Kazuma is one of Bishamonten's Divine Instruments (shinki) and her exemplar.
Weapon Name: Chouki
His shape as a shinki is a flower-shaped earring, as which he is capable of tracking enemies. He is the last survivor of Bishamonten's old shinki, who were killed by Yato because they were possessed by demons. He asked Yato to kill Bishamonten's old shinki without her knowing, in order to save her.
Later in the manga Kazuma asks Yaboku to give him a name, making him a Nora. Yaboku calls him Kazune.
