Not a summoning?

"Huh?"

Sparrow felt a bad premonition in her heart with Kiira's words; however, she suppressed it and coldly replied, "I will kill you and see what will happen."

After saying those words, Sparrow increased the force in her grip around Kiira's neck.

As she summoned the demon king, she originally suppressed power was still decreased and overall her power was almost equal to Sparrow. So, Sparrow was easily able to handle Kiira with a single hand.

"You can't kill me...If you kill me, the summoned demon king will go berserk and kill you for sure,"

Even at that moment, Kiira didn't feel any fear towards death as she said that if she died then Sparrow and her companions would die for sure.

"I don't believe you," Sparrow didn't believe her words as she thought that Kiira was just delaying time and directly crushed Kiira's windpipe.
