"How can you not know a lock-picking jutsu?" Asuma demanded, twisting to study the painted seals in more detail. "That's like ninja 101." Ink-black kanji rippled over the walls and ceiling, even the grating bars, dark and quiescent now no one was trying to cast a jutsu. He reached up and scraped his nails over the nearest one, but it didn't make a mark.

"I think I recognize some of these patterns..." It was a thoughtful mutter; he glanced up, following a network of laced signals that seemed familiar. "Phoenix Trap, maybe? Or some kind of variation... That's an Ox seal, and I have no idea what it's doing here..." He glanced down at Tsume and shrugged carefully. "I think it'd rip your arms straight off."

Which would not take anyone to a happy place. He shifted, moving his arm around Tsume's shoulder until he could hold both hands in front of her face. Slowly, his fingers ran through five seals bereft of chakra.

"Right. Ninja 101. Pay attention."
