Dorohedoro
This is a story about Kaiman, who has no idea who he was before he was turned into something else by a Magic person. This change left him with the head of a reptile and a burning desire to learn the truth about who he truly is. Accompanied by Nikaido, his female companion, he seeks down Magic Users in "The Hole" and unceremoniously chomps on their heads in the hopes of determining who put him in this state. They observe this "second man" inside Kaiman's head one by one, and as he extracts them from his mouth, he asks them all a question... "What did the guy inside my head say?"
