The Fire Ant Girl (火蟻女) was a demonic assassin sent by the Master to kill Lan Ling Wang. She was often in the appearance of an innocent high school girl to seduce boys and attack them when their guards are down. According to Ye Si Ren, the Fire Ant Girl was a being mixed with spirits and fairies, and was therefore a very formidable weapon. Since she wasn't human, she could only speak ant language, though she understands human language. To maintain her health, she needs to eat sweets. She was later killed by Zack who was sent by the Master to assassinate her for her failure.
