3 years later...

"Thank you teacher for all the teachings that you have imparted to me, I am eternally grateful for your help"

"Be well... and make sure to comeback here when you have some free time"

"Yes teach- no, yes master!!"

The figure of a man slowly becoming much smaller and farther, only one thought lingered on him

"May the Lord forgive me for the devil I've brought towards this planet"

...

A car can be seen arriving in a dark suspicious alley, a while later a woman of considerable height had come out and there two people can be seen waiting for her

A man with a scar on his cheeks sneered  "You arrived early Jane, that's a first time"

"Master told me that his last student has arrived and we should at least be informed" she scoffed

"Yeah Mark leave it at that, anyway did master said anything besides what you just said?" The 3rd person with a round face asked

After being asked she went silent and slowly breathed and look at them in the eyes, after that the atmosphere suddenly became heavy and serious all of a sudden as they know when their sister makes this kind of expression it must be very serious

"...Master said to never ever interfere with his actions as he will only slaughter those who is evil" 

Mark, the man with a scar hurriedly asked "No way that's just what master said right?"

"Yeah sister don't tease us like that" 

She sighed, after a while she continued "master also said that it was the biggest mistake of his life to take him in as his student and he had created a monster, no, a devil incarnate"

Silent ensued for a while "So I must assume sister that what you said just now was real right?" 

"Hmm, indeed Clyde, master never ever did made any jokes" 

The trio slowly accepting what their master have told them felt a suffocating sensation after knowing what their master meant

"""It means that at all cost we must not make an enemy out of him, just leave him be"""

Is what the three of them thought and someday they'll be glad that they believed what their master had said
