It's entirely possible Kawaki could've taken it from Kara, or he is a part of Kara.

We know there is more than two mark's, so, yeah.

Also, considering he's on the front cover poster, it's safe to say he's going to have a rather relevant role. He also looks the more cunning on the two, based on his smirk alone. I doubt he's dead or defeated, and he may actually appear with Momoshiki and Kinshiki.
