"So you've never lost huh? You defeat all your enemies in one shot. You deflect all attacks away. People like you wouldn't know how to street fight."
— Touma Kamijou, to Accelerator, A Certain Magical Index Episode 14
"[Steilman] doesn't know how to fight. Not for real. He's never had to learn, because he is big and strong and mean."

San Francisco is a big karate town: in 1965 there were roughly seven thousand full-time fee-paying karate students roaming around the Bay Area... but in any active bar you can hear a story about a bartender who 'busted up a guy who tried to pull some karate stuff.' It hardly matters how many of the stories are true. The point is valid: the difference between survival and wipe-out in a physical crisis is nearly always a matter of conditioned reflexes. A bartender with scar tissue all over his knuckles will hit faster and harder than a karate-trained novice who has never been bloodied.
