength. What if I can't beat him?

Hiei noticed the change in her expression and took advantage. He hooked her knee and pushed her down to the floor. He kicked the sickle from her hand and mounted her with his sword to her throat. He narrowed his eyes when he noticed her gaze was unfocused.

"Let's just say that soon I'll be able to hold you in my arms and you won't want to escape."

Yasuhiro's words echoed in Sayomi's mind. She couldn't hear Hiei calling her name or see him in front of her. All she could see and hear was her brother.

She stared up at him as he pinned her down with a sword. Her body shivered beneath him as fear froze her in place. Though she wanted to look for Hiei, her eyes felt drawn to his malicious stare.

Yasuhiro glared down at her and said, "You're not leaving me much of a choice here."

When Sayomi blinked, she saw Hiei staring down at her with what she could only describe as worry. She blinked again and quickly sat up to look around the chamber.

"Sayomi."

She snapped her attention back to Hiei. Is he really not here?

The swordsman rested his hand on her head and asked, "What's wrong?"

Without thinking, she said, "I saw Yasuhiro."

Hiei's concern switched to a guarded glare as he turned to search the room. When he didn't sense or see anything, he turned back to Sayomi. "Let's take a break."

When they made it to their room, Hiei turned to Sayomi and leaned back against a wall. He crossed his arms and said, "I don't sense him at all. Do you mean you saw him before now?"

Sayomi stood by the door and focused on her breathing. She did her best to calm her nerves before she spoke. "He showed up in a meditation a few days ago. Now I thought I just saw him pinning me down with a sword. For a moment, I thought he was really there to kill me."

"What did he tell you in your meditation?" Hiei asked. After she told him, his bloodlust became nearly palpable. "That won't happen."

Sayomi sighed and looked down at the floor. "It's not like I want it to happen, either. I just can't help thinking about what he's planning. No matter how I try to figure it out, none of it is good."

"Maybe that's the problem," Hiei suggested.

"What do you mean?" Sayomi asked, raising her gaze to meet his.

"You're thinking about it too much and it caused you to see things," he explained.

Sayomi bit her lip as she thought about it. He might have a point. Ever since he showed up again, I've been worrying about it. But how do I not worry about it?

As Sayomi became lost in thought, Hiei watched her expression cloud over with worry. He pushed off the wall and approached her. Her eyes had drifted back to the floor, so she didn't notice him until he lifted her chin so she could look at him instead. "You're still thinking about it."

"I can't help it," she whispered. "How do I not think about something like this?"

Without warning, Hiei leaned down to capture her lips. Her eyes widened for a brief second before she closed them and kissed him back. Then he pulled away and leaned in closer to whisper in her ear. "If you need a distraction, then focus on me instead."

He nipped her earlobe, earning him a small gasp as her fists grabbed onto his shirt. He smirked and gently licked her ear before he pulled back to look at her. Her face was flushed and her breathing rhythm picked up from the sudden sensation.

She stared at the smirking demon. His eyes pierced through her and she could only feel the need to pull him back. Please...

Hiei's eyes narrowed as she tugged on his shirt, trying to pull him closer. He leaned in until their breaths mixed together, their lips almost touching. He kept his eyes locked on hers. His voice became lower and huskier as he said, "If we continue, I won't be able to stop. Are you sure?"

Sayomi hesitated. If we do this... Once mated, then the only way to separate is through death. Yet, if we don't, and Yasuhiro shows up, then we might end up regretting it. If I had to choose...

A low growl rumbled in Hiei's chest as her lips crashed into his. In an instant, he had her pinned to the bed beneath him. He devoured her mouth as her hands tangled in his wild hair.

Her hands glided down the nape of his neck, then over his shoulders to feel the toned muscles of his arms. He raised a hand to cup her cheek before gliding down along her side to her waist. She let out a satisfied sigh when she felt the warmth seep through her shirt.

Nipping at her lips, he slipped his hand beneath the fabric to explore her smooth, cool skin. As she arched her back, her hands found their way to Hiei's back where she dragged her nails down through his shirt.

