Yandere Chisome

"That reminds me"

"Un?"

"What's wrong?"

Brother and sister together at dinner time, that was a nonchalant few words from Mashiro.

"Long ago, there was a battle between Chisome and me isn't it"

"......Ha?"

There was a battle with Chisome? What in the world that means I wonder.

Of course, Chisome was in front of Mashiro's fixed stare, but she nodded as if she were remembering the old days.

"Long ago...... really long ago right. How much does Nii-san know regarding my past?" (Chisome)

“I only know as much from what I've talked to Chisome, you know? Well, I learned a lot from hearing from Chisome after that though.”

I asked Chisome about her family and how long Mashiro had been dwelling within her, but that's about it.

I had never heard of a battle manga-like development in which the two fought in that story, so I was bewildered, and at the same time, it stimulated my Chuuni's heart (Eighth Grade Syndrome), which made me quite curious.

"As far to the first time I gained awareness of things around me, I've talked about Mashiro being there, but when I saw her for the first time, I was naturally surprised you see. And then I was like, who are you? and came be panicked." (Chisome)

"......Well yeah of course it'll become like that."

"Riight~ And then...... Well, it was rather violent, wasn't it." (Chisome)

"Un. It was hard to calm Chisome down at that time." (Mashiro)

The two smiled as if they were yearning for those days.

Maybe something comes to her mind, as Chisome stands up; Mashiro follows suit, and the two face each other in the middle of the living room.

And then――they both held a huge scythe that made one could feel the ominousness.

"Isn't that that time"

The scythes the two wielded were similar in shape, and moreover, that was the scythe that Chisome had previously used to repel and frighten the stalker at that time that followed her.

My eyes were firmly snatched away by the scythe, which also had an ominously cool shape that looked like it would appear in a manga or anime.

"I didn't even know why I had such power dwell within me, so I unconsciously pulled out my scythe and came to slash at her like this right."

"She was impatient at that time. But, Chisome ended up fainting when she exercised her power for the first time that's why."

"......Hou"

The more I hear about it, the more fantastical it is.

Nonetheless, if she had taken one wrong step, that might have turned out to be a terrible result, huh...... As for the course of events after that, the calm Chisome understood everything, but...... I'm really glad nothing happened.

"Don't go make me worried about things I don't know about, sheesh."

"Wawaa"

"......♪♪"

Thinking that I was glad that they were not hurt, I hugged my two little sisters strongly,

As expected, when I approached them like this, the two vanished the scythe. But judging from its appearance, the sharpness seemed to be amazing anyway, and above all, if they were to tell me it was a cursed weapon, it seemed like I would end up nodding......Wonder what would happen if I were to touch it.

“Onii-sama, would you like to try touching it?” (Mashiro)

"e? Is it fine?"

"Isn't it fine? It's not like you'd particularly be cursed, so touching it is fine, you know?" (Chisome)

Hou hou well well......With that being said, taking this also as a good opportunity, I tried picking up the scythe produced by Mashiro.

"......Ooh"

In my frank impression, it was too light, and it was feeling nice and cold.

So much that it almost ended up hallucinating me into thinking as if I were reborn in a fantasy world, the ominousness of this scythe enveloped me.

However, that wasn't a bad feeling; it felt as if I was being enveloped by Chisome or Mashiro.

"I have said it before, but it's finely so sharp, if it were an average large tree, you could cut it down just by stroking it."

"......Hearing that is getting me a little scared."

If I by mistake let it go away from my hand, the moment it touches my flesh, I feel like I'm going to end up being cut off, and I get chills down my spine.

It was becoming scary, so I returned the scythe to Mashiro, but the nice and cold sensation still continued to remain in my hand, and when I stared at it, Chisome grasped my hand.

"Certainly, holding it suddenly is, you will have the stimulation become a little strong, I think. But it's okay Nii-san, that's why don't be so afraid?"

"Ahaha...... I don't mean to be scared though, couldn't help it."

It's a power that has left the human intellect, and a weapon that can easily reap a person's life is, after all, a scary thing.

Such as being stimulated by Chuuni's heart, to lose against curiosity or something......To the point where I can't even think about it now, I ended up being afraid by that cool sensation.

(......Well but, if I think it's the two's power, was it that far, huh)

If I think of it as part of Chisome and Mashiro's power, my fear will also gradually become to disappear.

Chisome finally let go of my hands when my hands stopped trembling, but Mashiro, who was staring at me, looked like she was about to cry at any moment.

"Aah, look, it's okay, Mashiro. Parhaps it looked like to you I was frightened of Mashiro?"

