Chapter 1 "The Emerald Sword."
"Hwaaahnn..."
The boy called Shiki Tohno yawned as he was walked down the streets of Misaki town.
He was a third-year high school student with black hair, somewhat pale skin, and a not precisely muscular constitution. He also wears a pair of round glasses.
"Nii-san, what kind of manners is that?"
The person shooting a glare at him was his little sister Akiha, she was walking by his side.
"I can't help it, waking me up so early on a weekend."
Akiha was a beautiful girl with long black hair, a white headband on top of it, and blue eyes. Her way of talking and acting all reminiscent of her status as a member of a wealthy family.
"Nii-san, you're a member of the Tohno family and should act as such, you should wake up every day at 6- no, 5:30 AM."
"No way..."
Shiki sighed as he looked up. The skies were clear, and the morning sun illuminated it all.
"Such nice weather..."
"Nii-san, you sound like an old man."
"Well, thank you very much."
Brought back to reality by his little sister's voice, he asked her.
"Say... where are we going?"
Akiha shot another powerful glare at him
"I told you didn't i? Or maybe you weren't listening?"
"Uh, no, i- of course i was listening, i just want to uhhhh, confirm what you said, yeah, that's right."
Akiha closed her eyes, inhaled deeply and then let out an exasperated sigh.
"We're going to see an important member of a branch family of the Tohno's. We have some business to take care of."
"Oh, i see... And why do i have to come along?"
"Because like i said before, you're a member of the Tohno family and should act as such, i think you should learn how to deal with that kind of people."
"'That kind of people', you say..."
As the two walked torwards their destination, a certain pair of maids was taking care of the Tohno Mansion.
"Phew, i think it's done."
At the backyard of the mansion, a girl named Hisui, dressed in her typical french maid outfit, was taking care of the plants.
"The wind feels good..."
She felt a soft breeze on her, wich also slightly moved her short red hair.
"Hisui-chan~ !"
"Ah, Nee-san."
The person who called out to her was her twin sister Kohaku, though right now her name was Nanaya.
Nanaya approached her and said.
"There's trouble Hisui-chan! You see, a strong gust of wind came trough the window and-"
"Nee-san, did you by any chance tried to clean the mansion and ended up breaking something?" Said Hisui with a severe tone of voice.
"Guuuuh..."
Hisui sighed.
"Nee-san, i've told you many times, cleaning the mansion it's my job."
"Guuh... I'm sorry."
Seeing Nanaya's painful expression, Hisui felt a little guilty.
"(She must've done that trying to help me.)" She thought.
"Nee-san, i know you want to help as much as possible but please don't push yourself."
"But, i'm your big sister, i should help you with everything i can."
"That's fine, you're always helping me Nee-san."
"Really?"
"Really, so you don't have to do things like that, leave it to me."
"Okay..."
"Now go get whatever you broke and throw it in the trash, i'll think of an excuse to tell Akiha-sama."
"Yes."
Apparently back to her cheerful self, the girl called Nanaya dashed back inside the mansion.
Now alone, Hisui murmured to herself with a slightly melancholic expression.
"That's right, you've helped me more than enough Nee-san, that's why right now i'm the one who should be helping you."
(XXXXX)
Dawn arrived.
Hisui was in the front gate of the mansion waiting for her masters to return.
Sooner than later, they showed up.
"Welcome back, Shiki-sama, Akiha-sama." She said as she bowed deeply.
"Yeah, i'm back."
"I-i'm back Hisui..."
"?"
Hisui was confused. Akiha had a dangerous air around her and Shiki was almost trembling in fear while carrying a huge box.
"Did something happen?" She asked.
"No, everything's fine, right Nii-san~?"
"Y-yes..."
"Well then, let's go inside."
Still confused, she entered the mansion with the others.
Once inside, Akiha said.
"Well then, i'll be in my room, call me when dinner is ready."
"Yes."
As soon as Akiha was out of view, Hisui turned to Shiki and asked him.
"Shiki-sama, if it isn't some sort of secret, could you please explain to me what happened?"
"Uh... How should i say it? Something terrifying happened."
"?"
