"Prismatic Oath" A classic sparkly song symbolizing QUARTZ. The theme is "Four people of different colors meet and become one light."
"Secret Gem" A mellow medium ballad. The concept is "Even if no one else notices, I alone know your brilliance."
"4U" The title plays on "For You" and the "4" members; it's a song dedicated to the fans. The theme is "The reason the four of us are here was to meet you."
"Kiss the Crown" A slightly mature and composed prince-style song. A song specialized for fan service with the line "Just for tonight, let me be your prince." Finger hearts and winks are included in the choreography, with highlights for each of the four to appeal to the camera. A song that maximizes the good looks of QUARTZ.
"LOCK★ON!" A catchy up-tempo song. Specialized for fan service.
"MIDNIGHT VELVET" A song with a mature and sexy atmosphere.
