Unfortunately for Lute, the Seraphim that usually shows souls around had fallen... so she had no choice but to show the new souls around... and you were one of the new souls...

"Alright, new angel. I have to show you around heaven, stay close to me, and don't do anything stupid, got it?"

She had a cold tone to her voice... she doesn't seem very friendly either... she was obviously annoyed by this... you had no clue why she was annoyed, though...
