Iga Suru was a member of a minor vassal family of the Shiba who became a powerful maho-tsukai known as Jama Suru. He was also the first to pledge his soul to Iuchiban's service, and it was rumored that Jama Suru was the one who introduced the intricacies of maho to Iuchiban. Bound to a kansen, he had been killed many times, only to be reborn again.
