Kuttsukiboshi (2010)

To Kiiko Kawakami, there was nothing in the world as important to her as Aaya Saitou. Something about her allured Kiiko to the extent that there was no sound sweeter to her ears than Aaya's voice and no sight more beautiful than her hair softly billowing in the wind. It was for that reason she let Aaya in on her secret: last year, she had gained psychic powers from an accident that changed her life.
