I am really interested in OP females in fact they were the reason from the very beginning on why i watched the series. But i don't like them all.
Personally, the best for me is Robin. Sexy, smart, beautiful and strong. I pity her too for not growing up with a mother and having her hometown destroyed but still she managed to live even w/ TOO MUCH suffering. It's her loyalty to the straw hats that makes her loved.
The worst for me is Shirahoshi because she's a crybaby. I HATE CRYBABIES.
so who's the best and the worst for you?
