She's a manager in the Nankatsu senior high school team (The strongest opponent! Netherlands youth, pages 6-7). She'll watch the last friendly match of Japan youth against Netherlands youth (The strongest opponent! Netherlands youth, page 75). She'll also watch the broadcast of Tsubasa's match against Santana's Flamengo (World youth arc, chapter 6, pages 46-47).
She'll be a member of All Japan's youth supporter's club, led by Sanae, and support Japan youth from the first round of the asian preliminaries (World youth arc, chapter 19, pages 26-27), and be surprised to see their sorry state (World youth arc, chapter 19, pages 29 to 31). Through someone she knows who's doing card reading, she knew that Japan youth would be cornered and facing a pinch, this being their match against Thailand, and also that 2 saviors would rescue them, correctly guessing that one of them was Wakabayashi, and assuming that the other was Tsubasa (World youth arc, chapter 24, pages 8-9), but will notice that despite their presence, Japan will still be cornered by Thailand (World youth arc, chapter 24, pages 24-25). Sanae will make her notice that the second savior was actually Aoi (World youth arc, chapter 25, pages 22 to 24), and she'll eventually agree (World youth arc, chapter 25, pages 60-61).
She'll go to Jakarta in indonesia with the rest of All Japan's youth supporter's club to support Japan youth during the Asia youth championship (World youth arc, chapter 29, pages 114-115), and congratulate Japan youth fortheir qualification to the World youth with a giant homemade flag which took a whole night to build (World youth arc, chapter 42, pages 13 to 15).
Returning to Japan, after a press conference, she'll go back to Nankatsu in Shizuoka. Yukari will do her best to leave Tsubasa and Sanae alone, dragging Ishizaki along who was slow on the uptake. Yukari will be surprised to be asked on a date by Ishizaki, and while it will be turned into a joke and quarrel between them, everyone else will wonder if something is going on between them and she will even admit that they are well matched (World youth arc, chapter 44, pages 2 to 13). Asking her grandmother, who is her card reader, to make predictions again, since her previous predictions were right, she'll be worried by her grandmother's attitude, who won't act like her usual self (World youth arc, chapter 46, pages 6 to 25). Her grandmother having a bad feeling for Japan, will eventually be making the prediction for Japan with a crystal ball (World youth arc, chapter 47, page 1), her grandmother will see a thick fog covering and blackening Japan, the gathering of the strong energies her grandmother talked about before is going to cause a disaster to fall on Japan, and her grandmother will more precisely talk about injuries and diseases striking the players and their relatives. This will make her remember about Wakabayashi's hands being injured again and Hyuga's mother, but her grandmother will affirm that the disasters aren't over, and the crystal ball will eventually crack (World youth arc, chapter 47, pages 6-7), making her grandmother unable to make any other prediction, just as one disaster is already striking Japan: Misaki will be severely injured, and while his life won't be in danger, he won't be able to participate in the World youth (World youth arc, chapter 47, pages 20 to 25). She'll cut her hair to exorcise Japan youth, joping that no other player will get injured, and will tell everyone to chase the bad spirits with positive supports (World youth arc, chapter 49, pages 1 to 3).
She'll watch the World youth from the stands with the rest of the supporter's club (World youth arc, chapter 51, page 8).
