Okay, so this is the last chapter which takes place six months into the future. I just love the twins; Haru and Sumi are such cuties! I'm kind of thinking of writing another fic with them, but I don't know! Oh, Haru - just like his dear ol' daddy!

Hiei sat on the couch, holding black onesie clad Haru, with his hands under his son's tiny arms. He was staring into the baby's eyes, his eyes. Haru kicked his legs out, gurgling and blowing spit bubbles. Hiei smiled at Haru, his son mirroring him. Haru reached out grabbed Hiei's nose and giggled. Hiei chuckled and kissed Haru's tiny little hand.

"Hey, Hiei." Yusuke flopped down beside him, draping an arm over the back of the couch. "How're you enjoying fatherhood so far?"

Hiei shrugged, holding Haru in his arms. He smirked down at the baby in his arms, who was reaching up to pull at Hiei's hair.

"It's pretty nice." He said softly. "Look at my little boy – he's so tiny."

"Yeah, must take after his dad."

Hiei's eyes twitched, shooting a glare at Yusuke. Yusuke snickered, running a hand through his hair.

"Just kidding. Hey, is Kuwabara talking to you guys yet?"

"No, he's not." Shizuru said, coming out of the kitchen patting the white onesie clad baby girl on the back as she tried to burp her. "He just comes home from school then goes straight to his room. I'm sick of playing "Kazuma Says" with Yukina."

Every since Shizuru had given birth six months before, Kuwabara had been giving his sister and Hiei and almost everyone else except Yukina the cold shoulder. Whenever anyone wanted to talk to him, they had to address Yukina, who would got to Kuwabara's room and relay the message then return, telling them what he said.

" . . . Kazuma says he's still not going to talk to anyone . . ."

" . . . Kazuma says Eikichi threw up in his new shoes . . ."

" . . . Kazuma says you guys are out of toilet paper . . ."

"Is he talking to you yet?"

Yusuke shook his head, looking at Haru as he fell asleep in Hiei's arms, his head against his father's chest. He looked up at Shizuru, hearing the little girl burp.

"No, he just walks on by and pretends he doesn't even know me. I'm still playing 'Kuwabara Says' with Okubo." He sighed, relaxing into the couch. "Can I hold Sumi?"

Shizuru nodded and instructed Yusuke on how to hold the little girl. Yusuke set Sumi on his lap, laughing and poking at her chubby little cheek. She smiled and giggled at Yusuke.

Unlike her brother, Sumi was born with only a small soft tuft of black hair on the top of her head; now, tiny black spirals covered her head. She was a quiet baby, who seemed bored half of the time – especially with her brother. She was certainly taking after her mother.

"God, you guys are so lucky." Yusuke said, letting Sumi grab a hold of his finger. "These little guys are cute."

The three looked up as the door opened. Kuwabara stood in the doorway, a grumpy look on his face. He grimaced at Hiei and rolled his eyes.

"Hey, Kuwabara." Yusuke flicked his two-finger salute wave at his friend. "What's up?"

Kuwabara grunted and walked passed Shizuru, going straight to his room and not making eye contact with her. She jumped, hearing him slam his bedroom door. She sighed, covering her face with her hands then sliding them up through her hair.

"I really should have told him before." She said softly. "I should have –"

"Shizuru, stop." Yusuke said, adjusting Sumi in his arms. "Yeah, he's hurt that you guys didn't tell him, so what? He's gonna come around sooner or later. C'mon, you're his sister – and who could resist these two?"

He lifted Sumi up, covering his face with her. Sumi smiled at Shizuru, gurgling. Shizuru laughed and took Sumi from him.

Kuwabara flopped onto his bed, sighing deeply. He was still very angry with Shizuru for not telling him that Hiei was the father. He was very angry with Hiei for being the father. He was extremely angry that the two of them had had sex – and still were!

He groaned, covering his face in his pillow. It was so gross; he could hear them in the middle of the night giggling and talking and moaning softly.

