Vivi x Nico Robin! (Patreon)

Robin caught Vivi as a part of her mission, while she was still working on Crocodile. However, instead of capturing the Princess, she decided to test her inner strength and see if the blue haired girl is someone Luffy can trust. Vivi, on the other hand, was nervous at first, but started enjoying their "battle" way more at the end, realizing, that Robin was just testing her!
