As he was fleeing the area, the older woman, Gertrude, who was the leader of Blessing in the stronghold Hotel since their leader was back in Ward, got Mika's distress signal. She frowned, but reacted quickly since she knew that their members would only press their alarm if their lives were in mortal danger. His location popped up on her bracelet, but that only lasted for a few seconds before it disappeared. Followed by a massive explosion.
It took her 20 minutes to gather up 20 blue core rankers, both beasts and humans. That number also included her personal security, of which there were 5 blue cores. The rest were just added muscle. She only got to see where he was located for a few seconds, and she was almost certain that was where the explosion came from.
