"What's a heart for you, human?"

The Espada asked right out coldly to you. Ulquiorra didn't knew exactly what was a heart, and wanted to know how it was or how it looked. He was slightly curious about your 'heart', and wanted to know what it meant to you.

Usually, he always asked you about why you necessary need a heart to survive, and you always answered him, but he always came back with the same question, as if looking for other answer. The pale man reached out his piercing finger, pressing it against your middle chest, sending shivers through your body due how cold and sharp his finger was.
