*Vigne can be said to be the purest character in the group. She is kind, friendly, polite, responsible, helpful, and diligent. Often, she acts like the eldest sister of the group with Raphi usually assisting her more than Gab and Satania. As a result of her ideal character, Vigne is the opposite of Gab. She can be deemed as a "Fallen Demon". Many people mistake her for an angel instead of a demon.

Vigne has a solemn and mature persona, which makes her fit as a leader for the group. Although it was Gab who brought them together, Vigne manages to keep them together so that they remain good friends and stop all potential trouble that could split them.

Vigne is also well disciplined; she is very tidy as her room is elegant and she often cleans Gab's as well. She is also very kind and emphatic, as she is the one who often invites Satania to join the group to do things together. Like the others, Vigne is incredibly loyal to her friends.

Despite so, Vigne is not without her flaws, as she is quite temperamental when she gets annoyed too much, although her patience is admirable since handling both Gab and Satania requires incredible patience. She becomes cruel enough once she loses her temper, using intimidation and even harsh punishments to keep things straight; on one instance she even used her demon form to stop Gab and Satania from ruining their Christmas celebration.

Her serious nature also made her intolerant of being treated like a toy, like when Satania said she is a slave/follower, Vigne immediately retaliate by not giving her the clothes she needs. Overall, her negative traits are far overshadowed by her positive qualities, making her the straight character of the series.* " I'm Vignette April."
