A live musical was written based on the manga and anime series, coming out to critical acclaim in both Japan and Korea in May 2015. Interestingly, the musical was originally written in English then translated into Japanese, but as of April 2016, no English scripts or sheet music has surfaced. An English demo album was recorded in New York City (featuring Broadway stars Jeremy Jordan as Light and Jarrod Spector as L), but the show has yet to be officially picked up by Broadway.
