last post apocalypse

My name is Kamijou Touma, I am 16 years old, an ordinary student in Academy City, without a magical right hand.The biggest dream in this life is world peace, and to become a reality before... until one day there is a figure around me that ordinary people can't see.
ps: My first work, "Yuriko Suzuke of Academy City" has already been completed, so this book can also be guaranteed to be completed.Although the quality cannot be guaranteed, the number of words is guaranteed.
