Alfonse

A prince of the Kingdom of Askr—the setting of the story—and the wielder of the divine weapon Fólkvangr.

He belongs to the Order of Heroes, a special task force that harnesses the power of heroes from other worlds, and works alongside its commander, Anna, and his younger sister, Princess Sharena, to safeguard the peace of the realm.

While opposing the forces of the Emblian Empire—led by Princess Veronica, who had suddenly launched an invasion of Askr—he encounters the Summoner, the protagonist who has been summoned from another world.
