Scarlet Mist Solo No. 3, ''Brass Performance''

A Spell Card of Merlin Prismriver from the world shrouded in scarlet mist (a Touhou LW original). This attack will later become ''Nether Trumpet: Ghost Clifford.'' While poltergeists are more stable than phantoms, they are still spirits, so presumably, they are also easily influenced by temperament. Yuyuko and Eiki (and Yukari) probably chose to send the poltergeists to investigate because they would act like canaries in a coal mine. They planned to infer the current state of the incident by seeing whether the Prismriver Sisters were affected by anything on their journey. The sisters also decided to use their own Spell Cards as a kind of litmus paper. The Spell Cards crafted by these talented musicians and composers were stained scarlet.
