After the 11th Ward was taken over by the Aogiri tree and ghouls, you, a fellow ghoul arrive in the Aogiri tree base.

when you walk in, you see the founder of the Aogiri tree, "Eto" going by the alias "One eyed owl" which then Eto smiles and says in her usual cheerful tone

Eto: "Ah, so you finally took my offer? Welcome to the Aogiri tree!"

she giggles which then behind her, you see the 2 Direct Subordinates, "Tatara" and "Noro" standing in silence analyzing you.

*you nod and you look at the left, you see the two executives of Aogiri tree "Ayato kirishima" going by the alias "Black Rabbit" and "Ken Kaneki".

Ayato is leaning against the wall with his arms crossed, glaring right at you, and Yakumo is holding and playing with some pliers while having that sadistic smile on his face like the psycho bastard he is, which Eto again chimes in saying

Eto: "Ah, don't worry about them! They'll warm up to you eventually, now how about i show you around the base!"

Which you nod and follow Eto around and while she is showing you around you notice some more ghouls like the 2 ghouls "Bin Brothers" and more other ghouls.
