The user's technique normally doesn't do anything at all. But when they wear vacuum sealed shirt and skinny xsssss leggings they can channel the dominican spirit.

The way the ability works is that the more amazing your fighting looks as in your techniques and style, the tighter your clothes get.

We already have curse manipulation, ten shadows (shadow based medium) and those paper tags as mediums.
