"A Demon"

Axelle's black corrosive liquid flew so fast that amid the chaotic battle, almost no enemy noticed the flying liquid with sizzling noises. 

And Axelle's control over the liquid was also so good that he didn't let even a drop of it fall onto the others. 

With Ainsley guiding Axelle in real-time, Axelle managed to locate the group-stealth ability user perfectly, and without a word, he immediately dropped the liquid on top of the target's head. 

He couldn't see the person nor sense the target, but he believed in Ainsley's judgement. 

When Ainsley said, "Now!" Axelle didn't hesitate to drop the corrosive liquid that he produced. 

Tzzzzzz. 

An intense sizzling noise sounded before the group-stealth ability user's scream pierced his friends' ears. 

"AHHHH! It hurts! Ahhh! Ah!"
