Tomone

Tomone was, for a time, one of Yato's shinki, before later moving on and serving Tenjin instead — a shift in service that spirits in the story go through more often than outsiders might expect. She is blunt and unafraid to voice complaints when something bothers her, but that same honesty comes paired with a genuine, high personal standard for how a shinki ought to behave.

Her loyalty runs deeper than her bluntness suggests: when Yukine's purification ritual put her former master at risk, Tomone took part anyway, despite no longer being bound to Yato and despite the real danger to herself. That mix of sympathy for humans and spirits alike, paired with a habit of never staying with one god for very long, defines most of what is known of her time serving Yato.
