Training of the Heart: Kai's Training Begins

Beginning
A boy with semi-long blackish-brown hair and light brown skin slowly opened his eyes to find himself alone in a empty room with no door.

What am I doing here? he thought. He looked around the room, and found a single letter sitting on the floor a few feet away. He opened it and read it's contents.

''Dear Kai,

Welcome, today is the beginning of your training to become the Sage of Hearts. The Sage of Hearts is the guardian of hearts and it is his or her job to protect them from danger.

This may sound like the job of a soul reaper, and it in fact it is much like that of a soul reaper. However, you have no code of conduct, and nothing preventing you from putting everything you have into protecting hearts.

If you have concerns about this and why you alone must bear this job please understand that everything will be made clear as you progress though the training.

Your friend, the former Sage of Hearts''

Guess I don't have much choice in the matter... considering I probably can't go anywhere until after I finish training... thought Kai.
