"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 puns 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 message "Make me your prince for tonight only." The choreography includes finger hearts and winks, with highlights for each of the four to appeal to the camera. A song that maximizes QUARTZ's good looks.
"LOCK★ON!" A high-tempo song with a great vibe. Specialized for fan service.
"MIDNIGHT VELVET" A song with a mature and sexy atmosphere.
Rei Solo Song "My Sweet Princess" Akane Solo Song "BURNING UP!" Aoi Solo Song "BLUE TEMPTATION" Sui Solo Song "Hidamari"
