The term "hikikomori" (loosely translated as "separation", "an alienated being") is applied in relation to the civilisational malaise common among Japanese youth. It is similar to depression. The sufferer seeks isolation from the world and does not leave his room. The work is a metaphorical record of the consecutive stages of the dissolution of the human psyche. The narrative unfolds in the claustrophobic space of blocks of flats, which is slowly taken over by the mysterious black substance. The "dark matter" on the one hand causes the destruction of ordinary objects, and on the other keeps our daily reality in one piece.
