LF VNs with imoutos that call you aniki

[Kanbe]

Yeh I'm looking for imouto charas that call the protag aniki

Got a problem with my tastes? I'll fite you irl

I was going to say Da Capo 2, but I'm pretty sure they just use Nii-san (Nii-san > Aniki I'll fite u). I'm pretty sure they use Aniki in Umineko, but I don't think that's the kind of VN you're looking for.

That's a rare one... I'm a nii-sama fan myself. The only incidences can think of are where the imouto wasn't a heroine or where she was the imouto of someone other than the protag.

i've seen a few vn where the sisters calls the brother aniki like in cross channel (misato to tomoki) or augment (satsuki to his brother) but not the sister of the MC they always call him oniichan, I think aniki is too formal and that's why is not used in vn, how can you have a love/incest plot if they treat each-other formally xD

Imouto Paradise has one, Rio, the tsundere.

Wait, this was a honey trap, wasn't it?

Isn't aniki the way a gang member addresses a gang leader?  I can't remember a game I've played where I heard a girl call a family member that.

Aniki is actually a 'rough' way of calling someone their older brother.  In the case of yakuza or a street gang, it is usually a weak guy calling a stronger guy that.  In families, it is usually the guys who call older male siblings that, not the girls.  Generally speaking, tomboy sisters are the ones who call  their older brothers that, and the imouto image preferred by most otakus doesn't really fit that.

Sorry but I just have to butt in and say nii-nii beats both of those any day of the week. Come at be bruh!
