Interstellar Commander Crown Prince, stop staring at me!

Tiara, an orphan from the 21st century, was reborn as the only daughter, after thousands of years, of the House of Flecker from the interstellar era. Due to genetic defects, her mental power cannot keep up with her physical level making her unable to talk nor do normal things that an interstellar child can do. Even though she was treated like a princess by her parents and several elder brothers, she was unable to escape the tragedy of genetic breakdown forcing her family to keep her in a dormant capsule and send her to the planet of the best physician in the Paxley Galaxy, unfortunately, an incident happened that threw her to an inhabited planet. Tiara: Ugh! I haven't enjoyed being a little princess yet! A certain commander: Don't worry baby, I'm coming for you (~*3*)~ Several brothers: Did we agree? \(`-`)/
