Saki is a teenage girl with blonde shoulder length hair, with her bangs covering one of her eyes. She wears a sailor-style jujutsu uniform. Saki also wears a black choker along with a necklace that has a golden trinket styled after the Jujutsu High crest. Saki is a strong willed, stubborn, and rambunctious person. She can be loud sometimes, much to the annoyance of Nobara, and has a bad habit of running headlong into her missions without a plan. Despite this, she gets along well with her class.
