Neko Arc is the comedic cat version of Arcueid from Type-Moon's Tsukihime universe, best known to many fans through the Melty Blood fighting games and online meme culture. Her exaggerated cute appearance and chaotic energy made her a recurring joke character long after her first appearances, especially in fan edits, streams, and short videos. Russian-language creators have also adopted her voice and image for playful reaction clips, using her as shorthand for something cute, mischievous, and unexpectedly funny.
