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.
In this week's Noragami Aragoto, Yato is on his way to save Hiyori. He has no clue where she is, but he has an idea who is keeping her. He is ready to save her, even if its means putting his own life at risk.
Noragami is set in a really immersive and unique world full of gods, monsters and wandering spirits. It is filled with great quotes that will make you think about life and death in a brand new way that you’ve never even considered before.
