Neco-Arc is a parody, cat-like mascot character from the Melty Blood series and the wider Type-Moon universe. She is a comical, miniature, and mischievous version of Arcueid Brunestud, often appearing in absurd gags, bonus content, and crossover material. Neco-Arc serves as a source of comic relief and meta-humor, contrasting sharply with the serious tone of the main cast. Her role in the series is primarily to entertain, satirize, and break tension through exaggerated antics and surreal dialogue.
