Author note: Hello, this is Rainbowbutterfly16 here. I started to re-write the whole chapters since the pace is a bit fast. As I read my story again, I agree with you readers. The whole story is not going to much different from previous version but I would change some and settings.

Also, if anyone is interest to help me about the grammar that I and my beta missed, please give me a hand. I would like to use extra help and I would be grateful.

The timeline will be Rikuo defeated Kyoto's youkais and inherited leader's title from Nurarihyon.

Also, the Japanese language will be just normal while other language will be italic like this along the thinking.

Waring: some foul language, OCs, violence, a bit AU, and some grammar mistakes.

Ch. 1 Crimson Butterflies

The night has fallen to Ukiyoe Town. It was so deep that even the street lights could not able to shine upon the shadow behind. Mankind technology had greatly changed since so much time ago. However, the darkness was still near to mankind. Some of human would believe they are still exited next to humans. Those beings… they are called…youkais. Youkais needed 'fear' from humans to exist and stay strong. When the more youkais are gathered they could form Hyakki Yako, it literally meant 'hundreds of youkais' or parade of demons. They were hiding from light but sat tight next to it. Only few humans could notice their presence and if they were lucky. Also, if they were luckier enough then they could run while they still breathe.

Ah, it looked like a human got involved into a fight; between youkais. This fight was currently was holding at one of dark streets in Ukiyoe Town.

The young woman with white long hair that put inside of her white beret was standing in middle of youkais. A crimson butterfly, its color would resemble blood, was floating next to her while that woman was holding the long sword that was very identical to that color. She pushed her right foot an inch to front, readying for the attack. At the same time, she adjusted her holding onto and gripped a bit loosely yet strong.

'They should have attack us from behind. If, they wanted the ambush, ambush.'

Surprisingly, the crimson butterfly said, more likely talked to young woman's mind. Its voice was like a girl at early teen ages. Young woman scoffed half heartily at that statement. Her attitude told that she knew this situation was eventually happened to them.

"They are youkais; beings that are strong than humans. I guess they thought they could take me down easily."

Despite what she said, the youkais would not dare to come closer to get her. Next to her feet, some corpses of youkais were lying on there in dead state. These corpses had deep injuries which looked like they were cut by sharp blade. After remaining of youkais saw this human took down them easily, they wouldn't dare to move their feet to their target.

The butterfly made sound but it was sighed like human.

'Well, you got us anyway,anyway. They are not gonna go back alive, alive. How are you doing big bro?' The butterfly asked as if it was speaking other being beside her. However, there was no one before them and swarm of youkais. But, the voice came back anyway.

'I'm fine, Ho. But stay cautious. I don't want you bump to any of them so I won't worry about you.' This voice sounded like full grown guy; early twenty ages precisely. Also, it sounded playful but mischievous. As result….

'Hmm! Let see if you are fine after Yuuyea [Yuu-Yea] swing you so many times!' The butterfly, Ho, let out anger while if flew around young woman, named Yuuyea, furiously. When she saw Ho lost its cool, she tried to calm it down.

"Ju, don't being meanie to your younger sister. Ho, calm down okay? How am.."

As she looked at her butterfly, one of youkais saw this opening and it launched its attack to her. They followed that movement along with the victorious face with sharp claws that could tear down thin steel sheet. This almost seemed like a finished battle. Almost. To Them.

Yuuyea crouched to down quickly and no time to waste, slashed the arm that almost got her back. Blood pumped out from youkais' injured arm and soaked on the street. It let out agonized and painful scream. Its scream didn't last long because she thrust that youkai's stomach with her blade. Blood oozed then made a sick sound as the blade pulled out from it. Then youkai fell down on the ground by gravity force. Some blood got on Yuuyea's clothes but it disappeared instantly not even leaving the stain.

'Yuuyea! Don't move so big, big around! I can't take those blood out every, every time~!'Ho dodged rat look like youkai's hands while scolding its master. 'I agree with her. You are really working here that is so not girl.' Ju scolded Yuuyea as well, in more annoyed and playful way than Ho said. Yuuyea practically felt a sweat ran down on her head animatingly.