Sayomi couldn't think. All she could do was feel. She felt the burn of his touch and the restraint in his movement. All she wanted was to feel more of their need for each other.

Soon, the heat became too much and she needed to breathe. She pushed the fire demon away to remove her shirt and cloak. She breathed in the fresh air and looked up to see Hiei had also removed his shirt.

Though she had seen him shirtless plenty of times, she still couldn't get over the sight of his physique. She blushed when she noticed the primal desire in his eyes.

He leaned down and captured her lips in another kiss. Then he trailed kisses down her chin and neck until he found the sweet spot on her collarbone. When he heard her gasp, he gently bit down. Her hands shot up to his hair where she held him in place. He bit and licked until she moaned, making him smirk. Then he trailed down lower until he reached the bandages that covered her chest. He bit on the edge of the annoying barrier and started to tug it down with a soft growl.

Sayomi looked down at him through half-closed eyes. They snapped open when she heard the rip of the bandage in his teeth. He used a finger to tug the rest of them down. Feeling embarrassed, she tried to cover up with her arms.

Hiei raised himself up to look at her. Her face was red and she glistened with a layer of cold sweat. He could feel his own sweat against the cold air, but all he cared about was the woman beneath him. He leaned down to kiss her lips and murmured, "Don't hide from me."

He guided her arms down with his hand as he kissed her again. Then his hand roamed over and around her torso freely. She melted under his touch and shyly started to explore his body. When her arms wrapped around his neck to pull him down, he lowered himself to take one of her breasts into his mouth.

She let out a sudden moan from the new sensation. She could feel his tongue tasting and playing with her as his teeth gently teased her. Unable to resist the pleasure his mouth elicited from her, she cradled his head to her chest, urging him to continue.

While he granted her request and shifted his attention to the other one, his hand roamed lower until her pants got in the way. He nipped at her before raising himself up to taste her mouth. He slowly grinded his hips against hers, letting her feel his need for her.

She moaned into the kiss as his erection sparked a new sensation within her. Hiei found one of her hands and guided it down to stroke him through his pants. She hesitated, feeling intimidated and embarrassed for touching it. He gently bit her lip and guided her hand up and down until she started doing it herself.

As he enjoyed her touch, he untied the red sash at his waist and guided her hand to feel him directly. She gasped, surprised by the size and heat of him. Hiei growled when she stopped touching him and urged her to keep going as he pressed himself into her hand again.

When she resumed her motions, he kissed her and returned his attention to her pants. She let him loosen them, but she still felt too nervous to remove them completely. To help her relax, he slipped his hand down to rub her through her underwear.

Sayomi gasped as she felt a tremor of pleasure shoot through her body. Wanting to hear her voice, Hiei gave her more attention. Though she stopped stroking him, he only cared about the sounds she was making. She clung to him until it became too much and she tried to move away. She managed to twist out from under him, but he wrapped his arm around her waist to pull her back.

Hiei held her back against him as he continued to play with her. Then he turned her head back to drink in her moans. Unable to escape, all Sayomi could do was quiver under his touch and lean back into him.

Once her underwear was damp, he slipped his fingers underneath to explore more thoroughly. The move earned him more sounds from her throat. He listened and teased her until she was on the verge of breaking. Then he slipped his hand from her pants and licked his fingers to taste.

Sayomi blushed as she collapsed forward on the bed. She was out of breath and her body felt hot all over. She kicked off her pants and felt instant relief as the cold air hit her legs. She stared up at Hiei as she tried to think through the haze of euphoria he put her in.

Hiei noticed her stare and leaned down to trail her body with more kisses. As he moved further down, he licked and bit her in various places to test her reactions. He continued to tease her until he reached her underwear.

Sayomi felt helpless. He could melt her with the softest touch, or make her writhe in his arms. Either way, she couldn't deny how good it felt. Then she felt a breeze and found herself completely exposed.

She tried to cover up, but Hiei pinned her wrists down. He traced kisses along her curves until he was able to taste her. Sayomi gasped as she felt his tongue roam and savor every inch of her.

She clenched the sheets in her fists and arched her back as she ascended to a higher degree of pleasure. When she reached a new peak, her body trembled and Hiei held her in place, looking up at her as he licked his lips.

