VIVIDIVA (비비디바) is a five-member Korean pop girl group under DN Entertainment. Their concept is "performance idols", which means that they perform live on small stages to establish a more direct and personal link with the public.
On January 25, 2015, DN Entertainment posted on its YouTube channel the first episode of a show called "VIVIDIVA TV" to introduce the group and its seven initial members, but it was interrupted after three episodes. The company explained that the group needed further training and the debut was postponed.
VIVIDIVA officially debuted - in South Korea and Thailand - on September 15, 2015 without two members, N.na and Kana, which had been absent from activities since Summer. Their promotional photos were deleted from the official websites, Twitter's account username changed from vividiva_7 to vividiva_5, and the individual teasers of the two girls were removed from Youtube. VIVIDIVA held promotions both in South Korea and Thailand through TV and radio shows.
On March 24, 2016, DN Entertainment announced the disbandement of the group and that the label would now operate under Elephant Entertainment. Sunyul joined Elephant Entertainment new girl group Twinkle, scheduled to debut in 2016, but this never happened; instead, she debuted in girl group Sha Sha in 2018.
