The Spread Shot of Merlin Prismriver, the electronic musician (a Touhou LW original). She fires electronic sounds at her enemies. When a very short delay separates two sounds, the preceding sound absorbs the latter. It's kind of like the doppelganger effect but for sound. This phenomenon can apparently be used to create ambient soundscapes with monophonic tracks. There's always more to learn about spirits and souls.

The Focus Shot of Merlin Prismriver, the electronic musician (a Touhou LW original). She fires spirit energy noise. Apparently, audio recording devices can sometimes record the voices of the dead. However, this isn't necessarily something to fear, as it could be a message from a guardian spirit.

A Spell Card of Merlin Prismriver, the electronic musician (a Touhou LW original). She recreates a musical performance that took place near the Sanzu River. The Ruined Western Mansion near the Misty Lake is the Prismriver family home. Some records indicate that the three Prismriver sisters were accompanied by a person called Layla when their residence first appeared in Gensokyo. It's theorized that Layla conjured the three Prismriver poltergeist sisters into being with her magic and that she lived together with these poltergeist sisters until she passed away. This was before the poltergeists started performing, so perhaps their feelings of regret at not being able to perform with Layla created false memories in their minds.

A Spell Card of Merlin Prismriver, the electronic musician (a Touhou LW original). She plays a song that utilizes a group of soloists accompanied by an orchestra. It's theorized that the three poltergeist Prismriver sisters are based on Layla's older sisters. The young Layla missed her sisters so much that she conjured the poltergeists. Anyone familiar with magic should be able to recognize the difficulty of performing such a complex spell. In fact, the magic was so powerful that the poltergeists managed to persist somehow after Layla passed from this world. There are rumors that the former head of the Prismriver family, Count Prismriver, possessed a magic item before he left his family in ruin... Layla might have used that to cast her spell.

The Last Word of Merlin 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 known throughout Gensokyo. They were incredibly popular, so chances are the Prismriver Ensemble have heard of them. However, due to a lack of reliable sources, the sisters' opinions on Yougakudan's futuristic music are a mystery. Regardless, this world's Merlin remembers this music of the future... or rather, she has started to remember. Yougakudan wanted to send a message that could only be conveyed through music, and now, after all this time, it is being heard.
