嗜血萝莉
[shì xuè luó lì]
This nickname '嗜血萝莉' (Bloodthirsty Lolita) combines two very contrasting ideas - one, a reference to 'Lolita', often referring to a cute, youthful style of dressing popularized in Japan; and the other is a blood-thirsty personality. It could indicate someone who admires both cuteness and strong personalities or fantasy elements involving gothic lolita aesthetics.
