Ibuki

Ibuki (忌ブキ) also known as 'Child of the Contract', who is the designated heir to the Throne of Nil Kamui as acknowleged by it's guardian diety, the Red Dragon and is the protagonist of the series. Ibuki is one who hates violence and is seen attempting to prevent it in the beginning of the story, but over-time he slowly accepts that violence is needed to resolve the problems of Nil Kamui. He is refered to as 'Lord Ibuki' by Fugaku, a loyal retainer of the previous monarchy. He is the representative of the Revolutionary Army in the Red Dragon Expeditionary Group. After, a massacre by Lady Koukaku's Army (Kouran) which resulted in the deaths of large numbers of Nil Kamui's citizen being killed, Ibuki slowly starts to accept the position of 'King' within Nil Kamui to prevent such a thing from occuring once again and to honour Mashiro's dying wish. Eiha is Ibuki's Personal Guardian. The Revolutionary Army accepts Ibuki as the legitimate King of the Land or seemingly so until Inori is revealed. As a Koutoushu, his ability is that of offering up a soul in turn for taking another as is seen when Ibuki unintentionally offers up Mashiro in turn taking one of Lady Koukaku's subordinate's life.
