Neco-Arc is a diminutive, cat-eared parody of Arcueid Brunestud, the protagonist of Type-Moon's visual novel Tsukihime. Originally appearing as a comedic relief character in the Melty Blood fighting game series, Neco-Arc became an internet sensation due to her chaotic personality and absurd vocalizations, most notably 'Burenyuu.' In recent years, she has been revitalized through ironic memes, often depicted drinking 'Pilk' (a mixture of Pepsi and milk) or engaging in nonsensical, high-energy antics. The character's popularity stems from her gremlin energy, making her the perfect vessel for shitposting and surreal humor across platforms like Twitter, TikTok, and YouTube.
