It is the story of a Saiyan warrior "Kyuri" with a painful past whose main strength is rage.
Originally from Universe 7, she comes from an era more than 1000 years ago and has been brought back to the world of Kaïo Shin of Time where she meets a Trunks (from the future) still marked by her failure against Zamasu and the destruction of her world as well as her daughter Shibie whom many consider a true princess (because she is very beautiful), 12 years old and who dreams one day to meet her grandfather (the proud Prince Vegeta).
She quickly became Kyuri's best friend, almost a spiritual sister and trained together to counter the Time Breakers' plans.
But Kyuri's real motivation (one could even say an obsession) is to surpass and become better than Son Goku.
