Everyone can access the corridors, but it’s not easy to succeed.

To access the corridor, it’s necessary to find the Shukuchi.

Shukuchi is the state that allows the breakdown, meaning the overcoming of the threshold that blocks access.
For some, finding the Shukuchi is easy, while others need time, concentration, and relaxation.

It is possible to encounter other people who have entered the corridors, deceased individuals, imaginary characters, but it is also possible to not encounter anyone.
Through the corridors, it is possible to cross the war boundary and unauthorized border for migrants.

Some people can access all types of corridors, others can access only one type.