Dog youkai spat words like it didn't expect this human was very resistance. Well, there was one said - don't judge the book by its cover- but still this was different what they told to youkais that attacked her. "What the hell! We didn't hear that this human could take down us! We…are not any just youkais!"

Yuuyea stopped for a moment to swing around her blade but she reposed her composure as taking down more enemies. "So you guys are from them…Well, then I should make sure you guys won't return to leak the information." She said harshly and kicked the youkai from behind her. She wore white heels that are not tall as others but still these are heels so delivered damage that made youkai to fly out and smacked on the ground with impact. It looked like she kicked so hard because there was crack sound when it fell.

When a bug youkai saw how its fellows were falling one by one on hands of human, it tried to make run for it. It tried.

"I thought I made clear that." The cold voice whispered behind it then a slash sound followed next. "I can't let you guys tell them about me." More blood split on the ground, made grey color street into crimson red.

Yuuyea looked around her surrounding for a moment before she left the scene. Youkais corpses that tried to attack her were dead, lying on the street. She gathered her hands so she could pray for them. "I'm very sorry that you youkais are involved in this…"

She didn't hold her blade at the moment but two buttons were on her white beret side by side. The buttons had black background color and one crimson butterfly on each. Also, there was no crimson butterfly on her side right now. However, two voices still made a way through to the scene.

'Yuuyea, let's go, go! We need to go before the youkais from this town see us!'

'I would say we don't look here for problem like we did now. I can still move but I don't think your body can still handle one more fight.'

As these beings said their voices, she couldn't help but laughed abit. Ho was worried about her literally while Ju said the way someone could be irritated but only close friend could see through it. Only close friend. "Alright, we are leaving even you guys are not pushy about it."

Just when she about to leave, more youkais were showed up. What a good timing. Why the world would make this timing just as someone left the scene? Well, without this timing there would be no progress on story.

Yuuyea sighed tiredly but youkais already surrounded her. There was no escape for her, or was it? One of youkais stepped out and saw the scene with surprised look. It noticed these youkais were not Nura Gumi's youkais…then these attacked this human? Even so, how can this human alive even she didn't look like onmyouji.

"Please. Move. Aside." Her green iris held no harm to youkais but she held the intention to attack them when they would try to attack her.

The youkais flinched to hear as her cold voice makes them to shiver down their spines. How can this little woman make them to act like this? However, they didn't want to move because the woman was making ruckus in their territory, Nura Gumi's territory.

Nura Gumi was like a giant yakuza organization that made of many groups of youkais that ruled around Kanto region. The first generation, Nurarihyon wanted to have a friend that he wanted to talk with someone. As he gathered youkais-whom they were afraid of him or wanted to have a chance to After the time, his Hyakki Yako got huge enough to look over the region and made mansion in Edo at the time it was start of new era as still lasting for 400 years until these nowadays.

Okay, lets back to the story.

Yuuyea sighed as she crossed her arms front of her chest. She clearly had tired face but her eyes didn't waver one bit. "I'm kind of busy here. So can you please move so I can go?"

"Is that why you make ruckus in our territory?!" One youkai mustered its courage to ask this woman. She didn't ignore that question.

"I have no intention to disturb in here. I was just trying to be…going." She put more pressure on word 'going.' She thought that she needs to go somewhere as soon as she could. No more fight tonight if that could be avoid as possible.

After that words left from Yuuyea's lips, she gathered her left over strength as much as possible then jumped high over. There was emergency ladder on the building where she jumped so she landed on it. The rebound made her to wince but she stood up quickly and went up to building in quick pace.

Youkais were still dazed how that human made high jump and went back to reality after they heard what she said.

"I hope I won't meet you youkais from this town next time in bad situation! Good day!" Yuuyea disappeared as she made her way on the open roof. Nura Gumi's youkais sweated when they realized what she said to them. "Did she said…good day to us? The human…to youkais?"

One youkais that seemed like friend to that youkai asked just shrugged its shoulders. Yes, it was so unusual that human said good day to youkais….yup…

"I'm going to be late!"

