Sing a Bit of Harmony

When the enigmatic and striking Shion transfers to Keibu High School, she immediately captures the attention of her peers through her warm demeanor and remarkable athletic abilities. However, a startling truth soon emerges: Shion is actually an artificial intelligence undergoing a live testing phase. Her primary directive is to bring happiness to Satomi, a chronically isolated student who keeps entirely to herself. To accomplish this unconventional mission, Shion employs a strategy no human would ever devise—she spontaneously bursts into song right in the middle of the classroom, serenading Satomi for everyone to hear. Once the reality of Shion’s artificial nature comes to light, Satomi and her childhood friend Touma, a passionate engineering enthusiast, gradually begin to accept their unusual new classmate. Their small circle expands to include Gocchan, an attractive and well-liked student; Aya, known for her strong will; and Thunder, a dedicated member of the judo club. Though Shion’s eccentric behavior frequently leaves them bewildered, the group finds themselves increasingly touched by her beautiful singing voice and her genuine, unwavering sincerity. Ultimately, Shion’s relentless efforts to fulfill her mission for Satomi draw all of them into a whirlwind of serious pandemonium.
