Dianna Soreil

Dianna Soreil is the major heroine of Turn A Gundam anime series.

History
The Queen of the Moon, Dianna Soreil is the hereditary ruler of the Moonrace. Now that the Earth has regenerated from the destruction wrought by the Dark History, she believes that it is time for her subjects to return to Earth. Dianna lands a colonial force on the Earth in the hopes that they will be allowed to live in America's sparsely-populated sunbelt area. Unfortunately, she fails to take Terran resistance to the migration into account, and does not anticipate that her more ambitious subjects might turn against her in her absence. Events quickly spiral out of her control.

Dianna has lived for centuries using the Moonrace's cryogenic techniques. Her desire to live on Earth is a product of her weariness with her unchanging life on the Moon. She is an intelligent and commanding leader, but she lacks the drive of her young double, Kihel Heim. Dianna is overjoyed when assuming Kihel's identity allows her to lead a simple life withRolan. She only returns to the Moon in order to correct the mistakes she made in her rash rush towards repatriation.

At the end of the series Dianna permanently switches places with Kihel, and it is revealed that Rolan took on a mission to leave Sochie behind (,hence the kiss)   out of loyalty to Dianna and  accompany her to a small peaceful cabin on earth, where he will   dutifully  watch over her until her inevitable death due to illness caused by long periods of hibernation (,which is hinted at by her walking stick). The ring  Dianna  is shown wearing was not a  ring of  marriage to Rolan but a momento of Will Game. The ambiguity of the ending sequences containing Rolan, Sochie and Dianna has caused much confusion and debate between fans as to its intended meaning by the creators.
