Prismriver-Schwestern

The Prismriver Sisters (プリズムリバー三姉妹, Purizumuribaa San-shimai) are three characters name Lunasa Prismriver, Merlin Prismriver and Lyrica Prismriver, each first 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. Although at first sight their instruments, Lunasa with the violin, Merlin with the trumpet, and Lyrica with the keyboard, seem scattered and disconnected, they still perform magnificent music. There is a fourth Prismriver, named Layla Prismriver.

General Information

Because these three sisters are created Poltergeists who were made by Layla Prismriver to have the appearance and personalities of her three older sisters from whom she had been separated, 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, although it's unknown how long ago the events were that spawned these three poltergeists occurred.

Ability

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 ability was probably along the lines of "moving things without hands or feet" or "performing notes without hands or feet". The former is because poltergeists in general can move things and made them float. The latter is because in the general phenomena of poltergeists, they can be heard from anywhere, like a rapping noise for example.

Background Information

Name

Sometimes "Prismriver" is translated as niji-kawa (虹川), which means "rainbow river", even though "rainbow" does not mean "prism". Thus, she and her sisters are sometimes referred to as the "niji-kawa sisters" (虹川三姉妹).

Noisiness times 3. They have the ability to perform with instruments without hands and feet—times 3. The Saigyouji family enlisted the Prismriver sisters to provide music at a convention, promising them a flower-viewing in return. The three of them are always summoned to banquets and such; their music stirs things up. They're like ghostly versions of publicity-generating cultural icons. This time, the Saigyouji family is holding an extravagant flower-viewing festival, so they would naturally be invited.

At that time, there was a human noble, Count Prismriver. The Count had four daughters, whom he cherished. However, due to an unfortunate accident, the four daughters were orphaned. Without any other relatives, each daughter went her own separate way. The fourth daughter, Layla, was unable to leave the mansion that held so many of her memories. Using her strongest power, she conjured poltergeists with the appearance of her older sisters, then vanished along with the mansion and the poltergeists. Time moved on, and the death of the four people from those old days came to pass; the poltergeists' mansion remained in Gensokyo. The three poltergeist sisters continue their noisy lives in that mansion to this day. The musical performances given by those three, at various places of announcement, a fusion of casual rhythm and classical instruments, are loved by the inhabitants of the cheerful Netherworld. Yet, the performance itself provides no additional effect, and does not heal.
