A video said to be the trailer for "Attack on Titan" season 2 recently made the rounds online.

Reports claim that a fan uploaded on YouTube the preview that was released during the opening day of the "Attack on Titan" live action film. The two-minute clip centers on the story arc of Hanji Zoe, who is trying to understand the existence of the titan within their walls.

The clip also shows that Pastor Nick has an idea why the titan stays within the walls. Zoe confronts the pastor to extract the truth from him. But the pastor does not seem willing to talk about it, so she threatens to hurt him. She also feels that there are more titans hiding within their turf.

Still, Pastor Nick refuses to reveal whatever he knows about the titan and tells her that he would rather die than share what he knows about the titan stuck within their walls. But the trailer ends with an unanswered question, after Zoe demands to know the actual number of the gigantic humanoids existing in the city. It means that fans of the series must wait until the second season of the anime adaptation of the dark fantasy post-apocalyptic manga is released.

The trailer is dubbed entirely in Japanese, but the YouTube uploader added English captions said to have been lifted from the chapter 34 of the manga written by Hajime Isayama.

"Attack on Titan" anime is directed by Tetsuro Araki and produced by IG Port's Wit Studio. It first premiered in Japan in 2013 via MBS, then Funimation brought the series to North America in 2014.

The release date of "Attack on Titan" season 2 has yet to be revealed, but it is slated to premiere sometime in 2016.
