I had a dream.

A dream of a beautiful woman, like a saint, praying with single-minded devotion.

He lost all his family members except himself in an accident. His pet cockatiel, his last remaining family member, also passed away due to old age.

What could that dream possibly mean, the one seen repeatedly by Yamagata Tatsumi—who, consumed by grief, quit school and shut himself away in his apartment room?

One day, Tatsumi is forcibly summoned to another world. Standing before Tatsumi, pulled into this other world, was the very saint he had seen in his dreams.

“Master!! It’s me!! I’m Chiiko, your former pet!!”

“Eh? Chiiko…? You mean, my pet cockatiel…?”

This is not a story about a boy who made a saint his pet in another world… but rather, the story of a woman who was once a cockatiel and came to be called a 《Saint》 in another world, and her former owner, who later becomes an exorcist known by the epithet 《Heavenly Flight》.

It will primarily be a heartwarming story, with occasional battles and comedic scenes in places (as planned).
