The male protagonist of Blue Star traveled through time and became Kalifa. At the beginning, she forced Lao Sha to hand over Feng Clay. After obtaining the imitation fruit, she continued to develop the fruit, and then imitated the abilities and physical skills of strong men from all walks of life, fighting Kaido, killing aunts, and beating up the five old stars until she became the true overlord of the sea.
The tone of this book is rather dark. If you don't like it, don't read it. It has almost no interaction with the protagonists.
