Ikkyu Soujun

Ikkyu Soujun is the leader of the I-Jin, and first appears in the second episode. He is romantically involved with at least one clone of Mata Hari; it is assumed he created a second to serve as a spy within the British Library's special operations team. He dies at the hands of Nancy (the one who befriended Yomiko) aboard the rocket at the end of the series
