Koutarou Amon

The Robed Giant (ローブの大男, Rōbu no Ōotoko) is a mysterious Ghoul. According to Donato Porpora, he can become one of the keys to Haise Sasaki's memories.

He seems to have hostile relations with Aogiri, as he has repeatedly attacked members of Aogiri.

It is suggested that he is related to the floppies, as he is once seen standing over a ghoul who calls out "a......mon....".

Appearance
He is a dark-haired man of considerable height, glimpsed wearing a light-colored robe similar to that of a monk. Most notably, his right hand is deformed -- with only three fingers as opposed to five.

Personality
Little is known about his personality at this time, but he seem to be opposing Aogiri Tree. He also seem to be willing to cannibalize other ghouls.

Nutcracker Investigation
He is first mentioned when Haise Sasaki visits Donato Porpora, at the prisoner's request. He informs Sasaki that there is a Ghoul of personal interest to him, that holds one of the "keys" to Sasaki's lost memories. Though he reveals a name to Sasaki, the scene cuts away to a figure in a tattered robe carrying a staff.

Auction
In the aftermath of the Auction, fleeing members of Aogiri Tree are ambushed. The same robed figure mentioned by Donato stands over a dying Ghoul, who calls out "f... lo... ppy...". The figure mentions "Yasuhisa", and departs from the scene. When the bodies were later discovered by Investigators, there was evidence of cannibalism.

Rose Investigation
The robed Ghoul next appears during Aogiri's ambush of the Quinx Squad, rescuing Saiko Yonebayashi from Shikorae. He displays incredible physical strength and an Ukaku-like attack, as well as a deformed right hand. Saiko thanks the man for saving her, but he flees once her comrades arrive.

Later on, Akira Mado pulls Saiko aside in order to talk to her more about the "robed hero" that saved her. While thinking about this, Sasaki experiences an uneasy feeling.

Haise Sasaki
It has been stated that the two have some sort of connection, as the Robed Giant holds "one of the keys" to Sasaki's lost memories.

Donato Porpora
Donato claims to have a personal interest in him, though it is unknown how or why.

Saiko Yonebayashi
He appears when she is attacked by a member of Aogiri, and rescues her. Afterwards, she expresses gratitude to him but he flees the moment her back is turned.

Akira Mado
Akira seems to have an interest in his case, taking Saiko aside to discuss things.

Yasuhisa Family
He makes mention of someone named "Yasuhisa", though it unclear which member of the family he was referring to.

Power and Abilities
He seems to be a powerful ghoul capable of sending another ghoul away with one hit despite having a deformed right hand. He also seems to be incredibly fast, as he was able to disappear shortly after Saiko took her eyes off of him for a very brief period of time.


 * Ukaku Kagune: He appears to have an Ukaku kagune of decent power, capable of firing off numerous projectiles. These can easily blast holes into another Ghoul's body, as demonstrated during his brief battle with Shikorae.


 * Staff: He wields a large staff in battle, though its exact properties are unknown at this time. As it is wielded in battle against other Ghouls, it is possible that it is actually a Quinque.

Trivia

 * He is the first known instance of a Ghoul with a physical deformity.
