Both the Pretty Cure teams from Kirakira PreCure a la Mode and Witchy PreCure! are attacked by Dr. Traum, whose new time-manipulating mech reverts them back to their younger selves. After the Hugtto PreCure force Traum to retreat, they learn that both Strawberry Hill and the Magic World have been frozen in time. Splitting into groups to find other Cures to help them, the girls manage to meet up with Love Momozono and Nozomi Yumehara before Traum arrives and uses time-powered Oshimaidas to stop time across the world.
