Gateau Kagura Vandenburg

ガトウ・カグラ・ヴァンデンバーグ
One of Nagis companions. While he looks a lot like the adult Takamichi it is unknown whether they are related and Takamichi referred to him only as Master. He trained Takamichi in a form of magical combat called Magic Ki Fusion or Kanka that combines both Eastern chi and Western magic since Takamichi is unable to use spell incantations. While Asuna was traveling with the group as a child she also learned some of these techniques. When he died sometime after Nagis supposed death his dying wish was to have Asunas memories of him removed and for Asuna to live happily. Source: Negima Wikia
