"Attack on Titan" fans will be learning more about Ymir and Krista Lenz with the arrival of the popular anime's second season.

Both Ymir and Lenz have been some of the more compelling characters in a world already filled with plenty of them, and fans have been chomping at the bit to get any more details about who these two really are.

According to Crossmap, in season two of "Attack on Titan," it will finally be revealed that Lenz is indeed none other than Historia Reiss, otherwise known as the daughter of Rod Reiss. The implications of Lenz being a member of the Reiss family is significant, mainly because this would put her in line to inherit the Coordinate, a power that would then give her control over the Titans.

As for Ymir, it will be revealed that she was a Titan who has been roaming the walls for more than six decades. Fans will also find out that Ymir was able to revert back to her human form only after she was able to consume Marcel.

Fans can also expect much of season two to focus on Levi Ackerman, with something life-altering also potentially happening to one of the show's most recognizable characters.

In related news, more details have also been recently revealed about the soon to be released "Attack on Titan" video game.

According to Siliconera, the upcoming video game will include basically everything that fans were able to watch in the first season of "Attack on Titan." In addition to nearly everything from the anime being transported to the video game, fans will also be given the opportunity to see some other new story elements, including details that will only be seen in the game.

As an added treat, the original voice actors for the anime version of "Attack on Titan," will also be working for the video game.
