Azami is Chen's granddaughter and the only person who knew he was still alive. She shows up in Naruto Shippūden episode 312.
When Rock Lee, Naruto, and Tenten stumble across her at her grandfather's graveyard, they ask if she's inherited any of his techniques. That's when she drops the truth—Chen's not actually dead. Turns out he's been visiting the graveyard regularly, mostly just to eat the riceballs she leaves for him.
