The Spread Shot of Lyrica Prismriver, the electronic musician (a Touhou LW original). She fires electronic sounds at her enemies. If someone told you your sense of sight influences your hearing, would you believe them? It seems our senses are far more complex and mysterious than we could've ever imagined. Perhaps we mishear things because of the souls whispering in our heads. If it's true that sight influences hearing, that opens the doorway for infinite forms of musical expression.

The Focus Shot of Lyrica Prismriver, the electronic musician (a Touhou LW original). She fires spirit energy noise at her enemies. Apparently, there have been attempts made by those in the spirit world to communicate with the world of the living. The souls of the dead are conscious beings, so it makes sense that they would work together to try and accomplish this. If that's the case, then perhaps communicating with them won't be half as difficult as expected. Attempts to do so are essentially CETI (Communications with Extra-Terrestrial Intelligence) but for dead souls.

A Spell Card of Lyrica Prismriver, the electronic musician (a Touhou LW original). She combines solo and group performances in this attack. Details about the future world's four Prismriver sisters are unknown. No reliable documentation that even hints at possible truths has been found. However, in this world, it seems they all fondly remember playing as a part of a quartet in front of the fire in the mansion's living room. These memories are false and far too idealistic, but to spiritual beings, they are as good as real.

A Spell Card of Lyrica Prismriver, the electronic musician (a Touhou LW original). She plays a concert filled with illusionary noise. It's possible the Prismriver Ensemble was invited to perform at Hakugyokurou even before traveling between Gensokyo and the Netherworld became easy. Whether the Yama granted them special permission to do so or if it was authorized by those at Hakugyokurou is unclear. The three sisters haven't explicitly said why they perform in the Netherworld, but it's presumably because there's a chance they'll find Layla among the spirits waiting for reincarnation there.

The Last Word of Lyrica Prismriver, the electronic musician (a Touhou LW original). She performs an audience-less live show and streams it on the All Spirit Network. There was once a band called Yougakudan, who are said to have changed their name to Gengakudan, only to disappear. Even now, would their music be considered the sound of the future? Or has enough time passed for it to have become the sound of the past? The events of history are arranged in chronological order, but they aren't restrained by the shackles of time, for they all exist in their own "now."
