Tettaisen (Withdrawal Line) is a design fiction by Synflux and Itsuki Tsukui. It proposes a new image of people living in developed countries in the aftermath of population contraction and rural decline. Such people have left urban areas, which no longer support creativity, and headed for remoter regions. Genetic engineering ha turned people into post-homo sapiens, what we here call kemomo (beasts). In the Exhibition we offer the experience of a Diegetic Collection of plural realities, real and virtual. Kemono skins may be obtained with NFT, and worn in the metaverse, from the WORTH platform (www.worth.ooo) organized by Synflux.
