伽縄 系統
Fluid Mode in the Shibari Style of Yagami Ren
The term refers to the movement of fish in water.
Fluid does not mean "slack." This concept relates to the intensity and tempo of the technique's application.
Since this is an abstract idea, we could spend hours discussing its meaning. However, at its core, it describes an approach based more on responding to the other person’s reactions rather than acting on one's own intentions—more adaptive and, if you will, deeper.
