Kate with her li'l kiddos, going trick-or-treating! They love the fact that their mom has the best costume out of everyone's parents, since she doesn't even need to dress up for it, she can just turn herself into a monster! That's so cool!
She also loves the opportunity to put her Infernal abilities to work, in a context that isn't about fighting people, and Devil Tyrant Avatar Shintai is perfect for putting on a spooky look. Plus, she can't resist the opportunity to dress Marta and Marek up like her own first couple of pokemon XD
