Sumi and Virtuoso do not get along, to say the least. In fact, Sumi absolutely loathes, and the fact that the feeling isn't mutual only causes further irritation. Their views on art are too incompatible. In Sumi's view, her Idolon undisciplined, unfocused, and her work is comparable to a child's scribbles. To the The Virtuoso, Sumi is simply to high strung. Lofty concepts and complicated techniques are just a distraction for her.
Virtuoso uses what little power she has in the real world for creative endeavors, ranging from drawing on walls to making unwanted alterations to her club's members works. Finding a canvas ruined by her or even just something scribbled on a sheet of paper drives Sumi up a wall, and she doesn't hesitate to destroy them. Even worse if someone else notices first, but she tends to lash out when others dare to criticize them.

The Virtuoso's movements are acrobatic and floaty, and her actions dramatic. It's more similar to a kind of performance than a true method to combat. The longer it goes on, and the more those around her buy into it, the greater the extent to which the battle is shaped by her.
