Tomoyo is the princess of Nihon country and the one who banished Kurogane from his world. Though she appears as a princess in the beginning, she is a recurring character in the series as “other” Tomoyos.

Though there are various versions of her, they all share the same kind, open, and somewhat mischievous personality. 

Another consistent trait they have is their immediate connection and slight obsession with Sakura.
