Totsuzen Kishi ni Natte Mufufu na Ore ga Iru

At the command of his father, Kazehara Minato is suddenly tasked with becoming a knight, a role he had never anticipated. As part of the process, he undergoes a ceremony that unexpectedly draws the attention of the princess, a figure whose presence is as rare as magic itself. Motivated by the desire to continue observing her—and later, to ensure her safety—Minato resolves to train and develop into a capable knight.
