NEXUS is created by SATSUKI and it is the metallic version of his emblem tattoo that is inked on his right hand.
The meaning behind this tattoo and also that pendant is that the hand that holds the microphone when he sings, or creates from lyrics, to accessories or drawings,
This hand and therefore this image is the bond, what connects SATSUKI to his audience and the public.
It also represent the bond to his personal connection with the world, nature and the elements of sky and moon that give him their energy.
Deep and meaningful symbol for the artist.
