Tập 23: Negi lập giao ước Pactio với Evangeline để đối phó với đòn tấn công biến người thành đá của cô

23

Anya, possessing Evangeline through the Star Crystal, turns Asuna against Negi and many of his allies into stone. But with the help of his remaining students, he's able to defeat her by making a Pactio with the vampire, which, alongside Chachamaru, completes his Pactio collection but does not get them out of trouble.
