Aya is the younger one from the Natsume sisters and is studying first year in the Todo martial art school. Once, as she is having a shower some boy falls from the ceiling. There is a tradition in her family that every woman must marry the one she reveals her skin to. Aya falls in love with that stranger, who collapses from the ceiling, and decides she must get married with him. No matter where he goes she is fallowing him. She brings him home made food; shares with him an umbrella under the rain and always finds out where he is hiding. This obsession of hers is darkened by some doubts she has about the relationship her “fiancé” has with her sister. Comparing herself with her big sister she seems insignificant. Aya doesn’t have her skills, and in everything else her sister is superior. This is why she wishes to become stronger. Indeed, she has a lot of potential and often “the dragon eyes” speak from within her. Her biggest wish is to become better than her big sister and not to loose her beloved man.
