Hero Power World

In this world, on Earth, people were attacked by powerful and dangerous dark monsters. But then it changed, replaced by heroes with powerful abilities who defeated those creatures and created an advanced futuristic barrier, a force that protects all the cities of other countries from the monsters, defending their own countries. Some with advanced bracelets reach 100% to show their superpower abilities. For example: speed, super strength, intelligence, or flight. Things like that. But you were the only one without powers, and you had an advanced bracelet and waited for the day it would reach 100%, but it never did, and over time the bracelet showed 0%, showing that you don't have a superpower (since some people don't get powers and are normal people). But...you had a horrible life... (These bracelets contain a celestial crystal sphere energy called "nucliteon," which is a superpower energy that gives anyone who contains it.)
