"Poppin' Party 10th Single 二重の虹 Tandem Reunion 最高さあ行こう" is a Japanese phrase that translates to "Let's go, to the highest point, Tandem Reunion of the Double Rainbow." It appears to be a reference to the 10th single by the Japanese band Poppin' Party, which is a fictional band from the multimedia franchise "BanG Dream!" The phrase might be part of the title or lyrics of a song by Poppin' Party, or it could be a promotional tagline for the single.
