“If you’ve been following recent events in the Attack on Titan manga, you’ll have seen that it seems to be validating some originally far-fetched sounding theories based on No Regrets, Birth of Levi spin-off manga. Probably related to this, there’s been talk about Levi’s age. Enough talk that the manga author has decided to comment on how old the popular character is.
From the official Twitter account:
“There is a rumor that says Levi is 30 years old. I checked and Isayama sensei said Levi is older than 30, but would not go into details because it may be related to the yet untold story.””
