"I'm sorry for the trouble, son." said old man who being carried by someone, walking on the bridge.

"It's no trouble." said Kohaku the one was carried old man on his back.

"I hate growing old. Spraining my back carrying firewood, how embarrassing!" said old man

"You shouldn't overdo it." said Kohaku with a smile.

"Kid, what's your name?" asked old man

"It's Kohaku." said Kohaku

"Kohaku, that's interesting name." said the old man

"Think so?" asked Kohaku as he and old man chuckles at each other.

"Kohaku, do you have place to stay tonight?" asked Old man

Kohaku stopped walking and shook his head. His vilages was destroyed by demon.

"Then come to my home. At least I can offer you something to eat." said Old man

"Thank you!" said Kohaku with a smile as he continues to walk while he looking up the sky. He starting to remember he killed his family and sister Sango. He feels so guilty himself for not resisting his mind controller. After he passed away, he met Naraku who revived him and erased all of his memories. Naraku ordered him to attack Sango, but he sees a blonde man who stopped him and got rid of his Shikon fragment that Naraku put it inside him. It all thanks to Naruto Uzumaki.

"Kohaku, are you okay?" asked Old man in worried looking at Kohaku with frowned face.

"Yeah, I'm alright." said Kohaku.

A hour later, Kohaku and old man were at the castle where he lived is. Kohaku saw lots of people were guarding their castle. Look like they were very serious. However, he heard the women were whispering something.

"Everyone was dead?"

"Yes. Everyone who was in the birthing room."

"A birthing room? Death?" asked Kohaku with a suspicious face.

"Oh yes, about that. A princess has birth a newborn baby. However, I heard men found them the following morning. They say there was something very strange about their deaths. " said old man

"I see." said Kohaku.

"Birds that suck blood?" a man asked Miroku who was the question to him.

"Yes, birds that suck blood. Have you heard of them?" asked Miroku

"Oh yes, there's been a huge uproar. I've heard many rumors about them." The man said

"Have they been seen in this area?" asked Miroku

"No, never seen them. Besides, we're so close to the castle." The man said as he turned at the castle. "No way would demons come here."

After Miroku thanks to the man, he went to Naruto and the group who were waiting for him.

"Well?" asked Naruto

"The demon birds never approach here before." said Miroku

"So, what's the plan? We have no clues about the location of the birds' nest." asked Kagome.

Naruto is looking at the castle. He senses lots of people at there and also found unfamiliar scent which is Kurama scenes for him.

"We'll stay here. I'm pretty sure demon birds will come here or the castle." He said

"Sounds like a plan." said Kikyo

"In that case…" said Miroku as he went ahead of them.

"In that case what? Just where you think you're going?" asked Sango as she grabbed Miroku's collar because he's talking to two young ladies. The girls giggled at Miroku while Sango is dragging Miroku away from them.

"Does he always do that?" asked Kikyo.

"Uh-huh." said Inuyasha as he nodded. He will never let Miroku touch his woman.

Naruto has a feeling about the castle because he senses an evil aura in the castle. However, there were a people who were guarding the castle.

"Hey, Kagome." He said

Kagome turned around at him.

"What is it?" she asked

"You guys go ahead. There's something I want to do something." said Naruto.

"Alright, don't be late." said Kagome.

Naruto smiled at Kagome for saying yes before he's walking to the castle. Meanwhile, Naruto is almost at the castle and saw two ladies are guarding the gate. He goes them, but they're pointing at him with their spear.

"Who are you, stranger?!" demanded woman.

Naruto must have thought that castle is overprotection.

"I'm just a traveler. I wanted to explore." He said with a bright smile as two ladies were blushing for seeing his smile.

"Well, you can, but just don't go near the princess." said the woman #2 as they put their weapon down.

"You bet…" said Naruto as his eyes were surprised that he saw Kohaku is walking and carrying the wood. "Hey, Kohaku!" he yelled. Kohaku stopped and turned around at Naruto as he waving at him.

