Personality & CharacterEdit
Gruier is generally friendly and sociable, and doesn't let her position get in her way at all. She is a little naieve in some matters. She tries to be helpful and doesn't particularly like being left out. At first, she hid a number of important details from others herself (not without guilt), though this isn't the case later on. She is willing to encourage underhanded methods when the need arises .
Skills & AbilitiesEdit
As a member of the yacht club, Gruier has knowledge of how to fly a dinghy from training simulations (though she hasn't flown one for real ) and experience at operating certain systems aboard the Odette II. She also has some knowledge of how to operate some systems aboard the Bentenmaru. Gruier is fairly good at stowing away and does so quite a few times . She can't swim .
Due to her status, she received elite education since childhood, and focuses mainly in diplomatics, which the Monarchy of Serenity is known for. She is also really good at telling if a person is telling the truth or not due to the education she received, unless the person telling a lie goes to the extent of believing the lie as truth . She is also a capable painter .
Marika and Gruier's friendship began when Gruier sought the Bentenmaru's help in finding the Golden Ghost Ship. Gruier soon came to respect and admire the young captain's skills and judgement, and was also happy to have someone she could casually associate with as a friend. She was troubled at keeping certain details of the mission from Marika and the crew, and not being able to help more in the search .
Though Marika went behind her back to ensure a peaceful resolution to the events on Golden Ghost Ship, she was grateful to her for doing so. Afterwards, Gruier does what she can to help Marika, be it providing information , finding a disguise  or even helping fly the Bentenmaru , often disregarding her position.
At the start of the series, Gruier's relationship with her sister was rocky due to their disagreement over the issue of the royal family's future . However after the situation was resolved, the two reconciled .
Gruier and Chiaki share a budding friendship that sprouted from their respective relationships with Marika. Though they have yet to become close friends, they are similar in that they can engage in a relatively more mature conversation compared to their silly moments with Marika.
- When she is not in formal attire, Gruier's features are similar to that of Princess Serenity/Usagi Tsukino from Sailor Moon. The only real difference is that the tails of Gruier's hair are braided and are split into two additional tails.
- Due to Gruier's tendency to stow away, Marika calls her the stowaway princess (密航王女, Mikkō Ōjo) quite early in the novels whenever she does so. This nickname is also the name of her theme in the anime .
- When she first appeared as a stowaway on the Bentenmaru, Gruier was 140 cm tall and weighed 34kg .