The chocolate haired boy ran as he holds his breakfast, the bread, with his teeth and chanted something like 'please I make it to school' while he was dashing.

He was Rikuo Nura, a normal middle student to everyone but he was not normal at all. He was quarter youkai and Sandaime of Nur Gumi. In fact, he will turn into his youkai form when the night falls. Yesterday night, he got report unknown human that made ruckus in part of his territory. The human looked like uninjured but there was corpses of youkais that were not Nura Gumi's. He wondered what could that human could possibly have business to youkais and made it alive unless she was onmyoji or such. Rikuo made note that he will find out later tonight.

As he was about turn around the corner, he bumped to someone and almost fell on the ground. The person who got bumped grabbed Rikuo's hand so he wouldn't fell.

"Are you okay?" The voice was girl, no, more like mature to be girl but young to call full woman.

'Huh?' Rikuo wondered when he heard that voice because the voice didn't sound much natural. Must be foreigner. He raised his eyes to see who it was and froze on his spot. The young woman had white hair that put hidden under her white beret with two buttons carved with crimson butterflies on each of them. She wore white long top clothes with blue short skirt, black stocking and white fur boot. Moreover, she had a beautiful face that captured his attention with first look. Her eyes had clear looking; if someone asked him about what got his eyes most of from her looks.

For a moment, when Rikuo saw her face, he saw a blurry vision next to her face. He couldn't make out how the face looked like but that blurry face had long hair. Also, he felt that he saw that face somewhere but he couldn't think. Plus, this woman, he had a feeling that he met her but he just put that other side. Must be still dazed by less sleep he had tonight been getting on him.

The young woman giggled a bit when she noticed how Rikuo was in deep thoughts while looking at her. He looked kinda cute to her. A well said statement, well said.

"You were in such hurry. Shouldn't you go?"

"Hah? Uwhaaa! I'm very sorry! Excuse me!" Rikuo got back to the fact that he was late to his school and dashed to the school like running away from the danger. The young woman, Yuuyea smiled a bit as the boy disappeared from her sight.

As she was about on her way, she noticed something on the ground. It was name tag. Probably it belonged to that boy she just got bumped into. She picked it up and examined the name.

"Nura…Rikuo…"She said slowly as tried to say it right.

Yuuyea wanted to return this to boy but she didn't know where that boy could live. Of course, she was outsider in this town and didn't know which school that boy might be attended.

"Looks like I need to hold onto this for now."

The school dismissed after all periods ended. Rikuo and his friends were walking back to their homes. Kiyotsugu was babbly about new story that he got from online last night.

"Lately, people are seeing the ghosts these days. It's probably some youkai's doing! A youkai that controls the spirit! People don't know what might be this youkai. It could be a new generation youkai. I'm so excited that I want to meet this."

Rikuo couldn't help but laugh and sweat dropped at the same time. Kiyotsugu sometime got carried away and could careless his safety and that youkai could attack him. But the ghosts huh? Maybe that human he got report from could involve with this. As Rikuo wondered into his deep thoughts, Tsurara Oikawa tried to get attention by talking with him.

"Waka(Young master), you look dazed or something. Did something happen this morning?"

"Huh?" Thanks to that Tsurara's question, Rikuo remembered that woman's face and blushed a bit what he thought as he looked her face. "Oh, it's nothing." He managed to not stammer so he won't raise her suspect to him. "Is that so? Any way Waka, what do you want for this dinner?" Apparently, he did well.

Rikuo and Tsurara said good bye to their friends and returned to the Nura Gumi's mansion saftely. The youkais dashed to the main door and greeted their leader.

"Welcome back, Sandaime!"

"How was your day, Rikuo-sama?"

"Oi, Rikuo-sama's back!"

"Hello, guys." Rikuo also greeted them as he smiled back to them. He went back to his room and changed his uniform to night kimono. As the sun set down, his feature changed as well. His chocolate colored with black bottom hair now turned into the top half of his hair is white while the bottom half of his hair is black as his long hair stood out in back of the head. His brown eyes became crimson-red eyes as well. He wore black kimono with blue haoi jacket.