"Naruto!" said Kohaku with a surprise. He surprised he meet his friend Naruto.

A couple minute later, Naruto and Kohaku were having a small chat about their owned journey.

"I see… my sister is here and alright." said Kohaku with a smile. He was glad Sango doing okay.

"Yep! What are you doing in this place?" asks Naruto as he looking around at the castle where his sense is that was an evil aura.

"I saw an old man need someone help to him, so I went to him and took him to this place." said Kohaku as he's pointing at the old man.

"That's a spirit!" said Naruto as he gave his dazzling smile to Kohaku.

Kohaku smiled back to him and glad to talk with him. Naruto always made him happy.

"What about you? What are you doing here?" he asked

"I came here because I heard the demon birds will come to this castle." said Naruto as Kohaku's face was shocked, but he went serious.

"I see… I'll be preparing for that… Naruto." said Kohaku

"Hmm?" asked Naruto

"Why are you in this castle?" asks Kohaku

"Came here to see you, of course!" said Naruto with a smile as he looked at the sun almost night. He doesn't want to be late like Kagome say. "Well, I have to go now before I'll be late."

"Alright, you'll have a good sleep and say hi to my sister for me! Would you?!" asked Kohaku

"Yeah, I will! See yaa!" yelled Naruto as he's running back to the village. He's running through the forest and almost to the village. He wants to tell Sango that he found Kohaku, but something wrong. He stopped and senses an evil aura… wait, there's more of them. He looked up and saw demon birds. They're heading toward the castle.

"You met your friend named Naruto." said old man

"Yes, he's very good friend." said Kohaku.

"That's good!" said the old man with a smile.

Kohaku smiled back to him, but he heard someone shout outside. He went outside and saw demon birds are attacking this castle. He quickly went back inside and grabbed his weapon Kusarigama. He slashed two of demon birds that were attack old man.

"Sango, you go help Kohaku! We'll take care of birds!" said Naruto as he draws his Furyunoha.

"Thank you." said Sango as Kirara flies to the castle.

The birds are dive down to Naruto and the group. Inuyasha used Kaze no Kizu on them. Naruto slashes the birds then used wind blade to hit them.

"Princess Abi! How dare you…" said Naruto

"Naruto, you're Naraku's enemy! So why protect this castle?" asked Abi

"What?!" asked Inuyasha

"Are you saying that Naraku is here?!" asked Miroku

Naruto remembered before that he sensed two auras in this castle. One of aura is Kohaku and other aura is dark and evil. The aura is almost as Hakudoshi's aura, but he was wondering why there are two of them.

"Naruto, I know what's your thinking." said Kurama

"Yeah, but why there are two of Hakudoshi? I mean the one in this castle." said Naruto

"Remember that monk told you that he tore him in half with his Vajra. And young monk saw Kagura took both halves of him." said Matatabi

Naruto remembers what Monk Shinsen says. He did tear infant in half, but why Kagura carried them with her.

"Yeah, I'm remembered that, but I'm going to find out." He said as he looked it up and saw Abi is attacking him. He dodges and blocking Abi's attack. Inuyasha jumped above Naruto and swung his Tetsusaiga Abi, but he hit the barrier that was protecting Abi. Abi smirked that she bought the spear with her, but…

"You think your barrier will help?!" yelled Naruto as he held the sand Rasengan and smashing the barrier. He broke it though, but he saw a spear made a smoke of the miasma. Abi flies fly up higher and lucky she saved.

"My birds! Burn their houses!" she yelled as she ordered her birds to turn on their fire. The demon birds turned into fire and dive down into the houses. They crashed and made a huge fire on them, so that people can run away.

"The house is on fire!" yelled Kagome

Naruto jumped on the roof and created 50 shadow clones. Along with 50 clones, Naruto and his clones did rapidly performing hand signs.

"Suiton: Suidan no Jutsu!" they yelled as they release the large water from their mouth to spread on the houses that caught in the fire. They wiped the fire out then the clones are protecting people.

"Nice one!" said Miroku

"Who are you?" asked the princess.

