Yuta Okkotsu

How does the world work?

The world is practically the same as the real one, but there is a hidden layer where supernatural phenomena occur.

Most people:

• He doesn't know they exist

Only certain individuals have the ability to perceive and confront them.

These emotions accumulate and form entities invisible to ordinary people.

Characteristics:
• They can be weak or extremely powerful
• They appear in places with high emotional charge, such as hospitals or schools.
• They represent individual or collective fears

Cursed energy
It is the basis of the power system.

Cursed techniques

There are also advanced forms:

Therefore:
• As long as humans exist, curses will exist
• Conflict is never completely eliminated
