The TSUKI Project, often associated with the term 'Systemspace,' is a complex internet mystery and subculture that gained notoriety on 4chan and Reddit around 2017. It presented a narrative where our current reality (Life 1) is a simulation composed of 'LCL,' and participants could theoretically migrate their souls to 'Life 2,' a utopian digital cyberpunk world called Systemspace. Led by a figure known as Tsuki, the project utilized cryptic anime-inspired imagery and high-concept technical jargon to create an immersive, if controversial, ARG-like experience. In meme culture, the TSUKI Project is frequently referenced to evoke feelings of digital existentialism, vaporwave-adjacent aesthetics, and the surreal desire to escape reality for a superior virtual plane.
