Aika Natsukawa

Aika has emerald green eyes and bright orange hair with bangs which she keeps open at school with a side braid at the left side. She is beautiful and very cute in appearance, as pointed out by many in the story. Aika appears to be a cute, diligent and friendly girl and is adored by her classmates. She is hardworking and gets frustrated on not being able to do good enough. She often comes off as harsh when dealing with Wataru but is actually kind and caring. She never used to be interested in matters regarding love and thus finds it difficult to understand and deal with romantic stuff. In middle school, Aika's parents used to be busy with their jobs and their financial condition wasn't very well. Seeing their hardships, Aika took it upon herself to do the household work and taking care of her little sister which gained her a dedicated, diligent and hardworking personality. She studied meticulously and got enrolled in a prestigious high school, Kōetsu High where she eventually got followed by Wataru.
