That's the one song I haven't been able to find kanji lyrics for yet. But I'll keep scoping and see if I come across the. I've tried most of the uta related sites but I'm pretty sure I came up empty each time. I can't find kanji, I get most of my kanji lyrics from Japanese lyrics sites, which sometimes do not have peoper lyrics for tracks that have been released for months or even years (often b-sides especially get the short end of the stick on uta-net and other sites), all I could find was a romanized version here but with no accompanying kanji lyrics.
If you want to try searching for yourself, there's an applet that allows you to bypass Japanese lyric sites and their no copy feature called lyric get, and under the "examples" tab, there are numerous Japanese lyric sites. In order to get past the copy protection restrictions you just go back into the applet under the lyric get tab and paste the link to the song's lyric page. I haven't been able to find Dareka's kanji lyrics on most of those sites thus far but if you want to take a gander at it…
