Ai no Utagoe wo Kikasete

When the striking and enigmatic Shion transfers to Keibu High School, she immediately captures the attention of her peers with her warm demeanor and remarkable athletic abilities. However, there is a secret behind her charm: she is actually an artificial intelligence currently undergoing field testing. Her primary directive is to bring happiness to Satomi, a chronic loner who keeps to herself. To accomplish this mission, Shion employs a strategy no human would ever consider—bursting into spontaneous song in the middle of the classroom to serenade her bewildered target. Once the truth about Shion’s nature comes to light, Satomi and her childhood friend Touma, a passionate engineering enthusiast, gradually begin to accept their unusual new classmate. They are soon joined by a lively circle of friends, including the handsome and popular Gocchan, the fiercely determined Aya, and the judo club member known as "Thunder." Together, they find themselves increasingly touched by Shion’s heartfelt singing and unwavering sincerity, even as her unconventional behavior leaves them baffled. Ultimately, Shion’s relentless efforts on Satomi’s behalf draw the entire group into a whirlwind of chaos. What follows is a deeply heartwarming tale of friendship, music, and the unpredictable journey of an AI who is not quite ready for the real world.
