The alpha's woman

　　"I see you have a lot of guts pack in you that you are asking us such stupid questions." The Ninja who had given the driver envelope full of money said to Demon. "Say that again when you are at our mercy." He added.


　　"I have so much confidence in myself and I know I can beat all of you here at once," Demon said. "Before I kill all of you, would you mind telling me who sent you to kill me." He said and brought out his phone from his pocket, typing into it without a care of the Ninjas that surrounds him.


　　"Someone who knows who you are, someone who wants your blood and wants you dead. You will get to meet the person soon before your death." The same Ninja told Demon.


　　"I always warn anyone that wants to fight with me." Demon said softly, putting his phone back into his pocket. "Leave here if you still wish to live or you die in my hands."


　　All the ninjas laughed out taking his words for fun.
