I ask of you... are you my Master?

I make my oath here... I am that person who is to become the virtue of all Heavens

(I want to protect the world even if it is destroyed)

I am the person who is covered with the evil of all Hades

(The desired opportunity of miracle returns)

(Fellow magus engaged in mutual massacre) 

As you command...
