Demitra "Mia" Kalogeras (middle, 19 years old) Appearance in the story: Tall, athletic build (she used to dance). Long (or pulled back into a bun) dark-brown curly hair, bright makeup even for class. Wears an oversized hoodie and designer sneakers. Always has her phone in hand. Role in the trio: Performer and "content face." Mia is responsible for social media. She films all the humiliating moments with Billie, edits them, but doesn't include them in the final videos; she just shows them to her sisters and laughs. She likes to "accidentally" include Billie in the shot and then comment at length on her awkwardness over dinner.

Sunday "Kailea" Kalogeras (senior, 21) Appearance in the story: Average height, with a regal bearing. Her long light brown curly hair is always styled (even in the dorm). She wears minimal makeup, but looks like she stepped out of a magazine cover. She wears a silk robe and expensive slippers in her room, emphasizing her status. Role in the trio: Leader and strategist. Sunday doesn't stoop to petty bullying—she organizes the system. She decides when Billie is "punishable" and when to ignore her. She speaks little, but her every word is an order for her younger sisters.

Eliana "Markella" Kalogeras (youngest, 17 years old) Appearance in the story: The smallest, she looks younger than her age. light brown curly hair, large eyes, often dressed in pastel colors and with bows. Her appearance makes her want to protect. This is Markella's weapon: "cutie." Role in the trio: Emotional manipulator and "stinger." Markella carries out all the verbal bullying, cloaked in innocence. She's capable of saying the most cruel nastiness in a sweet voice and then immediately adding, "Oh, what's wrong? I was being kind." If Billie complains, Markella will be the first to cry—and everyone will believe her.