Sayomi was left panting on the bed as Hiei slipped out of his pants. When she noticed, her face turned scarlet. I don't think I can do this…!

Hiei noticed her hesitation. He pinned her underneath him and said, "Relax. I won't hurt you."

Then, he guided one of her hands down to touch him again. She bit her lip as she started stroking him. The look made Hiei growl and lean down for a kiss. All she could do was submit to him and taste herself on his tongue.

After a few breaths, Hiei leaned back and pulled up. Then he guided her head down. When she hesitated, he said, "If you return the favor, it'll hurt less and make it easier."

Sayomi looked up at him before looking back down. Without giving herself the chance to back out, she dipped her head and started tasting him.

Hiei rested his hand on her head as she shyly licked the tip and took it into her mouth. It was warm and had a salty taste, but she didn't dislike it. As she got used to the taste, she started bobbing her head up and down while her hand continued to rub him.

She gagged when she tried to take in too much and Hiei gently pushed her back down on the bed. He mounted her and slowly started grinding his hips against hers. The move initiated a new sense of need from Sayomi. She wanted more and raised her hips to grind with him.

When he slipped inside, she let out a gasp of surprise. A sharp pain shot through her and she clung to Hiei as she endured it. He kept still and only leaned down to kiss her. He moved down to the sweet spot on her collarbone and gave it special attention.

The pleasure started to overwhelm her until the pain melted away completely. She was past the point of backing out and all she wanted to do was feel. She pulled herself closer to him so he could go deeper.

Hiei looked down at her lustful stare and grimaced. She was begging him for more. Her instincts took over and all she wanted was him. He fought down the urge to let his primal desires loose. Instead, he slowly gave her what she wanted. He gave her time to adjust before he started moving at a more natural rhythm.

Sayomi moaned as he picked up the pace, sending her over the edge. Her back arched, pleading for more. When her body quivered, Hiei held her close and pushed her further. She clung to him and dug her nails into his slick back.

As they reached their climax, Hiei sunk his teeth into the juncture between Sayomi's neck and shoulder and she bit him in return. He guided her down to the bed and pulled her close so he could lick the wound.

Sayomi smiled and cleaned the mark on his neck, holding onto him tenderly. Mine...

"I knew you'd come with me willingly, Sayomi."

Sayomi's eyes snapped open. Her body stiffened and the bliss of the moment was snuffed out with cold dread. She pulled away and saw Yasuhiro holding her with a satisfied smile. "B-but..."

Her brother pulled her in close and kissed her cheek. "Now you won't need anyone else."

"No..." Sayomi tried to shove him away. "Don't..."

"Sayomi?"

"Leave me alone!" Sayomi yelled. Her aura flared and pushed him off of her.

There was low thud as his body dropped to the floor. "Oof!"

"Huh?" Sayomi blinked and saw Hiei getting up from the floor. He glanced at her in confusion as he dusted himself off. Her eyes quickly darted around the room and landed on him again. "I thought..."

Realization flashed in Hiei's eyes. "Did you have another hallucination?"

"You're not leaving me much of a choice here."

Sayomi's eyes stared through Hiei in a daze. "Oh no..."

He reached for her shoulder. "What's wrong?"

Her frightened eyes focused on him. She whispered, "He used his curse on me."

Hiei's scowl hardened into a murderous glare as he pulled her into his arms and held her. "That bastard just earned a one-way ticket straight to Hell."

After they showered and got dressed, Sayomi did some deep breathing exercises to calm her nerves. Though she was aware of Hiei watching her, she did her best to ignore him.

I know he's worried, but it's not his fight. I need to be the one to take care of Yasuhiro. When she opened her eyes, she was calm and resolute. I'm the only one who can help or finish him.

She stood up from her seat on the bed and looked at Hiei. Then her eyes traveled down to the mark on his neck. Her hand automatically raised to cover the one on her own neck.

Hiei reached out to lower her hand so he could see it. "Do you regret it?"

"No. I just..." Sayomi bit her lip as she tried to organize her thoughts. "I was just thinking that I should at least keep it hidden."

