She is voiced by Maaya Sakamoto in the Japanese version of the anime, and by Amber Cotton (TV series) and Trina Nishimura (OVA) in the English version of the anime.
She is a princess of a feudal country called Japan who sends the ninja Kurogane on the quest that causes him to join the dimension travelers. Tomoyo is the Tsukuyomi, a powerful miko sorceress responsible for maintaining the wards of Japan that protect the country from demons.
She gives up her dreamseer power to Yūko as the price for bringing Kurogane's group to Japan as she manages to see them in danger following their encounter with Ashura-ō.
