Kurokami growled and shot fire out of its three heads.

"Look out!" Itachi cried to Sasuke.

He raised his Susano'o hand and took the shot on. Sasuke, on his part, prepared the Susano'o arrow filled with black fire.

"Take this!" Sasuke cried and shot the arrow!

Kurokami only consumed the shot, much to Sasuke's shock.

"It looks like dark energy doesn't work on it," Itachi said, "It gets consumed."

Naruto looked back at Nao and Mao and asked:

"Are you ready yet?"

"Just some more time!" Nao cried, with his eyes closed. He was concentrating his chakra in his mind.

"We will be ready in an instant!" Mao added.

"Okay, then!" Black-Eyed Lao grinned. She bent down. Her long purple claws emerged and her vampire fangs sharpened. The white chakra fused all around her body. "While you're at it, I will help out the Uchiha boys!"

She bellowed in an infernal voice mixed with a horse's neigh and demonic roar. She rushed towards Kurokami at an immense speed. She jumped in the air. She formed a huge yellow energy circle in her palm and threw it at Kurokami.

"Huh? What's that?" Naruto was dazzled. He kicked black warriors at the same time.

"Sasuke! Itachi! Add your shots! Magnify it!" Lao cried.

Sasuke and Itachi heard her. They added their Susano'o shots to the yellow ball. The huge chakra circle hit Kurokami. The latter growled in pain - its tail was heavily injured.

"Good job!" Sasuke smirked.

The demon's wound healed fast, much to their consternation.

"Damn it!" Lao snarled.

"It looks like it's not enough," Itachi said.

Kurokami howled. It created a massive black energy ball out of its three heads and shot it at Lao and the Uchiha brothers.

Itachi covered Sasuke. He unified his Susano'o with Sasuke's and created a powerful shield. Alas, it wasn't enough to cover Lao. She was out of the safe spot.

Lao gasped in shock. The shot was sudden, so she didn't know how to counter it. She had put a lot of chakra in her earlier shot.

"Lao!" Gaara yelled. He ran to his orchid, like a madman.

Lao spotted him. She grew frightened.

"No! Stay back! Gaara!" she yelled.

Gaara didn't listen. He jumped in front of her and took the black shot. Lao was paralyzed from horror, while Naruto, Sasuke, Itachi, Sakura, and Hinata gasped.

Gaara coughed out blood and fell on the ground, covered in scars, burn marks, and black wounds. Lao shivered, with a mad expression on her face.

"Gaara!" Naruto ran towards him.

"Lao?" Hinata got worried.

Lao was shaking. She fell onto her knees. Her eye fixed in a strange direction. Tears were pouring down her cheeks. She stared at the floor. Her black eye closed. Her white chakra disappeared. Her right bang covered her right eye again, which caused her left human eye to open. It was frozen in a daze.

"Gaara!" Naruto cried.

He ran up to his friend. Sakura arrived too, to examine the Kazekage.

Mao and Nao opened their eyes, hearing all the fuss. They gasped in shock.

"Lao!" they cried.

They ran up to her. Lao clenched her fists on the ground so hard that her purple nails scratched the floor. She shrilled like a woman with her heart shattered to pieces. Her siblings froze. Naruto and his friends were no less frightened.

"Gaara! Answer me!" Naruto shook Gaara but in vain.

"Let me examine him!" Sakura cried. She put her ear to his chest and looked for his heartbeat. Shock overtook her. "His heartbeat! It's barely audible! Not only that!" She started infusing chakra into him. "Come on, come on... Come on!"

The Uchiha brothers were no less distressed, but Kurokami didn't let them wait for long. It growled and dashed at their Susano'os!

The Uchiha brothers were holding the demon off with all they could, while Hinata dealt with the black warriors.

Nao and Mao walked up to their eldest sister. Their eyes filled with pity at her sorry sight. She wept, staring at the floor in a daze.

"Lao, we..." Mao wanted to put her hand on her shoulder but held back. She could see her sister had lost all sense.

