H2O: Footprints in the Sand

Takuma Hirose, a boy left blind with no diagnosed physical cause, moves to his uncle's home in a rural village to recover. There he meets Otoha, a cheerful girl only he can see and hear, who offers to restore his sight, and Hayami Kohinata, a withdrawn classmate the rest of the village pointedly shuns. As Takuma keeps reaching out to Hayami despite the cold treatment, he begins to stir up the buried grudges that hang over the village.
