Cleaners?

Ban hesitated for a moment but after hearing the music, the hesitation immediately disappeared like a bubble, followed by the courage to deal with his enemy. 

Swoosh! 

The beautiful Poisonous Butterfly Dagger pierced Brok's neck as if it was butter. 

Not even a moment had passed when his eyes immediately turned lifeless while his summoned monster from far away had also disintegrated into many particles of light. 

He was instantly killed by the dagger's potent poison and based on the current expression on his eyes, it looks like the illusion he saw was not a pleasant one. 

At this moment, Brok's face suddenly started to melt. And a moment later, Ban saw a face which he was familiar with. 

It was the face of the guy who tried to bump him earlier when he was still in Joana's store. 

He planned on getting his revenge, but who knew he would be able to obtain it this way.
