Oji is a mute cat born from a Cather (Cat with wings that lacks a voicebox) named Xiji and the god of the void itself: Ojamora. He has sibling (ref later) that is evil, because that's how it works obvously. Due to his father, he lacks the wings of a cather, but instead had the ability to summon void spikes from thin air. They are formed from the rapid compression of molecules that are teleported from random places in the universe. When in Ozanqu (The dream dimension), his voice is like a soft, young boy, who has never seen a terrible thing despite the fact he was tortured the first half of his life and then thrust into A- haha not gonna tell you cause that would ruin all 22 books, haha....
