Frowning slightly, Haruko notices that Jericho's ki signature is close to her's. With a person this close to her, Cavaler could potentially find her as well, ruining her entire plan. But hopefully that wouldn't happen, as it seemed like her opportunity has arisen.
"With the End of Light I smite you intruder!" Came a voice that boomed across the entire room, with the pillars distorting it slightly. However, Haruko read that Arsenal's ki signature was on the move, and that the voice vaguely came from that direction, indicating that the path in front of her was finally clear. Sticking to the walls still, Haruko moves from pillar to pillar, hugging the side not facing the direction Arsenal and presumably Cavaler were fighting on. She was already 2/3 of the way through the room, so after passing 3 pillars, the battle seamstress finally came across the doorway to the next room. Quickly, she dashes across the floor, running through the doorway and ducking behind the wall behind it. If she wasn't spotted, Haruko would wait until she felt Cavaler's presence fighting another one of her allies again before attempting to climb the stairs in front of her.
Just to be safe though, she places a tripwire at the entrance to the doorway lined with a special string that is detectable through ki control, but extremely hard to spot normally. If this string is tripped, Haruko would know that Cavaler had found her and that she needs to be prepared.
