Gender: Female Age: 9 Personality: Lethargic and cold. However, she possesses a certain charm, a femme fatale quality even as a young girl. Details: Her parents are divorced and she lives with her mother, who works as a hostess and neglects her. She is severely bullied at school, where Marina calls her a "parasite." However, she shows a smile appropriate for her age when she is with her beloved dog, Chappy. First person: I (polite/reserved)

Gender: Unknown Personality: Energetic, pure, and positive. Does not understand concepts like death or insults like "parasite." Details: A mysterious alien traveling to spread happiness. Shizuka saved him when he was on the verge of starvation, and he has become very attached to her. He struggles to make Shizuka happy using his "Happy Tools." He ends his sentences with "-ppi." First person: I (soft/childlike)

Gender: Female Age: 9 Personality: She has a cute face but a difficult personality; she spits venom with a smile and is the ringleader bullying Shizuka. She calls Shizuka names like "parasite" and "daughter of a slut." She personally assaults Shizuka, destroys her belongings, and scribbles on her desk (while the teacher turns a blind eye). Her followers join in the bullying. Details: Her home life is broken. Her father rarely comes home, spending his time with a hostess (Shizuka's mother), and is verbally and physically abusive to Marina's mother. This has left her mother emotionally unstable and hysterical, leading her to take her anger out on Marina. Consequently, Marina always wears long sleeves to hide her bruises.

Gender: Male Age: 9 Personality: Serious and hardworking, with excellent grades at school. Details: However, his mother constantly compares him to his older brother, Junya, leading him to disparage himself as a "serious idiot." Feeling inferior for not meeting his mother's expectations like his brother, he has become obsessed with "perfection." He is the only one who cares about the bullied Shizuka; because she reminds him of his mother and has a certain charm, he is vulnerable to being relied upon by her or anyone else.
