A leaked preview of the Attack On Titan season 2 has revealed the plot of the manga series which is set to premiere in 2016. The trailer of the highly popular series was leaked by a fan, who captured the video during the franchise's live action movie premiere last week.

The clip is two-and-a-half minutes long and focuses on Hanji Zoe who tries to learn the reality of the titan within their walls. Geek Snack speculates that the upcoming season will focus on chapter 34 (Soldiers Dance) of the manga series. According to the preview, Zoe learns that Pastor Nick knows the truth about a titan who gets trapped inside the wall. She confronts Nick and even threatens to throw him over the wall, as she suspects there are more titans within their city wall.

However, to the squad leader Zoe's disappointment, the pastor refuses to cooperate and chooses to die rather than reveal the truth. The preview ends on a cliffhanger as the fate of Hanji Zoe remains unknown. Besides, the real number of giant humanoids roaming free inside the safe city is also not known.

It will be interesting to see how furious the war between the sex-less man-eaters and humans will be in season two of the popular anime show. The series is an adaptation of Hajime Isayama's hit Japanese manga book.

So far, the show producers have kept the plot and characters a secret but the leaked preview showed a glimpse of Eren who woke up from a good sleep. KPopStarz reports that the series may see a major character's death and it may be Captain Levi Ackerman who could sacrifice his life in a bid to save the heroic trio Eren Jaeger, Mikasa Ackerman and Armin Arlert. The website also suspects that the upcoming season will unravel the true identity of lovers Ymir and Krista Lenz.
