To Kiiko Kawakami, nothing in the world was as important as Aaya Saitou. Something about Aaya drew Kiiko in so deeply that no sound was sweeter to her ears than Aaya's voice, and no sight was more beautiful than her hair gently billowing in the wind. For this reason, Kiiko confided in Aaya her secret: the previous year, she had gained psychic powers from an accident that changed her life. Kuttsukiboshi is a story of infatuation and romance between two girls as their feelings for each other reach a tipping point. Unable to deny their heartfelt desires, the two give in to them and create many sweet memories together around the school—testing the limits of Kiiko's powers and how far they can go without being discovered during their trysts. However, will things remain as they are when Kiiko discovers that the love of her life has a dark secret of her own?
