In September 2019, the band held its first-ever independently organized outdoor event in their hometown of Kansai. After a three-year hiatus, the event—PARASITE DEJAVU—was held again in October 2022 at Saitama Super Arena. The live performances from both 2019 and 2022 have been compiled. The 2019 event, PARASITE DEJAVU ~2DAYS OPEN AIR SHOW~, took place at Izumiotsu Phoenix in Osaka, chosen as the stage in their home region. It drew around 40,000 people over two days. DAY 1 was a solo headliner show, while DAY 2 was held in an omnibus format featuring various artists. This release includes not only the DAY 1 solo performance but also previously unreleased footage from DAY 2, along with a behind-the-scenes documentary!
