Season 1

Kiiko Kawakami is a high school girl who secretly has telekinetic powers. The only person who knows of this is her friend, Aaya Saitō, who she has a crush on. One day after Aaya helps train her to use her powers, Kiiko leans in to kiss a sleeping Aaya, but she is surprised to find her taking the initiative and kissing her back. The two decide to have a risky rendezvous inside the empty school, and spend various summer memories together having sex in different places where no one knew about their love for each other. One day though, when Kiiko leaves her cellphone at Aaya's house after sleeping over, she returns to find Aaya having sex with her brother, Kōta, who is a famous artist.

Aaya kidnaps Kiiko and keeps her in the gym storage and rapes her after learning what she did. After being let go, Kiiko is still unwilling to forgive Aaya. Some time later, after Aaya learns of her brother's death, she brings Kiiko to her house, asking her to make love with her one more time before she leaves Japan. That night, Kiiko gets a glimpse of Aaya's memories in which she learns that Kōta had a terminal disease and manipulated Aaya into having sex with him before his operation, where he died. As Kiiko realizes the truth and finds Aaya is gone, her powers bring her straight to her, now knowing she can teleport and look into the past and future, and where she expresses her desire to have Aaya by her side forever. Reconciling their feelings, the two warp away together off the plane and end up on a distant planet where they express their wish to spend their lives together.
