One of the colonists in Tets story and the supposed older sister of Riku. She was also the founder of Elchea after the Great War and is Stephanie Dolas direct ancestor. Couronna has a very similar appearance to Stephanie Dola however her hair is slightly longer and darker. She cares about Riku going as far as calling herself his sister after he had lost his family. Though she is a mere Imanity she seems to be sensitive to things as she was able to figure out that Shuvi was not an Imanity right away.
