In Negima!?, Nekane does gain a greater role in the second anime. As the Star Crystal crisis slowly grows, Nekane chooses to assist her brother by disguising as the "Black Rose Baron", an enigmatic character initially seen not working for either Negi or for the one controlling the crystal. Eventually, Nekane appears as herself to assist Negi and his class in the running of the day-to-day activities, but Negi eventually discovers her secret. However, he is forced to keep Nekane's other identity a secret to protect her and his students.
