A soul was employed by a higher being to help him manage his world. How will our protagonist live her life to the fullest while also fulfilling her new duties?I don't own Naruto. I adjusted the story to my liking. English is not my main language so don't bother about grammar mistakes too much.

The ancient Divine Beast Susu descended to endure trials and became the youngest daughter of the Qin Family, who were nearing eighty years old; young in age but high in seniority, even the men in their twenties had to call her auntie.Susu was also the only girl in three generations of the Qin Family, cherished by her parents, doted on by her brothers, and her nephews would fight over holding their auntie and protecting her.Protect her? Susu said she didn't need it, for she was a mighty and ferocious Divine Beast!With her around, no one would dare to bully the Qin Family members!Those who bullied her family got sent flying; those who coveted their fortune got sent flying; those who tried to kidnap her got sent flying.The kidnappers who captured Susu were frightened by her and willingly handed over their cell phones for her to call the police.“How do I unlock the cell phone?” Susu asked.“It requires fingerprint unlocking, you can use my finger,” explained the kidnapper.“How do I use your finger? Chop it off?” Susu asked again.“No! No need to chop, it can be used while still attached to my hand!” the kidnapper wailed.Chop off a finger! What kind of thought process was that?Way too scary!Ever since the lucky-buff-carrying Susu had come to their home, the family's luck had improved, their business prospered more each day, and the previously naughty young masters had become much better behaved, truly a little lucky star.It was just that boy from the neighbor's house, who kept thinking about kidnapping Little Susu, causing the Qin Family men quite a bit of concern.Maybe they should just break his leg again?