"There was this guy who apparently was in debt with the Tohno's, he refused to pay, he also called Akiha 'stuck up little bitch' and so Akiha got angry and... did 'that'"
"'That'?"
"It's not something that should be described. Let's just say the guy is gonna have a long trip to the hospital."
"I see, then i can assume what's on the box is not his corpse."
"Why do you assume that!? Anyways, no, it's a sword."
"A sword?"
Hisui's eyes sparkled upon hearing that.
"Yeah, even after doing 'that', Akiha was still pissed at the guy so she stole this sword from him."
"Shiki-sama, you shouldn't say that, she was simply collecting her debt."
"Sure..."
"..."
"You want to see it don't you?"
"Ah, i, um..."
"It's fine, here."
Shiki carefully dropped the box on the floor and opened it.
Inside the box lied a classic japanese katana, however, this one was special due to it's strange color, it was a bright green as if the sword was made out of emeralds.
"How beautiful."
Hisui's eyes were fixiated on the sword, admiring every part of it.
She reached out and grabbed it, taking it closer to her in order to give it a better look.
Meanwhile, Shiki just smiled while looking at her.
Hisui sometimes has shown this sort of fascination torwards cold weapons.
"Isn't that kinda dangerous though?"
"Did you say something Shiki-sama?"
"No, just talking to myself."
"I see, however, this is truly a magnificent blade."
Hisui carefully put the sword back on the box.
"Well, i gotta take this to the storage room, see you later Hisui."
"Shall i take it there for you Shiki-sama?"
"It's fine, i can do at least this much."
Shiki walked torwards the storage room and Hisui went back to do her tasks as a maid.
(XXXXX)
Meanwhile, on a certain hospital of Misaki town.
A man in a black suit was standing in front of a door. He was very tall, kinda muscular, with short black hair.
He opened the door and entered the room.
There was a man lying on a hospital bed.
"Hiro."
The man in black called his name with a powerful voice, which caused an instant reaction.
"I-Izagaya-san!"
Hiro looked at him with fear on his eyes.
"Hiro, you failed me."
"H-huh?!"
"The sword."
"W-what about it?"
"It's not there."
"What are you talking about?"
"The sword I told you to take care for me, it's not in your house."
"T-that's impossible! I-...No, wait, maybe... It can't be."
"Hoh, i see, so you know where it is?"
"I-I'm not totally sure but.. The reason I'm staying on this hospital is because i got beaten up by someone who came to my house to collect a debt."
"I don't care."
"Ma-maybe they took it! Maybe they took the sword!"
"I see, then? Who was it?"
"The Tohnos"
"..."
"Izagaya-san?"
"I'll send a subordinate of mine to bring it back, your job is over, and your life too, enjoy the few hours you have left."
"W-wait! You can't be serious! Izagaya-san! P-please give me another chance!"
"No, you've already proven to me how useless you are. Now if you excuse me."
"Izagaya-san!"
The man named Izagaya left the room.
"Useless, but he is not the main problem right now, I have to get the sword back."
Izagaya left the hospital with a fierce look on his eyes.
(XXXXX)
The next day, Shiki and Hisui were on a date at the amusement park.
"Say Hisui, what should we ride next?"
"Anything you want is fine, Shiki-sama."
"Ahahah... Hisui, can you make me a favor?"
"Yes?"
"Can you stop calling me Shiki-sama? We're dating after all."
"Eh?"
"Just call me Shiki."
"But, that's..."
"It's okay, i just call you Hisui after all, come on, call me Shiki."
"..."
"(Come on, do it.)" Shiki thought as he looked at her with anticipation.
"... Shi..."
"(Yes!)"
"Shi...ki..." Hisui finally said it with her face as red as a tomato.
Shiki was crying out of happiness inside his mind.
"(An angel? Is she an angel? No person on earth can be this cute!)"
"Gehehe..."
"Ummm.."
"Good, then Hisui, from now on call me that!"
"But ,it's embarrassing..."
"You'll get used to it."
"Shiki-sama, you have a weird smile on your face."
"Not Shiki-sama, just Shiki."
"F-fine, Shiki."
"(Gahhhh! So cute!)"
"Good! Let's ride that next! Let's go Hisui!"
