When it was recently pointed out to me that Maisy, with her costume changing, not-really-so-secret identity, and super "finishing move" attack, could pass for an anime "magical girl"-style hero, I realized she didn't have a special weapon. I mean, even her sister, Zoe, has her Atomic Claymore, so I was seeing how Maisy'd look with her own "super weapon."
...offhand, she seems to like it.
