We, alone in this world.

In this world, we were "alone"───. The "Door Person" is a hero blessed by a benevolent god, possessing the power to erase the "distortions" that arise in the world. The one who becomes the mother of this Door Person is a "Rare Person." Brought from modern Japan to another world by such a prophecy, the woman Miharu Hiyori escaped to the sky, transformed into a bird using magic she learned while fleeing from people whose intentions to seek power and malice were transparent. However, she is shot down from the sky by a white hunter with opalescent eyes. A person from another world and the last survivor of an extinct race. This is a story of their encounter—two lonely souls. *Also posted on pixiv under a different name.
