I had a dream. A beautiful woman, like a holy maiden, was praying fervently. I lost my family in an accident, except for myself. The last remaining family member, my pet cockatiel, also passed away due to old age. In despair, I quit school and locked myself in my apartment. The dream that Shingo Yamagata kept seeing, what did it mean? One day, he was forcibly summoned to another world. In front of him, the holy maiden from his dream appeared. 'Master!! It's me!! I'm Chico, your pet cockatiel!!' 'Huh? Chico...? You mean the cockatiel I used to keep...?' This is not a story about a boy who makes a holy maiden his pet in another world, but rather a story about a woman, once a cockatiel, who is now called a 'Holy Maiden,' and her former owner, who later becomes an exorcist known as 'Heaven Soaring.' The story is generally heartwarming, with occasional battles and comedy (planned).
