I rarely have time to make my original arrangements so here's a karaoke cover in the mean time. Yes, I used the nKz version and for some reason it's easier to sing this since it has this live pop song feeling.

Although this song functions as a leitmotif to Ragyo specifically, what I interpret is more of a dialogue between Ragyo and Satsuki. It's like what both of them think mashed into one song. Both consider the world cruel and both want to be stronger. "Removing the withered flower" can be interpret as Ragyo's power hungry nature (to the point she abused and disposed her family) but could also mean Satsuki's rebellion against her. But I consider "What do you want from me" is specifically about Satsuki's thoughts thus continuing to the "I must pursue the enemy and become stronger" part.

Totally personal opinion tho, also explaining why Satsuki is the highlight to the bumper illustration (which you can view here: http://miudraws.tumblr.com/post/100256858613/evil-mom-doing-evil-things).

Pardon the lame Christina vocal run imitations. AND THE GERMAN, HAHAHA. As you probably know, I love to challenge myself singing in different languages. I "learnt" German from watching too much Die Mannschaft/FCBayern interviews. Do give constructive feedback though, it's always helpful.
