This is Vivi. This is actually the 3rd design, looking a bit more human. The first design was mostly based off Vibri from an old PS1 game called Vib-Ribbon, and her second design is a transition to the current and the 1st design. There's an unreleased sketch that Viv's in between the second and 3rd design, and only key difference is that she has an inverted zipper on her 'dress'(which is very odd and impractical to jackets, everywhere).
