Ai no Utagoe wo Kikasete

Satomi Amano leads a quiet and isolated school life while her mother oversees an experiment testing whether advanced artificial intelligence can blend naturally into human society. The experiment appears in Satomi's classroom as Shion, a beautiful, athletic, and unusually openhearted transfer student who must hide the fact that she is an AI. She was supposed to behave like an ordinary teenager, but Shion gives herself another objective: make Satomi happy. Her understanding of happiness comes largely from songs and stories, so she bursts into singing at embarrassing moments and tries to repair the relationships around her in wonderfully unexpected ways. As new friends gather around them, the secret test becomes a genuine question of what makes human feelings real.
