I'm Yatos Shinki. My name as Shinki is Sekki (器 器), my form is that of a Katanas. I died very young, which is why i missed my normal life as a middle schoolboy. I'am behaves according to my age and i can deal with this situation bad. Several times i stole, since i was already dead and therefore everything doesn't care. But every time i sins, Yato suffers. Although Yato is my master, i showed him less respect than iam actually feels for him. After i was saved by Hiyori, i became more obedient to Hiyori and Yato.
