Neco-Arc originated as a joke cat version of Arcueid Brunestud from Type-Moon's Tsukihime visual novel, then became a playable character in the Melty Blood fighting games in the early 2000s. Her chaotic chibi design and nonsense voice lines later spread through Carnival Phantasm clips, fan art and social media edits, turning her into a broader internet meme. Like Tuturu and other short anime voice clips, this death squeak survived because it is instantly recognisable, easy to loop, and works even without knowing the original games.
