Chapter 6

"Hey Ramie, is it okay to leave without telling Gau or your brother what are we up to?" asked Kouichi as he waited for her to lock the front door.

The blond locked the front door. "We just going to our favorite Sensei who might know about our half demon friend. Beside it not like we doing something dangerous." She smiled and they headed out. "See I think someone here must know about Gau being half demon. I mean why else would he have his own apartment that is far from other students. Also Kumohira - sensei know Miharu's family since he was a teen, so he must know something about this. Also I don't want Gau to know that we are doing this research cause he might be mad."

They all were silent. Thinking over what the blond just said, knowing it might be true. "So it take all of use to do this?" finally asked the sliver hair teen.

"No, but Kumohira - sensei is really hard headed specially when it comes to secret like these, and he'll only listen to Miharu. That why Miharu and Yoite," she pointed to the young couple, "go see what he knows. Well me and glasses here," she pointed to Kouichi, "see what we can find in the library about this. Though I don't know what Shijima wants going to do?"

"I like to see that spot where curly-kun beat down those fake human?" she smiled. "So I be off bye."

"Who told my sister all about what been going?" said the glasses wearing teen.

"I did." Miharu raised his hand.

The sliver hair girl went off ahead. "Okay now," Ramie grabbed onto Kouichi, "Let see what we can find." The odd couple went off leaving Miharu and Yoite alone.

As the two walked hand in hand to the school, Miharu asked, "Are you sure you okay with this?"

"With what been happening in the last couple of days or sure I say week. Okay still," he squeezed Miharu's hand, "I know that all this getting to Gau. He is my only living relative and same goes for him, so I want to help in what ever way I can. Even if he doesn't want me to."

Miharu smiled, "Just remember it not just the two of you. You have me and Gau have Raikou-san."

"I know but Raikou is a different story. As Gau only relative I have to take the big brother role and see if Raikou good enough for Gau." The two got closer as they headed to the school .

Evening

Raikou woke up finally around six o'clock and stretched his arms above his head. He felt something moving under the sheets. The young adult smiled, "Gau it time to get up." He pushed Gau gently. The movement under the sheet shock no. "It late."

"Nooo." Raikou couldn't help but to think that the black hair sounded like a child.

"Come on you should at least get up. It already six."

"It's too early."

"Six is early?"

"Yes that is early." Gau moved more under the sheet.

Raikou wasn't getting anywhere. "You are acting like a child." Raikou pointed out. "Is it because you didn't sleep well?"

"No," Gau finally got out under the sheet and sat up. "It just that I not a morning person." Raikou let a small laugh. "What so funny?"

"You hair." He pointed out.

Gau blinked a couple of time. He moved his hand to his hair. A frown appeared on his face. He usually had bad bed hair but thanks to his horns it was worst. "Stop laughing," blushed Gau, "it is embarrassing."

"Okay," Raikou placed his hand on the teen's left horn and started to rubbed it. "I am sorry I laugh at you but…" he the quickly pinch Gau's left chcek, "I get to pinch you cause you slept in." Gau could see that smile but feel the dark aura around the young adult. He let go of Gau's cheek. "Now let see what we going to have to eat." The two left the bedroom. They notice that everyone was gone, but all their stuff was still their. "Do we want to even when they went?"

"Uh no." Gau looked for any notes. "Um I going to take a shower."

After the he was done and Raikou was in, Gau noticed the book. The half demon pick it up and started to read it. He filled through the pages hoping to find something about horns. Once he found the chapter on horn, he started to read it. At the beginning it just talk about how horns are the sign that a half demon's blood is getting ready to take over the human blood though it just a sign, for a half demon blood won't take over until the eighteenth birthday. It then went on talking about certain horns can gives certain abilities. He then went on looking up about horn type. He was hoping to find about his type.

Gau was about to turned the page when Raikou come back and wrapped his arms around Gau neck. The teen quickly jumped and dropped the book. "Did you found anything out?"

"We…well it was saying…" Gau took a deep breath to calm his nerves. "that our horns have certain abilities."

"Our?" Raikou pointed out and moved awhile from the teen.

Gau froze for a bit and then nodded. "Well I not a human anymore."

"Yeah but that doesn't make you a demon either. We…" Raikou meant the whole gang, "can seal your blood again then you won't become a demon."

"It might not work. I mean the blood is stronger then before."

"Then we try something else. You never know until you try it out and see what happens. Still it those fake human is what we should be worried about." Gau nodded. "Where or who made them."

"Well they can only be made by alchemy and sorcery combine together, but no one haven't taught or use alchemy even before the Demon War." The two were silent thinking it over. Suddenly the lights were flicking off and on. "That strange," commented Gau. Suddenly they bust into pieces as well as the glasses doors. Raikou quickly covered Gau.

"Well I was hoping to visit my Gau," The horned teen flinched at the 'my' part. " though it was a surprise to see him here." He pointed Raikou. "So teach why are you here?"

"To make sure nothing bad happens Gau-kun," he gave the blond a fake smile.

"Well you can leave now." Ryu stepped more into the apartment. "I here for him." Ryu finally had a good look at Gau. Quickly he noticed the new thing about the black hair teen. "Horns?" Gau hid behind Raikou to cover himself. "Horns?" Ryu said it again trying to figure out why Gau had them. "Well," he shrugged it off, "I think they make you look even cuter then before." Gau hated the way the teen said it. Ryu just laugh at his reaction while Raikou was getting more mad.

"Why are you here?" said the pink hair adult.

"If you must know…I here to get my Gau."

"Stop saying that Gau is ours."

"Why? It true."

"Really cause he frighten at you."

