Aozora Haruka

As the granddaughter of the school director, Haruka was born and raised in the pristine natural environment of Eiden island. With a warm-hearted and energetic disposition, her natural innocence has long since captivated the hearts of those around her.

Being not very well versed in the outside world, she often appears to be clumsy or obtuse, leading to her claims that "my good point is my health!" despite consistently testing into the top of her class; especially on the subjects of math and science. Recently she has taken an interest in the newly transferred boys.
