The third daughter of the Isumi family. Marika grew up watching her two older sisters fight often, leading to her being a harmonious person, trying to avoid taking action in any conflict and being disliked by either one of them. She learned how to read how others feel, especially those close to her. She's cheerful and animated, but is overly conscious of other people's feelings, preferring to keep how she really feels to herself.
Marika is also very athletic, smart and popular at school. She's the only one of the four sisters that's the same age and goes to the same school as Masaki, giving them a unique relationship that isn't fully anything. Masaki is the only one she tends to be an open book with, even more than her family.
