Hinako is a first year high school student in Homurahara Gakuen, located in a beautiful town nestled between the sea and the forest, Fuyuki city. She is a scholar student, receiving a full scholarship grant with an IQ of around 155. Her high school days would have been normal, if it wasn't for her accidentally crossing the line with the SC's Vice President, Gil (played by Gilgamesh; Fate/Stay Night, UBW, Extra). Since then, her whole world revolved around him and it wasn't getting better. Will it be the start of a grand rivalry between the two? Or will it become something else as her story progresses?
