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?
This title, along with fellow Weekly Shonen Jump title Bokutachi wa Benkyō ga Dekinai (We Never Learn) are both post-Nisekoi harem romance had a work around over the inevitable ending of choosing only one girl or the girl who won. That would be presenting the non-winning routes as alternate timelines. Bokuben presented them as side stories after the main ending. This title presented it as dream sequences or alternate futures.
I’d like to think it gave the supporters of the nonwinning girls the closure of seeing an alternate ending of seeing their respective ship sail.