"That's just nerves. He will see that I am right for him."

Before Raikou could respond Gau moved out behind him. "Gau?"

"Yes my love?" Ryu smiled wickedly.

"Ryu, I never be yours. Now stop this." Raikou could see there something different in the black hair teen's eyes.

"What are you talking about?"

"I am talking about. This whole twisted illusion of love." Gau voice was becoming irritated.

"Illusion? This is not a simple parlor ticked. I do love you."

"Yeah right!" It finally hit Raikou. Gau's eyes had hatred in them. "You been doing nothing but hurting me and I have enough!"

"Why are you say such hurtful things?"

"Just leave!"

"No."

"I said…" Gau moved one of his arm forward. A dark aura started to surround his body then forces around his hand. His hand made a clutch movement, but quickly released his hand though his hand was no longer a hand, it was now a claw. The claw was white with black tips and very sharp tips. He made the same movement with his other hand, and a second claw appeared. Raikou couldn't believe it; however, now he saw why Gau was able to defeat those fake human. He looked at Gau's face and saw his eyes. The once kind and helpful eyes were replaced with rage and hatred.

It was then Ryu put two and two together. "Of course…" he hit himself on the head, "you are a half demon." He laugh. "That just prefect and make you even more cuter."

Ryu dash forward to the two. Raikou tried to move Gau, but the teen instead he push him back. Ryu made a lance out of lighting and hit Gau on the head. The half demon just smiled and slash at Ryu. The blond moved back before the slash could land though his jacket had claws marks. Raikou noticed how faster Gau was and how weird he was acting. The demon was laughing and moving around like he was just playing around. The teen advance to the other teen. Ryu moved back and shouted, "Now!". Both water then fire blast from the doorway. The attacks hit Gau, who just stood there. The twins entered the room. They expecting to see Gau on the ground and in pain, but the black hair teen shook his head just to get rid of the water.

"Are you done yet?" Gau asked in a high and mighty tone. "Cause I am getting bored and I like to test out something." Gau was about to attack Ryu again when the sound of footsteps running stop him. "There more," his tone was irradiation.

Yoite was the first one at the doorway fallow by the rest. "What?" Yoite looked around, "What is going on here?" Yoite continued to say while looking around some more. He looked at Gau. "Gau?"

"Hi ya Yoite-kunnnn." Gau said in a happy tone. "What brings you here?" His cousin couldn't believe the way the black hair teen was acting.

Raime pushed herself into the apartment. She quickly scan the scene and the room to get a hold of the solution. "Raikou, what's going on?"

"Ryu and his brother are here to play with Gau, so Gau got mad and went demon. Now Gau made his hands into claws that match his horn…" She noticed her brother was having trouble saying the next part, "but…"

"but?" she said hoping what he say next wasn't too bad.

"I think he looks so hot right now." Raime and everyone else fall over expected Gau who blush.

"You are an idiot nii-san!" Raime yelled at her brother.

Raikou laugh a bit, "Also his emotion are out of whack."

"What do you mean out of whack?" Raime asked her brother. Right then Gau jumped on top of Raime's head to get to Raikou. "Hey," she rubbed her head.. "Gau a warning next time."

"So sorrrrryyyy Raime-chan." He landed right in front of Rakou. "Soooo," his attention went to Riakou, "you think I hot?"

Raime smacked her head while Raikou had a surprise face. "Yeah," Raikou smiled at Gau who started to giggle.

"Good cause…" he warpped his arms and locking in his claws together. "I think you hot too." He whispered into Riakou ears. "I think you and me can have nice hot fun." He laugh while blushing.

"You see they are all over the place." He tried to release the demon hold because he was worried what he might do to the half demon. Gau felt Riakou movement and let go. He then grabbed Raikou's hand and started swing it back and forth. "Do any of you…" he looked at the gang, "know why?"

Miharu raised his hand, "It because how the blood was active. The book said that there are three major ways to gain access to the blood though ways have to be fallow by one another. The first way is when the host is in danger and unconstion. During that time the host is unaware of their act." Miharu started to walk to the couple. "Second one is active through rage. During this one the host is more then aware of their action; however, their emotion are out of their control. They attend to be more wild." He stopped right in front of Gau and hit Gau in the head. The half demon responded with an attack back though Miharu made shield. "Last is that the half demon accepted the demon's blood. Though this way aloud the demon's blood over take his human's blood; thus, the blood and body ready for the demon eighteenth birthday. No side effect on this way."

Suddenly lightening was summon, and Gau quickly removed himself from other and aloud it to hit himself. The attack was unaffected to Gau who was now looking at Ryu. "Well then," Gau moved slowly towards Ryu, "ready for round two." Ryu quickly escaped outside, and the demon fallowed him.

"Wait Gau?" Raikou was about to fallow when the twin intervene. "Move!" Raikou voice was steady and stern which cause the twins to be afraid.

"N….no…?" The water user said, "We….we would protect….our brother."

"Really?"

Raime noticed her brother mood and know it wasn't good for the twins. She quickly got in between the twin and Raikou.

"Raime?" Her brother was even stren with her.

"It okay nii-san. We…" the rest of the group run up with where Raime was, "can handle this. Go get 'it' and help Gau. At the moment we can't certain when the blood would wear off. So…" her attention when back to her opponents. "get moving."

Raikou smiled, "Fine by me though handle this fight outside." Raikou ran to his room while the gang chase the twins outside. Once in there he quickly change into his fighting attire (we know the one) and pull out a cover sword. He quickly remove the cloth and the white sheet of the sword was shown. He place the sword where it belong and run out to find his black hair half demon.
