Because she is an evil-ass ghost who will bite your heart, and fuck you up in your dreams.
It's a pretty dead on comparison, I think.
Edit: Speaking of evil-ass ghosts, I finally got to Utsuho! Fuck yeah!
Managed to get past Boss Orin with 2.6 lives, even. I got no idea how I did it. but I did it and that's the important part. The crows suck, but on easy mode (at least) they don't only seem to attack vertically when you're low to the screen, so I don't have to worry about being sniped from the side, made keeping properly chill easy. I hate those flames and their seekers, though. Lost a life to them.
Managed to cap final Orin. Easy Blazing Wheel wasn't that back, just keeping a good left-right motion going. Goddamn if it wouldn't be easy to lose the rhythm, though.
I even got Utsuho down to two lives. I capped her first three attacks; netting me a precious life. Her first and third isn't bad. Her second, though, is full of dammit and I am surprised that I managed to cap it. The fourth ate of two of my lives. One because I just went the wrong way, the other because I ended up in a bad corner. Then her fifth attack caught me completely off guard and ended it all. But I did better than I did on my first fight against Easy Yuyuko or Normal Kaguya, so fuck yeah! It is a good day.
Also I finally remembered to hit save replay, because I never remember that in SA or MoF.
