Sing A Bit Of Harmony (PG)

Satomi Amano is a loner at Keibu High School. Her sense of isolation slowly dissipates when new girl Shion Ashimori transfers to the school and endears herself to her peers with exceptional athletic abilities and boundless good cheer. Shion breaks into song without warning and her focus seems to be on sullen Satomi. It transpires that Shion is an artificial intelligence in the testing phase, whose primary objective is to make Satomi happy.
