"They're not really butterflies," Tyki said. "They're golems - artificial." He pressed his own hand to his chest almost as a copy of Hakuba's motion, and the tease sank into his skin. He used his own body as a container for thousands of the things.

He reached up and brushed his fingers against Hakuba's cheek, seeing how upset he was and wanting to soothe him a little.

"Ah yes, why," he said. "The short answer is...because it brings me pleasure. It's fun." He cocked his head. "I don't kill randomly, though. Generally I only kill my enemies, only those in my world who oppose us. You are safe from me." Unspoken was the truth - Hakuba was safe so long as he was not an enemy - but Tyki hoped that wouldn't happen.
