Tamaki

Tamaki is Shiki's younger sister and the one who is prophesied to inherit the throne. She owns the Yata Mirror as proof of her royal lineage.

Having faith in an ancient prophecy discovered by her mother, she uses her royal artifact and the last of the divine spring's powers to summon otherworldly heroes into her realm. Tamaki believes that these heroes' powers will restore the spring's power sources across the land, which will in turn restore her now decaying world and usher in the new ruler's era.

Although her summoning spell fails and scatters the heroes, Tamaki is able to immediately find the Dynasty Warriors cast and explain the situation to them. They become her first allies since they realize that they can't return home until the spring is properly restored.
