Yuuna and the Haunted Hot Springs Vol. 20 (manga)

Not everyone at Yuragi-sou gets to participate in Sports Day with Kogarashi. Asaka and Matora come up with a solution: a special irregular barrier that will only open when the Sports Day is completed! Not only that, but the winner gets to use the Tenko summer home in Hawaii!! The girls can go all-out with their powers and they do—until they realize that all the equipment, including their clothes, is being inhabited by Kogarashi! Now none of them can focus! Who will win this unorthodox Sports Day?
