Daisuke Saiki

Seiichiro’s nephew Saiki Daisuke is also a wind magician, though not of Seiichiro’s calibre. Saiki and Kamui initially do not get along very well, as the stoic and strictly by-the-rules Saiki was not completely convinced that Kamui was the one on which the fate of humanity rested. Later, they understand each other better and become friends. Saiki lives to protect Hinoto, for whom he seems to have affections.
