Nobody knows if he was born a Wisp or became one. He doesn't talk about it. But he reads the System's currents like no one else.
He doesn't fight the tide. He reads it. And in those readings, he finds the gaps where his crew can move unseen.
Blu senses when the System is about to look, when sensors will sweep, when a window opens. When he manipulates the system it's fluid - barely any traces left and smooth like water.
Timing, not force, it's the core. He rarely runs the job himself. He calls the window. He knows the crew. He connects people.
The constant the stories return to. BluAqwa is coordinator of the Counter-Current. Never the hero. He's the one holding all the threads.
