In the said wedding ceremony, Kitagawa's Pretty Guardian Sailor Moon co-stars Ayaka Komatsu (Sailor Venus), Miyuu Sawai (Sailor Moon), Myuu Azama (Sailor Jupiter), and Rika Izumi (Sailor Mercury) went to the stage and say, "In the name of the moon, we will congratulate you!" They then performed the series' second ending theme song "Friend".
Seen below is one of the live performances of the said song, and on the right is the wedding photo of the couple.
As for her husband, DAIGO, he's delighted to hear the performance. "Since my wife is an actress, it's not every day I get to hear her sing, so it made me happy," he commented. The couple got engaged last October 2015, and registered their marriage last January 2016.
