Грюер Серенити

The seventh princess of the royal family of Serenity, hailing from the Serenity constellation, has long light hair. She knew Marika Kato's father. She escaped her native system and asked "Bentenmaru" for help to reach the golden ghost ship that became the first colony of the Serenity people 1000 years ago. She sometimes assists Marika in her pirate activities. In reality, she intends to destroy the artificial womb on the ship where the embryos of the Serenity royal family are stored, justifying this by the fact that the royal family is responsible for the chaos and instability in their native world. Because of this, she is pursued by a fleet led by her younger sister Grünhilde. In the end, it is revealed that after 1000 years all the embryos have died, except for one child who was extracted. Later, Gruer decides to settle on Marika's native planet, attend the Hakuho Academy, and join the yacht club.
