Sex hair girl is best girl
But will there be a sister route? And why does she seems so jealous of girlfriends during Arc 1 and 2?
Not really a full route, but sister gets an OVA, your second question is also answered in the OVA.
>Sister only gets a OVA
It better be a long OVA
>And why does she seems so jealous of girlfriends during Arc 1 and 2?
Because she doesn't want her nii-nii date some airhead bitch that rejected him once and treats him like a dog, or violent bitch with issues.
>or violent bitch with issues.
That is no way to talk of best girl
This good girl
But that's the airheaded bitch.
It was the only none lewd picture I had close to hand of a girl in Amagami
