There's no need for you to tell me. I've more or less confirmed it moments ago… Upon hearing Anderson Hood, Klein wore a calm expression as he mumbled inwardly.
Back when he encountered Reinette Tinekerr in the spirit world where he saw her massive true form and gothic-styled castle, Klein already believed that she wasn't someone to be messed with. And with Miss Messenger almost killing the Strongest Hunter with such ease, it made him believe without a doubt that she was a demigod, a Sequence 4 at the very least!
A demigod is willing to help me deliver letters for a gold coin per trip? It's obvious that things aren't that simple. Miss Messenger must have her motives; of course, I can't disregard how I'm always encountering all sorts of strange matters. It might've piqued her interest, and she doesn't mind being a messenger since she happens to be free…
