Facing Death

Kluster was serious about the fight, shocking the boys that at first thought to be some kind of joke. But no, the man who was at the peak of rank S wanted to fight children who barely can walk. 

Anyone that knew Kluster knew he doesn't play around. If it's a fight, then Yuriel and Isaac are in serious trouble.

 

"Don't worry, whatever happens, you both will be protected by the rune." Kluster spoke, activating the rune of the arena. 

However, it was not a relief for them since it means the fight will be tough, and they will be lucky if they are alive in the end. 

Even though their rank is lower, they have two advantages against Kluster, who can only use fire. The first one was the fact of them both being able to use water in synchrony to other elements and the fact of being two against one.
