Tened, a mercenary wandering the world in search of his missing younger brother, one day discovers a clue linking his brother to the Grand Cathedral. To uncover the truth, he joins a carriage escort mission bound for the cathedral, but the mission quickly descends into chaos when heretics attack.
Amid the flames, inside the carriage meant to hold a sacred relicāthere is not a relic, but a child.
Without hesitation, Tened rescues the child, and from that moment begins a journey to bring them to the Grand Cathedral. Along the way, in the childās eyes, a nameless feeling toward the man who saved them quietly begins to bloom.
