DIV is a four-member rock band consisting of Vo. CHISA, Gt. Shogo, Ba. Chobi, and Dr. satoshi. Formed in 2012 mainly by Chobi and Shogo, the music video for the band's signature song, "Natsu no Yukue (Whereabouts of Summer)," has recorded 3 million views, and the total number of views for all music videos exceeds 10 million. To commemorate the first anniversary of their formation, their first one-man live, "ONE BY ONE," held on May 6, 2013, at Shibuya O-WEST (now TSUTAYA O-WEST), sold out immediately in 3 minutes. In the same year, their second one-man live, "ZERO ONE," held at Shinjuku BLAZE on November 3, sold out immediately in 60 seconds, earning them a reputation as 'the band with the most difficult tickets to obtain,' and they continued to lead the visual kei scene. They suddenly disbanded in 2016 without announcing a clear reason, but on August 13, 2023, after a seven-year hiatus, they announced their reunion live, "NEVER DIVIDED, JUST DIVE." The tickets, of course, sold out immediately, demonstrating their unwavering support. Further success after their reunion is highly anticipated.