"Why?" He grumbled, his voice shrill. "Why, why, why?"

He sat up, thinking so hard that he gave himself a headache. He asked himself the question that kept coming back to him – how did this happen? They had told him repeatedly that they didn't know, it just did. Nothing made sense! Out of his friends that he thought would be with his sister, Kurama was the number one on that list. Hiei was, of course, last; right after Okubo.

He made a frustrated high-pitched whining sound in his throat and threw his pillow at the wall. How was it possible that Yukina was Hiei's twin sister? That didn't make any sense, and yet it did. They did have some similarities; the way they walked, their eyes, their height . . . how could the love of his life be related to that frustrating difficult little freak?

His nephew and niece were extremely cute, he'd give them that much. He knew it wouldn't be long before that little girl, Sumi, had her big uncle Kazuma Kuwabara wrapped around that tiny pink little finger of hers. He smiled at the thought.

"The boy on the other hand," He said, shaking his head. "He's gonna be big trouble – just like his dad."

He turned to the door, hearing a knock on the other side. The door opened and Yusuke stuck his head in, his big grin on his face.

"Hello there!" He said goofily. "C'I come in?"

"What do you want, Urameshi?"

"Good, you're talkin' to me - I'm bored." He answered, stretching his arms above his head. "Shizuru and Hiei went out to go get diapers or somethin'."

He flopped down onto his friend's bed, falling onto his back. He smirked up at Kuwabara, snickering.

"Get outta here." Kuwabara growled, kicking at Yusuke. "I wanna be alone."

"Oh, c'mon, man! Give it up already!" Yusuke sat up, propping himself up with his hands and tilting his head to the side. "Come watch those babies with me."

"No way." Kuwabara grumbled, folding his arms over his thick chest in a huff. "I've washed my hands of those four."

"Oh, really?" Yusuke asked, standing up. "Then why did you get a job at the Arcade?"

Kuwabara yelped, jumping up.

"I just wanted to make a lil' cash, okay?" He said defiantly. "Is that a problem?"

"For what?" Yusuke smirked, putting his hands on his hips. "Just admit that you wanted to be a big boy and help our your sister with the twins."

"Wha – that's crazy!" Kuwabara sputtered. "Who said that?"

Yusuke arched a hairy eyebrow, cocking his head to the side. Kuwabara yelped again. He knew he was found out.

"Okay, okay." He sighed, scratching at his cheek with a finger. "Just don't tell, okay?"

"So you admit that –"

"Yes, Urameshi!" Kuwabara snapped. "I'm a big boy and I wanted to help out!"

Yusuke snickered as Kuwabara pushed passed him and left his bedroom.

Shizuru sighed, sitting down at a park bench. She felt worried about Haru and Sumi, worried about Kuwabara. Hiei sat next to her, dangling his feet. He held her hand, looking up at her.

"What's wrong, love?" He asked. "You know the twins are fine."

"I know, I know but –"

"But nothing."

He cupped her face in his hands, pulling him towards him. He smiled at her, resting his forehead against hers. She sighed again, looking away.

"Hey, look at me." He said softly, making her face him again. "Smile. I love you."

"I love you, too but –" Hiei silenced her with a kiss. "Hiei, what're you –"

"We've been away for five minutes. Your brother and Yusuke can take care of them. Relax, my love."

"But I can't, I –"

"Yes, you can." He said crisply. He stuck his bottom lip out in a pout, his eyes big round cute orbs that took up half his face. "At least, try – for me?"

She laughed then kissed Hiei. She stood, grabbing both his hands and pulling him up.

"C'mon, let's go."

Kuwabara sat in front of the battery operated baby swing for the twins, watching as Sumi went back and Haru went forth. He made faces at them, retrieving giggles from Sumi. Haru just looked up at Kuwabara with the same face Hiei gave him – the "you're an idiot" look. Kuwabara looked at Haru, eyes narrowing at the six month old as the swings stopped. He leaned down to get a better look at Haru when Haru jerked a leg out and kicked Kuwabara in the nose.

