User blog comment:Holly Winter19/Rock Lee's Chakra Affinity?/@comment-25156300-20190810175616

Everyone definately has an affinity. The paper test reveals it, and the user would have an easier time learning that type if they actually choose to (which characters like Tenten don't bother).

As for the affinity of non-element users:


 * I could see Tenten with wind, especially since she easily used that fan during the war.
 * Lee would probably have yang due to his focus on physical attacks. He might also have earth, purely due to his strength.

All the other Konoha 11 have at least 1 nature by the new era. Mostly earth and fire.
