Minato Nagase

Minato Nagase (長瀬 湊(ながせ みなと) Nagase Minato) is Jun'ichi Nagase's younger sister who attends the same school that he does as a first year high school student. She is capable in all areas of household related work and is proud of it. She also has unique abilities, like listening to the ground to detect the presence of animals, as well as being able to communicate with them. She has feelings for Jun'ichi, but can't bring herself to admit it. She mentions that she was adopted once, but later says it was a joke. She and Jun'ichi end up believing that they are indeed blood-related, although the parents make a comment at the end of the series hinting that they are not.
