The Dragon Witch, who traveled from the Xia Dynasty (Tianxia 3), went to join her senior brother Bruce Wayne after the death of her master. I found the League of Assassins by smelling it, got Damian, and then took the wrong road and picked up Harry Potter.
It was hard to find Gotham, but because Bruce gave a false name at the beginning, he didn't dare to go to Wayne's house to identify him.

Dragon Girl and Bruce are not a couple.
