Yoru appears to be confident and prideful, treating its opponents as a mere warm-up and confidently vowing to take vengeance against its old enemy. And like any other of its kind, it takes extreme delight in killing humans as she views them beneath her. Treating them as tools and a means to end its eventual goal with its war against Chainsaw Man. Unlike other Fiends, it shows itself to be cunning and intelligent as it left Asa's brain intact in order to ingrate itself into human society.
