Manga Like Nanahime Monogatari

In a corner of a continent, a kingdom was divided into seven major cities, each led by a princess who was supposedly the illegitimate children of the previous king. One of them, a nine-year old orphan, was chosen as the princess of Nanamiya Kasen. She was supported by the warrior General Ten Huo and his military strategist Toel Tau. She realizes that both of them are liars in varying magnitudes and their true intentions are unknown, but she went along with their plans as they cheerfully told her that the three of them will take over the entire kingdom. However, when she turned twelve, the neighboring city of Tsudumi began its invasion of Kasen....... This is a story about a girl who is tossed about by the currents of fate, but who faces her own destiny with sincerity.
