A Shocking Gift to Nick~

About my identity, some know a little,while others know more but no one knows my real identity and my history. Why talk about others, I, myself don't know about my complete identity? 

Before the Horn Mountain incident I used to question myself: who am I ? But now the question and mysteries have been changed to: what am I?

I can't waste my time thinking about all these sorts of nonsense so I locked it safely in my mind. It wasn't time for me to find the answer yet.

"Okay ,don't regret it later on. Then I have rules that you should follow strictly with no excuses…" I told him the rules that I had made to my subordinates.

" I promise never to betray you or go against you. I will keep my word until death bed. I will do my best to fulfill the task you give me, won't slack off. But give me spare time to enjoy my life too." He chuckled at his last statement.