Rikuo was sitting on his favorite spot of sakura(cherry) tree that stood in the main mansion's garden and was drinking the sake before he left for his works. He was thinking about that woman who looked kind of interesting. Sure she was beautiful but what was that face he saw along with her? Was it just his imagination? Rikuo couldn't help but went to in his deep thoughts. As the result, the sake in his cup didn't gone for a long time.

"What could it be?" He murmured as he was taking sip of his sake,

"What do you mean what could it be?" Rikuo chocked out and coughed his good sake as he glared back to the source that caused it. The Nurarihyon, his old grandfather was smirking as he took a breath of his pipe.

"Jiji (gramps – in a rude way)…" Rikuo was giving death glare to his grandfather but his grandfather ignored that like nothing.

"You seem lost in your thoughts so I thought you might need this old man." Nurarihyon teased his grandson as he smirked mischievously to him. Sometimes he could be serious or mischievous at the same time. It was hard to read his thoughts all the time. After all, He was the first commander of Nura Gumi and lord of Night Parade. It won't be easy to win against him.

Rikuo almost wanted to slap his grandfather to make him fun of him but he jumped down and landed gracefully on the ground. "I don't need your help, gramps."

"Oh, such harsh words. Anyway, shouldn't you go look for this human that made ruckus in our territory?"

"I will when I finish my drinking." Rikuo crossed his arms and drifted his eyes to somewhere else. As Nurarihyon saw his grandson attitude, he couldn't help but snickered visibly to annoy Rikuo.

"You sure need to grow up."

"Why you…"

"Rikuo-sama!"

Kubinashi jumped onto their conversation in hurry as he ran to their side. Also, Kurotabo and Aotabo joined him from behind. Rikuo raised his one of brow and asked him with his cool voice.

"What's wrong, Kubinashi?"

"The outsider from yesterday! She returned again but this time in other street!"

"Well, well. Save you some trouble, didn't she?" Nurarihyon snickered as he looked his grandson. Rikuo gave his confident smile as he gave his ordered to his subordinates.

"Then, what are you waiting for? Let's go and teach some manner."

"Yes!" The three of his subordinates gave their answer as they followed their leader's back.

The weak girl covered in blood tried to ran away from Yuuyea who was chasing that girl with all her might. She shouted loudly to that girl.

"Come back here right now!"

'Yuuyea, I don't think no one would listen to stop words when he or she being chased.'

"You don't have to remind me that, Ju."

Ho tried to keep its pace with its master as possible as it could. 'I can't believe we let that escape while we were fighting, fighting!'

Ju just snickered followed by its sister, 'Then we just need to catch it.'

"Guys, let's focus on the task please."

Yuuyea swung her blade in middle of air and swarm of crimson butterflies chased down to that girl. Just when these butterflies about to touch that girl, someone cut those butterflies with one swing. She stopped her track and tried to catch her breath from the running. She looked up to see what idiot saved that thing and noticed who was responsible about it.

"Who are you?!"

"I don't know who you are but don't make such ruckus in our territory." The cool voice rang from the darkness as the figure stepped out from it. The figure was Rikuo in his night form. Behind of him, the girl that she chased down stood with his subordinates.

Just when Rikuo looked at Yuuyea, his eyes widen in surprise. It was the young woman that he got bumped in this morning. Of course Yuuyea didn't know Rikuo in his current form that same as cute and innocent boy she just ran into this morning.

"It's you."

"Huh..?" Yuuyea tilted her head aside when Rikuo said something she didn't understand. When he tried to ask to her, she noticed something and yelled to him, no, his subordinates. "Get away from that, now!"

"What..?"

In matter of sec, the girl's body blew in tiny pieces and big bug looking like ayakashi showed up. It sent off Rikuo's subordinates who were surprised to see this with its huge claws. Then when it was about attack Rikuo, Yuuyea jumped into its way and slashed its claw. However, one of its claws managed to pierce her body.

"Ugh!" She coughed the blood and fell down to a ground a bit.

