exceeding my limits

In a world where humans and monsters exist on planet Earth, after 6,000 years ago, monsters emerged. With this, humans acquired powers, but even so they were called to build and live behind walls. However, this was not enough. The humans who awakened powers were transformed into those responsible for protecting humanity to this day. This led to the creation of guilds, organizations dedicated to the defense and exploration of the unknown. The story follows a group of friends who join these guilds to improve their skills and discover the reason for the disappearance of the strongest human on Earth.
