The Prismriver Sisters (プリズムリバー三姉妹 Purizumuribaa San-shimai) are three characters named Lunasa Prismriver, Merlin Prismriver and Lyrica Prismriver, together appearing as the stage 4 boss of Perfect Cherry Blossom. Lunasa, Merlin, and Lyrica are collectively called the "Prismriver Ensemble" and perform at parties and festivals. At first sight, their instruments (Lunasa with the violin, Merlin with the trumpet, and Lyrica with the keyboard) may seem scattered and disconnected, but they still perform magnificent music. There is also a fourth Prismriver sister, named Layla Prismriver.

These three sisters are poltergeists, made by Layla Prismriver to have the appearances and personalities of her three older sisters from whom she had been separated. Thus, they are technically all the same age since they were presumably created at the same time. They only act out the roles of oldest, middle, and youngest sister based on whichever one they were made to resemble.
It is known, based on their official profiles and from comments by Eiki, that none of the original four sisters are still alive today. However, it's unknown how long ago the events that spawned these three poltergeists occurred.
- Performing on musical instruments without hands or feet
In Perfect Cherry Blossom, this is the main ability that all three sisters have been specified to have. This probably derives from the ability poltergeists have, put to specific use in performing with musical instruments. By manipulating the spirits of instruments, they're able to manipulate the spirits of notes to create sounds. Since they needn't have direct contact with the instruments, they're able to play music impossible to play by hand.
Since the three sisters' musical performance is something that they have learned themselves after Layla's death, their previous abilities were probably along the lines of "moving things without hands or feet" or "making sounds without hands or feet". The former is because poltergeists in general can move things and make them float. The latter is because in the general phenomena of poltergeists, they can be heard from anywhere (a rapping noise, for example).
Sometimes "Prismriver" is translated as niji-kawa (虹川), which means "rainbow river", even though "rainbow" does not mean "prism". Thus, Layla and her sisters are sometimes referred to as the "niji-kawa sisters" (虹川三姉妹).
As of Alternative Facts in Eastern Utopia, Raiko Horikawa has joined the Prismriver band.

- Their spell card background has an image of a score for Last Spring, from Two Elegiac Melodies by Edvard Grieg.

- The Prismriver Sisters, along with Mystia Lorelei and Yuuka Kazami, are the only Windows-era-spell card-capable characters not to appear in Shoot the Bullet.
- Since Lunasa is the eldest sister, she's commonly referred to as "older sister" (ルナ姉 luna-nee).
