Minato was stunned into speechlessness by what Enrai had just told him. Kushina saw this and took care of the questioning. "What...a sixteen-year-old girl? Being manipulated by someone with Sharingan?"

"Yes. And she had Nine-Tails chakra within her. Yang chakra, not Yin. Strange. I do not know how she came by it," Enrai said in his rolling-thunder-like voice. "Sabaku Sotaiso noticed a few blonde hairs. Roughly the same shade as Naruto's. It's a good thing she's so analytical."

"Her voice. What was it like?"

"She was distorting it. We cannot be sure."

"...Thank you, Enrai."

"Are you all right? You both look very shaken."

"It's just...another war, so soon...excuse us, Enrai."

"Of course, Milady." Enrai left.

When they were sure he was gone, Minato and Kushina embraced each other. "I didn't want to believe it..."

"I still don't, Minato."

"But...the doctors told us she was stillborn..."

"Apparently not. Or perhaps Madara revived her for his own sick, twisted devices. Planted seeds of a grudge she would never carry if we had raised her."

"...We can't mourn the time we never had with her being lost. Before anything...we need to tell Naruto."

Kushina nodded. "Yeah, we sure do."

Naruto was staring longingly at Ichiraku Ramen, wishing that he had the money to go inside and eat a bowl. His stomach growled so loudly it almost sounded like Kurama was about to break out.

"I know, stomach...but we don't have the money to go in..." Naruto lamented.

"Ah! Naruto! There you are!"

Naruto turned toward the voice to see his mother waving at him from just down the street. She jogged to him.

"Haah..whoo...there you are. Your father and I have been looking for you for nearly an hour, ya know?"

"Is something wrong, mom? Is Menma attacking already?"

Kushina shook her head. "No...but this is about Menma. Or rather...who she really is. Hold on, let me let your father know I found you..." Kushina rummaged in her pouch and took out one of Minato's special kunai. She stuck it in the ground. Moments later, Minato was there.

"Should've known he'd be here. You're always hungry, aren't you, Naruto?"

"Heh...yeah, until there are vegetables on the table!"

Minato had to force a smile. "Well, I can assure you that there won't be any vegetables involved here. But...this news isn't good news by any stretch of the imagination."

Naruto looked back and forth between his parents. "You both look upset. Is something wrong?"

"Naruto...we've been unintentionally lying to you for sixteen years."

"Huh? What?"

"Kushina, don't put it like that. Naruto...what your mother's trying to say is...we found out that you're not an only child, after all."

"I'm not...I'm not an only child? What, is mom pregnant?"

"No, Naruto. Menma...Menma is actually your twin sister."

Naruto was utterly shocked. "Menma...is my sister?" His anger quickly boiled up. "How long have you known this?!"

"We only just found out, Naruto. The doctors told us when you two were born...they said she was stillborn."

Naruto's anger faded as quickly as it had come. "...What's she like?"

Minato and Kushina were both surprised. "Huh?"

Naruto grinned. "If I've got a sister, I might as well know what she's all about, ya know!"

Their surprise continued for a moment longer, then Kushina started giggling. Minato followed suit, and soon they were both laughing.

"Ha...haha...oh..." Kushina wiped her eyes. "Sorry to tell you, Naruto, but she's been raised by an evil mastermind for all her life and is probably being manipulated by him even now. Plus, she wants to destroy the entire shinobi world. You probably won't get along too well."

"I'll wake her up, then!" Naruto clenched his fist. "I'll snap her out of whatever spell she's under!"

"Goodness...I haven't seen you this determined since you were taming Kurama...oh! Which reminds me...she has the other half of Kurama sealed inside her. The Yang half."

"Really? Maybe we'll be on even ground, then!"

Speak for yourself, Naruto.

Suddenly, Naruto found himself inside his mind, standing near Kurama, whose head was resting on his paws.

"Kurama? What's up?"

After that fiasco where Yoko stole my chakra, I'm not exactly in top fighting condition.

"No...? Well, couldn't we just give it our best shot?"

Not with a foe that dangerous. My yang half contains most of my chakra control ability, so the host would be able to compress even a Biju Bomb to a size not much bigger than a seed.

"Hmm...that does sound hard to fight against. What could give us an edge?"

She probably already knows about the Jutsu Entities, seeing as there were several at the summit. However, one you created with, say, the Biju Bomb or Planetary Rasengan or even Rasenshuriken would be very powerful. Perhaps more so than even Shinrai.

Naruto thought about it. "I dunno...I'd like as little outside help as possible. Maybe we could just create one. What would you recommend we use, Kurama?"

The Biju Bomb would be most powerful, but the hardest to make, I would think. Rasenshuriken would be easiest to control, but the least powerful unless you made one of straight Rasengan. Planetary Rasengan seems like the most logical choice.

"I see...that way, it would have both your chakra and mine in it."

Bingo.

"Hmm...I dunno, though. It seems like she uses Biju Bomb a lot. Could Planetary Rasengan stand up to that?"

From what you've said, you just want to defeat her, not destroy her. By that logic, Biju Bomb and Rasenshuriken are definitely out. And if you're going to do Rasengan, you might as well go the extra step and do Planetary Rasengan.

"Could she stand up to it?"

She's related to you. I wouldn't put anything past her.

"Planetary Rasengan, then. Thanks for your help Kurama."

Not a problem. I'll be here regaining my chakra if you need me.

"You mean sleeping?"

Heh...call it what you will.
