Merrissa is weak compared to her oldest siblings and older brother, Kierian. She's only 4 years old and unaware she could die at the age of 14. Merrissa loves her mother extremely and loved her lullabies she sings. She's unaware she has a step -father as she's often in her room playing with Althea or Kenji, she is unaware of others being in her house as therefore she doesn't leave due to Healthcare's commands to Kenji and Althea to not let her leave and wonder around. She's extremely kind.
