That ending where futo talked to miko reminds of the king of yue,goujian, who got defeated and was forced to be a slave to the king of chu,fuchai during the warring states period of china.The hardships he endured when as a slave and eventually defeating his master and restoring his state honor was so great,there is an idiom that roughly translates to sleeping on brush wood and tasting gall which means to suffer to achieve greatness.(Sorry for making this a long comment)
