Yolei is a short-tempered girl, but is also sentimental. Like Mimi, she's quick to cry and doesn't want to fight. She lives in the same block of apartments as T.K. and Cody, and has known the younger boy for some time. She has an older sister. Her interests include computers. Her family runs a convenience store, which she works at sometimes. This is why she's the one who usually keeps the Digimon fed while they're in the real world, though her family doesn't really approve of all the food she's taking.
Although she loves her family she often wishes she was an only child.
