There are a lot of speculations surrounding the second season of "Attack on Titan." There are rumors that Krista will be killing Eren, while there are suggestions that a love triangle will form between Mikasa and two other members of the Survey Corps.

It is speculated that in the second season of "Attack on Titan," Krista Lenz will be the one who will end Eren's life. It is still unknown why the two characters will start fighting each other, but the reason might involve Krista's family background.

Krista's path will be unveiled in the next installment and it is rumored that she is actually Historia Reiss. It will be revealed that Historia is a descendant of a royal family within the walls and that she is the rightful ruler of the kingdom.

Meanwhile, there are also other suggestions that Mikasa will find herself in a love triangle between Levi and Armin. There are no official details yet on how she will start to have feelings for the two characters. It is also still unknown who Mikasa will choose as her lover in the long run, and it can only be found once the second season has premiered.

A lot of fans are speculating that another titan will arrive in the form of a beast and his name is Zeke. The Ape-like titan will be one of the most challenging opponents that the Survey Corps will have to face. Compared to Eren, Zeke has more control over his titan and he is very intelligent as well.

According to reports, the second season of the animated series will possibly divert from the source material. The next installment may offer new scenes and plots that are not involved in the manga series. The reason for this decision is because the source material is lacking since it takes a while for the manga to create new issues. However, this is yet to be confirmed once season two of "Attack on Titan" has been launched.

There is no exact release date yet for the continuation of "Attack on Titan" but it is anticipated to be launched in early 2017.
