Philia is a young woman who is affiliated with Esther's tribe. She has a strong sense of will as she wants to protect her friends and family while letting everyone live their lives in peace. Like Esther, she also has an animal companion; a jellyfish named "Slim" who serves as a floating umbrella for her. In battle, Slim handles all of the work, attacking with its tendrils and launching poisonous shots on enemies from above.
