Gao Wu, I Use Cause and Effect to Change the World

When the gray finch flaps its wings, it does not sing a hymn. Talent Karma and Puppet. She doesn't save people, she only kills those who deserve to be killed - with their own knives, their own hands, and their own sins. Don't talk about justice, just talk about "interesting". A final warning from the villains: She won't kill you, she'll make you do it yourself.
