...I'm extremely aggitated that it's took me this long to find a suitable solution to my predicament.
Well, to put it simply, I wanted Kumi's exact ringtone really bad, and I've even gone so far as to go through each entire sound file on the disc. I found 3 snippets of her ringtone, but alone, they do not sound like her ringtone at all. I am almost 100% positive the game puts the 3 audio files together itself in some codified way so no one could rip the song off of the disc.
I've found a couple videos on youtube claiming to be the ringtone, but none of them sound like Kumi's exact ringtone...
I'm honestly getting desperate.
