Sing a Bit of Harmony

Satomi Amano (Haruka Fukuhara) is perfectly fine being alone, until a new transfer student named Shion (Tao Tsuchiya) turns up in her class, an AI who bursts into song and promises to make her happy. Yasuhiro Yoshiura follows the odd company that gathers around Shion, four classmates drawn closer to Satomi by her princess gowns and her musical numbers. Shion stands in the middle of the classroom, mid-song, a girl who does not quite pass as human.
