1stCast is... Well, they're not irreplaceable (duh, please note 2ndCast and 3rdCast), but they're IRREPLACEABLE. It's one of those "the original is always the best" things. 2ndCast was very different from 1stCast, and it's really a shame that people don't like them because they compared and saw only differences that SHOULD BE EXPECTED BECAUSE 1STCAST IS OLDER AND THUS MUCH MORE SEASONED AND KNOW MORE.

And when I watch Rokka, I can at least see more than Setomaru. There's the matter of Takki and all the IreiAi...

Oh, someone just YM-ed me and now I'm wondering if anyone other than Nikki has written TakkiSeto fics yet...