Nao heaved a sorrowful sigh, no less distressed.

A loud scratch on the floor reached their ears.

Nao and Mao looked at Lao in surprise. She moved.

"Sister?" Mao muttered. What did she intend to do?

Lao stood up. She glared with fury at the black demon. She clenched her fists so that they nearly bled.

Nao and Mao got frightened. Their sister's eye sparkled with determination. She wove special signs.

Nao and Mao gasped, for they recognized the signs.

"That's the Diyuma Call!" Mao cried. "Does she have enough chakra for it?"

"No, it's more than that," Nao said, "It's Diyuma Teleportation!"

The Leaf shinobi looked at Lao too.

"This game has gone too far!" Lao said. "It is time to finish this!" She infused her white chakra. "Black Eye: Diyuma Ultimate Teleportation Jutsu!"

She roared. Her right bang rose again. Her left eye closed, causing her right eye, the Black Eye, to open. Her white chakra moved fast, causing a wind to blow.

The friends saw a white flash. All of their other friends - Shikamaru and his team, and even their new acquaintance, Kokujin, appeared right before them.

"Shikamaru!" Naruto brightened up.

"Huh?" Shikamaru looked around in confusion.

"So, this jutsu worked!" Shao guessed when he saw Lao. "It summoned all of us in an instant?!"

"It's so good that you're here!" Mao cried.

Shikamaru and his team spotted Kurokami and widened their eyes.

"Oh god... What is that?!" Shikamaru got scared.

"That's a vast black energy demon," Sasuke answered from inside his Susano'o. "We must defeat it! Akuno unleashed it".

"And who's that..? No way, Itachi Uchiha?!" Shikamaru was dumbfounded.

"It is hard to explain right now," Itachi answered, "Let's just say I got summoned here on an urgent business. Now, let's finish the job before it's too late, and talk later!"

Shikamaru was still confused but decided to focus on the battle at hand, so he nodded at Itachi.

"So, what are we going to do?" he asked. Just then, he noticed the collapsed Kazekage. "Gaara?!"

Sakura was still infusing chakra in Gaara but with no hope.

"He's been injured," she told Shikamaru, "While protecting Lao. Never mind that, leave his treatment to me!" she frowned. "Now that all the siblings are here, we must kill this demon!"

"But how?" Shikamaru was uncertain, "It's so huge, even creepier than the Nine Tails!"

The Uchiha brothers were holding the demon off. Their Susano'os had already turned into skeletons.

"We won't be able to hold it off for eternity," Sasuke cried, "You must hurry up!"

"What do we do?" Hinata was worried. She had already finished dealing with black warriors, exterminating them all.

Shao wanted to speak when a demonic snarl made him halt. This dreadful voice was mixed with the one of Lao's:

"You will pay!"

"W-Who's that?" Naruto cried. He glanced at Lao. He realised she was the one who spoke! He exclaimed in shock: "Lao?!"

Shao frowned. He understood what it was all about.

"So, it is time," he said.

Lao wove signs. Her Black Eye flashed with anger. The siblings noticed her hand moves and guessed everything. They walked up to her and assembled in a circle around her. They wove the same signs.

"What are you up to?" Naruto asked.

"They're ready to unleash the Diyuma," Kokujin explained.

"Huh?" Naruto looked at Kokujin. He freaked out. "Eh? Who the hell are you?"

Kokujin chuckled. He crossed his arms and replied:

"Never mind! The main thing is that I'm an ally."

"Ah, alright..." Naruto shrugged. He turned back to the siblings.

"Inner Spirit Release!" The seven siblings cried.

Lao added in her newly acquired demonic voice:

"Black Eye: Diyuma Activation Combo!"

