[Machine Translation] The feeling that makes you want to see them again. This single "Tetra Pop Theater" is a short story. Monochrome Mirai's 2nd single is completed after a year! This single is a condensed version of each POP STYLE created by the four members. The sound that you will discover something new every time you listen to it, the songs that will make you feel the story of each of them, and the life-size poems, all of which are worth listening to even though it is a single!
