As far as I can tell Bisca's insignia has never been shown. Not in pre-timeskip, post-timeskip 또는 even her Edolas counterpart. Sorry. I have looked through her appearances, and even in a bikini 또는 in the bath scene in the OAD "Welcome to Fairy Hills", I haven't spotted her insignia. It's hard to find an area of her body that hasn't been shown. My guesses would either be on the back of her neck (always covered 의해 her hair), the soles of her feet 또는 her arse. As for the colour, it could be anything. But I like to think she has a dark red insignia.
