Yuko and her family are asked to cater for a wedding between two customers, Sachiyo and Daisuke, with Megumi and her friends offering to help out with preparations and Hime suggesting they use the theme of 'four somethings' for the bride's outfit. However, Sachiyo informs the group that her best friend who was supposed to give her 'something borrowed', Iona's older sister Maria, has gone missing, so the girls ask Iona to deliver it in her place. On the day of the wedding, after Iona gives Sachiyo Maria's handkerchief, Hosshiiwa crashes the wedding and creates a Bride Saiark from the newlywed couple. Determined to protect the wedding, Cure Fortune appears and leads the Cures to victory, allowing the celebrations to continue.
Note: Cure Peach celebrates the 10th anniversary.
