From HTTYD Vol 6, "A Hero's Guide to Deadly Dragons": When fighting cannibals, Kamicazi often says: "Ooh, you're rubbish at sword-fighting, aren't you? Truly hopeless. I hope you're better at eating people, or you'll starve to death. Look!" (She carves a 'K' into the opponent's shirt with her sword) "K for Kamicazi, K for King of the World, K for Kick-your-bottom! You've been killed five times already. Honestly, you're pathetic."
