Danger

"Aaaahhhh!"

The sword impaled the guy's heart. This attack could only be done by them because it took advantage of Ardagan's indestructible body as well as Anna's extraordinary strength. 

"Impossi…" The guy glared at them until his consciousness faded away.

Noel took a deep breath and pulled out his sword. "As expected, a Spirit Wielder is a bit harder to fight against an Advanced Level Demon. A human is indeed weaker than a demon in physical abilities, but they're far trickier and harder to kill."

Noel glanced at Anna to check her condition. She had been running all this time, so she must be pretty exhausted. That was also the reason why Anna couldn't overwhelm this guy in the first place. 

"Are you alright, Anna?" Noel asked.

"Yeah." Anna nodded while walking to him as if she was completely fine. 

However, Noel could see her body shaking to the point her feet gave up.
