It's Time to Run When... Karou screams and begins using her wooden sword Kenshin's eyes turn yellow Kenshin's eyes and scar begin to glow Kenshin flips his sword Anytime you comment on how bad Karou cooks When Sano throws Yahiko through the air Anytime Yahiko and Karou are fighting (which is almost always) Kenshinn stops adding "that it does" or similar statements to the end of his sentences Karou makes hints that you're going to pay for dinner Anyone starts talking about a manslyer being on the loose Anytime Karou cooks When Kenshin's eyes turn from their normal color to yellow to red (you'd better run twice as fast)
