- "I had a dream last night, the moment we could be together was just short, we were not far away from each other."— Umji
The story of the six girls is covered in all of their music videos note , following them since the high school days in "Glass Bead", "Me Gustas Tu" (original and Japanese version) and "Running Through Time (Rough)", a trilogy completing a school cycle as freshmen year, school club festival, vacation and graduation year.
After the sorrowful graduation day, the story became non-linear, complicated and mysterious things started to happen. The girls meet in a retro and Ambiguous Time Period timeline in "Navillera", which may or may not have ties to the high school timeline. They have a Trophy Room, which could be remnant of school days, and a romance between two of the girls starts.
"Fingertip: The Awakening" is a space opera-esque story where the girls project themselves into an astral plane, dubbed as a "consciousness, awakening and lucid dream" journey. The story also introduces a door (whether it is a portal through time or space) and "glass" beads, that could be mementos.
Tying the universe together, "Love Whisper: Parallel" and "Summer Rain: Rainbow" continues the story in parallel worlds or an Alternate Timeline. The music videos connect with the past and the future.
- "All days are nights to see till I see thee and nights bright days when dreams do show thee me."— Sonnet 43, Shakespeare
The Solar and Lunar trilogy begins with "Time for the Moon Night" and "Sunrise: Time for Us" is the continuation, even if "Sunny Summer" is almost like a spin-off, it gives hints about the story with Shakespeare's Sonnet 18 and Sonnet 48 talking about day, night and dreams. "Memoria" and "Fallin' Light" can be directly related as well, but the focus is a "knocking on heaven's door" theme instead of a lunar Ritual Magic, even if both series are intertwined.
