Changed

Leo and Air are best friends until the first year of high school when he chooses football over thier friendship. In the middle of the night Air goes missing.
3 years later Leo moves to a "less then modern"school. There he sees Air but she is not the geek he once knew. She is practacly running the school.The closer Leo trys to get to Air the more he discovers the pupils in this school are not your typical teens.
Air has no time or interst talking to her ex best friend Leo. She has far bigger problems to deal with and the less he gets involved the better.
Airs gran however sees a war coming and the only way through it is for these two to work together. For the sake of peace both must learn how to cooperate and forgive.
