The band's tenth studio album, "Cross", was released on December 18, 2019. Co-produced by Steve Lillywhite, it marks the first time the band has worked with a record producer. It was their first album to top "Billboard Japan" Hot Albums chart. On December 21 and 22 the band performed two 30th anniversary Christmas concerts at Saitama Super Arena. From February 1 to May 31, 2020, Luna Sea was scheduled to have a nationwide 30th anniversary hall tour titled Cross the Universe with over 29 performances in 13 cities. However, all tour performances from the end of February on were postponed until 2021 due to the COVID-19 pandemic in Japan. On April 28, 2020, the band released the digital song "Make a Vow", which was produced remotely within two weeks as an answer to the pandemic. A day later, their twenty-first single "The Beyond Gunpla 40th Edition" was released in limited production. It became their first song in over 20 years to top the Oricon Singles Chart.
