The protagonist awakens in a hospital, having lost all of his memories.

Confused and unable to recall even his own name, he is approached by a mysterious boy named Rui.

Rui claims to be a relative and tells him to call if he ever needs help—then disappears.

Thanks to the kindness of Kaname Asayama, whom he befriended during his hospitalization, the protagonist moves into an apartment run by the Asayama family. Hoping to uncover his past, he heads into the city in search of Rui.

Though his memories are gone, he believes that slowly reclaiming a normal life might be enough…

But that fragile peace is shattered when he is confronted by a group of men in the city.

To his shock, they attack him using supernatural powers known as Esper abilities. Overwhelmed by fear, the protagonist awakens to his own power—the ability to Summon.

The summoned girl, Aviore, looks at him and declares

“Prince! You’ve summoned me at last!”

And so, his brief return to ordinary life comes to an end.

The boy is thrust into battle.

This is the story of a young man who fights to protect the Earth.
