Boku no Meikko wa Yandere deshita Chapter 1

Niece 1 My cute nieces.

Going to Tokyo, for one full year. Despite living alone in a cheap apartment as ever, my life still remains in poverty for some reason.
But to say the least, unlike the time in my parents’ house, my private time is guaranteed!
In those days……it was h.e.l.l. As the youngest child of 5 brothers and sisters, I suffered from the “full of malice” interference from my sisters whenever possible. By the way, my sisters, all 4 of them, are married and have children too, seemingly.
The reason for that 「Seemingly」, is simply because I haven’t met them for several years, I merely don’t know the direct circ.u.mstances. I only heard so over the phone calls coming from my parents occasionally.

ーーBut, that 「seemingly」 just occurred right before my eyes. In addition, forcibly.

The phone call I received from my sisters after several years was beyond shocking for me.
All 4 sisters will go to Tokyo together, and will enjoy (?) the city for about 1 week, is what they said. During that time, they want me to look after each of their child……
Because all of them have children, it is decided that at least 4 kids will stay in my shabby apartment for 1 week!
Of course, there isn’t a slightest chance to refuse. Just like when they told me the business one-sidedly constantly in the past, confirming my intention is unrelated and they hung up their phone. (昔と変わりなく一方的に用件だけ告げると、俺の意思確認など無関係に電話を切ってしまった。)

And, that day is today. They arrive in the morning.
The unwilling me arrange my room lightly, I didn’t do anything and wait for that time despite the holiday.

*pinpon*

They finally came? The one who pushes my room’s intercom has n.o.body besides. That must be my sisters’ child……in other words, my nephew or niece.

*gacha*

The moment the door is opened, 5 little girls vigorously barge in!
「Konnichiwa, onii-chan! Please treat me well for this 1 week!」
「Wrong, it’s not onii-chan, it’s oji-san. Mama said so!」
「Waa, what a small room. Can we stay in such a room for a week?」
「Nee nee, what about washing rice or face? Should I help you every time? I wanted to try doing it alone once!」

Each of them are very lively. Becauce all of them are girls so it seemed like I would be greatly troubled, but the first impression was not bad at all. Besides, to say at least, they are my real nieces who share the same blood. That feeling springs out despite the first meeting.

「Then, shouldn’t you guys go inside firstly?」
While the other 4 invade the inside rudely (*zukazuka*), there is a girl who seems to be docile standing near the entrance. I grasped the hand of that girl without any awareness and led her. Butー

「Onii-chan, for what kind of feeling……did you grasped my hand?」
「huh!?」
「This, do you……like Nana?」
「e!? u, un, Nana-chan?……I like you! I like you, like you, like you very much!」

It’s not serious……it’s truly not serious, I made a forced smile and said so. Really……I really didn’t have any other intention. And yet……why it happened!?

「I……I see. Then we are engaged, right, onii-chan? You must not look at other girls except Nana from now on, okay?」

ーーI was surprised by the suddenness, but isn’t this a little rushed? But sometimes, in TV there are children saying mature things like that.
I didn’t particularly mind it anymore and noon came. I received their light self-introductions and arranged it.
Firstly, the oldest girl, the daughter of my olde
(adsbygoogle = window.adsbygoogle || []).push({});
st sister, Akira-chan. A lively and upfront, and yet the peacemaker for everyone, an oneechan-type of girl. Everything seems to toe the mark unexpectedly if I entrust them to her.
And then the second girl, Asari-chan. It appears that nee-chan wanted to name her Arisa, but she made a mistake and it become Asari. But the person herself seems to be pleased with the present name. Her character is pure and, in a sense, a spoiled child, she holds the spot as the most child-like girl among the girls? (一番幼女らしい幼女といったところか)
Next is the third girl, Yoko-chan. A little cheeky, or rather, she seems like the type who eats without minding what others thought. But the malice can’t be felt, only the innocence.
The fourth girl, Makoto-chan. The one who nicely resembles the familial older sister the most, only at that age but she seems to like cooking and washing. In fact, she is trying make lunch for herself.

