Chinen and his nee-chan

I just found this pic. And when i saw this, my reaction is just "eh?? is it real?"
They have the same face type and the hairstyle. Yeah, i know they are siblings, but actually i can say that Saaya nee-chan is a girl version of Chinen Yuuri, or something like that.

This is the pic, she is kawaii ne^^

Really have the same hairstyle deshou? is it Saaya-nee deshou?
