yea She's a locked character for Ren only , u can see who they "prefer" when u go to the main menu , click on the flower(?) on the top right
go to characters
on the bottom right , where it says "on" , click on it , on each character you'll see a red flower and a blue one(red for Inei and blue for Ren).
if u see that a character has both flowers , it means that character is an LI unlocked for both personalities(Maeda) , if u only see one flower ,it means that character is an LI locked to 1 of them
