A character in Tsukihime and Melty Blood. The 10th and one of the oldest of the Twenty-seven Dead Apostle Ancestors and one of the most exceptional.
He is an accumulated chaotic mass of 666 beasts (his name “Nrvnqsr” being 666 in Roman Numerals, pronounced as Nero in Gematria) that swirl within him, and he unleashes these beasts to devour his victims blood, meat and bones whole. He plans to swallow Arcueid Brunestud in order to claim unrivaled power among the highest rank of vampires and is an old friend of Michael Roa Valdamjong.
In the Melty Blood series he is a reoccurring manifestation of TATARI.
