[Meanwhile, as the main island is overtaken by celebrations, there's something entirely different going on in the smaller islands. Frustrated and really, really pissed off by this place messing with Sherlock's mind, as well as shaken and annoyed by her recent encounter with Yuuki, Jamie was already in a state of mind where she thought killing people might seem like a bright idea... and after she was finally attacked by a monster that took her discretion, well, suddenly killing every single native Kisekian, as well as every monster she sees, it's more than just an idea.
Which is obvious, should anyone decide to run from the party hats and celebrations to the other islands, as there will be dead Kisekians in shops, the hotel receptions, the attractions, and so on. And of course Jamie herself, a gun in her hand and blood on her clothes, seeming entirely unconcerned about everything.]
