She was in a coma because of an accident a year ago, which is due to Kageyama. Before her accident, she gave Gouenji a gift (an amulet) to remember her.
During the FFI Arc, she is seen to be a smart and friendly child. She cares for her brother and is a big fan of him, wanting him to always win matches by showing at least one of his best shots.
In GO, her attitude has had a drasticly change from a sweet and cute little girl to a more serious and more focused person. Her kind attitude towards other people remains, especially towards her older brother who has now become Fifth Sector's Holy Emperor (until near the end of the season).
She has black eyes and brown, braided hair, a partially pointed spike on the right side of her head and her bangs are parted into three strands. In GO, she still ties her hair into two braids at each side of her head but there are no spikes, and the colour has changed from brown to pink. She wears school uniform-like clothes: a white shirt with gray jacket and pinkish purple tie. This is partnered with a blue pleated skirt, dark blue socks and brown shoes. Yuuka is usually seen holding a bag.
While being in a coma, her brother thought she woke up. However she finally woke up after Raimon Eleven won the Football Frontier.
After Raimon won the Football Frontier, she woke up when Gouenji visited her in the hospital room. After some time, Aliea Gakuen took her hostage and threatened to hurt Yuuka if Gouenji scored in their next match. Their threats weren't mentioned and clear to the audience, but it was easy to see that Gouenji took them seriously and missed the goal twice because of said threats. This shows how much Gouenji loves his little sister and would do anything for her.
She was seen to have made lots of friends in her school. She was also seen to be waiting for Shuuya to tell him something about what she does during school, and was very excited to show him the 100% she got on her mathematics test. She seems to be very bright. In episode 85, she was seen at the airport, while Inazuma Japan are going to go to Liocott Island. In episode 123, she was surprised as Endou's God Catch was suppressed by Hill's Double Jaw during the finals between Inazuma Japan and Little Gigant. Her last appearance was in episode 126 where she is seen with her father watching her brother graduate from Raimon.
