track 8 is called RAGNAROK, not Laguna rock and track 9 is Akai kakera.

No, Akai kakera is wrong because hahen is the correct romanisation for 破片 (fragments) and RAGNAROCK is correct because the track's title is ラグナロクwhich is ragunaroku and is a pun...

Thank you very much for the correction! There is always some confusion about how to read 破片 - all too often, it actually is read カケラ which doesn't really help... :P

That's almost wrong. I know this song, we can easily hear yukari say "Akai Kakera" in it.
