Ibaragi
Ibaragi is a rather young woman that acts as the right-hand mistress of her master, Shutendouji. Ibaragi has a rather kind personality, and vows to forever protect Shutendouji, even when being regularly beaten by him. Ibaragi is first featured within episode 4 when she had been sent by Shutendouji to spy on the Capital, in which she had been noticed by Usui Sadamitsu. Ibaragi is later shown when Shutendouji attacks the Capital, in which she had attempted to convince to him that his actions were barbaric, and he should instead try negotiating with the people of the Capital instead. Shuten responded by beating her, along with abusive talk.
Minamoto no Hikaru and the others later battle it out with Shutendouji, in which Ibaragi performs a minor battle with Sadamitsu. After Shuten then wished to pour all of his swamp-water like sake over his body, Ibaragi attempted to stop him, but was fatally slashed by Shutendouji's sword. Ibaragi, very much near death, delivered the final blow to Shuten, then revealing to Raikou of Seimei's deceit before finally dying.
