Premieres July 2025. Check out the ANN article for additional information. Synopsis for the source novels from AniList:
Naofumi Iwatani, an uncharismatic Otaku who spends his days on games and manga, suddenly finds himself summoned to a parallel universe! He discovers he is one of four heroes equipped with legendary weapons and tasked with saving the world from its prophesied destruction. As the Shield Hero, the weakest of the heroes, all is not as it seems. Naofumi is soon alone, penniless, and betrayed. With no one to turn to, and nowhere to run, he is left with only his shield. Now, Naofumi must rise to become the legendary Shield Hero and save the world!
Also the Queen runs the kingdom.
But you know, from the shadows or something. Because that’s how power works. Ignore the king and how it wrecks a lot of plot points.
Like when Melty revealed herself to be a princess and direct agent of the Queen I just gave up on this anime.
Its a lot of weird angst and weird messages here that never made sense to me.
