The Awakeners and Hunters Council had planned to destroy the Kiss of Death before the gate explosion case occurred. However, they had to postpone the plan because of a bigger problem. They would use their best people to take care of the emergency meeting.
As a result, they were forced to free Kiss of Death because they could not send inexperienced people to set up an ambush. The IRO had also predicted the evil organization would mess up at the emergency meeting.
The evil organization that dared to challenge the IRO was only Kiss of Death. Others would not dare because powerful people would gather in the conference hall. Tyrone's power frightened them. That was what made the IRO not reveal the news of his attack.
They were worried the evil organization would move when they found out that Tyrone could not use his power. Nevertheless, Kiss of Death sent threats to the IRO blatantly. They would not dare act like that without having some guarantee.