"......Un"

"That's a misunderstanding, so please don't make that face. There there, it's okay now~."

"That's why don't cry," I stroked Mashiro's head.

Perhaps it had an effect; although Mashiro didn't shed any tears, she tightly made a clenched fist in front of her chest and declared.

"I will never let Onii-sama hold that again. I don't want you, to make that face again after all."

"Ahahaa♪ That's fine isn't it, un let's go with that!" (Chisome)

"You're right," I nodded as well.

Of course, it's also true that I don't want the two to have that kind of thing, but undoubtedly, if it's for the sake of protecting, including me, this daily life of ours...... "Surely they'll get their hands on it right," I ended up thinking like that.

(Wait, to think that I worry about such things in this real world, huh...... it's too late for that though)

After that, remembering that we were in the middle of dinner, we resumed eating, and all three of us went to bed and laid down.

"Nee Nii-san, and Mashiro too. This week's Saturday, I want to go to the movies, but."

"Movie, huh. I don't mind at all, you know."

"n, I want to go."

"Then it's decided♪"

Come to think of it, I wasn't too interested in the movie itself, so I didn't go to the cinema that far......As a date, movies are a standard anyway, and it's decided that anywhere you can go with the two of you will be fun.

"It's a love story, but the advertisement gets me curious. It's a stepsiblings' love story you know♪"

"Well well......"

"Want to watch!"

Recently, is addicted not only to dramas but also to rerun movies; Mashiro's bite was terrific.

When I asked the title, I also saw a quick impression on SNS (social networking service), but it seems like there is quite deep content and a love scene or something...... Am I going to watch this together with my lover-cum-little sister...... I don't know; I'm getting very excited.

A few days ago, wonder if you remember the boy who tried to confess to Chisome.

He had fallen in love with Chisome at first sight since the entrance ceremony, and it was after he had made up his mind that one day without fail he would tell her how he felt that day that at last he mustered up his courage.

"......Rikudou-san"

On weekend, while also playing with his friends, he was thinking about Chisome, whom he fell in love with.

She never smiles at boys in the classroom, but she has a comparatively happy smile showing on her face with her female friends, and the smile that can be seen at sudden times has shot through his heart.

"And then you know? Oh Nii-san is so very cool and kind......Me, I love him a lot from the bottom of my heart."

She was going out with her brother; it was a credible specious whispered gossip.

However, since she is always with her brother when she goes to school and when she leaves school, the gossip had before one knew it changed to be the truth.

If it's a real brother and sister, it's fine, but if it's a step, no one can complain......however, even so, it didn't go well because they were siblings, and even I still had a chance; there were many boys who didn't lose hope like so.

"......Still, there should be a chance. If I convey my feelings properly, surely...... I mean, I haven't told her anything yet."

If he sincerely conveys his feelings, it should reach her...... He is reasonably popular with girls, but he held such vain hopes for Chisome.

And today, it will be shattered into pieces.

"That is...... Rikudou-san!?"

Standing ahead of him was Chisome, dressed in plain clothes.

Up until now, he had only seen her in uniform, so he was fascinated by the attire that exposed a lot of skin and suited the flashy her.

"......Alright!"

"It was also fate that we met by chance," he thought, and so he approached Chisome, but...... a man approached Chisome.

Chisome embraces his arm, showing off their affectionate relationship.

That man in particular was Chisome's older brother and her lover, Taiga...... of course, he knew about Taiga as well.

"......I have a better face, right. And my personality too is――"

To have confidence is a good thing, but he also has the character to put others down and himself up.

Even though that was the act of lowering Chisome's impression of him from the start, the fact that he didn't notice it was proof that he was only looking at Chisome.

Parting from his friends, he only walks behind them.

Doing so, Chisome pulled Taiga's arm and disappeared into the back alley; he, while being cautious, peered into the back alley......and opened his eyes wide.

"......ah......aah......-!"

There was a world of only Chisome and Taiga.

Although he is curious about Taiga's appearance, who seemed to be a little perplexed, Taiga responded to the kiss from Chisome to the utmost, and his expression was also kind.

It wasn't just a touching kiss, it was easy to imagine that it was an intense kiss, and moreover, Chisome tightly grasped Taiga's hand and led it to that plump and soft breast.

"..............."

He could no longer let out any words.

Not only does he kiss her, but he...... Chisome's body, which the boys at school greatly seek; to Taiga, who is rubbing her big breasts, to the point he could not put it into words, he held a sense of defeat.

"..............."

On that day, he experienced complete heartbreak.

And he doesn't realize――looking at his back as he leaves away in a daze, a woman gave a strange sneer and said, "serves you right."
