Ruby

General
Ruby is the protagonist of Wendigo Hunt. She lives with her father and often hangs out with her best friend Jax. She lives near the woods and sees Wendigos from time to time. She goes to see her therapist, Dr. Hauser, from time to time. Whenever Ruby sees and locks eyes with a Wendigo, she immediately feels immense pain in her stomach.

Family Situation
In chapter i, Ruby mentioned her father while listing negative things that happened since "last summer," so we can infer from that slide that her relationship with her father isn't a good one, or that her father is a negative presence in her life.

In chapter ii, we get a closer look into Ruby's family situation, when she mentions that her mother died, and when she refers to her father as an "asshole."
