To teach you a lesson

The man almost choked on his own breath as the words written by blade melted into the background. 

The man immediately gripped the railings of the rooftop he was currently at and looked down. 

At the top of his voice, the man shouted. "What did you just say? Moon Chaser! I definitely read that! Are you trying to insult me?! Just wait and see I kill your current owner! I will definitely take you back and teach you a lesson!" 

But no matter how loud he shouted, no one can hear him. His voice got drowned in the endless silence of the city. The man just forgot the most important thing. 

Because of the restriction placed on him by the Blood Tower, he could not materialize his appearance in the lower floors. His real body was still in the upper floors. Only his consciousness drifted off to this floor, hence his actions and appearance are constricted.

The blade must have known this was the case since it outright insult him in the face.
