Inspired by "", Luna Sea designed and hosted "Music Aid Fest. ~For Post Pandemic~" on Fuji TV One on May 31 to support medical workers and others on the frontline of the COVID-19 pandemic. Essentially a television music festival featuring live remotely recorded performances to elicit monetary donations, over 25 artists participated, including Ellegarden, Char, Koda Kumi, and 9mm Parabellum Bullet. Luna Sea were set to perform at Saitama Super Arena on December 26 and 27, 2020 as their first concerts since the pandemic forced them to postpone their 30th anniversary tour earlier in the year. They were to be the band's first live streamed concerts with physical seats limited in capacity. However, both days were also postponed after Shinya tested positive for COVID-19 on the morning of December 26.
