Louanna Astrea

Louanna Astrea (ルアンナ・アストレア) is Heinkel Astrea's wife and Reinhard van Astrea's mother.

History
When Reinhard was two years old, Louanna was afflicted with a condition known as Sleeping Beauty (眠り姫 Nemurihime) and is still sleeping to this day without any changes to her body. Some time later, Ferris examined her but determined that she didn't need to be treated.