"My name is Kohaku. Hurry!" said Kohaku

"But there are demons outside!" said the princess

"Don't worry; my friends are here to save this castle. And I'll protect you with my life." said Kohaku as princess nodded and stood up. Princess and the others are following Kohaku to find the way out. They're at outside, but there're several birds are the diving attack to them. Kohaku is ready to attack, but…

"Hiraikotsu!" The Hiraikotsu slashed of birds. It was Sango.

Sango grabbed her Hiraikotsu and smile at his brother. She was glad she gets to meet him and he looks fine. However, a group of birds is attack her from behind.

"Youton Rasenshuriken!" The Lava Rasenshuriken flew at birds and made a huge explosion. The people were shocked that the explosion is very powerful. The one who threw is Naruto.

"Naruto!" said Sango in surprised.

"I'm a clone and looks like I'm here just in time." said Clone Naruto as he staring at the baby that princess was holding him. He senses a dark aura of him. "My lady, you need to get rid of the baby." Princess shocked what just he said.

"W-What?!" she shocked

"Naruto, don't be…" said Sango as she looking at the baby. He looks like a baby infant. "Isn't that…"

"Her real born baby already passed away, but that one…" said Clone Naruto before he about to destroy the infant, but infant starting to make a barrier and floating up in the air. He flies to the young girl with white clothes. It was Kanna.

"Kanna!" said Sango as she prepares to fight, but Kanna disappeared. "She's vanished…"

"Sango, stay with your brother." He said as Sango nodded before he release himself into a white poof.

"Take this!" yells Abi as she waves her flame at Naruto, but he dodges by jumping. After he jumped, he created a Sand Rasenshuriken from Shukaku's chakra.

"Jiton Rasenshuriken!" he yells as he threw in the air to target Abi. The birds sacrifice their life to save Abi. The Jiton Rasenshuriken made a huge explosion like a sand storm.

"Damn it!" said Inuyasha

"Lucky her birds saved her life." said Miroku

After the explosion is over, Abi is flying away from the castle because her birds got human blood enough for something.

"She ran away." said Kikyo as Naruto and Inuyasha sheathe their weapon. Naruto turned around and running to the castle where Sango and Kohaku is.

"Are you okay, Kohaku?" asked Sango as she checking on his brother

"Yeah, Sango. I'm fine." said Kohaku

"Are you guys okay?!" asked Naruto jumped on the roof and landed on the group. He rushed to them.

"Yeah, we're fine. I just saw…" said Sango

"Yeah, Kanna was here." said Naruto.

Few hours later, Naruto and the group were at outside of the village. Naruto told them about the infant baby is in the castle.

"You saw another infant." said Kagome in shocked.

"No mistake. My clone just saw another infant." said Naruto

"What was infant doing in that castle?" asked Miroku

"I don't know, but there was a connection between Naraku and the castle." said Naruto.

Kikyo is thinking about the infant. She remembers in few days ago, Monk Shinsen tore infant in half, but Kagura carried both halves of the infant and flew away.

"Naruto, do you have ever destroyed Hakudoshi?" she asked

"Yeah, but he keeps regenerate..." said Naruto as he starting to notice that he fought Hakudoshi and can regenerate. He should have killed Naraku's heart, but it wasn't. "Wait a minute! Couldn't be I just fought Hakudoshi with no heart!?"

"Just as I thought…" said Kikyo as everyone looking at her.

"What do you mean?" asked Inuyasha.

"The infant baby that one you found in the castle is the heart, no… Naraku's heart." said Kikyo. Everyone was shocked that the baby infant was Naraku's real heart.

"Naraku's heart?!" asked Miroku

"There was no mistake… that was definitely Naraku's heart." said Kikyo.

"Do you found Princess Abi?" asked Miroku as the group on their way through the mountain.

"Yes, I also sense Naraku's scent!" said Naruto as he and Kagome are riding on Entei. At that moment, Old Myoga randomly jumped on Inuyasha's nose before sucking his blood, but Inuyasha smacked on Old Myoga.

