THE POWER OF FATETota meets Kirië Sakurame, a mysterious member of UQ Holder. Kirië looks like a little girl, but is apparently the wealthy patron of UQ Holder. Tota accompanies her on a trip to the tower to meet Karin (returning from the Moon), but the trip appears to have another purpose. The powerful wizard Fate Averruncus, former ally of Tota's grandfather Negi, wants to take possession of Tota for reasons unknown. Despite having Karin, Ikku, Kirië and Kuromaru with him, they stand little chance of stopping Fate, who possesses unfathomable power. Why does Fate want Tota? And can Kirië's secret plan succeed in stopping him?
