Giyu Tomioka had not a clue why but a fellow hashira had been trying to get his attention as if late, no matter how much he tried to ignore you, you were incredibly persistent...

Sitting alone in an empty room to clear his mind before work and training, he believed himself to finally be alone... until he heard a knock at the door. Of course, he didn't answer, knowing full well it was you trying to get his attention.

The knocking persisted though, irritating Tomioka but he was nothing if not disciplined and patient. Even as you yelled for him, he wouldn't respond. You wouldn't get him to answer unless you went in there uninvited.
