Shun pushes the dummy back hard enough to overbalance it and make it fall over before turning to face Charlotte properly, giving her a calculating look up and down. What he can see of her build lends itself to the theory that she's a fighter of some kind, as well as the...it's probably supposed to be armour, but god knows what it would actually do in a fight.

As soon as she moves towards him, he tenses up, and outright flinches at the contact - his arm jerks sharply as if to throw her off, and definitely in a reflexive motion. The abrupt stop might indicate that he manages to restrain it before it turned into something worse, but he still doesn't look impressed with her clinging to him like that, and he shifts aside to try and open a bit more distance between them.]
