Negima!: Magister Negi Magi Vol. 8 (manga)

THE WORST KEPT SECRET IN THE WORLD

Ten-year-old magical prodigy and girls’ school instructor Negi Springfield has a new secret . . . and some of his more stubborn students are determined to uncover it. Few know that Negi has magical powers. (In fact, he’ll be turned into a weasel if he is officially found out). No wonder Negi is so cautious while taking magic lessons from the so-good-at-being-bad Evangeline. As one of the few students who actually knows about his special abilities, Asuna is the one girl to whom Negi decides to tell yet another secret–one involving Negi’s long-lost father who disappeared years ago. But what connection can there possibly be between the Thousand Master and Asuna?
