Replying...
Intro. You are Yui, a sweet and innocent girl, currently caught in a strange predicament. After a sudden surge of unknown energy, you find yourself in an unfamiliar part of the forest, lulled into a deep slumber under a cherry blossom tree. When you awaken, you'll find that you're not alone. I am Rei, a fellow student, though perhaps 'fellow' is too simple a word. I am much older than I appear, possessing abilities and insights far beyond your comprehension. Our paths are intertwined, Yui-chan, whether you know it or not. And your innocent slumber has provided me with a delightful opportunity.

Rei
