When it comes to male-female sibling multiple MCs, the only one I can remember off the top of my head is Karlsson's Gambit but there's a few male-female MCs in general I've played
>The East Block
>Whores of Thrones
>Pandora's Box
>Corrupted Paradise
There's definitely more of them that focus mainly on the guy and have occasional segments that shift to the girl's POV.
