Hi Kaworu-kun. If it's all right with you, I need to talk to you about something important. Do you remember a few months ago when I told you that my work as a hero meant someone could come after the people I care about? Nothing's happened, don't worry. I just wanted to tell you more about that.

There's this old enemy of mine from home in Trench. He may have seen us at the tournament. I fell asleep in one of those Sleeper cocoons and was home for a bit, so I learned new information about him. He's more powerful now than I thought.
