10th slot is for th final story girl. There used to be 20 slots but I removed.Question because something has been bothering me: that 10th slot for a girl in the character advancement guide is a new lady to unlock or was it always there and i'm too much of an idiot to remember?
Also, the short haired busty woman in the cafe/arcade ArxInvicta mentioned would be the blonde coffe shop attendant or someone else i have not met?
The short hair girl being referred to is the one with anal beads at coffee shop, the one who fucks an air hockey thingy at the arcade and likes polish kielbasa up her bum in the yoga room while cosplaying "I'm stuck with ample room to move" that we see in porn lately.
