Honestly, Luna hasn't had this much trouble with being picked on by kids in years. Her time with Usagi and the other Senshi didn't count seeing as how none of them would do this sort of thing to her. She'd say it was a human trait but it's already obvious that she isn't on Earth anymore.

At the moment, she's chosen to not speak out and reveal herself to these ridiculous children but Luna is all about trying to defend herself. While the feline is not particularly interested in using her emotions to scare them off, she's certainly putting her natural defenses to work - biting and scratching.

When a familiar voice started to yell and the ground began to shake, the entire group froze and turned to look at the individual responsible. Luna is so extremely glad to see the blond and took advantage of their shock to bite down on the hand that's wrapped around her tail to get the boy to let it go and she darted away.

Of course it's only natural for her to head straight for Usagi, to leap straight up from the ground to land on the girl's shoulder and peer around that blond hair to glare at the kids.
