"As long as you are loyal to the royal family, we will stand by your side. As long as it does not stand in the way of protecting you, we will abide by your decisions."
The leader of the Sailor Quartet, Ceres is a dedicated and cool-headed leader, ready to run into battle and to what is necessary to protect her princess, Lady Serenity. Free from Nehellenia's evil grasp, Ceres wants to show her princess and her queen how grateful she is for their second chance--and she wants to make sure that her sisters do, too.
While Lady Serenity strains to express her independence, Ceres seems almost all-consumingly bent on expressing her loyalty, both to the princess and the palace. Although she's known for her interest in fashion and horticulture, Haruko pushes aside her personal wants and interests for the sake of her princess, even if Lady Serenity neither needs nor wants Haruko's obedience.
Eventually, Ceres' younger sisters begin to strain against the leash that Haruko has put on them when they see Lady Serenity break free of her parent's constraints. Used to the obedience and loyalty of the rest of the Sailor Quartet, Haruko protests when they begin gaining interests--and unique powers--of their own. But Haruko may have to realize that there's more to life than being a Sailor Guardian--that being a rounded person means seeking a path for yourself...
