Asano Naganori
As a "kōke", Kira oversaw matters of protocol. In 1701, he was assigned the task of tutoring Asano Naganori in matters of protocol in preparation for an upcoming visit by representatives of the Emperor. According to the stories, Kira was corrupt and demanded bribes for the tutoring, which Asano refused to pay. Kira then began to publicly insult Asano, calling him an ignorant and unmannered rural boor. On the day when the envoys were scheduled to meet the shōgun at Edo Castle, Asano drew his wakizashi and attempted to kill Kira in retaliation for the insults. For this, Asano was sentenced to commit seppuku, his house abolished and his retainers branded rōnin, while Kira went unpunished.
