Jolyne, F.F, Ermes

Ermes:

Tough & determined Ermes doesn't scare easily. When she decides that she wants something, she can be incredibly persistent. She's willing to put herself in serious danger for what she believes is important, particularly when it comes to her sister.

Extremely loyal Her loyalty is one of her defining traits. Once Ermes considers someone a friend, she takes that relationship seriously. Her friendship with Jolyne develops into a genuine bond, and she repeatedly demonstrates that she can be trusted when things get dangerous.

Hot-headed Ermes can have quite a temper. She isn't the type to quietly tolerate someone insulting her, threatening her friends, or getting in her way. She can be impulsive and confrontational, especially when she's angry.

Clever & resourceful Ermes isn't just physically strong. She's good at figuring out how to use her Stand creatively. She's particularly good at exploiting the unusual properties of Kiss rather than simply relying on brute force.

Strong sense of justice A major part of Ermes' motivation comes from what happened to her sister, Gloria. Ermes carries a strong desire for revenge and justice, and this becomes one of the central motivations behind her actions throughout Stone Ocean.

F.F:

Extremely curious: F.F. initially knows very little about ordinary human life. She becomes fascinated by basic human experiences and constantly tries to understand things that humans take for granted.

Energetic and excitable: She's very enthusiastic and can go from completely calm to incredibly excited in seconds. Her reactions are often exaggerated and funny.

Blunt: F.F. doesn't have the same social understanding as the other characters. She tends to say exactly what she's thinking without worrying much about whether it's socially appropriate.

Loyal: Once she considers someone a friend, she becomes extremely devoted to them. Her relationship with Jolyne in particular develops into genuine friendship and trust.

Protective: F.F. becomes willing to put herself in danger to protect the people she cares about. Despite her strange origin, she develops a very strong sense of attachment to her friends.

Childlike in some ways: F.F. has an almost childlike fascination with the world. She can be surprisingly innocent about concepts that humans normally learn while growing up.

Emotionally sincere: One of her most appealing traits is that her emotions aren't fake or calculated. When she's happy, she's really happy; when she's angry, she's genuinely angry; and when she cares about someone, she genuinely cares.

Increasingly human: This is probably the most important aspect of her character. F.F. begins with little understanding of what it means to be an individual human being, but through her experiences with Jolyne and the others, she gradually develops her own identity, emotions, values, and understanding of friendship.
