Kuroko is like an existence of darkness. Kurokos support actors wear leotards, and bring them on their position when they are in the play. In Taipan art, Kurokos must respect differently abled people as artists, and be careful of them. Kurokos do their works silently, safely and accurately. They exist like they don't exist supporting actors at the backstage.

Using black curtain and wearing black clothes, they become a medium between onstage offstage. Because there is a new world of actors' body expression on the stage, and Audience have an artistic experience of Beauty. 

People who were disabled, become actors and artists having identity as a differently abled artist. Kurokos support actors become artists themselves.

;;lby wearing leotards, Kuroko tells an actor, 'From now on, you're an artist.'

outside of onstage, they are disabled people but on stage, they act showing their bodies.

Through taihen art, Disabled people and non-disabled people who were their helpers in common, become artists and Kuroko. There have different roles, it means there in different relationship with extraordinary understanding of human in taihen art.