Huge spiritual energy appeared around the siblings in the air. The colours of the chakra emerging out of their bodies matched the ones of their cloaks. White chakra spread out of Lao, the black one out of Shao, grey - out of Nao. Tao went with light green, Gao - with red, Mao - with orange, and the twins with two shades of blue - Chao with the dark and Dao with the light ones. These colours of chakra merged, giving way to yellow chakra surrounding the whole circle of the siblings, with Lao in its middle. The yellow energy grew and took the form of a demonic horse.

The Leaf shinobi had widened their eyes.

"So, that is..." Naruto murmured.

"Yes, that's the Diyuma," Kurama answered in his mind. "It has been unleashed. That's good. Now, you should use your ultimate Tailed Beast form too, and let me take over! Diyuma and I are the ones who should put an end to this. If the Uchiha can lend us a hand too, that will be better!"

"Got it!" Naruto said in his thoughts. He unleashed Kurama's chakra and took the form of a demon fox.

Meanwhile, the yellow horse of the siblings took its complete form. It kept the siblings inside its chakra body. It was massive, even bigger than Kurama. It had eight feet, just like the siblings stated several times before. It had a fiery mane and tail, with seven lateral tails ending with sharp arrows. It had three long and sharp horns on its forehead, four vampire fangs, and two pairs of wings - one pair resembling that of a bat's, the so-called 'Demon Wings', and the other pair that of a bird's, known as 'Angel Wings'. Both of its eyes were pitch black, with white eyeballs, just like Lao's Black Eye.

Diyuma was unleashed. It took motion, rearing, and bellowing in a horrible infernal voice, resembling a demon's roar mixed with a battle-horse's fiery neigh.

"Oh god, it is so huge and creepy!" Naruto cried.

The hell horse was rearing and growling, causing wind blows and earthquakes. It got the Leaf shinobi nervous.

"Are those siblings in control of this thing at all?" Shikamaru exclaimed, being frightened.

"I hope so!" Sakura frowned, still infusing chakra in Gaara's chest, "Because that monster is our only hope against this black beast!"

But it didn't seem at all that the siblings had the hell horse under control. It was rearing, hitting its hooves to the ground, causing earthquakes, and nearly demolishing the ceiling!

"Ah!" Hinata shrieked, covering herself.

"Hinata!" Naruto cried worriedly.

But Itachi grabbed Hinata with his Susano'o and put her in a safer place.

Naruto sighed in relief.

"This is worse than I expected," Itachi noted, trying to stop the ravaging Kurokami together with his brother at the same time, "Looks like Diyuma took over Lao's mind and acts on its own! However, its heart is linked with Lao's, so the emotions are linked too, and because of that it is raged, just like Lao was back in her normal form! If someone doesn't put sense to Diyuma or awaken Lao's mind we'll be having problems!"

"Ugh, we already have problems!" Shikamaru shouted, "Besides, how can we put sense to it? Does it even know human language? It looks more like Ten Tails to me - a clueless ravaging beast... Ugh, this is such a drag!"

Naruto puckered.

"Well if it doesn't listen to us we will make it by force!" he clenched his fist.

"Naruto..." he suddenly heard Kurama's voice within. He cocked up.

"Huh?"

"Listen, Naruto... Diyuma is the grand spirit of eternal light energy... You cannot take something like that down on your own... Even my chakra combined with all of the Tailed Beasts wouldn't help against it so easily... So let me just take over, and I will try to rely my plan on everyone..."

"Oh... Fine. Go on!" Naruto nodded and switched places with him.

"Listen!" suddenly all of the Leaf shinobi heard Kurama's deep voice.

They all curiously looked up at the demon fox.

"What is it, Kurama?" Hinata asked.

"We must stop Diyuma's rampage if we want him to help us," Kurama started, "But that isn't so simple, even for me. Do you remember how the eldest of those siblings, Lao Shin, talked about Diyuma's guardian that last time? She said she chose Gaara as one. She told you already that the guardian is needed to unleash Diyuma's full power, but there's more to it".

"Huh?" the Leaf shinobi widened her eyes and listened attentively.

