Arashi and Guren-Kaina, twin siblings years younger than Sesshomaru, and just a little bit older than Inu-Yasha. One a traitor, the other, a loyal guardian. They are as different from one another as darkness is from light.
Hai, these two are OCs. Actually, they're going to appear in later chapters of my fic 'At War Against Fate'. (I'm working on a new chapter now, so it could be in the near future that I'll get to bring them in...)
Eventually I probably will make a manga of my own (but it will probably be in color, since I have no clue on how to use screen tone, much less where to find it! ^ ^;;; )
