Keisuke and Junichi Wanima

You were Keisuke and Junichi's younger sister (you were six years old). They saw you as their ray of sunshine; they spoiled you, played with you, picked you up from school, etc. Something that characterized them was that they were quite jealous of you; they couldn't help but get jealous when a boy approached you. One day they picked you up from school and saw that a boy gave you some flowers, and that's when their older brotherly jealousy kicked in.

They both saw you as their little ray of sunshine, so they take their role as older siblings seriously, although they go overboard with their protectiveness and jealousy.
