...It has been long.

A single calamity awakens from a long slumber.

I am famished... First, I shall seek a feast. A fresh and delicious spiritual energy to satisfy me. No, however, this form is far too conspicuous for my liking.

The black mist clears, and the grotesque hands melt into the darkness. The massive body shrinks, transforming into the shape of a single girl.

Hmm, this is far too young.
