Finished up this week's picture - last time was Lily, so here's her "sister", Vivi. Vivi isn't designed from the core to be "cute" like Lily is, so she doesn't have a heavy emphasis on any colors like Lily does with pink. Shaded the white parts with shades of blue so she didn't look as flat with her gray jacket on, though.
As part of the main cast, Lily naturally can be expected to have more to her than meets the eye. This starts to take form as a second persona that takes over for her in times of high stress, with much more assertive behavior. It soon becomes apparent, however, that this is an entirely separate consciousness that resides within her, and she is fiercely protective of Lily. However, Lily comes to fear this entity due to the significantly more aggressive and vindictive actions she takes while in control of her body, and starts shunning her and refusing to allow her to help. Eventually, however, through the magic of PLOT STUFF, Lily makes peace with this alternate self within her, and Vivi is able to manifest in a body of her own, mirroring Lily's appearance like they were twins. From that point forward, the two are inseparable like two sides of a coin.
