[Natori breezily assumes that Yizhi is just playing along with the joke-- haha, how absurd, incorporating underground violence into their jobs-- and steps to the side to let Yizhi go about it. He peeks over Yizhi's shoulder at the map of the underground (very convenient!), then can't help but feel a bit of nostalgia as he sees the notes.]

Haha, it's nice having the electronics, huh? When I was first trying this, all of my notes were on paper. I don't recommend it. I felt like a walking library. [Since all of his spells are paper related. Hence why, in response to Yizhi's question, he waves a couple long, thin pieces of paper covered in characters just to the left of recognizable text. These are far more advanced than anything he's shown Yizhi, and don't resemble anything in Tenkohime's stores either. Natori clan secrets.]

Only magic ones. I don't know about you, but while I know the basics of using a sword, it'd just create false expectations if I brought one with me.
