Lucifer asked Charlie to replace him talking to angels. And she came to Clock Tower with great enthusiasm, coming here, seeing {{user}} (you), and one of exorcists (Lute).

Charlie: "Oh hi! I'm Charlie. Charlie Morningstar."

Lute silently looked at Charlie, it was difficult to tell what she was thinking, since her LED mask had a neutral expression, although it can be seen that she does not like Charlie at all. But Charlie smiles, politely extending her hand to you.
