Ai no Utagoe wo Kikasete

A new student named Shion joins Keibu High School and gains attention for her cheerful attitude and athletic skills. Unbeknownst to others, she is an artificial intelligence undergoing testing. Her mission is to help Satomi, a socially isolated student, find joy. To achieve this, Shion uses an unusual method—singing to Satomi in class. After discovering Shion's true identity, Satomi and her friend Touma, who is interested in technology, gradually grow closer to her. Other students, including the well-liked Gocchan, determined Aya, and judo club member Thunder, are also drawn in by Shion’s sincerity and singing, even as her unpredictable behavior confuses them. As Shion continues her efforts to help Satomi, her actions lead to increasing chaos that affects the entire group.
