Kansuke

Rasetsu (羅刹) was a bandit leader fifty years before the start of the series during the original tragedy of the Shikon Jewel which ended in the death of Kikyo, the sealing of Inuyasha and the birth of Naraku. Rasetsu, who was originally known as Kansuke, lead a group of bandit thugs which included a man named Onigumo. After being tricked by Onigumo into attacking the priestess Kikyo in an attempt to acquire the Shikon no Tama which ended in Rasetsu's defeat at the hands of Inuyasha Rasetsu sought to make the man who had tricked him and stolen his men pay. As Onigumo and the rest of the bandits who declared him their new leader celebrated at a local inn Rasetsu planted a bomb which exploded leaving Onigumo severely injured. To finish the betrayer off the men threw him off a cliff.

Fifty years later Rasetsu, now an old man, met the revived Kikyo not realizing that she was the same Kikiyo he had tried to kill decades earlier. The man is later attacked and killed by demons but before he draws his final breathe Rasetsu asks Kikyo to take his remains to the sacred Mount Hakurei. Naraku had filled his heads with thoughts that he would be properly salvated if his remains were taken to Mount Hakurei. But instead it was Naraku's plan to lure Kikyo there so he could test out if he could kill Kikyo and that Onigumo's heart would not stop that.
