Transformation, Reversal!

For a work I completed in collaboration with a friend, he took the lead in writing and I revised it. The final interpretation of the work rests with him, and I only distributed it on my behalf. Although this is a short story, it was very helpful to me in improving the world view of Survival Day, and I also borrowed a setting. In short, this is just a test written by me and my friends. If you don't like it, please don't criticize it. Suggestions for modification are welcome! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
