Ep. 23: Negi faz um Pactio com Evangeline para contra-atacar o ataque de pedra de Evangeline

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.
