KO One: Wang Yunxi Can No Longer Hide Her Power

No CP (KO One, The X-Family, and K.O.3an Guo)

When Yun Xi, who has an identity linked to the Time-Space Administration System, unlocks mysterious memories on her eighth birthday and is adopted by the Wang family, the gears of fate begin to turn. On the surface, she is Wang Dadong’s sweet and quiet little sister, but she secretly possesses extraordinary combat strength and an SSS-grade weapon called the Feather Blade.

From the orphanage to Bali High, then transferring from Banana High to KO One, Yun Xi quietly observes those around her as she adjusts to her new family and school life: her parents, former top assassins; her brother Wang Dadong, who only gets stronger when faced with a strong opponent; Wang Arthur and Ding Xiaoyu; and Teacher Tian Xin, whose identity is shrouded in mystery. The wing-shaped bracelet on her wrist constantly reminds her of the mission she bears across time and space.

In this world full of supernatural powers and legends, how will Yun Xi balance an ordinary life with the heavy responsibility the System has given her? As friendship, family bonds, and unknown dangers intertwine, can she protect those around her while uncovering the mystery left behind by the Main System and writing her own story across time and space?
