Neko Arc is a joke version of Arcueid Brunestud, the heroine of Type-Moon's Tsukihime visual novel, and she became widely known through the Melty Blood fighting games, where her exaggerated, cat-like behaviour stood out from the more serious cast. Fans turned that contrast into a lasting meme, using her in absurd edits, parody videos and reaction clips across YouTube and TikTok. Because the character is instantly recognisable to anime fans yet funny even out of context, short Neko Arc clips remain a quick shorthand for chaotic, unserious humour.
