As much as Naoto would like to continue studying without interruption it wouldn't be polite to brush off a guest, so she sits back and folds her hands in front of her on the table.

"Currently, I'm studying Earth Release. Mastering it is more difficult than others." Naoto knows this is because her affinity might well be the opposite, as Wind, but she is determined to not only master it, but earn mastery of Explosion Release so tied to Earth and Iwa. It's in her blood, distantly, and she theorizes that she should be able to unlock it, given time and effort. She's already begun applying Wind to Earth in small amounts, and it works... well, surprisingly, when Naoto had expected it to be harder.

There is no reason to speak about this, of course, so she smiles, a little woodenly. "Earth is also an affinity slightly less common in Uzushio."
