Yumiko is the eldest of the Fuji siblings, with two younger brothers—Yuuta and Shuusuke. She's known for her surprisingly accurate tarot readings, which have become something of a ritual: the night before Shuusuke plays a match, she'll do a reading for him.
She first shows up offering Shuusuke a ride home from school, though her face remains hidden during these early appearances. Fans don't actually see what she looks like until the Kirihara vs. Fuji episode.
