A variation of a personal Skill of Archimedes, the founder of mathematics. Archimedes accidentally created massacre weapons that surpassed the state-of-the-art weaponry of his time, but Koyanskaya gained this Skill on purpose. The Skill allows her to use any weapon used by Humanity from the era she's in, and the weapons become multiple times more powerful than they were in human hands and able to instantly perform the natural cycle of retributive justice (karma normally takes it slow, occurring liberally through the span of a few centuries). Fitting for a former Beast in the making, this Skills represents the fact that, on paper, humanity doesn't stand a chance against her in this era. That said, this Skill serves only to assert dominance on humanity, so it's not nearly that absolute of a Skill against Servants or Monsters. It gives her a disgustingly powerful super-effectiveness against humans.[1][2]
