Nazuna Costume Mission is a Sub Story Mission Type categorized under a banner labelled "Wear the Outfit From That Time (あの頃の衣装を身に着けて)". They came about from a poll held on 7/27/2018 (7-2-7 as Na-zu-na) that had players vote for their favorite Nazuna outfits. The top three outfits each got featured in their own short stories in the form of very easy missions. These missions were added a month later on 8/27/2018.
