Kokoro no Program

A boy named Kyu meets a robot girl named Ichiko. Two gears that were never meant to mesh begin, at last, to turn. During summer vacation, Ichiko, a robot girl almost indistinguishable from a human, comes to live with Kyu Usami, who lives alone with his mother. As Ichiko sets out to learn what it means to have a “heart,” Kyu finds himself increasingly drawn to her. Meanwhile, his childhood friend Ai harbors feelings for Kyu of her own. Emotions slowly grow, intertwine, and begin to tangle together… Boy meets robot girl. The curtain rises!
