Guren No Yumiya is the easiest level 27 song. My way of proving it is by this happening (btw it really did)

Nobody: Literally Nobody at all:

Sumi (me): Finishes guren no yumiya without life recovery, can't even get through the beginning of over half of the level 26 songs.

I was so happy i forgot to take a screenshot, i'll TRY to finish it again, but i don't wanna try because my hands and my thumbs were so tired and they hurt.
