Neco Arc is a chibi, cat-like parody of Arcueid Brunestud from Melty Blood and the wider Type-Moon universe. Small in size but massive in personality, she’s known for her chaotic energy, off-the-wall antics, and frequent fourth wall breaks that leave both characters and players completely bewildered. Unlike her more serious counterpart, Neco Arc thrives on absurdity—often acting in ways that make absolutely no sense, and somehow getting away with it.

She serves as a comic relief character, constantly interrupting the flow of scenes with her exaggerated expressions, weird noises, and bizarre dialogue. Whether she's spouting memes, mocking the plot, or just causing mayhem for the sake of it, Neco Arc brings a surreal, unpredictable twist to every situation she's in. Her presence in the Melty Blood games and other Type-Moon works is a reminder not to take things too seriously—and that even the most intense stories could use a little chaos and a lot of catgirl energy.
