Magic Swordsman (魔法剣士, Mahō Kenshi) is a unique person able to use swordsmanship and the powers of a Diva (i.e. Summoning Magic) in battle. Otonashi Kaguya had planned on training someone who could use both of these and train them in an attempt to merge both the Magic Division and Swordsmanship Division instead of both divisions being at odds with one another.
Though Kazuki was classified as the first official Magic Swordsman in Japan, Tsukahara Kazuha became a Magic Swordsman due to her being an Illegal Magician though lacking in swordsmanship. However, this changed as she had trained in swordsmanship with Kazuki.
