^ Yes, it's so sad that there is not a lot going on in this thread, because I personally LOVE Kalafina.
I have only discovered them a few months ago, but since then I'm addicted to their music.
Mhm...my favourite song? This is very difficult, because I LOVE most of them SO much, but I have to say
Lacrimosa. I fell in love with this song from the first moment on and I can't get it out of my head anymore.
Kalafina's music really makes me feel like I'm walking in a fairytale.
Some other favourite songs of mine are: "fairytale", "serenato", "storia", "ARIA", "Magia", "progressive" and "Hikari no Senritsu" (among others!)!

My favourite B-side is definitely "lirica"!
I'm also addicted to their PVs. Whenever I watch them stories start forming in the back of my mind and I just feel like sitting down and writing them all down!
And don't you dare asking me what my favourite MV is, because I LOVE them all and can't choose between them!!
Wahhhh~~
I'm so looking forward to their new album!