AndーMakoto-chan’s imouto is Nana-chan. According to a while ago, she’s the completely unknown number to me, or rather, the “impossible to understand” type.
While other girls is making noise *kyakya*, only Nana-chan sitting cross-legged snuggles up to me and continuously stares at my face.
「W, what’s wrong, Nana-chan? Is there something on my face?」
「Un, there is. Cheating insect-san」 (浮気の虫, refers to someone who already has a partner but has an affair(s) with someone else) 
「ha, hahaha…..cheating insect, huh?」

*pinpon*!

It’s the second intercom today. Certainly, other than these, there isn’t any person visiting today…….Perhaps, my sisters?
When the opposite side of the door is casually opened, an unexpected person is standing there.

「Konnichiwa Saeki-san. Today is the day, right? When your nieces come……tte, ara, seems like they already came, huh? 」
She’s the manager of this apartment, Mashima Reika-san. A refined girl with attractive face and figure, what an ideal girl. (何をとっても理想の女性だ。) Three years older than me……there is completely no problem with that, but unfortunately she’s a married woman.
But, she’s still my 「yearning」, not my object for s.e.xual desire! Absolutely!
In fact, she worked as a nursery school teacher until she got married, she’s also a person who loves children very much. Herself said she wanted to help in various ways when I talked about the matter this time, it’s decided that she would undertake my nieces.
「M, manager-san, thank you! They just came a few minutes ago, but they already make an uproar somehow」
When I was talking to the girl who smiles like an angel and somewhat dere, *tokotoko* Nana-chan came with a pitter-patter (*tokotoko*) and suddenly clung to me.  (女神のような笑みに若干デレて会話していると) 
「Ara, konnichiwa! I’m this apartment’s manager, Mashima Reika. Best regards!」
「Onee-san, konnichiwa. I’m called Nana. Onii-san always is indebted to you」
Nana-chan bows *pekori* with courtesy unlike that of a child girl. (幼女らしからぬ礼儀正しさでペコリとお辞儀をする奈々ちゃん。) Reika-san also sits down and smile sweetly at Nana-chan’s gaze. It’s indeed a peaceful scene.
「a, right! I already prepared everyone’s lunches. Can I come again about 30 minutes later?」
「e? you made lunches for us!? Thank you!」
It’s inspiring to be able to eat Reika-san’s home cooking using the nieces! It’s worth taking care of the girls with just this.
After Reika-san left the entrance, the moment I immerse in the aftertaste of her lingering scent, the nearby Nana-chan stretches her hand.
「a, u, un, Nana-chan, what’s wrong?」
「The onee-san just now, is having a baby right?」
I was surprised! In fact, the current Reika-san is in the middle of her pregnancy. I only knew it shortly because her stomach hasn’t at conspicuous level. (まだおめでたと分かって間もないしお腹もほとんど目立たないレベルだ。) To even see through that!
「It’s indeed what you thought……」
At that moment, Nana-chan face became expressionless, similar to freezing.
「Papa of the child……is not, onii-chan, right?」

I didn’t do anything guilty, but I unintentionally gulped because of the power which is unthinkable for a little girl. (俺にやましいことなど何一つないのだが、幼女とは思えないその迫力に思わず息を呑んだ。) 
「N, no way, Nana-chan! That person is married」
「Fu〜n……but」
At that moment, a light pain runs through my b.u.t.ts.
「wha!」
「Onee-san is married, but has a baby with onii-san, it’s possible right?」
It looks like I’m totally being reproached by a real lover. It’s not the atmosphere that she would forgive even if I answer properly. When I was at a loss for the answer, suddenly Nana-chan slipped out a chuckle.
「It’s just a joke. Because, onii-san is still a doutei-san, right?」
「e!? H, how did you……tte, Nana-chan!?」
Nana-chan who was led by me by the hand began to walk, and the place I was brought to was the toilet.
「I’m sorry for a while ago. As an apology, Nana……will show you」
「S, show me, what!?」
「Uhh, the place the baby comes out」
Nana-chan who smiled dubiously put her hands in her skirt without any embarra.s.sment, quickly took down her cute pantsu smoothly and handed me it.
「Na, Nana-chan!? Do you know what you are doing on your own!? A girl must not do such a thing!?」
「It’s oーkay. Because, Onii-san will marry Nana. Hora, you can touch it」
