It's time to switch gears folks. We know the wait for "Attack on Titan" Season 2 has been near absurd, but we already reported that the production of the anime's new season will not begin until the release of Volume 14 and 15 of the manga. Given that timeline, the "Attack on Titan" Season 2 release date probably won't be until August 2015. In the meantime, an "Attack on Titan" prequel spin-off known as "No Regrets, Birth of Levi" is slated to arrive in December 2014.

As the title "Attack on Titan: No Regrets, Birth of Levi" suggests, the spin-off anime will revolve around Levi's Survey Corps journey before he is joined by Eren and Mikasa. As we begin to understand more about the plot, some fans are demanding to get an understanding on the precise age of Levi Ackerman. Depending on who you ask, Levi's age ranges from 25 to 35-years-old. In fact, the debates have been so popular that it has prompted the manga team to post a Twitter response to somewhat clear the matter.

"There is a rumor that says Levi is 30 years old," wrote the official @ShingekiKyojin Twitter account. "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."

What is this untold story that the "Attack on Titan" writers speak of? AoT fans that have been paying close attention may have noticed that Mikasa and Levi may be related. Other than the somewhat similar physical traits such as black hair and superior athleticism, both Mikasa and Levi possess the Ackerman last name. This is where Levi's age comes in: depending on how old Levi is, we can determine his relation to Mikasa.

According to the manga writers, Levi Ackerman is definitely older than 30 years old. Based on Levi's profile on myanimelist.net, he is 34. The first theory is that Levi is Mikasa's uncle, or the brother of Mikasa's father,  given that the Ackerman name must come from the dad. However, the second theory is significantly more shocking as it claims outright that Levi is Mikasa's father. Evidence supporting this theory is extremely weak, but a father at 19-years-old is not beyond the realm of reality. Due to the terrible mortality rate of Survey Corps soldiers, the truth of Mikasa's father may have been concealed to give her a normal childhood. If the theory were true, "Attack on Titan: No Regrets, Birth of Levi" spin off would be a great time to address it. Could that be why the studio is dedicating a special spin-off for the Survey Corps leader?

According to ShingekinoKyojin.wikia.com, Levi was original a thug in an underground city that was located right below the surface of the capital before he joined the Survey Corps. Stay tuned as we bring you more info on Levi's background as the "Attack on Titan: No Regrets, Birth of Levi" anime draws near.
