Biography
Master Dog's ninja weapons created by Lady Lotus Blossom's blacksmith father
There is little known about Lady Lotus Blossom other than her rescue by Master Dog, though it is unknown what kind of trouble she was in or why. As a reward, Lady Lotus Blossom's grateful father, a traveling blacksmith skilled beyond measure in his artisan craft, made him a set of ninja weapons, which he had wept into with tears of gratitude during the forging of the blades.[1]
