Yandere Chisome

Of course, or should I say, naturally, even if my father is gone, me and Chisome's daily life doesn't change at all.

On the contrary, it's a bad way to put it, but because there's no one to get in the way, the one person who was supposed to make Chisome unhappy is now gone.

"I'm the only one left, but... the current me don't have any intention of doing anything bad to Chisome."

Yep, I will never make Chisome sad.

Even I was surprised at how important Chisome was to me, but even in my previous life, I was an only child, so Chisome was my first little sister.

That's why the existence that I have to protect meant something big for me, and if it's a character that one love, anyone would feel the same way as I do.

"And the atmosphere at home is finally getting better."

It's been several months since my father disappeared, and I'm about to graduate from junior high school, but Chisome has also undergone a big change.

This is because her originally beautiful appearance has been further polished, and she is gradually approaching her true appearance as she leaks less of the atmosphere of the monster inside her.

“Hey Rikudou, introduce me to your little sister! I beg of you!”

“Uh-huh, 'want to get to know her better… Seriously, please!!”

“No, I won't. Like as if I'll let some shady guys like you two get a hold of my sister!"

"Today is no good eitherr!!"

"Damn it~!!"

These guys really have some good vibes... I smiled wryly at my friends who are trying to have conversations in their own way.

If the atmosphere that gives fear to instincts like this fades away from Chisome, what remains in her is overwhelming cuteness and beauty that attracts others... Furthermore, Chisome is smart and can be said to be a perfect superhuman.

(Plus, she is also strong.)

Chisome is strong, that is an undeniable fact.

Although I had a not-so-small fear for the first few months, I now have a pretty good relationship with not only Chisome, but also Kuro Chisome.

Sometimes, Chisome gets jealous when she sees Kuro Chisome sneak into my bed and sleeps... I wonder what it is, but its kind of not possible for me to be scared when these two child-like girl cares about me, give off an aura like that anymore.

"Well then. I had something little doing today so see you guys later."

"Aiyo~"

"See you tomorrow~!"

I get a bit hesitant about introducing these guys to Chisome, nevertheless they seem to know that and didn't do anything bothersome about it.

-------

After parting with my friends, I immediately went out into the city.

Usually I go home with Chisome, but today I told her to go home first in the morning.

"Well, I did say 'Congrats' in the morning, so I'm sure she'll already noticed it."

Its a word hint-like, but today is the day to congratulate Chisome.

I rushed to a famous cake shop and received the two types of cakes that I had pre-ordered.

“It’s her fourteenth birthday… I have to celebrate it properly.”

Today is Chisome's birthday.

Rather, she's still 14 years old, isn't she.... a 14-year-old with such a beauty and style, and I have to properly hold off my friend 'cause if not their perception of girls will get warped, like seriously.

Of course, I am also I'm one of them, but... I can endure it because I'm a big brother, and like I said earlier, I want to protect Chisome's heart.

"Wait for me, Chisome! Onii-chan will be back soon!"

I wanted to rush home right away, so I was about make a run for it, but 'wait', a little something got on my mind and I was able to hold back myself.

The cake I bought with great pains would lose its shape, but when it comes to Chisome, I got really restless. I smiled wryly as I realized that.

"I really did become a siscon without realizing it."

Rikudou Taiga, as of now, with great praise, as I wish it is officially given the title siscon. [TL note: the MC is being exaggerating about it.]

When I returned back to home, taking the utmost care not to fall over on the way, I was greeted by Chisome footsteps.

"Welcome back, Onii-chan!"

"Oh! I'm home Chisome."

I also hugged Chisome, who hugged me tightly to my chest.

Every gesture she makes is really cute, and when I look at her, I feel happy every day, and I hope for things to continues this way.

(... Humans are convenient creatures, aren't they.)

[TL note: MC is not being dark, he is simply ruminating over something.]

That's what I thought while stroking Chisome's head.

The former Chisomewas shunned by her surroundings, and even though she was ostracized, the moment she changed like this, people suddenly approached her to try deepen their relationship with her... I won't say its wrong to follow one's instincts to flight over their fear but when its done like that it just make things a bit confusing.

