I won't forgive you!

After "stop that!" it has to be the most common line of dialog in anime: "I won't forgive you!"

I wanted to save "I won't forgive you!" for a special occasion, and this is it. Most characters scream the line, but Sojiro can make it sound infinitely more deadly with a calm voice and a little smile.
