I love my big sister.

That person is a bit…

If you can overlook the fact that she’s a bit crazy, she’s the best wife.

She definitely looks like the ideal bride, doesn’t she, little brother?

Having a sister like this would make life enjoyable.

Good looking, with a great body, able to handle all household chores, sociable, and has good relationships.
This is a luxury to be dissatisfied with.

Does this big sister think it’s okay to marry her little brother?

Oh, really? Then there’s no problem at all!

Scary…

It’s more about the type that violence comes flying at you rather than crazy things…

The fake little sister of the stopper is too much of a ditz to be of any use.

Having a good appearance is bad.

I like it when the person inside is confused.

I’m your big sister, you know!

But it’s nice that you can mimic Hitomi Nabatame’s voice.

This fake sister is way too kind to the ero-game generation of the early 2000s.

I’ve become more like an older sister!

It’s okay to rely on me!

Many younger brothers are deceived because their voice and face are really good, but this person is still really scary…

Big sister, please be a little quieter…

A sister like this suits Knight-kun just fine.

Even though you have such great capacity for acceptance…

It’s not that they are a good match, but this younger brother can keep up with this older sister, which is pretty rare… In other words, they might actually be well-suited for each other…

Taking care of little brother is big sister’s duty!

I really love your voice.

This fake sister is just holding a spare key because she’s properly filled in with the family and everyone around.

I’m officially Yuki-kun’s older sister, so when I’m told that, I can’t really argue because it’s actually true.

It’s fine if the person is interested, but I don’t think there’s any lead at all.

Having parental approval is definitely powerful!

Isn’t it lucky for you, Knight-kun, to have an older sister who can have children?

Do not be deceived, my lord.

I don’t think it’s common to hear someone say, “I really like this kid, so I’m going to date them!”

It’s rather terrifying that there are no obstacles at all except for being insane.

I actually have a girlfriend, you know…

I sensed that you wanted to see me, so I came!

If we’re going to date, let’s do it with my little sister.

In reality, the ability to maintain this unreasonable relationship is not just because of the older sister’s side, but also because the kskn side desires it, so in that sense, it can be said that it is a mutual love.

No matter who Knight-kun marries, it’s the older sister who will welcome him in their new home…

A big sister who is frightening to the level of “what the hell happened in the past?”
Well, what on earth could happen to make it come to this?

The winning strategy for the fake younger sister is to take advantage of the situation while the older sister and the dangerous substance are clashing.

The super big sister who woke up to the coolness of kskn and her own shortcomings…

She has breasts and is a good older sister.

A strong person.

It’s just like a scene from a shonen manga where the hero awakens.

An older sister who doesn’t understand what I’m saying.

Perfect if not for the violence.
However, I feel like I’m being treated as a strong character over there because of the violent elements.

They often resort to violence in the name of discipline.

But you don’t really use violence against Knight-kun, do you, big sister?

Why is my fake older sister getting longer on a Monday morning during the weekday…?

A knight who has become traumatized from being headbutted repeatedly in his childhood.

You hit right away, you shouldn’t use your hands.
Then I’ll use a headbutt!

Riba

The in-game costumes are too sexy.

This older sister strangely doesn’t feel jealous, does she?
I feel that my in-law power is extremely high.

Let’s do it together, okay?

No matter who gets together with kskn, it’s too harsh that my older sister sets the bar high with her household skills…

As long as my little brother’s happiness comes first, it’s okay if he dates someone else and is happy!
But I’ll continue to take care of things around me.

If I don’t have the mental fortitude to learn how to cook my husband’s favorite dishes from my older sister, I won’t be able to marry Knight-kun anyway…

An older sister who can be mean to little kids just to protect her younger brother is invincible.

Even if my little brother gets married, I’ll still live together with him as his older sister.

A suspicious person claiming to be my sister.

The older sister generates a shockwave effect like a “Tōsui-ken” with a headbutt and splits the sea with a slash.

My older sister, who has more classmates from the same school, is showing a different side.

I’m confused by people saying they’re scared.
There are no scary elements, right?

Knight-kun likes his big sister knowing her scary side too.

I can’t help but think that even though I call her “big sister,” she is basically like a mother.

Even if I suddenly gained about five more older sisters, I love my older sister enough to instantly be able to tell which one is the real one, right?

Thanks to my senior, I understand now that even in places where Knight-kun isn’t around, all we talk about is him.
Well, it’s as expected.

Yui-chan is full of excitement and interesting!

Did they come from Atelier Kaguya?

My fake sister from Luna Tower has seriously become a really bad person, and I hate her.

