Marina

Main character traits
Cruelty and aggression. Marina regularly bullies Shizuka, physically and emotionally: she insults her, turns others against her, and commits acts of vandalism. For example, she even tried to take Shizuka's dog away.
Manipulative. She knows how to influence others, leading a group of friends and using them for her own ends, trying to avoid punishment for her antics.
Charm. Despite her cruelty, Marina possesses a certain charisma and knows how to project a positive image—for example, to appeal to certain people (her boyfriend Naoki Azuma or her mother).