Shiki took Hisui's hand and dashed torwards the rollercoster.
"A-ah! Shiki, wait!"
(XXXXX)
Meanwhile, a few meters away.
"Look at them, having such an indecent relationship."
"..."
"Ko-Nanaya, don't you feel the need to tear those two apart the moment you see them?"
"I don't know about that."
"Specially Nii-san, he forced poor Hisui to call him by his name."
"I don't know, Hisui-chan looked kinda happy right now."
"Yes, truly an unforgivable thing."
"Ummm, Akiha-sama?"
"What?"
"Shouldn't we stop this?"
"Huh? What are you talking about?"
"I think it's pretty clear now that those two have a perfectly normal and healthy relationship."
"It's not! It's a relationship that was born out of pure lust and a total lack of romance."
"What are your basis for saying that?"
"Female intuition."
"..."
Nanaya felt dissapointed at her master.
"Still, spying is no good."
"You're my employee, you do what i tell you."
"(Today it was supposed to be my free day though...)"
"Now follow me, we gotta go after them."
"Fine, fine.."
(XXXXX)
In the afternoon, Shiki and Hisui were going back to the mansion while holding hands.
One could easily tell they had fun on their date by the smile on their faces.
"Did you have fun Hisui?"
"Yes, it was truly a wonderful day."
"I see, i'm glad to hear that."
When they arrived the mansion, Nanaya greeted them on a weird way.
"*pant* *pant* W-welcome back, Shiki-san, Hisui-chan."
Nanaya was fatigued and covered in sweat as if she just runned a marathon.
"Ummm, Nanaya-san, are you okay?
"Yeah, i'm perfectly fine, totally, w-why are you asking?"
"Uhhh..."
"A-anyways, i have to prepare dinner, so if you'll excuse me..."
Nanaya dragged herself into the kitchen.
"What was that?"
"I don't know... Is Nee-san really alright?"
Shiki was totally confused while Hisui was worried.
The reason behind Nanaya's behavior is that she was tired after an entire day of following them around with Akiha. 'No breaks allowed when love is involved' is what Akiha told her.
(XXXXX)
It was a hot summer day.
The cicadas were crying.
Hisui was resting in the shade that a big tree in the backyard of the mansion.
"What a nice day... I know, i'll call Shiki-chan, maybe he will come out if tell him how great the weather is."
Hisui got up and headed to the separated building.
When she arrived, she started calling a name as she knocked the door.
"Shiki-chan? Are you there? Come out and play."
There was no response.
This was no surprise to Hisui, the boy who lived here, Shiki Nanaya, always stayed inside this building, isolated from everyone else.
"Shiki-chan? Come on, come out and play with me."
She kept repeating that pattern for like 15 minutes.
"..."
"Shiki...chan?"
Hisui started to get worried.
By this time, Shiki would've normally screamed something like 'leave me alone already!', but this time, there was nothing but utter silence.
"Shiki-chan?! Are you okay?! Shiki-chan!"
She started to pound the door harder and scream louder.
"Shiki-chan! Answer me! Are you okay?!"
Nothing.
No matter how much she screamed, no one answered.
In that moment, Hisui noticed something.
"It's not... locked?"
The door that was normally impossible to open was unlocked.
"..."
Hisui swallowed hard and then opened the door. As soon as she did, a disgusting, metalic odor filled her nose.
And right in front of here eyes, a nightmarish scenery presented itself.
"...Aahh...AAAAAAAAAAAAAAAAAHHHHHHHH!"
In the center of the room was the corpse of the kid called Shiki Nanaya, with blood gushing out of a hole in his chest.
"N-no...Why...What is this...Shiki-chan!"
"You don't remember?"
A girl's voice, with a totally empty, almost mechanical tone, came from her side.
"Huh?..."
Hisui looked in the direction from where the voice was coming.
There was a girl standing there. It was her sister, Kohaku.
"Nee...-san?"
"These are the consequences of your actions."
Kohaku walked torwards the dead body of Shiki Nanaya, she crouched, extended her hand, and carefully caressed his cheeck.
"Poor kid, he died so young, he was such a nice person too, but he's ultimately dead... Do you know why? Hisui-chan?"
"No..."
