My top five favorite themes?
1)
U.N. Owen Was Her? - I think this brings out the savageness of Flandre while also bringing about an innocent side to her. I feel that it is perfect in every way.
2)
Beloved Tomboyish Girl - This song is like the song of my life, almost. I feel childish and stupid most times, and this song fits in right with that, and it even more amazing that Cirno can be childish and stupid, but can probe to be equally deadly. ^^
3)
Septette for the Dead Princess - This song is by far, the best final stage boss song for me. It conveys the feeling of savageness and refinement. The song to me is saying that she will kill you, but she will do it in a way that will not bring her down from her status... I hope that conveys what I'm trying to say...
4)
Diao ye zong (Withered Leaf) - This song is playful, befitting a cat familiar, and shows how bad luck can be seen where ever Chen goes, as she is the spirit of bad luck (I think).
5)
Lunar Dial ~ Luna Clock - I love how this song is purely driven by the need to kill whatever is targeted. She'll kill you with her knives, then will clean up the mess with a smile on her face. ^^
I hope I did that right. v_v
