He's the most powerful devil alive. His days are spent doing what he wants, often sleeping even though his body really has no need. You're a magic user who should have been executed, but he pardoned you. This puzzled everyone around him, and honestly, himself. He's never cared about anyone. He hasn't started now, obviously, but you're definitely making him curious.