"Once one of the wielders of Diyuma, the leader of Lin clan, lost his partner in battle. Back at that time, Diyuma wielders still didn't have guardians, as nobody thought such a thing was needed. And the leader of the Lin clan was the father of the famous Lei Lin, the merger of the Shin and Lin clans. When this Diyuma wielder lost his partner, he lost also ties with her heart, and so he was grieved and stressed, which resulted in Diyuma's rampage. Whenever the wielder loses control of their emotions and fills up with negativity and depression, Diyuma's light energy tunes into negativity as well, and it causes it to rampage, thus the wielder loses control over it. To maintain Diyuma's power, and calm it down, the Shin-Lin clan worked out the system of guardians - so whenever Diyuma rushes on a rampage, the guardian could connect with its heart and tame it.

Briefly, we need Gaara to bond with Diyuma, so he can wake Lao, and the two of them with Gaara's lead could control it!"

"What?! Why is this power so complicated?!" Naruto cried, switching over again, "If she couldn't control it why the hell did she unleash it in the first place?! Gaara is knocked out, how can he help?!"

"Calm down, Naruto!" Kurama took over again, "The main thing is that Gaara's not dead. Take him to Diyuma and make sure they touch, their bond will do the rest".

"But how can we approach that thing?" Sakura was worried, looking up at ravaging Diyuma.

"Kurama and I will do it!" Naruto cried, "Get back, Sakura! Treat Hinata, she must be tired!" He took a battle stance. "Here we go!"

The huge demon fox rushed towards the rearing demon horse!

Sakura indeed avoided the demon battlefield and got off Gaara, whom Naruto took in his fox hand, rushing towards Diyuma.

Meanwhile, Itachi's and Sasuke's Susano'os used up all their chakra and vanished!

Itachi and Sasuke fell off!

Kurokami growled horribly and rushed towards them, wanting to consume them!

"No, Sasuke!!!" Sakura shrieked.

But suddenly something stopped Kurokami... It was ragedly growling, and it looked aside with its three heads, noticing Kokujin who was holding him with his black jutsu, having unleashed the Black Imp!

Now the black demons' battle began.

Meanwhile, Kurama reached Diyuma, but this latter kicked him with its front leg and threw him off.

"Ah!" Naruto cried, and frowned, getting up, rushing towards him again!

Diyuma was in a rage, growling horribly. It started creating a large yellow ball with its mouth!

"Naruto, be careful! Its power matches and even surpasses the one of Ten-Tailed Beast's!" Kurama cried in Naruto's mind.

"I just have to make him contact Gaara!" Naruto puckered, irritated, "Just shut your mouth you stupid horse!" he yelled and grabbed Diyuma by the neck, making it lift its head and send the shot above, causing the ceiling to break, and the shot was sent up in the sky, blowing into huge fire across it!

Sasuke and Itachi covered Sakura, Hinata, and Shikamaru with their Susano'o skeletons so they not get hurt by fallen ceiling pieces.

Meanwhile, Naruto brought the unconscious Gaara to Diyuma's chakra body and put Gaara on its back. Instantly, yellow energy threads emerged from Diyuma's back and connected with Gaara's back of the head, heart, main chakra point, palms, and feet. Diyuma first terribly and painfully growled, but then as if it got calmer... it settled down, stopping. He stood still as if he had a dilemma in his mind.

"What happened?" Naruto was confused. "What's wrong with Gaara?"

"It worked!" he heard Kurama's voice. "Now let's see if Gaara's will is strong enough to tame him..."

"What?! We don't know for sure?!" Naruto gasped in shock.

"Just calm down and wait!" Kurama frowned.

"Naruto!" they heard Sasuke's shout.

"Huh?" Naruto turned back. He widened his eyes - Kurokami was beating Kokujin's black imp, and Sasuke and Itachi had lost most of their chakra as well!

Naruto puckered and rushed forward, opposing Kurokami together with Kokujin and his black imp.

The battle of people was turned into a grand battle of demons.
