Neco Arc is a cat-like parody of Arcueid Brunestud from Type-Moon's Tsukihime and the Melty Blood fighting games, and she became a breakout internet meme for her exaggerated expressions and nonsense vocalisations. Short clips of her voice spread through YouTube edits, TikTok videos and Discord soundboards, where fans reuse them as absurd reactions rather than as dialogue from the games. This stretched 'gudaniiuiuiu' line fits that same pattern as other goofy ahh sounds, staying popular because it is instantly recognisable, easy to drop into any silly moment, and tied to a character many anime fans already know.

Short Neco Arc voice clip saying 'gudaniiuiuiu' in a playful, stretched tone. A meme sound effect from the Tsukihime cat character, used for anime reactions.
This one-second Neco Arc clip captures the Tsukihime mascot character stretching out a goofy, sing-song vocalisation that sounds like 'gudaniiuiuiu', delivered in a high, bubbly voice with a playful wobble at the end. It has no music or background noise, just that bright, cartoonish utterance, which makes it feel instantly silly and lighthearted. Heard on its own, it lands like a tiny burst of chaotic anime energy, the kind of sound that makes a viewer smile before they even know why. It works best as a quick reaction, turning an ordinary moment into something absurd, cute and unmistakably Neco Arc.
