Saiuri is a young woman with a strong, tall and very voluptuous build. She has very vibrant pink eyes with white irises framed by large thick eyelashes on the top. She has extremely long rose pink hair reaching past her hips with a single shoulder-length bang on the right side of her head and the left side braided back with tiny cherry blossom flower ornaments. Saiuri wears a purple-tinted version of the standard Demon Slayer uniform with rather long hakama pants, buttoned white leg-wraps.