If you don’t know the circumstances, talking about your younger brother is actually a plus, as it makes you a caring older sister.
Well, if you find out the situation, then yeah.

But if this older sister keeps playing games all the time, she’s going to try to make me exercise.

I will do my best to be the older sister.

What will big sister do if little brother gets together with Uni-senpai?

It’s frightening that even though this is so abnormal, the person understands social norms properly and has adapted, yet still behaves abnormally.

High resistance to brainwashing, so excellent.

One of the reasons why betrayal cats are underestimated is the “big sister guard.”

The real fake older sister is too strong, and the real senior Yuni is too weak, so I can’t see a way to win.

Yes! One hour of gaming per day! The continuation will be tomorrow!

Yuu-chan finally managed to invite Knight-kun… but it feels like my sister might tag along.

Is that something that is more seriously disliked than I thought…?

On the contrary, for someone like Yuni-senpai, it might even be easier to be taken care of by my older sister along with Knight-kun, since he doesn’t seem to be good at household chores.

Rather, even after doing whatever I want up to this point, I still seem to be liked by Knight-kun and Rino-chan, so my big sister is amazing…

I thought it was Thumbnail Rinami-chan, but it’s actually a suspicious person claiming to be her older sister.

Is this older sister the type who would be big sister to anyone, or is she the type who only wants to be a big sister to the protagonist?

It’s my big sister’s model kit!

She kind of acts like an older sister to the people around Knight-kun, but since it’s her duty as the older sister of 弟くん, she is the complete opposite of the kind of older sister who treats anyone like family.

This is a famous line that clearly expresses my sister’s stance towards Yuuki-kun…

I like it when it’s naughty, but if we try to date, it seems like I’ll be rejected once because of the sibling setting.

In the swimsuit character story, when choosing a villa, the older sister was searching with the premise of having children with her younger brother, so she is completely consistent.

Because she’s an older sister who is okay with having kids, there are no problems at all.

Until we achieve peace, it is promised that I will remain a modest older sister.
When everything is over and peace has come, it’s better to be prepared.

In other words, seeing kskn as an older sister while also viewing her as a man…

I think she’s among the top class in terms of madness among characters called “false older sisters.”

Being a prime property and being a madman can coexist.
I don’t see this kind of thing often except for this fake older sister, but it can coexist.

I can satisfy my sister, wife, and mother at the same time.

But if you get married, you won’t be my sister anymore.

I mean, it’s crazy to feel jealous of this fake sister, Kokkoro-chan.

Even after getting married, it seems Yuuki-kun still wants to call me “big sister.”

In an event introduction for Kokkoro-chan, I called Shizuru by her first name without honorifics…

I’m scared that this sister would follow me even if she married someone else.

The real appearance is honestly ridiculously cute.

Chloe is thinking about how many babies she can have.

I… think I prefer Rino-chan…

I think a part of the reason why Knight-kun likes older women with big breasts is due to this.

What do you think, Marie?

Even when falling into darkness, what remains unchanged is…

It’s like being distorted or perhaps crazed by the gravity of love…

Perhaps because it’s a big family, Chloe thinks like a mother of many children.

The mysterious power called “big sister power.”
Could it be that you’re an unconscious psychic?

Look, Chiel-kun.
That’s the scheming woman who has already been introduced to the family, thinking about what will happen after she’s become pregnant, leaving us aside.

Yuni-senpai hasn’t even been able to go on a date with Yuuki-senpai, right?
By the way, I went to an amusement park.

There are indeed beings that distort the real world, but the way to notice them is a bit strange…

Unipaisen may be love-brained in reality, but their Astorlum form is more like a complete fool.

I can understand a sensor that can instantly detect when I want to see someone.
I feel a sign that I might want to see you after a while, and before that desire comes, what is it that comes to me…

In the first place, it’s fundamentally wrong since we are not together all the time in the real world.

Even though there’s no sign of that in reality, I wonder why playing with little girls became a kink for me, Uni-chan.
Also, baby play.

For my big sister, the only truth is a world where she can always be by Knight-kun’s side, so in the end, they will get married.

That’s outrageous.

The senior just doesn’t have the courage to break loose in reality.

Even though I’m pretty active at putting away my youkai bag, it seems that’s not enough, is it, senpai?

It would be sad if kskn became a baby, but it’s not a problem if it’s before the nerf.

Thanks to my older sister, Eriko seems relatively reasonable.

After getting permission from kskn’s parents, the older sister was relatively the sensible one…?

There’s no way my sister can marry my brother.

Big sister! Aren’t you always going ahead even though it’s forbidden?
