Yuudachi wears a black sailor uniform shared with the first four ship girls of her class. She has straight long blonde hair with a hair ribbon on top and green eyes.

She exhibits carefree behavior, fortified by her frequent use of "っぽい" (ppoi) which can come off as very casual.

She is modeled after the 4th destroyer of the Shiratsuyu class of the IJN.
