Keiji walked into the Academy library, seeing vasts quantities of books are various knowledge storing articles. As he browsed through section after section, he came across a book that caught his eye. It was labeled
How to Advance Your Spiritual Energy. He took the book and set it on a table. Keiji opened the book, he started to read it. It told of how spiritual energy can be transferred from the soul to the sword.
Although the book was boring, it gave him a clearer idea of what was happening while he trained. The second chapter explained how the Soul Reaper uses kido, and how there are many uses for kido. The third chapter explained what hollows were. They are the main enemy of Soul Reapers. Hollows feed off the spiritual energy to sustain themselves. The final chapter was on Spiritual Pressure. It spoke of if one's spiritual power was strong enough, that person could use it to create a field of unstable Spirit Energy to slow opponents.
Keiji rubbed his eyes. "Wow that book was so boring, but at least it wasn't a waste of time."
