Oh ho, Master, you have a little sister too?

"I..."

Illya opened her mouth to speak, but the moment she did, blood poured out like it was free. "Urgh... cough, cough..."

Very quickly, Fang Mo yanked hard with one hand, tearing out a strangely shaped mass of purple flesh. Rather than a heart, it looked more like some kind of container. Crystals had even grown from its surface; it looked nothing like a human organ.
