SZZU has the appearance of a young, blonde lady wearing glasses and a spiked ornament in her forehead that looks like a coronet. She wears futuristic, orange-coloured armor resembling a dress with large shoulder pauldrons and black gloves. She is quite knowledgeable of human emotions and behaviour, and is the only one who truly understands her fellow Apostle CKRY, in spite of the latter's violent and savage demeanour. She does not display any particular ability in contrast to her fellow Apostles (like MZMA's control over fire, for example), and presumably centers on close combat. She wields a large, yellow blade with a uniquely shaped hilt.
