Stage 4 of Touhou Embodiment of Scarlet Devil, where difficulty suddenly rises. A long stage with near indestructible books attacking everywhere. Streaming is important in this stage, as well as memorizing the enemies' spawn positions.

Patchy uses different spellcards for different shot types, with Reimu B's being the hardest. Marisa A's are barely manageable.