Rikuo reacted quickly and slashed ayakashi in one swing. But ayakashi managed to avoid that in shortest of time and ran away. When Yuuyea saw it was getting away, she held on to injury with enough force and followed it.

Tsurara ran to her master side quickly with concered face. "Rikuo-sama, are you alright?"

"Yes, I'm fine. But…I'm kind of worried about that human." Rikuo looked at the way where that ayakashi and Yuuyea disappeared into. He couldn't shake that feeling he own on her. Also, he always wanted to protect humans from threatening youkais and ayakashis. So…

"I'm going to follow her. Kubinashi, Kurotabo and Aotabo. You guys go to the side where they came from. There could be something left on there. Tsurara, you follow me." After Rikuo's command, his loyaful subordinates said 'yes' to him. Tsurara would be a loud one because she was happy that Rikuo let her tag along with him.

Rikuo stepped forward more while he looked around in stealth mode. Tsurara was on her guard as well so she can protect him with her best. She didn't like how Yuuyea protected Rikuo in that way. Ah…such a childish to jealous about that. Tsurara was kind of competitive when other girls tried to gain Rikuo's attention. For example, his friend, Kana was good example about it. There would be rival air around them when Rikuo was involved.

…It was happening so soon. That bug ayakashi gripped Rikuo from behind with full speed. Tsurara was taken by surprise that and other. It had wings! The next coming was it flew away while gripping Rikuo with its hand.

"RIKUO-SAMA!" She couldn't help but yelled to the sky. "I can't believe I let that happen! But…Rikuo-sama could dodge that…Why?" She asked to herself as titled her head with questionable face.

…

…

The bug ayakashi laughed hideous way. It got its target in his foot and obstacle at his hand. It will give the target to them and eat this youkai. He looked so yummy to him. However, while Yuuyea was careful about not attack this youkai, Rikuo smirked with cocky face.

"I got you now you idiot."

He pulled out his katana from the sheath and pierced its chest. It screamed painfully and let go off them. Yuuyea screamed as well because she and Rikuo were falling from top! What was that youkai thinking?! She almost wanted to hit his head for being aggressive. The ayakashi was flying in low attitude but still it would be hurt to smack onto ground. A huge one.

Rikuo quickly gripped and pulled her shoulders to his chest with firm grips. Then he tapped onto side by side buildings to less the impact when they arrived on the ground. Just as he was about to arrive safely, that ayakashi shot sharp objects on them. It grazed on Rikuo's one of shoulder but he lost his balance and fell onto dark alley.

Ayakashi saw how they disappeared; it roared disgust and decided to head back. It needed to tend it wounds. Also, if it failed to bring its target then it had to tell target's whereabouts to them. After the injury was taken care of; it won't go back yet. It pressed its chest with its hand so the body won't lose more blood.

While that bug thing was retreating, Rikuo and Yuuyea were safe because they were bumped on the thrown out mattress. So thery were in the dumster area but it was good that they were safe. Except that Rikuo lost his conscience for a moment. When Yuuyea saw ayakashi was leaving, she couldn't help but slammed on the mattress.

"Great, I have to keep on the low file more here…"

Ho's voice made out from nowhere like it did every day in a certain state. 'Huff! I think this youkai is the one that caused it, it! Yuuyea, let's leave, leave here!' When it nagged in annoyed tone, she hushed it. "Ho, you are being hysteric here. Please be patient with me, okay?"

'….' There was no reply. It must be angry enough to shut its mouth. Ju was chuckling how its sister to be this annoyed. It planned to tease Ho later how she was being such a spoiled child.

Yuuyea examined Rikuo for a second before she decided what to do. She could just left here since he was youkai that control this area right? He said so; it won't be problematic for him to go back his home. However, this youkai gripped her and took most of damage of landing. When they were just about land on mattress, Rikuo turned around his back on mattress while holding tight her on his top. Also, he was injured from the attack. It needed to be tending no matter how small it was.

"Well, I already decided with what to do next." After that, Yuuyea got up.

A/N: Okay, I will stop for here now. I don't know when there is going to be next one but I will try to type it down. Thanks readers who read this and showed some love to this story. I really appreciate you readers.
