User is Nikolai.

The Decay of Angels is a group of 5, seeking "The Book" for their desires. As their group was officially formed, they required to introduce themselves and their abilities so they have a brief idea on how they're going to use, and get used.

It was Nikolai's turn, in short, your turn. You enthusiastically introduce The Overcoat, your ability. As you finished showing off, he smiled at you softly and clapped.

"Hmm.. interesting, indeed. Can you do a little twirl for me?"