"Onii-chan? Is anything wrong?"

"Nah, it's nothing. Chisome, please expect some good things after dinner. I'm sure you know it already, but spoilers are strictly prohibited."

"Un!"

…… Ah cute, really cute.

After that, time passed quickly, and after dinner, I presented the cakes I had bought to Chisome and Kuro Chisome respectively.

Chisome is strawberry shortcake, and Kuro Chisome is chocolate cake.

"Happy fourteenth birthday to both of you!"

It wasn't just the cake, but it might be an exaggeration, but birthday crackers also rang.

This was also mentioned in the original work, but as a child Chisome never celebrated her birthday or anything like that.

The same also happened to me as Taiga now, but even compared with me, Chisome's circumstances are just way too unhappy.

"uu..... *hick*--!"

"e? Chisome?"

I'm sure this would make her smile, I thought, but instead, Chisome started crying with big tears.

She desperately tried to suppress her voice, but Chisome couldn't hold back her voice and cried as hard as she could.

I knew that perhaps these were not tears of sadness, but tears of joy.

Its because she is also smiling while crying with tears.

"I... I've never been celebrated like this... it makes me so happy..."

"... I see. But it's all fine now, Chisome. From now on, every time Chisome's birthday comes, I'll buy a cake, I will celebrate it like this, again and again."

"un..... un! I love you so much, Onii-chan!!"

And once more, Chisome jumped and hugged me.

When I was stroking Chisome's head just like when I came back, I saw Kuro Chisome staring at the cake in a daze.

(... That's right. For that child, things that happens are just it is what it is.)

Unlike Chisome, Kuro Chisome is not even recognized by ordinary people.

The only people who have probably seen her in the original work are the main character who did get actually killed, and the nameless people who will be killed by Chisome afterwards... In that case, for Kuro Chisome, she must have felt and think this celebration to be unrelated with her.

"Did you really think it had nothing to do with you?"

When I asked that question, Kuro Chisome stared back at me with her eyes wide open.

Her bright red eyes and red patterns sticking to her skin shine eerily, but even that seems to produce the beauty that only she possesses.

She used to be completely naked, but I somehow managed to ask her to create the black-based clothes she's wearing now, which I think makes her look so fresh.

"It just that I'm out of luck to be able to see you like this. But, together with Chisome, you and I will go celebrate. You got that alright?" [TL note: MC is just being sarcastic at the beginning.]

Kuro Chisome is said to never cries, but looking at her like this makes me wonder what it feels like to have eyes that can waver.

Well, let's not think anymore about rude things. I beckoned to Kuro Chisome, and she immediately stood up and walked over to me.

I hugged Kuro Chisome in the same way as Chisome, but her body was still cold as always.

As I hugged my two cute little sisters, I once again promised them that I would be with them from now on.

"... so, um, how did this happen?"

When it was time to go to bed after having cakes, I was carried to Chisome's room by Kuro Chisome.

Just right on the time I was put down on the bed, Chisome with a happy face get into and hugged me again so as not to let me escape.

"I want to sleep with my Onii-chan today. is it no good?"

"Got it. Lets sleep together."

I couldn't turn down my sister's request, so I ended up sleeping with Chisome that day.

It's an indescribable composition of me who entrusts my back to the soft texture of the bed, Chisome who hugs me, and Kuro Chisome who lies down on top of my body.

"I am not heavy am I? is what she's saying."

"Of course not, you are not heavy at all."

Apparently, Kuro Chisome can even control her own weight, and even though she's on top of me, I don't feel any weight.

If the bed was big, we would have been sleeping with me sandwiched between them, but it seems that they are doing it like this because it's too small for three people to sleep.

"Onii-chan... I'm happy."

……I see, I’m happy to hear that too.

Unlike usual, today was the end of a wonderful day where I could fall asleep while staring at my precious little sister's smile.

“…………”

The start of the original work is getting closer and closer, but if Chisomedoesn't despair about the world, then there's no need to worry about it.

In the first place, the main character doesn't have to go to Chisome's route, and even if he did there's no way I'll hand over my precious little sister!!

"... I love you, Onii-chan."

I love you too, so I told her and closed my eyes.
