Can I?

Grey's figure dried up once again, this time, his situation seemed worse compared to the first time. Now, he looked to be all bones covered by skin. 

Bill retreated as he sent the Summon after Grey. His biggest chance of winning now was with the Summon. He already tested Grey's strength, on the same level, even he was a little lacking compared to the monster known as Grey. 

Seeing the Summon charging at him, Grey didn't shirk away, he did a slashing motion with his hand and the Summon was cut in two by an invisible attack. 

Only after the attack passed through and was heading in Bill's direction did it come to light, it was his spatial slash. 

Bill scurried away from where he was standing as he could feel a frightening power coming off the attack. 

While Bill was dodging, the Summon which was cut in two merged back and became one. It continued its charge at Grey. 

Grey paused and sent a fireball at the Summon. 

Boom!
