The official website for Japanese rock band Sonar Pocket has announced that its three members: matty, eyeron and ko-dai will appear as themselves in an upcoming episode of the Nijiiro Days TV anime. It is one of the seven challenges, which have been held as their debut seventh anniversary project. Other challenges include running the Fukuoka Marathon last November and holding their first request-only concert in May 2016.
