Hien y Souhi
Sōhi (蒼氷 Sōhi) and Hien (緋炎 Hien) are the twin daughters of a family that has protected Hinoto for generations. Out of respect for the dreamgazer, they address her as "Princess" (姫様 Hime-sama). In the TV series, they are actually Hinoto's shikigami.

In Tsubasa, "Sōhi" and "Hien" are a pair of swords Syaoran and Kurogane obtain in Ōto Country.
