If you wanted even more Negima for your money-- and yet were also planning to import the Mahou Sensei Negima! ~Mou Hitotsu no Sekai~ OVA from Japan --good news! A bonus episode is reportedly being included in the OVA release that features the Ariadne arc.
I'm not going to pretend that I know what the Ariadne arc is, but it apparently involves Yue, who was one of approximately two characters that I actually like in Negima (the other one being the ferret). So, rock on!
