[Ed's eyebrows went up a little bit at the mention of shinobi, remembering his talk with Obito and how the boy had mentioned something similar about how useful automail would have been in his world. The headband Neji wore... he must have been from the same world.]

It's surprising how some worlds have never heard of automail--after the civil war, a lot of people needed limbs so the demand for it went up. There's a lot of technology in a place like this that we don't have, but automail's been around for awhile.

[He nodded at the offer for instruction however.]

Yeah, picking up something new is always good. I'd take you up on that.
