Nether Sign "Endless Evening Cherry Blossoms" 
Yuyuko stays near the center of the screen, shooting groups of 4 blue butterflies in all directions except directly below herself. When the butterflies reach a wall or the ceiling, they will burst into a few cherry petal bullets that vaguely aim at the player. The firing rate of the butterflies slightly speeds up as time passes. This spell will not give life or bomb spirits on Easy or Normal.