"Why?" he asked.

Sayomi blinked at him and arched her brow. "Does it really need to be so obvious?"

"It's supposed to be. The point is to deter other demons from trying to claim you." Hiei's scowl darkened. "If anyone needs to know you're mine, it's your brother."

Sayomi winced at the mention of Yasuhiro. "Won't that make things worse?"

"The moment he cursed you, he lost the privilege to keep breathing. Whether he knows or not won't make a difference. Besides..." He slipped his arm around her waist to pull her closer. "I'm not hiding it."

Sayomi felt the heat return to her body as he leaned forward to kiss her neck. Then she watched as he stepped away and tied his sword to his waist. "Are we going back to training?"

"No," he answered. "We're going to kill him."

"Right now?!" Sayomi tucked her weapon away and followed him out of the room. "Shouldn't we let Mukuro know?"

"There's no need. If we put it off any longer, you'll only get worse." He kept his hands in his pockets and his stride was long and quick. "When did you say he showed up again?"

"About a week ago." Sayomi almost had to jog to keep up. "I thought you wanted to focus on training for the tournament, though."

"It's only been seven days and you're already hallucinating. The sooner we kill him, the sooner you'll recover, and the sooner we can get back to it."

Sayomi heaved a sigh and said, "Fine, but let me be the one to finish him, okay?"

"If you don't, then I will."

Sayomi frowned, but didn't argue. Instead, she said, "We still need to find him first. I don't have any ideas for where he could be."

"He'll save us the trouble and find us first. We just need to leave the fortress."

"How do you know?"

"It's what I would do," he automatically answered. "After cursing you, I would stay close but out of sight until you were alone. Then I would deal with you swiftly."

Once they were out in the forest, Sayomi sharpened her awareness. Is Hiei right? Is Yasuhiro really close by? If he is, then he could be hiding in the actual shadows. She looked around the shaded area. If I merged with the shadows, would I find him?

"Let's go," Hiei said, interrupting her thoughts. "Just because he can find us doesn't mean we need to be easy targets."

"Does that mean we won't get to sleep?" Sayomi asked.

"We can sleep and still keep watch, but we would be better off resting during the day." He looked at her. "Shadow demons are stronger after dark, so I'm assuming that's when he'll strike."

"You're not wrong," she confirmed. "But we don't know anything about what he can do now. My memories are outdated and not very clear, so we're going in kinda blind."

"You're slowly losing your mind," he reminded her. "That's all he needs for you to seek him out. He's already set the trap, so all he has to do is wait. Wait too long, and you won't be stable enough to kill him."

"He's right, Sayomi. You'll be safe with me."

Sayomi froze. Standing in front of her was the very person they were looking for. Her eyes widened and her breathing became shallow. "Yasuhiro?"

"We'll be together soon. It's what Mother wanted, after all." He reached out his hand to touch her. "Sayomi..."

As soon as his hand touched her shoulder, she slapped it away and stepped back. Then she noticed Hiei watching her. She glanced down and noticed his hand was turning red. She closed her eyes and bowed her head. "Sorry."

"Don't apologize," he said. "This is why we're looking for him now and why I'm coming with you. I would've been fine with leaving you to handle him alone otherwise."

"You'd really trust me to be able to handle him alone?" Sayomi asked.

"I'd let you fight him alone," he clarified. "I wouldn't trust him alone with you altogether. Now that I know he's willing to curse his own sister, there's no chance in hell."

Sayomi frowned. "I didn't mean for you to get involved. I was really hoping I could handle this myself."

Hiei stopped walking and turned to face her. His calm stare made her stop in her tracks. "I don't mind staying out of your fights, but I won't standby if you're in real danger. Right now, your sanity is at risk and that is unforgivable."

He has a good point. I can't fight if I can't tell an illusion from reality. I just wish it didn't have to come to this. I was hoping to try to save Yasuhiro, but at this rate, that's looking less and less possible. Sayomi looked down at her black nails. If this is really the only way, then Hiei's right. Sooner is better. I just hope I'm strong enough to do it.