"It's all because you dragged him out to play with you, it was all your fault."
"You're wrong..."
"Because you forced him to come out."
"No, no, no, no, no!"
"You killed him!"
"YOU'RE WRONG!"
No
Nee-san is right.
I killed Shiki Nanaya.
(XXXXX)
"Ahhhh!"
Hisui woke up with a start, she was sweating and her breathing was out of control.
"Calm down... calm down..."
"(It was just a nightmare...)"
After a while she managed to calm down.
However, the image of the dead boy came back to her head.
"Shiki...*sob* Ghhuu...uuuu..."
Tears started to come out of her eyes.
"Why... am i crying...?...*hick* aaah..."
"(Why did i have to dream something like that?)"
It was around 12 PM and the Tohno mansion was entirely silent except for Hisui's sobbing.
After silently crying for like 5 minutes, Hisui went to the bathroom to wash her face.
"I look terrible..." She said as she looked on a mirror.
Her face looked like she could start crying again at any moment.
After she left the bathroom, she was thinking of going back to her room. However, she ended up on a different location.
"..."
Right in front of the door to Shiki's room.
She wanted to see him.
She wanted to confirm he was alright.
But somehow she couldn't bring herself to knock.
If she knocked on that door, if she called out for Shiki, will the scene of her dream repeat?
She tried to clear her head of such negative thoughts.
"Look at me, getting all worked up about a little nightmare, truly pathetic..." She murmured in a tone of self-mock.
"..."
She grabbed the door handle, turned it, and opened the door.
"..."
In the room, she could see her loved one, Shiki Tohno, calmly sleeping on his bed.
Hisui entered the room and closed the door.
"!"
She instantly realized what she just did as her face got red.
"(W-w-w-w-what am i doing?! Entering a man's room like this! Am i some kind of pervert?!)"
"..."
But she still showed no intention of leaving.
"(But... he is my boyfriend isn't he? I can at least sleep with him, right?)"
"Wha-!"
Hisui was surprised at how indecent her own thoughts sounded, she was barely able to stop herself from screaming.
"(Why am i embarrasing myself like this?!)"
She started walking in circles as she though such things. Hot steam could be seen coming out of her ears.
After a while, she stopped, and looked at Shiki.
His face looked so paceful it was scary.
"Shiki..."
She got closer to him and started caressing his hair slowly.
"You're always trying to protect me... no, to protect everyone, you're a very strong person... that's why..."
"(That's why i want to protect you as well. The person i love.)"
"But, i'm not as strong as you, not physically or emotionally, what can i do?"
Hisui kept thinking about things like that while caressing Shiki's hair.
(XXXXX)
Meanwhile, outside the Tohno Mansion, a man was planning how to get in.
He was tall, seemed to be in his 40-something, had white hair and wore a white coat and black pants.
"Better to find a way to get in and out quickly and unnoticed."
He started analizing the walls surrounding the mansion.
"Got it."
The man jumped from the ground to a tree that was inside the mansion, something that no normal human should be capable of.
"Now, the only thing left is to find the sword, i should avoid every room where i can feel human presence."
(XXXXX)
After around 1 hour of search, the man finally reached the storage room.
"I have the feeling it should be around here."
Then, the man heard footsteps behind him.
"Good evening, isn't it a bit late for visits?" Said Akiha while giving the old man a very sharp glare.
"How did you find me?" Asked the man.
"Honestly, this a rich family's mansion, you'd obviously expect it to be full of cameras and alarms to prevent theft."
"I see, i should've been more careful."
"Indeed. Now, you're looking for something, right?"
"Yes, i'm looking for-"
"I don't really care what you're looking for. You entered my house without permission and tried to steal something. I'm not letting you off the hook easily."
Akiha's hair started to get dyed on a crimson color.
"So be ready for a very painful punishment."
"Tch, looks like i have to take care of this hindrance first."
(XXXXX)
Hisui was about to leave Shiki's room when.
*baaaaaaam*
"What the-?!"
"Uwaaaahh!"
A strong sound came from downstairs.
It was strong enough to wake Shiki up.
"Uh? Hisui? What are you doing here?"