"Old Myoga." said Kikyo as Old Myoga jumped on Inuyasha's hair.

"Inuyasha, is it true that Naraku is at Princess Abi's nest?" asked Old Myoga

"There's no mistake!" said Inuyasha

"Tekkei will be at the nest." said Old Myoga

"Who's that?" asked Naruto

"Tekkei belongs to a group of birds which live in hell. More precisely, she's a demon connected to the other world." said Old Myoga.

"No wondered why Naraku want to ally with Princess Abi." said Naruto. The group arrived in a where Princess Abi and her mother, a very large demon bird with a blue flame.

"Is that Tekkei?!" asked Kagome as she looking at the large bird demon before Tekkei releases huge fire from her mouth. Naruto and the group dodge the fire.

"Naruto, have you all come to die, too?" asked Abi.

"Princess Abi…" said Miroku

Naruto is searching for Naraku. He senses his aura is inside Tekkei's belly, so that mean she ate him.

"Naraku is inside Tekkei!" he said

"That's right! He's in my belly." said Tekkei

"So you ate him?!" asked Shippo in shocked.

"No, he's still alive. I can still sense his aura." said Naruto. He knew Naraku wasn't easy enemy.

"Now then, stay still and be eaten by me!" said Tekkei.

Naruto and the group are prepared fight before Princess Abi ordered her birds to attack them. Sango threw her Hiraikotsu in the air and slashes the several birds. Kagome and Kikyo shot their sacred arrow at birds. Entei and Kirara tackle the birds while Entei breathes fire at them.

"As long as there aren't any Saimyosho, I can use my Kazaana!" said Miroku before he was going to use it, but Abi wave the fire at him. Miroku dodged her fire.

"Kaze no Kizu!" yelled Inuyasha as he created wave energy toward to Tekkei, but Abi is protecting her by using the barrier. Abi begins to charge at Inuyasha, but Naruto is in the air. He's in Sennin mode as he created Giant Rasengan.

"Senpou Odama Rasengan!" he yelled as he broke Abi's barrier down and slashed her left arm with his Furyunoha. Abi dropped her spear down, but no time to get it.

"Damn you!" yelled Abi as she flies away from Naruto and let her mother take care of them.

Tekkei had enough of Naruto and the group.

"I had enough of you!" She yelled before she's going to attack, but she stopped.

There's something moving up inside Tekkei's brain and wanted to get out. A tentacles pop out of her head then she fell down and died.

"Mother!" yelled Abi as she rushed to Tekkei before someone tried to get out of Tekkei's head. It was Naraku who killed Tekkei.

"Naraku!" yelled Inuyasha

"Princess Abi, well done." said Naraku

"I'll never forgive you!" yelled Abi as she charges to Naraku for killing her mother. Naraku smirked in evil before his small tentacles stabbed Abi's chest and betrayed her.

"You bastard! How dare you betray Abi!" yelled Naruto.

"She's weak demon. Thanks to me, you all… now able to go to the border between this world and the next." said Naraku as his hand turned into a claw and sliced Tekkei head off. Then the purple blood came out and fell down in the river.

"A river blood." said Inuyasha

"This have to be connect to the other world." said Naruto

"What're you looking at? This river of blood will not last." said Naraku as he following the blood of river.

"Everyone, let's go!" yelled Naruto as he hopping on Entei before Kagome behind him. The group then follows Naruto. Shippo heard someone is crying from the river. He saw people inside there then he screamed.

"What's the matter, Shippo?!" asked Miroku

"I can see things that look like human faces!" said Shippo

Miroku looked down the human faces in the river. It looks like they're human faces in water because Abi and her birds gave the blood to Tekkei.

"I see… these are the Tekkei's blood that was Abi and her birds gave human blood to her." He said. Naruto and the group are almost at the portal. Naruto saw a whirlpool which is the portal that connects to the other world.

"You guys ready?" he asked as everyone nodded. "Alright, let's go." as he and group dive into the portal.
