[Machine Translation] This is the original soundtrack of Innocent Grey's latest work "Heavenly Girl". The title "Caelum" is a Latin word meaning "sky" or "heaven". This CD contains 57 songs based on JAZZ, which are profoundly and delicately crafted. Three-sided case (3 discs + 24-page booklet). Includes a newly written short story "Letter from Her" (52 pages). This short story is a sequel to the main game. Please read it after clearing "Amano Shoujo". Also, this short story is connected to the short story "A Letter from Her" included in the PREMIUM EDITION of Amano Shoujo, so you can enjoy the world more if you read them together.
