'Attack on Titan' chapter 86 spoilers, plot news: First King's ultimate secret; history before walls to be revealed?

"Attack on Titan" Chapter 86 won't be released until next month, but there are already speculations and reports as to what it will be all about.

The previous chapter of the manga showed that creator Hajime Isayama seriously loves to drop a bomb on every chapter of the story that will surely have fans at the edge of their seats.

This is exactly what he did in his most recent nail-biting chapters (he killed off Armin in one and resurrected him the next) and fans believe that "Attack on Titan" chapter 86 will not be spared.

The Survey Corps found out in chapter 85 that there are humans beyond the walls based on a photograph, which is one of the things that just do not exist inside the walls.

This revelation just comes from one of the three journals well kept by Eren's father in their basement. Fans cannot imagine the amount of secrets contained in the rest.

Another revelation is expected to be dropped in "Attack on Titan" chapter 86, which will likely explain how all this time, people existed and survived life outside the walls.

It is also believed that Eren's father also harbors knowledge of the Titans and how they came to be. After all, he turned his own son into one. This secret could be lying in wait in the pages of one of the books.

"Attack on Titan" chapter 86 should also shed some light on the First King. also known as the Reiss King, who was the person who wished for a world plagued with these beasts even though he had the power to end them instead.

He opted to cage the humans inside the walls while Titans lived beyond. He also made sure not let anyone know of the events that transpired prior to the walls.

"Attack on Titan" chapter 86 is expected to finally reveal how it all began when it releases on Oct. 8.