"Shit!" He exclaimed, covering his bleeding nose as Haru giggled evilly, clapping. "I don't think I like you very much."

Haru stopped clapping and gave Kuwabara another look, his tiny head cocked to the side. "Like wise!" his look seemed to say.

"He's just a baby, Kuwabara!" Yusuke said, crouching down beside his big friend. "He's harmless, no need to be a hater."

"I'm not a hater! He kicked me in the nose!" Kuwabara whined, wiping the blood from his nose on the sleeve of his shirt. "He's a little beast, that Haru."

Yusuke nodded then turned to see Kuwabara looking at him. They laughed loudly.

"Just like his dad!" They said in unison.

Sumi reached her little arms out to Kuwabara, opening and closing her tiny hands. He stood up and unbuckled her from the swing.

"You wanna be held, sweetheart?" Kuwabara asked sweetly, picking up his little niece. "You love your big uncle Kazuma Kuwabara, don'tcha?"

Sumi giggled as she straddled her uncle's hip. He poked at her chubby little cheek, tickling her. He cooed at her, smiling at her.

"You're just the cutest!" He gushed, tickling under her chin. "You must get those good looks from your mom and aunt Yukina."

"Look at you!" Yusuke chuckled, picking up Haru. "She's got you totally under her control!"

"Ha, you should really see her with Hiei." They turned to see Shizuru and Hiei standing in the open doorway. She smiled at them. "Sumi's such a little daddy's girl."

Haru made a whimpering whining sound, reaching out to Hiei in Yusuke's arms. Hiei smirked, dropping the shopping bag to the floor and going over to Yusuke. He took Haru from Yusuke, nodding a 'thank you' at his friend.

"So, you're talking again, little brother?" Shizuru asked, going into the kitchen and dropping the shopping bags on the table.

"What a pity." Hiei said sarcastically, smirking at Haru who giggled.

"Hey, shut up shrimp." Kuwabara grumbled.

"Oh, leave him alone, Kazuma." Shizuru said, standing in the entranceway of the kitchen. "Don't rip on my children's father."

"Yes, I just so happen to be huge where it counts." Hiei said, glancing at Kuwabara's horrified face. "Or at least that's what your sister says."

"Whoa, whoa, whoa!" Yusuke said, covering Sumi's ears. "Children in the room! Ever hear of 'too much information', Hiei?"

"I think I'm gonna vomit." Kuwabara mumbled, sinking into the recliner by the twins' swing.

"Hiei!" Shizuru smacked him on the back of the head before walking over to Kuwabara and taking Sumi from him. "Don't be gross."

"So, is Hiei gonna be living with us?"

"Hn. I have been for six months now."

"Yeah, stupid question." Kuwabara looked up at Shizuru. "We're not gonna move, are we?"

"We might when the twins get older."

"Can I ask you guys a question?"

"Wow, that was simple."

"Shut up, shr – Hiei." Kuwabara shot a glance at Hiei then looked back at his sister. "Could you guys at least try to be quiet at night when you two are . . . well . . ."

"Gettin' freaky," Yusuke added, sitting on the arm of the recliner. "It's sick, that's what it is. Especially when your walls are paper thin."

"You're not helping, Urameshi." Kuwabara shuddered at the thought. "But yeah, could you try to be a little considerate of the other people in this apartment?"

"Yeah, sure, Kazuma." Shizuru answered, kissing the top of Sumi's head. "Only if you promise to baby sit once in a while."

"Deal!" Kuwabara punched the air then fell back into the recliner, rocking it accidentally. "Hey, do you guys plan on getting' married?"

Hiei and Shizuru looked at each other, smiles on their faces then looked at Yusuke and Kuwabara, who smirked back at them. Haru crossed his tiny arms over his equally tiny baby chest, snuggling up against Hiei. He smirked at Kuwabara, giving his uncle a sideways glance that made Haru resemble his father.

"Go read the sequel."
