The luckiest girl is not one who is loved by thousands of people when she is born, but one who survives a disaster even if she falls off a cliff when she is still in her infancy; the luckiest girl is not one who is adopted by a good family and brings good luck to the people around her, but one who is thrown into a land of fireworks by her stepmother but is rescued by an expert and grows up in a pure land; one who has the luckiest girl is one who does not have an all-powerful appearance and unparalleled martial arts, but one who has the right person to stay with forever...
To put it simply, this is a story about a cute girl with strong martial arts skills who goes around looking for relatives.
