Just because Kujen can't feel the pain doesn't mean it doesn't affect his body - Eiffel screams in his brain, breathing shallow as agony rushes through his system and his knees would buckle if Kujen didn't have such tight control, nausea swells and the acidic taste of bile rushes up his throat, threatening to overwhelm and escape.

But Eiffel... gives off a tiny flicker of satisfaction. So he can try harder. And his body's weakened, with the shock, so maybe...

Darken the city, night is a wire! Steam in the subway, Earth is afire, Do-do-do-do, do-do-do, do-do, do-do-do, do-dooooo--