"S-S-S-S-S-S-S-S-Shiki-sama!? I, um, i-"
*baaaaaaam*
Another strong sound.
"A-anyways! Shiki-sama, we must go see what was that!"
"Ah, yes!"
Shiki took his knife Nanatsu-Yoru just in case something dangerous happened and headed downstairs with Hisui.
(XXXXX)
After a while, both were standing in front of the door to the storage room.
"I'm sure the sound came from here... Huh? Shiki-sama?"
Shiki's face looked even more pale than usual.
"This room... is filled with murderous impulse."
It was something he could easily tell after everything he had experienced.
"Hisui, stay back."
Shiki slammed the door open to find...
"A-Akiha!"
A man was strangling his sister Akiha.
Shiki decided not to waste even a second, he took out his knife and slashed at the man.
*swiiishhh*
The man avoided it, but he let Akiha go.
"Akiha! Are you alright?!"
"*cough* *cough* Ghaa... Nii-san! Watch out! He's not a simple human!"
"What?"
Before he even noticed it, the man was standing right in front of him.
"Dissapear."
"Wha-"
The man punched Shiki in the chest with such power he was sent flying back until he crashed into a wall.
"Gaaaaahhhh!"
Shiki felt a sharp pain travel from top to bottom of his body, he barely managed to stay conscious.
"(Such strenght...Akiha is right, he is no normal human... in that case...)"
Taking off his glasses, Shiki revealed his trump card, the eyes who can see the end of everything.
"I-impossible!"
However, Shiki froze in place.
"(The lines on him are so thin i can barely see them!)"
The man walked torwards Shiki, grabbed him by the collar of his shirt and threw him out of the room using his brutal strenght.
"Ghaaaaaa!"
"Nii-san!"
"Shiki-sama!"
Shiki was lying on the floor, almost unable to move due to the pain.
"A-Akiha! Hisui! You two get out of here!"
"What are you saying Nii-san!?"
"The lines on him are way too thin! He's almost impossible to be killed!"
"Shiki-sama..."
Another person arrived the scene, it was Nanaya.
"Whats going on?! Shiki-san! Akiha-sama!"
"Nee-san! Stay back!" Hisui screamed.
Then suddenly, the man walked torwards Hisui.
"Will you get in my way too?" Asked the man.
"Hisui! Run!" Shiki kept screaming.
"Again..." Said Hisui on a weak voice.
"(It's the same as before, everyone is getting hurt while i remain untouched...)"
"I won't accept that!"
Hisui charged into the storage room.
"Idiot, what are you doing!" Yelled Shiki.
"Looks like she will be another hindrance."
The man tried to stop her but before his hands could reach her, his entire body was wrapped in red hairs.
"I won't let you touch my maid!" Said Akiha while doing her best to stop him from moving.
Inside the room, Hisui was looking for something.
"There it is!"
She approached a large box, opened it, and took out the sword that was inside of it.
"Hmmmph!" By doing a simple move, the man was free from Akiha's origami.
Then the man turned his vision torwards Hisui.
"That sword..."
A few meters in front of him was Hisui, pointing the emerald sword she saw the other day at him.
"(It's my turn to protect everyone!)"
"Hisui! What are you doing! I'll try to hold him a little bit longer, you try to escape!"
"No!" Hisui shouted. Something she almost never does.
"I will not let the people i love get hurt while nothing happens to me! Never again!"
"..."
"This time... this time... i'll fight too!"
*Click*
Hisui felt some sort of switch activate inside her brain.
And then...
*shiiiiiiiiiiiiii*
The sword she was holding started to emanate a blinding viridian light and a strong wind started to flow everywhere arounf the room, almost like a tornado.
"Impossible!" Said the man while covering his eyes with his arm.
"What... is happening?"
"The sword!"
After a few seconds the light vanished and the wind stopped, meanwhile Hisui, altough at first glance she looked like she always does, she had changed.
Her eyes, wich were normally a bluish color, were now a bright green. In addition, the look on her face was much sharper. She looked at the man the same way a hunter looks at his prey.
"Prepare yourself!" She shouted.
"Well, this could be a problem." Said the man nervously.
"Hyaaaaa!" Hisui charged at the man, marking the begining of their battle.
-To be continued.
