Grandfather Ackerman

Kenny's Grandfather was the grandfather of Kennyand Kuchel Ackerman, he was also the great grandfather of Levi Ackerman. At the time, he was the only living member of the Ackerman bloodline that had any idea of why the Ackerman bloodline was being persecuted.

Appearance
He was a sickly and frail old man, with limp, light colored, neck length hair. He had weary eyes, a pointed nose, and a mustache that formed into a beard. Due to his health, he wore loose fitting clothes and appeared unable to leave his bed.

Personality
In an attempt to protect current and future members of the Ackerman family, he intended to die without ever telling anyone the secrets of the Ackerman bloodline's previous life by the King's side.

The Uprising arc
On his deathbed, Kenny Ackerman visits him, for what will likely be the last time. He tells him that he found his sister, Kuchel Ackerman, and that was impregnated by a customer. He also informs him that the Military Police that were snooping around have been taken care of.

Baffled at the state the Ackerman family is in, he questions his grandfather about how things came to be that way. In an attempt to sweet talk him he goes on to say, "I'm your cute little grandson, aren't I?" Gasping, he sits up and asks if the cute little grandson he knew is known in the capital as "Kenny the Ripper." Though originally intended to keep the Ackerman secrets to himself, seeing the state that the Ackerman family is currently in, he begins telling Kenny what he knows.

He starts off by clarifying that the royal government doesn't hate the Ackermans, but fears them instead. Due to the King's inability to control them. He goes on to say that despite being born within the Walls, he is certain that they served at the core of the royal government; with the duty of ensuring humanity's continued survival. He mentions how most of humanity if from a single bloodline, while a small group is from separate bloodlines. Because of the those from the differing bloodlines, they posed a threat to his rule, the king was unable to see his ideals come to fruition.

The King's ideal rule was to rewrite humanity's memories by erasing the history of the past in order to bring about peace and order.
