[Brain lifts his wrist to take a look at his watch, starting to go through the profiles.]

According to the profiles, only Alastor has swordplay listed, and John and Gai have weapons listed, however that's hardly an inclusive list, seeing as there are also things listed as enjoying seeing people die, in Hermes' case, or enjoying martial arts. I'm aware that Makima has a sword, but that is also not quite an indicator, considering how easily accessible swords are thanks to the weapons room.
