Tensei shita Dai Seijo wa, Seijo de Aru Koto wo Hita Kakusu ZERO

In the Kingdom of Nave, a six-year-old princess has lived her entire life without sight. To shield her from the treacherous political disputes that plague the royal court, the king made the difficult decision to raise her far from the capital, hidden away in the secluded sanctuary known as the Forest of Lent. Despite her youth and blindness, this young girl harbors an extraordinary power, living quietly beyond the reach of those who might exploit her lineage or abilities. Now, the time has come for the princess to return to her rightful place. Recognizing the dangers of the journey and the magnitude of her latent strength, the king entrusts this critical mission to Sirius, the formidable vice-captain of the Unicorn Knights. As one of the kingdom's most powerful warriors, Sirius is dispatched with a single, unwavering directive: bring the princess home safely. What begins as a straightforward escort mission soon evolves into something far greater when the kingdom's strongest knight finally comes face to face with the young saint he was sent to retrieve. As they navigate the path back to the capital, Sirius must protect a child whose hidden potential could alter the fate of the realm, forging an unlikely bond between unmatched martial prowess and quiet, miraculous grace.
