x0o0x_ (pronounced typically as 'Zekkusu') is an anonymous Japanese musical artist and animator known for their hauntingly beautiful, monochrome, and glitchy visual style. The character designs often feature sketchy, distorted figures that evoke a sense of mystery and existential dread. These visuals became popular on social media platforms like TikTok and Twitter, where they are used to represent niche internet aesthetics, 'vibe checks,' or to express complex, unnamable emotions. As a meme, the x0o0x_ template serves as a canvas for the cryptic, the deep, and the experimental, often appealing to fans of the Vocaloid and Utaite subcultures who appreciate the artist's signature dark, atmospheric storytelling.
